Installation & Operation Manual
2.
Remove the carbon face seal half from the
impeller shaft (See Figure 15). 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 6.3.4, 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 6.3.2.1, Impeller Reassembly.
7.
Install the motor by following the steps in
Section 6.3.4, Motor Replacement.
6.3.4 Motor Replacement
WARNING
To ensure continued safety and reliable operation,
Zodiac
®
requires that you replace the motor with a
motor listed in the spares list that has the identical
HP rating and service factor (Zodiac approved
only).
1.
Have a qualified service technician or
electrician properly disconnect the electrical
wiring at the pump motor.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off power to the FloPro pump electrical circuit
before starting the procedure. Wait five (5) minutes
after power is disconnected before opening motor.
Failure to comply may cause a shock hazard,
resulting in severe personal injury or death.
2.
To detach the pump housing from the motor,
see Section 6.3.2, Impeller Removal and
Replacement.
3.
Note the alignment of the backplate to the
motor, as shown in Figure 20. Place the
backplate motor assembly o-ring side down,
unscrew the four 9/16” screws, and remove
the motor.
4.
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.
5.
Replace the four (4) bolts and washers
holding the backplate to the motor and torque
to 20 Nm. See Figure 20.
6.
To reassemble the backplate assembly to
the housing, see Section 6.3.2.1, Impeller
Reassembly.
7.
If the pump is located above the water level
of the pool, remove the lid and fill the basket
with water before starting the pump.
8.
To help prevent an air leak into the system,
remove any debris around the lid seal seat.
9.
Hand-tighten
the lid to make an air tight seal.
Do not use any tools to tighten the lid.
10. Open the pressure release valve on the filter
and make sure it is clean and ready for
operation.
11. Have a qualified service technician or
electrician properly connect the electrical
wiring at the pump motor.
12. Turn on the electrical power to the pump
motor using your controller and check the
system for normal operation.
13. Once all the air has left the filter, close the
pressure relief valve.
NOTE
Zodiac recommends that the mechanical seals be
replaced at the same time the motor is replaced.
See Section 6.3.3, Mechanical Seal Replacement,
