Whisperflo
High Performance Swimming Pool Pump
We call it WhisperFlo® for good reason. This innovative
hydraulic design moves water more efficiently and more
quietly than competitive pumps. Under typical operating
conditions, WhisperFlo offers the highest water flow
of any high performance pump – yet with the lowest
electrical consumption. And, WhisperFlo is designed
to be a tireless workhorse. Its engineered thermoplastic
housing withstands extreme heat and resists corrosion.
The commercial grade motor frame has a rust-proof,
stainless steel motor shaft and sealed bearings that never
need lubrication. Engineered to provide optimum
performance in any size pool or pool and spa combination,
WhisperFlo is built to last a lifetime, and, as a result,
has become the industry’s top seller for years.
GENERAL INFORMATION
Wiring:
1. Make sure all electrical breakers and switches are turned off before wiring motor.
2. Make sure that the wiring voltage matches the motor voltage (230v or 1 15v). If they do not match the motor will burn up.
3. Choose a wire size from the Chart 1. When in doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the motor to run cooler and more efficient.
4. Make sure all electrical connections are clean and tight.
5. Cut wires to the appropriate length so they don’t overlap or touch when connected to the terminal board.
Permanently ground the motor using the green ground terminal located on the inside of the motor canopy or access plate, see Figure 1. Use the correct wire size and type specified by National Electrical Code. Make sure the ground wire is connected to an electrical service ground.
7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid No. 8 AWG or larger copper conductor. Run a wire from the external bonding to the pool bonding structure, see Figure 1.
8. Connect the pump permanently to a circuit. Make sure no other lights or appliances are on the same circuit.
The Pump Strainer Basket.
This unit, sometimes referred to as the ‘Hair and Lint Pot’, is the unit in front of the volute. Inside the chamber is the basket which must be kept clean of leaves and debris at all times. View basket through the ‘See Through Lid’to inspect for leaves and debris.
Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint pot basket at least once a week. A dirty basket will reduce the efficiency of the filter and heater and also put an abnormal stress on the pump motor which would result in a costly repair bill.
MAINTENANCE
Pump Strainer Basket Cleaning Procedures.
1. Turn off motor.
2. Relieve pressure in the system.
3. Turn the clamp and lid in a counter-clockwise direction until it stops.
4. Turn the clamp and lid set to remove the clamp and lid.
5. Put the debris from the basket into the trash and rinse out the basket. If the basket is cracked, it should be replaced.
6. Replace the basket and fill the pump pot and volute up to the inlet port with water.
7. Clean the cover, cover O-ring, and sealing surface of the pump pot. Grease the O-ring with Teflon or silicone.
8. Reinstall the lid by placing the clamp and the lid on the pot; see Figure 2.
a. Make sure the lid O-ring is properly placed. Seat the clamp and lid
then turn clockwise until the handles are horizontal; see Figure 3.
9. Turn the power “ON” at the house circuit breaker. Reset the pool time clock to the correct time.
10. Open the High Flow™ manual air relief valve on top of the filter.
11. Stand clear of the filter. Start the pump.
12. Bleed air from the filter until a steady stream of water comes out. Close the High Flow™ manual air relief valve.
Winterizing
1. If the air temperature drops below 35° F. the water in the pump can freeze and cause damage. Freeze damage is not warrantable.
2. To prevent freeze damage follow the procedures listed below.
a. Shut off electrical power for the pump at the house circuit breaker.
b. Drain the water out of the pump case by removing the two thumb
twist drain plugs from the case. Store the plugs in the pump
basket.
c. Cover the motor to protect it from severe rain, snow and ice.
d. Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the motor.
Care of Electric Motor
1. Protect from heat.
a. Shade the motor from the sun.
b. Any enclosure must be well ventilated to prevent overheating.
c. Provide ample cross ventilation.
2. Protect against dirt.
a. Protect from any foreign matter or splashing water.
b. Do not store (or spill) pool chemicals near the motor.
c. Avoid sweeping or stirring up dust near the motor while it is operating.
d. If a motor has been damaged by dirt it voids the motor warranty.
3. Protect against moisture.
a. Protect from splashing pool water.
b. Protect from the weather.
c. Protect from lawn sprinklers.
d. If a motor has become wet - let it dry before operating. Do not allow the pump to operate if it has been flooded.
e. If a motor has been damaged by water it voids the motor warranty.
Priming the Pump
1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to prime the pump.
a. Remove the pump lid plastic clamp. Remove the pump lid.
b. Fill the pump strainer pot with water.
c. Reassemble the pump cover and plastic clamp onto the strainer pot. The pump is now ready to prime.
d. Open the air release valve on the filter, and stand clear of the filter.
e. Turn on the switch or time clock.
f. When water comes out of the air release valve, close the valve. The system should now be free of air and recirculating water to and from the pool.
2. For 2-speed pumps:
a. Pump should run on high-speed for priming.
b. The pump should not run longer than 8 minutes before priming is achieved.
Troubleshooting
Pump Will Not Prime - to much air
Check suction piping and valve glands on any suction gate valves.
Secure lid on pump strainer pot and make sure lid gasket is in place.
Check water level to make sure skimmer is not drawing air.
Pump Will Not Prime - not enough water/ Pump strainer clogged
Make sure suction lines, pump strainer, and pump volute are full of water.
Make sure valve on suction line is working and open, (some systems do not have valves).
Check water level to make sure water is available through skimmer.
Clean pumpstrainerpot.
Pump strainer gasket defective
Replace gasket.
REDUCED CAPACITY and or HEAD Air pockets or leaks in suction line Pump Will Not Prime - to much air
Checksuction piping and valve glands on any suction gate valves.
Secure lid on pump strainer pot and make sure lid gasket is in place.
Check water level to make sure skimmer is not drawing air.
Clogged impeller
Turn off electrical powerto the pump.
Remove the clamp that holds the volute to the seal plate.
Slide the motor and seal plate away from the volute.
Clean debris from impeller.
If debris cannot be removed, complete the following steps.
(1) Remove left hand thread anti-spin bolt and 0-ring.
(2) Remove, clean and reinstall impeller.
(3) Reinstall anti-spin bolt.
Reinstall diffuserand quad ring.
Reinstall motor and seal plate into volute.
Reinstall clamp around seal plate and volute and tighten securely.
Pump strainer clogged
Clean suction trap.
