. Slide the diffuser into the mating hole in the pump body to connect the pump body to
the backplate. While supporting the motor, start two (2) screws on opposite sides. (This
will hold the motor in position while you start the other screws.) Start the other four (4)
screws.
8. Tighten all six (6) screws lightly in a crossing “X” pattern using a 14mm wrench. Start
with the inner (middle) two (2), then tighten the outer (top and bottom) four (4) to draw
the backplate to the body in a even manner. Once all the screws are snug, torque in the
same order to 10 foot-pounds.
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. Prior to replacing the lid, remove any debris around the lid o-ring seat, as debris will
allow air to leak into the system.
11. Place the lid with locking ring on the pump housing. Align ‘START’ with the ports and
turn the lid’s locking ring clockwise until ‘LOCKED’ aligns with the ports. Hand-tighten
the lid to make an air tight seal. Do not use any tools to tighten the lid.
12. Switch on the circuit breaker to the pump motor.
13. Turn on the pump and check the system for normal operation.
14. Check for any leakages.
6.2.4 Mechanical Seal Replacement
NOTE: Refer to
Figure 7
for an illustration of the location of the mechanical seal and
impeller.
Figure 7. Backplate, Impeller, Diffuser, and Mechanical Seal Exploded View
NOTE This is a two-part replacement process. The mechanical seal must be replaced
as a set.
Do not damage the ceramic or carbon surfaces of the seals. If surfaces are
damaged, leaks will occur.
1. To access the mechanical seal, comply with the warning and follow steps 1 through 8
of
Section 6.2.2, Impeller Removal.
2. Remove the carbon face seal half from the impeller sleeve.
(See Figure 5.)
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.
• Ceramic Face Seal
• Backplate Seal
Figure 5a. Mechanical Seal
CAUTION VERY IMPORTANT! Grasp the lower portion of the seal (opposite the carbon
face) when installing the seal or it will be damaged.
NOTE: To assist assembly, only use water or a soap solution as a lubricant. Any other
lubricant will destroy the seal after a short period of time.
NOTE: Exercise great care to keep the seal and mating parts clean.
1. While holding the motor shaft with a flat screwdriver from behind, thread the impeller
onto the motor shaft. Hand-tighten the impeller until it is secure.
2. Replace the motor fan cover and secure it with its 4 screws.
3. Replace the white impeller sleeve over the front (entry port) of the impeller.
4. Replace the diffuser over the impeller, using care to insert alignment pins into the
correct holes. The alignment pins in the diffuser allow the diffuser to be inserted only
one (1) way. Align the arrow onto the backplate with the arrows on the diffuser.
5. Replace the two (2) small Phillips-head screws. Tighten the screws to draw the diffuser
against the motor backplate.
6. Make sure the diffuser o-ring, o-ring groove, and o-ring seal area are clean and free of
debris, which could cause a leak. If you removed the diffuser o-ring during disassembly,
re-install it on the diffuser, as shown in
Figure 6.
If grease is used to retain the diffuser
o-ring, it
must be silicone based. Do not use petroleum-based grease.
It will destroy
the o-ring.
