Installation Guide: IntelliFlo3 and IntelliPro3 vsf pool Pump

Plumbing and Fittings
1. Provided union kit allows for easy plumbing to 
a variety of pipe diameters. See 
UNION KIT 
OPTIONS
.
2. For improved plumbing a larger pipe size should be 
used.
3. 
To reduce friction loss and improve efficiency, short 
and direct suction and return lines are best.
4. Suction line diameter should be the same or larger 
than the return line diameter. 
5. Do not install 90° elbows directly into the pump inlet 
or outlet. 
6. Valves, elbows or tees installed in the suction line 
should be no less 
than five times the suction pipe 
diameter from the pump inlet.
Example:
 
A 2-inch pipe requires a 10-inch (25.4 
cm) straight run from the suction inlet. This will 
help the pump prime faster and last longer.
Valves
1. Flooded suction systems should have valves installed 
in both the pump suction and return lines. This allows 
the pump to be isolated during routine maintenance.
2. Install a check valve in the return line when using this 
pump for any application where there is significant 
height to the plumbing after the pump.
3. Install check valves when plumbing in parallel with 
another pump. This helps prevent reverse rotation of 
the impeller and motor.
