Installation & Operation Manual
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 large
flat-bladed screwdriver
, thread the impeller
onto the motor shaft. Hand-tighten the
impeller until it is secure.
Do not overtighten.
3.
Install the impeller sleeve on the impeller.
4.
Place 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.
5.
Replace the two (2) small Phillips-head
screws. Tighten the screws to draw the
diffuser against the motor backplate.
6.
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.
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 13 Nm.
9.
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.
10. To help prevent an air leak into the system,
remove any debris around the lid seal seat.
11.
Hand-tighten
the lid to make an air tight seal.
Do not use any tools to tighten the lid.

2. Open the pressure release valve on the filter
and make sure it is clean and ready for
operation.
13. Switch on the circuit breaker to the pump
motor.
14. Turn on the pump and check the system for
normal operation.
15. 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.
NOTE
Refer to Figure 19 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.

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.)
