CAUTION
To ensure continued safety and reliable operation,
Zodiac Pool Systems, Inc. requires that you replace
the motor with a motor that has the identical HP
rating and service factor (Zodiac Pool Systems, Inc.
approved only).
WARNING
To avoid the risk of property damage, severe per-
sonal injury, or death, turn off the pump and switch
off the circuit breaker to the pump motor before
beginning this procedure.
1. Have a qualified service technician or electrician
properly disconnect the electrical wiring at the
pump motor.
2. To disassemble the pump housing from the motor,
follow steps 1 through 8 in Section 6.2.2, Impeller
Removal.
3. Place the backplate motor assembly o-ring side
down and unscrew the four (4) 9/16" screws and
remove the motor.
NOTE Before removing the backplate, note the
alignment of the backplate to the motor. See

4. If installing a new motor, remove the protective
plastic cap from the motor shaft. Place the motor
on the backplate so that the opening in the motor
faces the bottom of the backplate. The starting
capacitor on the motor should be at the
12 o'clock position.
5. Replace the four (4) bolts and washers holding the
backplate to the motor.
6. To reassemble the pump after replacing the
motor, follow steps 1 through 14 of Section 6.2.3,
