Installation & Operation Manual
CAUTION
Very Important!
To prevent damage to the seal,
grasp the lower portion of the seal (opposite the
carbon face) when installing it.
NOTE
To assist assembly, use only water or soapy water as
a lubricant. Any other lubricant will destroy the seal
after a short period of time.
NOTE
Be sure to keep the seal and mating parts clean.
2.
While holding the motor shaft with a ¼” hex
allen wrench, thread the impeller onto the
motor shaft. Hand-tighten the impeller until it is
secure.
Do not overtighten.
3.
Insert and turn the left-hand-threaded impeller
screw counter-clockwise to tighten it.
4.
Replace the fan cover by replacing the screws.
5.
Replace the diffuser over the impeller, using
care to insert alignment pins into the correct
holes. The molded-in arrow must point toward
the handle of the backplate.
6.
Replace the two (2) small Phillips-head screws.
Tighten the screws to draw the diffuser against
the motor backplate.
7.
To help prevent an airleak into the system, make
sure the
diffuser
o-ring, o-ring groove, and
o-ring seal area are clean and free of debris. If
you removed the diffuser o-ring, m
ake sure you
install it into the groove you removed it from.
(See Figure 18.)
If grease is used to retain the
o-ring, it
must
be silicone based.
Do not use
petroleum-based grease
. It will destroy the
o-ring.
8.
Slide the diffuser into the mating hole in the
pump body. While supporting the motor, start
two (2) screws on opposite sides. (This will hold
the motor in position while you start the other
six (6) screws.)
9.
Tighten the screws lightly in a crossing “X”
pattern using a 9/16” wrench. Start with the
inner (middle) four (4), then the outer (top and
bottom) four (4) to draw the backplate to the
body in an even manner. Once all the screws
are snug, torque in the same order to 10 foot-
pounds.
10. 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.
11. To help prevent an air leak into the system,
remove any debris around the lid seal seat.
12.
Hand-tighten
the lid to make an air tight seal.
Do not use any tools to tighten the lid.
13. Open the pressure release valve on the filter and
make sure it is clean and ready for operation.
14. Switch on the circuit breaker to the pump motor.
15. Turn on the pump and check the system for
normal operation.
16. Once all the air has left the filter, close the
pressure release valve.
6.3.3 Mechanical Seal Replacement
NOTE
This is a two-part replacement process.
The
mechanical seal must be replaced as a set.
