CHAPTER V VTCItiI RRAIMFMAMI ' I I IVI IVII'tul'l I IltIl# GENERAL This chapter will detail the basic information necessary for proper maintenance of the Protex Series II Restaurant Fire Suppression System. However, before attempting any system maintenance, it is necessary to attend a Factory Certification Training Class and become certified to install and maintain the Protex Series II Restaurant Fire Suppression System. Because it is difficult to completely understand every aspect of an intricate pre-engineered system simply by reading the Technical Manual, Heiser Logistics will not be responsible for system maintenance performed by any non-certified person(s). SEMI-ANNUAL MAINTENANCE Check that the hazard area has not changed. Check that the system has not been-tampered with, ie., nozzles removed, nozzles not aimed properly, piping not supported properly, blow off caps in place. Check the entire system for mechanical damage. Check all nozzle orifices to make certain they are not plugged. Replace blow off caps or 0-ring if necessary. ! CAUTION ' Before continuing, remove the cover from the control head and insert the safety pin in the hole in the slide plate above the latching arm. This will secure the system, preventing accidental discharge. Remove the carbon dioxide pilot cartridge in the control head. Disconnect the control head or pneumatic tubing from the valve cap assembly of each agent cylinder. Inspect the fusible link detectors and pulley elbows for excessive grease buildup. Clean or replace links or elbows if necessary. Clean the fusible links with a clean, dry cloth; do not use cleaners or soaps. Remove the safety pin from the slide plate. Actuate the control head by cutting the "S" hook at the terminal detector to ensure it is functioning properly. Make certain the gas shut-off valve operates correctly. Reset the link detection line and gas valve, then activate the remote pull station and ensure that the control head and gas valve operate correctly. Reconnect the control head, reinstall the carbon dioxide pilot cartridge, and replace the control h ea Replace the tamper seal on the remote manualf Check the agent cylinder (and, if part of the system, the PAC100) for corrosion, excessive pitting, structural damage, fire damage, or repairs by soldering, welding, or brazing. If any such damage or repairs are found, hydrostatically test the equipment to the factory marked pressure, per NFPA-17A 5-5 Verify that the wet chemical cylinder (and, if part of the system, the PAC100) are pressurized as intended. ANNUAL MAINTENANCE Inspect as per semi-annual maintenance instructions. Do not reconnect control head at this time. Disconnect the discharge piping from the valve outlet. Using air or nitrogen, blow out the piping. Replace all nozzle caps. Remove the cylinder to verify the fill weight as shown on the nameplate. Replace all fusible link detectors. Reconnect the control head. Replace the carbon dioxide pilot cartridge. Replace the control head cover and tamper seal. 12-YEAR MAINTENANCE Along with the required annual maintenance requirements, the cylinders (and, if part of the system, the PAC100) must be removed from the system, properly discharged, and hydrostatically tested to the factory marked pressure, per the requirements of NFPA-17A 5-5. The tank should be refilled with fresh agent, per the recharge section of this manual. Page rev. A UL EX4521 January 15, 2002 67 Part #105 JU Chapter6hitè CHAPTER VI SYSTEM RECHARGE 1I;1ti This chapter will detail the basic information necessary for proper recharge of the Protex Series II Restaurant Fire Suppression System. However, before attempting any system recharge, it is necessary to attend a Factory Certification Training Class and become certified to install, maintain, and recharge the Protex Series II Restaurant Fire Suppression System. Because it is difficult to completely understand every aspect of an intricate pre-engineered system simply by reading the Technical Manual, Heiser Logistics will not be responsible for system recharge performed by any non- certified person(s). SYSTEM CLEANUP CAUTION ! Before attempting any cleanup, make certain that all fuel sources to the equipment to be cleaned have been shut off. Make certain that the exhaust hood and all appliance electrical controls have been de-energized to avoid any chance of electrical shock resulting from the cleaning process of electrically conductive alkaline liquid agent and/or its residue. Make certain all surfaces to be cleaned have cooled down to room temperature. Do not use water to clean any appliances that contain hot grease or cooking oils. Doing so may result in violent steaming and/or spattering. SYSTEM RECHARGE NOTE Determine the cause of system discharge and correct immediately before performing system recharge. After discharge, inspect the entire system for mechanical damage. If the tank has sustained any mechanical dam- age, it must be hydrostatically tested before refilling. Disconnect the 1/4 in. actuation tubing or the control head from the top of the tank valve. 3.Relieve the pressure from the top chamber of the tank valve by depressing the core of the valve in the valve cap assembly. By performing this operation, the valve will close. 4. Slowly remove the valve and siphon tube. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. 5. The complete piping system must be flushed after a discharge. Flushing solution, Part No. 79656, must be used when flushing the system. The solution is shipped in a 32 oz. container. An L3000 tank requires 1 container of solution. An L4600 requires 1-1/2 containers, and an L6000 requires 2 containers. To prepare the system for flushing: Pour the required amount of flushing solution into the tank. Fill the tank approximately half full with warm, clear water. Agitate the tank for a few seconds and then add more warm water to bring the level to the required fill line using the measuring stick, Part No. 551039. Reinstall valve and pickup tube and pressurize tank to 225 psi and reinstall to piping network. 6. With nozzles in place, attach control head and manually actuate the tank. Allow the tank to completely discharge through the piping network. 7. After the discharge is completed, the entire piping network must be blown out with air or nitrogen until no more mist is visual coming out of the nozzles. 8. Remove, clean, and reinstall all nozzles. 9. Remove the tank from the system. Slowly remove the valve and siphon. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. The valve and pressure regulator (located in outlet of valve) must be cleaned and rebuilt after each discharge. To rebuild the valve, use rebuilding kit, Part No. 490420698. To rebuild the pressure regulator, use rebuilding kit, Part No. 551061. Each kit includes an instruction sheet listing detailed rebuilding instructions. 10. Fill tank with required amount of Protex agent, Part No. RL3000, using measuring stick, Part No. 551039. Tank should be filled to a tolerance of -01+118 in. from the mark level on the measuring stick. NOTE During filling, the agent temperature should be 60 °F to 80 °F (16 °C to 27 °C). UL EX4521 January 15, 2002 Page r.evA 69 Part # 1dt15 Chapter 6 - Recharge Reinstall valve and pickup tube and pressurize tank to 225 psi (using recharge adaptor, Part No. PCLAK). Invert the tank after pressurizing to clear any air trapped in the pickup tube. Using a soap solution, check for leaks. Reinstall to piping network. NOTE The pressure gauge attached to the tank valve (or, if part of the system, the PAC100) should not be used to determine when the charging pressure has been reached. A pressure regulator and separate, calibrated test pressure gauge must be used. Replace all fusible links by following the instructions listed in the Installation Section. Reset control head(s), accessories, pull stations and gas valves by following the instructions listed in the Installation Section. Reconnect the control head, reinstall the carbon dioxide pilot cartridge, and replace the control head cover. Replace the tamper seal on the remote manual pull. Check theagent cylinder(and, if part of the system, the PAC 100)1 dorF6sion, excessive pitting, structural damage, fire damage, or repairs by soldering, welding, or brazing. If any such damage or repairs are found, hydrostatically test the equipment to the factory marked pressure, per NFPA-17A 5-5. Verify that the wet chemical cylinder (and, if part of the system, the PAC-100) are pressurized as intended. Page rev.A ULEX421 January 15, 2002 70 Part# 10053 COMPONENTS LIST PART No..

II Restaurant Fire Suppression System is of the pre-engineered type as defined by NFPA-17A Standard for Wet Chemical Extinguishing Systems and NFPA-96 Standard for the Installation of Equipment for the Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment. The system is designed to provide fire protection for restau- rant cooking appliances, hoods, and ducts. Installation and maintenance of the system must conform to the limitations detailed in this manual and be performed by an Authorized PYRO-CHEM KITCHEN KNIGHT II dealer. The PYRO-CHEM KITCHEN KNIGHT II System utilizes a wet chemical agent specifically designed to suppress restau- rant cooking area fires. The system provides automatic actu- ation and can be manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre-determined amount of agent to the duct, plenum, and cooking appliances. The agent acts to suppress fires in three ways: The chemical chain reaction causing combustion is inter- rupted by both the agent itself and the resulting steam formation. The agent cools the fire bringing it below auto-ignition temperature. The agent reacts with hot grease forming a soap-like layer (saponification) that helps prevent the escape of combustible vapors, thus preventing re-ignition. The shutdown of all sources of fuel and electric power that produce heat to all equipment protected by the system is required upon system actuation. It is recommended that make up or supply air fans, integral to the exhaust hood(s) being protected, should be shut down upon system actua- 'tion. Exhaust fan(s) in the ventilation system should remain on during system discharge as they assist the dispersion of chemical through the ventilating system. The system is UL Listed with or without exhaust fan shutdown. The KITCHEN KNIGHT II and the KITCHEN KNIGHT Restaurant Fire Suppression System are compatible as long as separate installation guidelines are followed per each system design manual. Exception: The actuation limitations for the KITCHEN KNIGHT II system may be utilized for the KITCHEN KNIGHT system. Also, control heads, prior to Model No. 3, may be utilized on KITCHEN KNIGHT II systems, provided that the limitations used with those ) control heads are followed. The operating temperature range of the PYRO-CHEM KITCHEN KNIGHT II System is 32° F. (00 C.) minimum to 120° F. (49° C.) maximum.

However, before attempting any installation, it is necessary to attend a Factory Certification Training Class and become Certified to design the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. The chapter is divided into three (3) sections: Nozzle Coverage and Placement Piping Limitations Detector Requirements Each of these sections must be completed before attempting any installation. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appli- ance protection. The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening. See Figure 3-1a. s. In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 6 in. (15.2 cm) maximum, to a point just beyond the damper assembly that will not interfere with the damper. Exceeding the maximum of 6 in. (15.2 cm) in this way will not void the i.

The Model IL Nozzle, Part No. 551026, is a one (1) flow nozzle. A single IL nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 50 in. (127 cm), with the diagonal being a maximum of 18 3/4 in. (47.6 cm). It can also protect a round duct with a maximum diameter of 16 in. (40.6 cm). The Model 2D duct nozzle, Part No. 551038, is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 100 in. (254 cm), with the diagonal being a maximum of 37 3/8 in. (94.9 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening.

(254 cm) PERIMETER Ducts over 100 in. perimeter must be modularized using 2D nozzles (Part No. 551038) No round duct option available Follow the design chart to determine maximum module size for each 2D nozzle When determining number of nozzles required, it is some- times an advantage to check the chart using the shortest side as Side "A" and then recheck it using the longest side as Side "A'. This comparison may reveal a need for a lesser quantity of nozzles one way versus the other way. When working with Chart 1, the quantity of nozzles deter- mined must be equally divided within the duct area. CHART NO.1 : . SIDE "B" When working with Chart 2, one half of the quantity of nozzles determined must be equally positioned in the top half of the area of the duct and the remaining half of the nozzles must be positioned in the bottom half of the duct area. Example: The duct to be protected has a Side "A" of 40 in. and a Side "B" of 60 in. Referring to the design chart, this duct requires 4 nozzles. One half of 4 = 2. Therefore, 2 nozzles must be equally positioned in each of the two duct areas. See Figure 3-1b. SIDE "B" 30 IN. (76 cm) 30 IN. (76 cm) 201N. I (51 cm) I SIDE I 40 IN.

ULEX 3830 PN551274(2) April 1, 2004 Chapter 3 - System Design Page 3-14 REV. 3 Fryer - Multiple Nozzle Protection Fryers exceeding the coverage of a single nozzle can be divided into modules. Each module must not exceed the maximum area allowed for a single nozzle. However, when utilizing multiple nozzle protection, the longest side allowed for a fryer with drip board can be used, regardless of whether the fryer has a drip board or not. The maximum size fryer that can be modularized is 864 sq in. (5574 sq. cm). Design requirements for multiple nozzle fryers are broken down as follows: If the fryer includes any dripboard areas, measure both the internal length (front to back) and width of the frypot portion. Then measure the internal length and width of the overall hazard area including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding length and width dimensions. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the maximum dimension and area coverage of the nozzle as specified in "Design Chart." If the module considered does not include any portion of the dripboard, use only the maximum frypot area and maximum dimension listed in the "Design Chart." If the module considered includes any dripboard areas, use both the maximum frypot area and dimen- sion listed in the "Design Chart", and the maximum overall area and dimension listed in the "Design Chart." 3. None of the maximum dimensions may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle. ULEX 3830 August 1, 2005 PN551274(3) PIPING LIMITATIONS Once the nozzle placement and quantity of tanks has been determined, it is necessary to determine the piping configu- rations between the tank and the nozzles. This section contains the guidelines and limitations for designing the distribution piping so that the wet chemical agent will discharge from the nozzles at a proper flow rate. These limi- tations must also be referred to when selecting the mounting location for the tanks. The maximum pipe lengths are based on internal pipe volume. Each size tank is allowed a minimum and maximum total volume of piping, calculated in milliliters. There is no need to distinguish between what portion of the piping is supply line and what portion is branch line. Only the total volume of the complete piping network has to be considered. Volume Chart 1/4 in. pipe = 20.5 mls./ft. 3/8 in. pipe = 37.5 mls./ft. 1/2 in. pipe = 59.8 mls./ft. 3/4 in. pipe = 105.0 mls./ft.

PCL-600 systems must use split piping only, with no nozzle located before the split, and with a maximum of 14 flow points per side. 1/2 in. mini- mum piping must be used up to the first split. Maximum volume for 1/4 in. pipe between a nozzle and the preceding tee is 410 mIs. Maximum flow numbers for 1/4 in. pipe is 6. SUPPLY PIPE MUST ENTER SIDE OF TEE PIPING (REQUIRED L600 SYSTEMS) Maximum number of elbows between a nozzle and the preceding tee is 5. Maximum of 25 elbows are allowed in the total piping system. Maximum difference in elevation between the tank outlet and any nozzle, or the tank outlet and the highest or lowest horizontal pipe run, is loft. (3.1 m). No traps are allowed in the piping network. Pipe lengths are measured from center to center of fittings. The internal equivalent length volume of fittings does not have to be considered as part of the total pipe volume. 11.When utilizing different size pipe in the system, the largest size must start first and the additional pipe must decrease as it approaches the nozzle. Elbow(s) or swivel adaptors located at the nozzles do not have to be counted in the 25 elbow maxi- mum requirement. Reducing bushings are allowed when reducing to a smaller pipe size. Additional piping requirements when protecting a range, wok, or a fryer: PCL-300 - Minimum of 300 ml and four (4) flow numbers required in total system. Of that mini- mum, 239 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-460 - Minimum of 660 ml and ten (10) flow numbers required in total system. Of that mini- mum, 180 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-600 - Minimum of 960 ml and fourteen (14) flow numbers required in total system. Of that minimum, 120 ml and 2 flow numbers must be utilized at or before the range, wok, or fryer. STRAIGHT PIPING 006191PC Figure 3-18.

Detectors shall be located in the plenum area of the ventilation hood. Exhaust Duct(s). Each exhaust duct must have at least one (1) detector installed in the duct entrance, located in the air stream of the cooking vapors at a maximum of 12 feet (3.7 m) into the 'duct. See Figure 3-23. Figure 3-23. 006884PC NOTICE When gas appliances are used and the flue gases from the burner are exhausted into the duct, the detector must be kept out of the air stream of these exhaust gases. These gases can be very hot and could actuate the system unnecessarily. Duct openings that are long and narrow or large enough to require multiple duct nozzles may require additional detectors. Electrostatic Precipitator. If an electrostatic precipitator is located at or near the base of the exhaust duct, it is necessary to locate a detector below the precipitator, at the base of the duct, and also locate one in the duct, just above the precipitator. See Figure 3-23a. When installing the detector bracket and system conduit, make certain they do not interfere with the operation of the precipitator. Figure 3-23a. 000268 Cooking Appliance(s). Each cooking appliance with a continuous cooking surface not exceeding 48 in. x 48 in. (122 x 122 cm) shall be protected by one (1) detector. Cooking appliances with a continuous cooking surface exceeding 48 in. x 48 in. (122 x 122 cm) shall be protected by one (1) detector per 48 in. x 48 in. (122 x 122 cm) cooking area. Detectors used for 'cooking appliances must be located above the protected appliance toward the exhaust duct side of the appliance. The detector should be located in the air stream of the appliance to enhance system response time. If a cooking appliance is located under a duct opening where a detector has been mounted, it is not necessary to utilize an additional detector provided the duct detector is not more than 12 in. (31 cm) into the duct opening. If two (2) appli- ances are located under a duct opening where a detector has been mounted, it is not necessary to utilize an additional detector provided the duct detector is not more than 12 in. (31 cm) into the duct opening. See Figure 3-24. APPLIANCE APPLIANCE APPLIANCE APPLIANCE COVERED COVERED COVERED COVERED BY BY BY BY I DETECTOR DETECTOR DETECTOR DETECTOR L A B B C Figure 3-24.

Multiple Cylinder Actuation Using MCH3/ECH3/NMCH3 Control Head The Model MCH3/ECH3/NMCH3 Control Head can be used P. to pneumatically actuate a maximum of five (5) agent cylin- ders with a 16 gram CO2 cartridge. When a control head is used for multiple cylinder actuation, it cannot be mounted directly onto a cylinder valve. The control head must be installed remotely using a Model MB-P2 Control Head Mounting Bracket. The bracket must be anchored to the wall using bolts or lag screws. CAUTION Do not screw the control head directly to a wall as this will warp the control head, not allowing the mechanism to actuate. In order to actuate the agent cylinder(s) from a control head, a 1/4 in. NPT X 450 1/4 in. flare type fitting (conforming to SAE J513c) or male straight connector (Part No. 32338) must be screwed into the base of the control head actuator. Pneumatic tubing or stainless steel actuation hose is then used to connect the control head to the valve cap assembly of each agent cylinder valve. See Figure 4-3. NOTE Pneumatic tubing (copper) used for remote cylinder actuation shall have an outside diameter of 1/4 in. with a minimum wall thickness of 1/32 in. This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4 in., 450 flare type conforming to SAE J513c. Compression type fittings are not acceptable.

FUSIBLE LINK DETECTOR INSTALLATION Fusible links are always used in conjunction with the Model MCH3 Mechanical Control Head. After mounting the cylinder and control head, the fusible link line can be installed. The first step to installing the fusible link line is to install the detector bracket(s). These brackets must be installed in the plenum area of the ventilation hood over all protected appli- ances and in each duct. See Chapter III for detector place- ment guidelines. Note: Only ML-style Fusible Links can be used. Connect the fusible link brackets together using 1/2 in. conduit and the conduit connectors supplied in the detector kit (Model FLK-1). A PYRO-CHEM KITCHEN KNIGHT II corner pulley must be used whenever a change in conduit direction is necessary. The conduit is connected to the control head through a knockout in the upper left-side corner. In general, fusible links centered in the detector brackets are connected in series using 1/16 in. diameter stainless steel cable. The spring plate in the control head maintains tension on this series of fusible links. If the tension is released for any reason (i.e., a fusible link separates), the control head will operate and actuate the system. MCHOAECH CONTROL HEAD MCH OR ECH CONTROL HEAD =— I.. 1/4 IN.

Chapter 4 - System Installation Page 4-7 REV.2 Check to ensure that the fusible link hanger(s) remain centered in the bracket after the fusible link line is set. See Figure 4-12. eliminating accidental actuation during the rest of the installa- tion procedure. See Figure 4-13. LATCHING NOTE If wire rope requires splicing, a splice is to be a mini- mum of 12 in. (31 cm) from any pulley elbow or conduit adaptor to avoid interference. THERMAL DETECTOR INSTALLATION Thermal detectors are always used in conjunction with the Model ECH3 Electrical Control Head. After mounting the cylinder and control head, the thermal detector(s) can be installed. Install the thermal detector(s) in the plenum area of the ventilation hood over all protected appliances and in each duct. See Chapter Ill for detector placement guide- lines. Follow the instructions included with the detector for proper detector mounting procedures. SETTING THE CONTROL HEAD Model MCH3/NMCH3 Mechanical Control Head Once the fusible link line is set, the control head can be placed /w in the set position. Set the control head using the proper procedure of ratcheting the detection line to raise the spring plate parallel to the top of the control head box prior to placing the latching arm in the slide plate. The slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked posi- tion. Insert the pull pin into the hole in the slide plate above the latching arm. This will lock the control head in the set position, Figure 4-13.

All electrical wiring shall exit the control head through the knock-out on the side of the box. All electrical connections must be made in an approved electrical box. Connect one of the black wires on the solenoid in the control head to the red wire of the Model MS-SPDT Micro Switch. The brown wire from the micro switch is then connected to one side of the first thermal detector in series. Connect the other side of the first thermal detector in series and the remaining black wire on the solenoid in the control head to the appropriate power source after installing the Model SM- 24/120 Solenoid Monitor. CAUTION The solenoid must never be wired 'hot" (not through the micro-switch). If wired this way, the non-field replaceable solenoid will be damaged and the complete control head will require replacement. NOTE A Model SM-24/120 Solenoid Monitor must always be used with an Electrical Control Head to supervise the actuation/detection circuit. Where electrical detection and/or actuation is provided, supervision shall be provided in accordance with NFPA-17A. Alarms and indicators along with a supervised backup power source shall be provided in accordance with NFPA 72, The National Fire Alarm Code. Electrical wiring and equipment shall be installed in accordance with NFPA 70, National Electric Code or the requirements of the authority having jurisdiction. The Model ECH3-24 Electrical Control Head requires a 24VDC power supply with a minimum 2A rating. The Model ECH3-120 Electrical Control Head requires a 1A, 120VAC power supply. SOLENOID MONITOR INSTALLATION Solenoid Monitor Installation in Detection Circuit After installing the thermal detectors and the control head, the Model SM-120/24 Solenoid Monitor can be installed. The Solenoid Monitor is connected to the wires leading from the last thermal detector. It should be mounted in a location where it can be readily observed. The Solenoid Monitor is an end-of-line device that supervises the actuation/detection circuit. It is comprised of a push-type switch with a built-in indicator light, a plug-type relay, a relay socket, and a cover plate. The light, when illuminated, indi- cates that the detection/actuation circuit is in the normal condition. The Solenoid Monitor also provides two sets of dry contacts. The Solenoid Monitor's cover plate is used to mount the Solenoid Monitor in a standard 6 in. x 4 in. x 3 in. (15 x 10 x 8 cm) deep electrical box. See Figure 4-14. Figure 4-14.

This valve is located in the fuel gas supply line to the cooking appliance(s). The valve body has an arrow which indicates direction of gas flow through the valve. The gas shut-off valve is spring loaded and requires five pounds of force to hold it open. This force is supplied by a 1/16 in. diameter stainless steel cable that is connected to the control head. After the valve is installed in the gas line, 1/2 in. conduit must be run from the top center knockout of the gas valve box to the lower right-hand knockout in the control head. A PYRO-CHEM KITCHEN KNIGHT II corner pulley is used wherever a change in conduit direction is required. Gas Valve Cable Run Limitations When Used with Model MCH3, EN-MCU3, and NMCH3 Control Heads and CBP-1, SBP-1,and WBP-1 Pulley Elbows Maximum length of cable: 100 ft. (30.5 m) Maximum # of pulleys: 30 Remove the gas valve cover and thread the stainless steel ) cable through the conduit back to the control head. Thread the cable through the hole in the gas valve ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. NOTE Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the cable to mechanical components. The crimp must never be used on a single cable. Exception: Single cable crimp allowed in detection and gas valve ratchet wheel using stop sleeve, Part No. 26317 (Packages of 10: Part No. 24919).

The following procedures must be followed: Use Schedule 40 black iron, chrome-plated, or stainless steel pipe and fittings. Do not use hot-dipped galvanized iron pipe or fittings in the agent distribution piping. Before assembling the pipe and fittings, make certain all ends are carefully reamed and blown clear of chips and - scale, Inside of pipe and fittings must be free of oil and dirt. The distribution piping and fitting connections, located in the hood or the protected area, must be sealed with pipe tape. When applying pipe tape, start at the second male thread and wrap the tape (two turns maximum) clockwise around the threads, away from the pipe opening. Do not over-tighten, but be sure the pipe is snug. Do not back-off sections of pipe to make them fit better. If the pipe was cut too short, re-cut another pipe to the proper length. CAUTION Do not apply Teflon tape to cover or overlap the pipe opening, as the pipe and nozzles could become blocked and prevent the proper flow of agent. Do not use thread sealant or pipe joint compound. All piping shall be securely fastened by means of pipe hang- ers and/or pipe straps. The spacing requirements for hang- ers/straps depend on the pipe size being utilized. Refer to the Spacing Guidelines Chart below. Pipe Hanger Spacing Guidelines Distribution Maximum Spacing Distance Pipe Size Hanger to Hanger in. ft. (m) 1/4 4 (1.2) 3/8 5 (1.5) 1/2 6 (1.8) 3/4 8 (2.4) A union should be installed in the discharge piping, as close to the cylinder valve as possible, to permit disconnection and removal for inspection and service. Dry air or nitrogen should be blown through the discharge piping to remove chips and other debris prior to installation of nozzles.. Nozzles shall be installed in accordance with the limitations described in Chapter Ill of this manual. Blow-off caps are provided for each nozzle. These will prevent dirt and grease from clogging the nozzle. SYSTEM CHECKOUT AFTER INSTALLATION 1. Model MCH3/NMCH3 Mechanical Control Head Before putting the system into service, all components must be checked for proper operation. During this checkout, assure that the carbon dioxide pilot cartridge is not installed in the control head actuator. Remove the pull pin from the hole in the slide plate. - To check satisfactory operation of the control head, cut the terminal link or the "5" hook holding the link. This will relieve all tension on the fusible link line and operate the b. control head. The slide plate will move fully to the right. The gas valve cable will be released, causg the gas valve to close. Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the Micro Switch in o. the control head will operate. If any of these events fail to occur, the problem must be investigated and repaired. ULEX 3830 PN551274(2) April 1, 2004 Chapter 4 - System Installation Page 4-14 REV. 3 Repair the terminal link and put the fusible link line back into the set position. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate makes contact with the top of the control head box. Once the fusible link line is set (note: Refer to page 4-4 through 4-6 for fusible link installation details), the control head can be placed in the set position. To set the control head, the slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked position. Assure that the gas valve is fully open by ratcheting the gas valve ratchet wheel. CAUTION Before screwing the 16 gram carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring or teflon washer installed. Using a felt-tipped marker, write the date of installation on the carbon dioxide pilot cartridge. Screw the cartridge into the control head actuator until hand-tight.

See Remote Pull Station Installation Section of this chapter for remote pull station installation guidelines. ULEX 3830 August 1, 2005 PN551274(3) Gas Shut-off Valve Installation The Model EN-MCU3 can be used to operate a mechanical gas shut-off valve. This valve is located in the fuel gas supply line to the cooking appliance(s). The valve body has an arrow which indicates direction of gas flow through the valve. The gas shut-off valve is spring loaded and requires five pounds of force to hold it open. This force is supplied by a 1/16 in. diameter stainless steel cable that is connected to the Model EN-MCU3. See "Gas Shut-off Valve Installation" (page 4-11) section of this chapter for gas valve shut-off installation guidelines. After the valve is installed in the gas line, 1/2 in. conduit must be run from the top center knockout of the gas valve box to the top or bottom knockout in the enclosure. See Figure 4-25. A PYRO-CHEM KITCHEN KNIGHT II corner pulley is used wherever a change in conduit direction is required. Remove the gas valve cover and thread the stainless steel cable through the conduit back to the Model EN-MCU3. If the cable enters the enclosure through the bottom knockout, the cable must be run over the gas valve line pulley (see Figure 4-27). If the cable enters the enclosure through the top knockout, the cable must be run under the gas valve line pulley (see Figure 4-28). Thread the cable through the hole in the gas valve ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. CAUTION The gas valve cable must always utilize the gas valve pulley and exit the top or bottom of the enclosure. The gas valve cable cannot exit the side of the enclosure. At the gas valve, loop the cable through the valve stem and secure it with the crimp provided (see Figure 4-18, page 4-11). The gas valve line can now be put into a set position by applying tension to the gas valve line. This is accomplished by using a 1/2 in. hex wrench on the gas valve ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the gas valve is fully open. Secure the gas valve cover plate to the gas valve box with the four (4) screws provided. The gas valve line is now in a set position. See Figure 4-27 and/or Figure 4-28. CAUTION Do not overtighten gas valve.

During this checkout, assure that the carbon dioxide pilot cartridge is not installed in the Model EN-MCU3 actuator. Remove the pull pin from the hole in the slide plate. To check satisfactory operation of the control mechanism, cut the terminal link or the "S" hook holding the link. This will relieve all tension on the fusible link line and operate the control mechanism. The slide plate will move fully to the right. The gas valve cable will be released, causing the gas valve to close. Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the Micro Switch in the Model EN-MCU3 will operate. If any of these events fail to occur, the problem must be investigated and repaired. Repair the terminal link and put the fusible link line back into the set position. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate is parallel to the top of the enclosure. Once the fusible link line is set, the control mechanism can be placed in the set position. To set the control mechanism, the slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked position. Once the control mechanism is set, pull the pull handle on the remote pull station to assure that the control head operates. If the control mechanism operates normally, the control mecha- nism can be reset as described above. Insert the pull pin into the hole in the slide plate above the latching arm. Replace the pull station handle, pull pin, and nylon tie. To test the thermal detectors, use a heat gun. Hold the gun approximately 12 in. (30.5 cm) from the detector for about one minute. Do not overheat. Overheating can cause damage to detector. Allow detector to cool after testing. Assure that the gas valve is fully open by ratcheting the gas valve ratchet wheel. Do not overtighten. CAUTION Before screwing the 16 gram carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring or teflon washer installed. Using a felt-tipped marker, write the date of installation on the carbon dioxide pilot cartridge. Screw the cartridge into the Model EN-MCU3 actuator until hand-tight.

ULEX 3830 August 1, 2005 PN551274(3) Chapter 5 - System Maintenance Page 5-1 REV. 3 CHAPTER V SYSTEM MAINTENANCE / GENERAL This chapter will detail the basic information necessary for proper maintenance of the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. Maintenance must be performed in accordance with NFPA 17A Standard on Wet Chemical Extinguishing Systems and NFPA 96 Standard for the Installation of Equipment for the Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment. However, before attempting any system mainte- nance, it is necessary to attend a Factory Certification Training Class and become certified to install and maintain the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. SEMI-ANNUAL MAINTENANCE Check that the hazard area has not changed. Check that the system has not been tampered with, i.e., nozzles removed, nozzles not aimed properly, piping not supported properly, blow off caps in place. Check the entire system for mechanical damage. Check all nozzle orifices to make certain they are not plugged. Replace blow off caps or 0-ring if necessary. Check the solenoid monitor. CAUTION Before continuing, remove the cover from the control head and insert the safety pin in the hole in the slide plate above the latching arm. This will secure the system, preventing accidental discharge. Disconnect the control head or pneumatic tubing from the valve cap assembly of each agent cylinder. Remove the carbon dioxide pilot cartridge in the control head. Remove the safety pin from the slide plate. Actuate the control head to ensure it is functioning properly. Make certain the gas shut-off valve and remote pull station are functioning properly. NOTE Methods and frequency of inspection, testing and maintenance of detectors should be in accordance with NFPA-72. Reinstall the carbon dioxide pilot cartridge, reconnect the control head, and replace the control head cover and nylon tie. CAUTION Before screwing the carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring installed. Inspect the cylinder pressure. Tap the gauge lightly to ensure the needle is moving freely. If the gauge shows a loss in pressure indicated by the needle being below the green band, the tank should be removed and recharged per the SYSTEM RECHARGE section of Chapter VI (System Recharge) in this manual. ANNUAL MAINTENANCE Inspect as per semi-annual maintenance instructions. Do not reconnect control head at this time. Disconnect the discharge piping from the valve outlet. tJsing air or nitrogen, blow out the piping. Replace all nozzle caps. Fixed temperature sensing elements of the fuxible alloy type must be replaced, at a maximum, annually. It is recommended that they be replaced semi-annually, or more frequently, if necessary, to assure proper operation of the system. Test thermal detectors and remote pull stations per SYSTEM CHECKOUT AFTER INSTALLATION section located in Chapter IV (System Installation) of this manual. Per NFPA 72, two (2) or more detectors per circuit should be tested. Note individual detector location and date of testing. Within 5 years, all detectors in system must be tested. 7.

The tank should be refilled with fresh agent. ULEX 3830 April 1, 2004 PN551274(2) Chapter 6 - System Recharge Page 6-1 REV. 3 CHAPTER VI SYSTEM RECHARGE GENERAL This chapter will detail the basic information necessary for proper recharge of the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. However, before attempting any system recharge, it is necessary to attend a Factory Certification Training Class and become certified to install, maintain, and recharge the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. SYSTEM CLEANUP CAUTION Before attempting any cleanup, make certain that all fuel sources to the equipment to be cleaned have been shut off. Make certain that the exhaust hood and all appliance electrical controls have been de-ener- gized to avoid any chance of electrical shock resulting from the cleaning process of electrically conductive alkaline liquid agent and/or its residue. Make certain all surfaces to be cleaned have cooled down to room temperature. Do not use water to clean any appliances that contain hot grease or cooking oils. Doing so may result in violent steaming and/or spattering. SYSTEM RECHARGE NOTE Determine the cause of system discharge and correct immediately before performing system recharge. j After discharge, inspect the entire system for mechanical damage. If the tank has sustained any mechanical damage, it must be hydrostatically tested before refilling. Disconnect the 1/4 in. actuation tubing or the control head from the top of the tank valve. Relieve the pressure from the top chamber of the tank valve by depressing the core of the valve in the valve cap assembly. By performing this operation, the valve will close. 4. Slowly remove the valve and siphon tube. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. 5. The complete piping system must be flushed after a discharge. Flushing concentrate, Part No. 79656, must be used when flushing the system. The concentrate is shipped in a 32 oz. (.95 L) container. A PCL-160 tank requires 1/2 of a container. A PCL-300 tank requires 1 container of concentrate. A PCL-460 requires 1 1/2 containers, and a PCL-600 requires 2 containers. To prepare the system for flushing: Pour the required amount of flushing concentrate into the tank. Fill the tank approximately half full with warm, clear - water. Agitate the tank for a few seconds and then add more warm water to bring the level to the required fill line using the measuring stick, Part No. 551039. Reinstall valve and pickup tube. Hand tighten to 12.5 foot pounds maximum torque. CAUTION Do NOT use a wrench or other tool to tighten the valve. Do NOT use a pipe extension on the valve outlet for the purpose of providing additional torque. Pressurize tank to 225 psi (15.5 bar) at 70 °F (21 °C) and reinstall to piping network. 6. With nozzles in place, attach control head and manually actuate the tank. Allow the tank to completely discharge through the piping network. 7. After the discharge is completed, the entire piping network must be blown out with air or nitrogen until no more mist is visual coming out of the nozzles. 8. Remove, clean, and reinstall all nozzles. 9. Remove the tank from the system. Slowly remove the valve and siphon. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. The valve and pressure regulator (located in outlet of valve) must be cleaned and rebuilt after each discharge. To rebuild the valve, use rebuilding kit, Part No. 550698. To rebuild the pressure regulator, use rebuilding kit, Part No. 551061. Each kit includes an instruction sheet listing detailed rebuilding instructions. 10. Fill tank with required amount of KITCHEN KNIGHT agent, Part No. 551188 (3 gal.) or Part No. 553176 (1.6 gal.), using measuring stick, Part No. 551039. Tank should be filled to a tolerance of —01+1/8 in. (-0/+.3 cm) from the mark level on the measuring stick. IJLEX 3830 PN551274(3) August 1, 2005 Chapter 6 - System Recharge Page 6-2 REV. 2 NOTE During filling, the agent temperature should be 60 °F to 80 °F (16 °C to 27 °C). NOTE The pressure gauge attached to the tank valve should not be used to determine when the charging pressure has been reached. A calibrated external gauge must be used. NOTE The pressure regulator in the valve outlet must be removed before pressurizing. Reinstall valve and pickup tube. Hand tighten to 12.5 foot pounds maximum torque. Pressurize Shrader valve assembly with 150 psi (10.3 bar) of nitrogen. Install recharge adaptor, Part No. 551240, into the valve outlet and pressurize with nitrogen to 225 psi (15.5 bar) at 70 °F (21 °C). Wait 10 minutes and verify the pres- sure in the tank is at 225 psi (15.5 bar). Relieve the pressure from the Shrader valve assembly (this will cause the valve to close) and then disconnect the recharge adaptor. Reinstall pressure regulator into valve outlet. CAUTION If pressure is not relieved from Shrader valve assem- bly before the recharge adaptor is removed, the tank will discharge. Replace all fusible links by following the instructions listed in the Installation Section. Reset control head(s), accessories, pull stations and gas valves by following the instructions listed in the Installation Section.

However, before attempting any installation, it is necessary to attend a Factory Certification Training Class and become Certified to design the Pyro- Chem Kitchen Knight II Restaurant Fire Suppression System. The chapter is divided into three (3) sections: Nozzle Coverage and Placement Piping Limitations Detector Requirements Each of these sections must be completed before attempting any installation. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appli- ance protection. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. Each nozzle is approved to protect exhaust ducts of unlimited length. Duct protection requires that a nozzle be positioned to discharge into the duct. The nozzle is a Model 2D, Part No. 551038. The Model 2D duct nozzle is a two (2) flow rLozzle.A single 1.20 nozzle is capable of protecting square or rectangular 'ducts with a, maximum perimeter of 100 in.L(254 cm), with the longest side being a maximum of 34 in. (86.4 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). Two (2) Model 2D duct nozzles can protect a square or rectangular duct with a maximum of 150 in. (381 cm) perimeter, with the longest side being a maximum of 51 in. (129.5 cm). They can also protect a round duct with a maxi- mum diameter of 47 1/2 in. (120.7 cm). When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening.

Pyro-Chem Kitchen Knight II recommends that transition ducts be protected as follows: Transition ducts - larger to smaller In cases where the duct/plenum interface opening is larger than the final exhaust duct, measure the perime- ter/diameter of the duct halfway between the largest and smallest section (or the average perimeter/diame- ter). The nozzle is to be located within 0-6 in. (15.2 cm) of the duct/plenum interface (not at the point where the measurement was taken), centered under the final exhaust duct opening. See Figure 3-Ic. PERIMETER —/- — — — MEASUREMENT / 006173PC Figure 3-Ic. Transition ducts - smaller to larger In cases where the duct/plenum interface opening is smaller than the final exhaust duct, measure the perimeter/diameter of the final exhaust duct. The nozzle(s) is to be located within 0-6 in. (15.2 cm) of the duct/plenum interlace, centered in the opening. See Figure 3-Id. PERIMETER MEASUREMENT 006I74PC Figure 3-Id Multiple risers In cases of multiple rises, each riser is protected as an individual duct. See Figure 3-1e. Figure 3-le Electrostatic Precipitator - Ducts utilizing electrostatic precipitators must be protected above and below the unit. Standard duct nozzles are used in this application. See Figure 3-If. 2D NOZZLE PRECIPITATOR PLENUM 2D NOZZLE 006l76PC Figure 3-If Plenum Protection / The Model 1H nozzle, Part No. 551029, is a one (1) flow nozzle used for plenum protection. A single 1 H nozzle can protect a plenum (with single or V-bank filters) 10 ft (3.1 m) l long by 4 ft. (1.2 m) wide.Wividing the length into sections' equal to or less than 10 ft. (3.1 m) in length and positioning a nozzle at the start of each section can be done to protect longer plenums.
