Complete operating and maintenance manuals including wiring diagrams, technical data sheets, information for ordering replacement parts, and troubleshooting guide: Include complete list indicating all components of the systems. Include complete diagrams of the internal wiring for each item of equipment. Diagrams shall have their terminals identified to facilitate installation, operation and maintenance. //Completed System Readiness Checklist provided by the CxA and completed by the contractor, signed by a qualified technician and dated on the date of completion, in accordance with the requirements of Section 22 08 00, COMMISSIONING OF PLUMBING SYSTEMS.// //Submit training plans and instructor qualifications in accordance with the requirements of Section 22 08 00, COMMISSIONING OF PLUMBING SYSTEMS.// QUALITY ASSURANCE General: UL Compliance: Comply with UL 778 for motor-operated water pumps. Design Criteria: Pump sizes, capacities, pressures, operating characteristics and efficiency shall be as scheduled. Head capacity curves shall slope up to maximum head at shut off. Select pumps near the midrange of the curve, and near the point of maximum efficiency, without approaching the pump curve end point and possible cavitation and unstable operation. Select pumps for open systems so that required net positive suction head (NPSHR) does not exceed the net positive head available (NPSHA). Pump Driver: Furnish with pump. Size shall be non-overloading at any point on the head capacity curve, including in a parallel or series pumping installation with one pump in operation. Provide all pumps with motors, impellers, drive assemblies, bearings, coupling guard and other accessories specified. Statically and dynamically balance all rotating parts. Furnish each pump and motor with a nameplate giving the manufacturers name, serial number of pump, capacity in GPM and
