Installing the IntelliFlo
Only a qualified service person should install the IntelliFlo pump.
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 from the inside wall of the pool and spa. Canadian installations require
a minimum of three (3) meters from pool water.
3. Install the pump a minimum of two (2) feet from the heater outlet.
4. Do not install the pump more than (8) feet above the water level.
5. Install the pump in a sheltered well ventilated location protected from excessive moisture, (i.e., rain,
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 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 use Teflon
® tape.
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 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
Check valves must be used when the IntelliFlo is used in parallel with other pumps. IntelliFlo pumps cannot
be used in series with other pumps.
