Installing the Pump
Only a qualified service person should install the pump. Refer to “IMPORTANT SAFETY
PRECAUTIONS” on pages iii tfo vi for additional installation guidance.
Location
1. Install the pump as close to the pool or spa as possible. To reduce friction loss and improve
efficiency, use short and direct suction and piping returns.
2. Install a minimum of five (5) feet (1.5 meters) from the inside wall of the pool and spa. Canadian
installations require a minimum of three (3) meters (9.8 feet) from pool water.
3. Install the pump a minimum of two (2) feet (0.6 meters) from the heater outlet.
4. Do not install the pump more than (8) feet (2.4 meters) above the water level or three (3) feet (0.9
meters) below water level.
5. Install the pump in a well ventilated location protected from excessive moisture, (i.e., rain gutter
downspouts, sprinklers, etc.).
6. For hot tubs and spas, do not install within an outer enclosure or beneath the skirt of a hot tub or spa.
7. Install the pump with a rear clearance of at least 6 inches (15.2 centimeters) so that the motor can be
removed easily for maintenance and repair.
Piping
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.
Do not install 90° elbows directly into pump inlet or outlet. 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 (i.e., two (2) inch pipe requires a ten (10) inch (25.4 centimeters) straight run in front of the
suction inlet of the pump). This will help the pump prime faster and last longer.
Flooded suction systems should have gate valves installed on suction and discharge pipes for
maintenance, however, the suction gate valve should be no closer than five (5) times the suction pipe
diameter as described above.
Check Valve
Suction check valves and hydrostatic valves must not be installed with this pump. Also, IntelliFlo
pumps cannot be used in series with other pumps.
When check valves are installed on the discharge side of the pump a SVRS Check Valve Kit,
part number 350250Z, must be installed.
