The following general information describes how to install the IntelliFlo pump.
Attention Installer: Before installing the IntelliFlo pump, read and follow all warning notices,
instructions and safety precautions on pages 3, 4 and 5.

Installing the IntelliFlo

Only a qualified service person should install the IntelliFlo.

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 1,5 m or 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 60 cm or two (2) feet from the heater inlet.
4. Do not install the pump more than 2,5 m or (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 15 cm or 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 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.,
5 cm or two (2) inch pipe requires a 25 cm or 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 Valves

Check valves must be used when an IntelliFlo is used in parallel with other pumps. IntelliFlo pumps
cannot be connected in series with other pumps.
