Pool and Spa Pump Installation and User’s Guide
This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical
Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or serious
injury to pool users, installers, or others due to electrical shock, and may also cause damage to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in death
or serious injury to serviceman, pool users or others due to electric shock.
Read all servicing instructions before working on the pump.
MAINTENANCE
Cleaning the Strainer Basket
The only routine maintenance needed is inspection/
cleaning of the strainer basket. Debris or trash that collects
in the basket will choke off water flow through the pump.
Follow the instructions below to clean the strainer basket:
1. Disconnect power to the pump at the circuit breaker.
2. Close all gate valves in the suction and discharge lines.
3. Release all pressure from the pump and piping system.
4. Remove strainer lid (turn counter-clockwise). If
necessary, tap handles gently with a rubber mallet.
5. Remove the strainer basket and clean. Be sure all holes
in basket are clear.
6. Flush basket with water and place back into the strainer
pot.
Note:
Ensure the large opening in the basket is
oriented towards the pipe connection port (between ribs
provided). If the basket is replaced backwards the lid
will not fit on the strainer pot.
7. Clean and inspect the lid O-Ring and reinstall on
strainer groove.
8. Clean the O-Ring groove on the strainer pot and
reinstall the lid/locking ring.
Note:
To prevent sticking, hand tighten only.
9. Prime the pump (see
Priming the Pump,
page 4).
Pump Disassembly / Removing Old Seal
1. Disconnect power to the pump at the circuit breaker.
2. Close all gate valves in the suction and discharge
lines.
3. Release all pressure from the pump and piping
system.
4. Drain the pump by removing the drain plugs at the
bottom of the strainer pot.
5. Remove the band clamp that holds the pump halves
together. The motor and seal plate assembly can now
be pulled away from pump body.
6. Remove the five (5) screws and washers securing the
diffuser to the seal plate. Remove the diffuser.
7. Carefully remove the motor canopy, being sure not to
touch the capacitor terminals. Loosen the capacitor
clamp and move it to one side.
8. Hold the motor shaft with a 1/2” open-end wrench on
the motor shaft flats.
9. Unscrew the impeller from the motor shaft (turning
counterclockwise when facing the impeller).
For models including a center impeller screw, remove
the impeller screw (left-hand thread) and gasket before
removing the impeller. Inspect the gasket for damage
or cracks and replace if damaged.
10. Remove the rotating seal member from the motor
shaft.
11. Remove the four (4) screws securing the seal plate to
the motor.
12. Place seal plate face down on a flat surface and tap
out white ceramic seal (see
Figure 4
).
13. Clean the seal plate’s seal cavity and the motor shaft.
