Installation & Operation Manual
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, see Section
6.2.2, Impeller Removal and Replacement.
2.
Remove the carbon face seal half from the
motor 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
IMPORTANT
This pump must be installed with a two-, multi-, or
variable-speed pump motor controller.
WARNING
To ensure continued safety and reliable operation,
Zodiac
®
requires that you replace the motor with a
motor that has the identical HP rating and service
factor (Zodiac Pool Systems, Inc. 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 all switches and the main breaker in the
VS-FHP 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.
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.
5.
Replace the four (4) bolts and washers holding
the backplate to the motor and torque to 15 foot-
pounds. 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.
