Service Technician Maintenance

WARNING
This pump must be serviced by a professional
service technician qualified in pool/spa installation.
The following procedures must be followed exactly.
Improper installation and/or operation can create
dangerous electrical hazards, which can cause
high voltages to run through the electrical system.
This can cause property damage, serious personal
injury, and/or death. Improper installation and/or
operation will void the warranty.

6.2.1 Blocked Impeller

WARNING
Before servicing the pump, switch off the circuit
breakers at the power source. Severe personal
injury or death may occur if the pump starts while
your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker
to the pump motor.
2. Remove the lid and basket.

debris found inside.
4. Replace the basket and lid.
5. Switch on the circuit breaker to the pump motor.

6.2.2 Impeller Removal and Replacement

WARNING
Before servicing the pump, switch off the circuit
breakers at the power source. Severe personal
injury or death may occur if the pump starts while
your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker
to the pump motor. If you are not replacing the
motor, do not disconnect the electrical wiring.
NOTE If you are replacing the motor, Zodiac Pool
Systems, Inc. strongly recommends that a
qualified service technician or electrician
properly disconnect the electrical wiring at the
pump motor.
2. Turn off any valves to prevent pool water from
reaching the pump. Drain the water from the pump
by loosening the unions or removing the
drain plugs.
3. Using a 9/16" wrench, loosen the bolts connecting
the pump body to the motor backplate. See
Figure 9.
4. Pull the motor and backplate out of the pump
body. Remove the pump body o-ring. The impeller
is connected to the motor shaft.
5. Using a No. 1 Phillips screwdriver, remove the
two (2) screws holding the diffuser. (The diffuser
is the cover over the impeller.) Then remove the
diffuser. See Figure 10.
6. Access the inlet and outlet of the impeller and
remove any debris.
7. Remove the fan cover on the back of the motor by
removing the screws. (See Figure 9.) The motor
shaft and fan will be exposed.
8. Hold the exposed motor shaft with a ½" wide flat
blade screw driver while removing the impeller
center screw. Use a No. 3 Phillips screwdriver and
turn the left-hand threaded screw clockwise to
loosen it. See Figure 11.
NOTE Do not hold the fan to remove the impeller
screw.
9. Hold the motor shaft with a ½" wide flat blade
screw driver while unscrewing the impeller from
the motor shaft with your hand. Turn the impeller
counter-clockwise to unscrew it.
10. Inspect the impeller and diffuser for signs of
rubbing and/or damage. Refer to Figure 12.
