WARNING:
Before servicing the pump, switch off the circuit breakers at the power source. Severe
personal injury or death may occur if the pump starts while your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker to the pump motor.
2. Remove the pump lid and strainer basket.
3. Look inside pump for debris. Remove any debris found inside.
4. Replace the strainer basket and lid.
5. Switch on the circuit breaker to the pump motor.
6. Turn on the pump, see if the problem is resolved.
7. If the impeller is still blocked with debris and it is not possible to remove the debris using Steps 2 - 4,
the pump will need to be disassembled in order to access the inlet and outlet of the impeller.
WARNING:
Before servicing the pump, switch off the circuit breakers at the power source. Severe
personal injury or death may occur if the pump starts while your hand is inside the pump.
1. Turn off the pump. Switch off the circuit breaker to the pump motor. If you are not replacing the motor,
do not disconnect the electrical wiring.
2. Turn off any valves to prevent pool water from reaching the pump. Drain water from the pump by
loosening the unions or removing the drain plugs.
3. Remove the ten (10) screws connecting the pump casing to the flange.
4. Pull the motor, seal housing, flange out from the pump casing. Remove the pump casing o-ring. The
impeller is connected to the motor shaft.
Removal and Replacement of the Impeller and/or Mechanical Seal
5. Remove the diffuser by gently pulling the diffuser (the
diffuser is the cover over the impeller) horizontally until
the pins clear the seal housing.
6. Place a 5/16” Allen head wrench through the center
hole of the fan cover and into the recess on the end of
motor shaft.
7. While holding the motor shaft, turn the impeller counter-
clockwise.

8. Gently pull the mechanical seal from the impeller shaft noting the way it was originally installed.
CAUTION:
Do not damage the ceramic or carbon surfaces of the seal. If the surfaces are damaged,
leaks will occur.
9. Using water with a small amount of dish soap, brush the impeller shaft for ease of assembly.
