Pump mount must: Allow pump inlet height to be as close to water level as possible. Allow use of short, direct suction pipe (to reduce friction losses). Allow for gate valves in suction and discharge piping. Be protected from excess moisture and flooding. Allow adequate access for servicing pump and piping.

Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction
loss.
Suction lines should have continuous slope upward from lowest point in line.
Joints must be tight
(but not over-tightened).
Suction line diameter must equal or be larger than the discharge line diameter.
Though the pump is designed for outdoor use, it is strongly advised to place pump and filter in the
shade to shield them from continuous direct heat.
Select a well-drained area that will not flood when it rains.
Do NOT
install pump and filter in a damp or non-ventilated location.

The base must be level, rigid, and vibration free.
Pump mount must:
±
Allow pump inlet height to be as close to water level as possible.

Pipe Sizing Chart
* NOTE -
It is recommended that a minimum length of straight piping (shown as “L” in above diagram), equivalent
to 5 pipe size diameters, be used between the pump suction inlet and any plumbing fittings (elbows, valves, etc.).
