6. Install the pump with a rear clearance of at least 3 inches (76.2mm) so that the motor can be
removed easily for maintenance and repair. See
Figure 1
.
Piping
1. For improved pool plumbing, it is recommended to use a larger pipe size. When installing
the inlet and outlet fittings (male adaptors), use thread sealant.
2. Piping on the suction side of the pump should be the same or larger than the return line
diameter.
3. Plumbing on the suction side of the pump should be as short as possible.
4. It is recommended that a valve, elbow or tee installed in the suction line should be no closer
to the front of the pump than five (5) times the suction line pipe diameter. See Figure 2.
Example:
A 2 inch pipe requires a 10 inch (254 mm) straight run in front of the suction inlet of the pump.
This will help the pump prime faster and last longer
Fittings and Valves
1. Do not install 90
°
elbows directly into pump inlet.
2. Flooded suction systems should have gate valves installed on suction charge pipes for
maintenance, however, the suction gate valve should be no closer than five times the suction
pipe diameter as described in this section.
3. Use a check valve in the discharge line when using this ump for any application where there
is significant eight to the plumbing after the pump.
4. Be sure to install check valves when plumbing in parallel with another pump. This helps
