impeller.
6.2.2 Impeller Removal
WARNING
While 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 5.
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 6). The SHPF 5.0 uses a
different diffuser than other models (See Figure 8).
NOTE At this point you have access to the inlet and
outlet of the impeller to remove any debris.
