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 ½" wide flat
blade screw driver, thread the impeller onto the
motor shaft. Hand-tighten the impeller until it is
secure. Install the impeller center screw into the
center of the impeller. Turn the left-hand threaded
screw counter-clockwise and tighten it, using a
No. 3 Phillips screwdriver. Do not overtighten.
3. Replace the fan cover by replacing the screws.
4. Replace the motor shaft cover by inserting the
cover tabs into the slots and rotating the cover 90°
clockwise.
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,
install it into the groove you removed it from. (See
Figure 14.) 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

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 18 foot-pounds.

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.
