6.2.4 Mechanical Seal Replacement
NOTE
This is a two-part replacement process.
The
mechanical seal must be replaced as a set.
NOTE
Refer to Figure 9 for the location of the mechanical
seal and impeller.
WARNING
Do not damage the ceramic or carbon surfaces of the
seals. If surfaces are damaged, leaks will occur.
1.
To access the mechanical seal, comply with the
warning and follow steps 1 through 8 of Section
6.2.2, Impeller Removal.
2.
Remove the carbon face seal half from the
motor shaft, see Figure 8. This is a spring-loaded
seal. Grasp the portion of the seal closest to
the impeller body and pull the seal off using a
twisting motion.
3.
Remove the motor from the backplate by
complying with the caution and following steps 1
through 3 in Section 6.2.5.
4.
Place the backplate o-ring side down and force
the ceramic seal out using a screwdriver or drift.
5.
Turn the backplate o-ring side up and insert the
new ceramic seal side into the backplate. Use
great care to press the seal in squarely with your
fingers. The ceramic is easily damaged and must
be pressed in using only your fingers or soft
tools. Do not use any lubricant other than water
and soap solution.
6.
Install the motor by complying with the caution
and following the steps in Section 6.2.5, Motor
Replacement.
7.
Install the backplate by complying with the
caution and following the steps in Section 6.2.3,

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

Have a qualified service technician or electrician
properly disconnect the electrical wiring at the

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.
