10. Turn on the booster pump and check the system
for proper normal operation.
2. Replace the Impeller and
Mechanical Ceramic/Spring Seal
1.
To access the impeller and mechanical seal, follow
steps 1 though 4 of Section 1.
2.
Remove the motor shaft cover on the back of the
motor by twisting the hex-head motor cover with
an adjustable wrench. See Figure 1. The motor
shaft will be exposed.
3.
The impeller is connected to the motor shaft.
Hold the motor shaft with a ½” wrench while
unscrewing the impeller from the motor shaft with
your hand.
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 removing the drain plug.
3.
Using a 1/2” wrench, loosen the six (6) bolts
connecting the pump volute to the motor
backplate. Remove the bolts and washers and
either set aside to use in reassembly or use new
ones from the kit. See Figure 1.
4.
Pull the volute from the backplate.
NOTE The impeller is a right-handed thread, therefore turn
the impeller counter-clockwise to unscrew.
4.
Inspect the impeller for signs of rubbing and/or
damage and replace if necessary.
5.
If you are replacing the mechanical seal do steps 6
through 10, if not, skip to step 11.
NOTE At this point you have access to the inlet and outlet of
the impeller to remove any debris.
5.
Remove the backplate o-ring and replace it with
the new o-ring making sure it is seated properly.

7±0.3 ft-lbs
Once all the air has left the filter, close the
air release valve. (Follow the manufacturer’s
instructions for your filter.)
CAUTION
Do not damage the ceramic or carbon surfaces of the
seals. If surfaces are damaged, leaks will occur.
6.
Remove the carbon face seal half from the
impeller. Refer to Figure 2 and 3. This is a springloaded seal. Grasp the portion of the seal closest
to the impeller body and pull the seal off using a
twisting motion.
NOTE This is a two (2) part replacement process. The

Pipe dope should NEVER be used on barb threads.
Pipe dope will severely weaken the plastic, causing
leakage and may cause the plastic to fracture. DO
NOT OVERTIGHTEN.
3.
Thread and tighten the tapered thread of the
connector barb into the pump port on the pump
body. See Figure 4 (b).
