6.2.3 Mechanical Seal Replacement

NOTE This is a two-part replacement process. The
mechanical seal must be replaced as a set.
NOTE Refer to Figure 15 for an illustration of the
location of the mechanical seal and impeller.
CAUTION
Do not damage the ceramic or carbon surfaces of the
seals. If the surfaces are damaged, leaks will occur.
1. To access the mechanical seal, follow Steps 1
through 9 of Section 6.2.2, Impeller Removal and
Replacement.
2. Remove the carbon face seal half from the motor
shaft (See Figure 13). 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, following
the steps in Section 6.2.5, Motor Replacement.
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 or soapy
water.
6. Install the backplate by following the relevant
steps in Section 6.2.2.1, Impeller Reassembly.
7. Install the motor by following the steps in
Section 6.2.4, Motor Replacement.

WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Wait five (5) minutes after power is
disconnected before opening motor. On the Jandy

the LED on top of the Drive Electronics Unit is
completely off. Failure to comply may cause a shock
hazard, resulting in severe personal injury or death.
NOTE Zodiac Pool Systems, Inc. recommends that
the mechanical seals be replaced at the same
time the motor is replaced. See Section 6.2.3,
Mechanical Seal Replacement, for details.

as shown in Figure 16. Place the backplate motor
assembly o-ring side down, unscrew the four 9/16"
screws, and remove the motor.
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 electronics
controller on the motor should be at the 12 o'clock
position.
