6 PUMP INSTALLATION
6.1 Pum p Location
Locate pump as close to the water source as practical. For swimming pools, consult local codes for
minimum distance between pool and pump. Place the pump on a solid foundation to provide a rigid and
vibration-free support. Leave access space around it to allow room for service and maintenance.
Whenever possible, the pump should be below the water level in the source, to ensure quick priming via
a flooded suction line. This is normal for swimming pool applications. If this is not possible, see Section
5.3 Suction Applications.
Protect the pump against flooding and excess moisture. Prevent foreign materials from blocking air
circulation around the motor.
DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this pump. DO NOT
store pool chemicals near the pump.
6.2 Piping
WARNING The pump has quick-disconnect unions made of ABS plastic. Use only an approved
type of solvent cement to connect pipes to these unions.
To connect ABS pipe to the pump unions, use cement that is approved for ABS pipe. To connect PVC
pipe to the pump unions, use cement that is approved for connection of BOTH materials. It is called
ABS/PVC crossover cement
.
If the suction pipe is not sealed perfectly, air will be drawn in. The pump will not prime properly and will
perform poorly.
The piping should be as direct and free from turns or bends as possible, as elbows and other fittings
greatly increase friction losses. Avoid sharp 90° elbows. Use sweep elbows or dual 45° elbows instead.
Pipes should never be smaller than the fittings on the pump. Long distances may require larger pipe.
Consult a pipe sizing chart to calculate the equivalent head loss. This is especially critical when using a
solar pump, as we are trying to get the most flow for the least amount of power. Reducing the
performance of the system by using small-sized pipe is false economy.
Suction and discharge line should be independently supported at a point near the pump to avoid excess
strain on the pump.
It is advisable to install gate valves in both the suction and discharge line in the event that the pump must
be removed for service.
