Pump Heaters

NOTE:

Wait for the heaters (PH) to cool before perform-

ing maintenance on the pump heaters.

1. Turn the main power switch (MP) on the electrical

control board door to the OFF position to disconnect
the power.

2. Disconnect the cable connector (UB) from the pump

receptacle (UA) on the pump shroud.

3. Remove the four screws (ZA) from the back pump

shroud.

4. Remove the pump heater front shroud.

5. Check for damaged wires and connections.

6. Follow these steps in reverse order to reassemble

the pump heaters (PH). Ensure the heaters are
secure so they cannot rotate on the pump.
