DELIVERY AND INSTALLATION
All valves and appurtenances shall be installed per these Specifications, the
manufacturer's instructions and approved shop drawings in the locations shown, true to
alignment and rigidly supported. Any damage to the above items shall be repaired to
the satisfaction of the Engineer before they are installed.
Install all brackets, extension rods, guides, the various types of operators and
appurtenances as required. Before setting these items, the MFEM shall check all
Drawings and figures which have a direct bearing on their location. The MFEM shall
be responsible for the proper location of valves and appurtenances during the
fabrication of all MFEM supplied items on which valves are installed.
All materials shall be carefully inspected for defects in construction and materials. All
debris and foreign material shall be cleaned out of openings, etc. All valve flange
covers shall remain in place until connected piping is in place. All operating
mechanisms shall be operated to check their proper functioning and all nuts and bolts
checked for tightness. Valves and other equipment which do not operate easily, or are
otherwise defective, shall be repaired or replaced at no additional cost to the District.
Unless otherwise noted, joints for valves and appurtenances shall be made up utilizing
the same procedures as specified under the applicable type connecting pipe joint and all
valves and other items shall be installed in the proper position as recommended by the
manufacturer. The MFEM shall be responsible for verifying manufacturers' torque
requirements for all valves.
In horizontal pipe runs centered less that 4'4" above the operating floor, orient valve
stems as close to vertical as permitted by adjacent piping.

The Installation Contractor will install all loose shipped valves provided by the MFEM.
COMMISSIONING
See also Division 1. Take care not to over pressure valves or appurtenances during
pipe testing. If any unit proves to be defective, it shall be replaced or repaired to the
satisfaction of the Engineer.
No testing shall be performed until the manufacturer’s service engineer has provided
written certification that the installed equipment has been examined and found to be in
complete accordance with the manufacturer’s requirements.
Functional Test: Prior to plant startup, all items shall be inspected for proper
