Installation

Only a qualifi ed service person should install IntelliFloXF
"Pump Warning And Safety Instructions" on pages ii to vi for additional installation and safety
information.

Location

Be sure the pump location meets the following requirements:
Pump inlet as close as possible to water level.
•
Short, direct suction piping returns (reduces friction loss).
•
Install pump in a sheltered, well ventilated area to protect from excess moisture (i.e.,
•
rain, sprinklers, etc.) and fl ooding.
Install and secure pump on level concrete slab or fi rm surface (reduce vibration noise).
•
Pump location should allow access for servicing and maintenance.
•
Pump Location Installation Guide:
From Heater Outlet
Above water level
Below water level
From inside wall of pool
Rear clearance of pump
Hot tubs and Spas
*Minimum of 9.8 feet (3 m) for Canadian installations.
Piping
Use larger pipe sizes for improved pool plumbing. Suction pipe diameter should be the same
as or larger than the return line diameter.
Install piping as close to the water level as possible.
•
• On the equipment pad, run straight, horizontal piping into the suction side of the pump.
For best performance, the length of the piping should be equal to fi ve (5) pipe diameters.
For example, if pool is plumbed with 3 in. diameter PVC pipe, then a straight section of
pipe 15 in. long should be used for the suction side of the pump.
Fittings
• Install fi ttings (valves, elbows, tees, etc.) in the suction
line no closer than fi ve (5) times the pipe diameter to
the front of the pump (eg. 3" pipe = 15 in).
Do not install 90° elbows directly into pump inlet.
•
Valves
Install valves on suction and discharge pipes for maintenance of fl ooded suction systems-
•
install no closer than fi ve (5) times the suction pipe diameter.
Use a check valve in the discharge line when using this pump for waterfalls, solar heating
•
systems, or in any application where there is signifi cant height to the plumbing after the pump.
Be sure to install check valves when plumbing in parallel with another pump. This helps
•
prevent reverse rotation of the impeller and motor.
