Page 6: Uncrating And Inspection
UNCRATING AND INSPECTION Handle with care. Check items received against packing list to be sure that all equipment has been received. Inspect for shipping damage. If found, file claim with carrier immediately. Cleanup Clean up all trash and other materials which will interfere with installation from foundation and surrounding area. - Page 7 Use larger pipe as required to keep water velocity below 7 feet per second or local construction code limits, whichever is lower. Suction pipe must rise continuously from source to pump. To avoid airlock- ing, do not allow high spots in pipe. When using reducer to connect to pump flange, use an eccentric reducer with the straight side on top.
- Page 8 Suction Outlet Covers All suction outlet covers must be maintained. They must be replaced if cracked, broken, or missing. See Page 6 for outlet cover certification requirements. All suction outlets must have correctly installed, screw-fastened covers in place. Outlets Per Pump Provide at least two hydraulically balanced main drains, with covers (see Page 6), for each swimming pool pump suction line.

Page 10: Operation
Start pump; it should prime now. Priming time will depend on vertical length of suction lift (10'/3m maximum) and horizontal length of suction pipe. Priming for the A142C through A145C3 series pumps has been tested to 10 ft. elevation above water level. Priming time using 6” diameter suction pipe is approximately 9 minutes, at less than 1,000 ft. -
Page 11: Service
If pump does not prime, make sure that all valves are open, suction pipe end is under water and that there are no leaks in suction pipe. Fill strainer to bot- tom of inlet port. Make sure that there are no vacuum leaks around drain plugs, gaskets, and O-Rings. - Page 12 20. Install new volute gasket and slide motor/impeller/bracket assembly into place; bolt up to volute. Tighten cap screws and nuts to 450 inch-lbs. (5.2 kg-m) torque. 21. Pumps below water level: Close drains; open system valves to fill pump. Pumps above water level: Fill strainer and prime pump. Open system valve if they were closed at disassembly.
