Installation & Operation Manual
3. Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Dealer or service
center if you have any questions.
4. Do not use extension cords.
Refer to Figure 8-1 for pump component locations. Exercise extreme care in handling both the rotating and the
stationary sections of the two-part replacement seal. Foreign matter or improper handling will easily scratch the
graphite and ceramic sealing surfaces.
6.1 Shaft Seal Change Procedure
1. Shut off water flow to pump by closing appropriate valves or by plugging both the skimmer outlet port and return
port to pool. Disconnect piping or hoses from the motor/pump assembly.
2. Unscrew seven (7) screws (#10) and remove pump strainer housing (#4) AND diffuser (#7), exposing the impeller.
3. Rotate the impeller in a counterclockwise direction and remove it from the motor shaft.
4. Note how the steel spring section of the old seal is positioned on impeller hub and remove it by pulling from the
impeller.
5. Remove motor fan cover. Then loosen four (4) motor through bolts from the back of motor and remove pump
housing/shroud from the front of the motor.
6. Remove the ceramic stationary portion of the old seal by pressing the white ceramic seat out of the pump housing
recess. If assembly is tight, tap lightly from the "motor" side.
7. Clean and lubricate the impeller stem and the pump housing recess with a dilute solution of non-granulated liquid-
type soap. Do not use petroleum or silicone lubricants as these can contribute to seal leakage.
8. Press the new rotating portion of the seal assembly onto the impeller stem with the polished black graphite surface
facing away from the impeller.
9. Carefully press the stationary ceramic portion of the seal into the recess of the pump housing/shroud, with the
polished flat surface facing out.
10.
Carefully insert the motor shaft through the pump housing/shroud and align with white ceramic stationary
seal assembly in place and secure the motor to pump housing/shroud with four (4) motor through bolts removed in
step #5. Be sure motor base and pump discharge port are positioned properly. Alternately tighten the motor through
bolts until the pump housing is secure. Make certain motor shaft turns freely before proceeding then re-attach motor
fan cover.
11.
Screw the impeller (clockwise) with the rotating portion of seal in place onto the motor shaft. Hand-tighten
the impeller in place.
12.
Clean (replace if necessary) the O-ring and replace on pump cover. Assemble the pump strainer housing (#4)
AND diffuser (#7) to the pump housing with the seven (7) screws removed in step #2. Tighten screws alternately and
evenly.
13.
Reconnect pump to the piping or hoses provided. Open all valves and make sure that the pump strainer housing
is full of water before restarting the pump.
