The fan motor may commence operation without warning. Failure to isolate
the power may result in serious injury if the fan commences operation.
Personnel qualified and licensed to work with refrigerants may only carry
out the following repair procedures to the sealed refrigeration system.
The following procedures assume that all work conducted conforms to the
refrigeration code of good practice. During repair the R22 refrigerant must
be recovered, not vented to atmosphere.
1. Remove control panel cover and access panel (see procedures 1 & 2).
2. Confirm with a multi-meter between Active and Neutral at the Compressor
contactor Line terminals that voltage is not present.
3. Remove the top cover (see procedure 3).
4. Remove compressor terminal box cover by squeezing sides in centre to detach tabs
and then pulling forward.
5. Disconnect terminal box cable plug by grasping rubber flap with pliers and pulling
outwards.
6. Recover refrigerant charge.
7. Un-braze the discharge and suction line pipe work from the compressor.
8. Undo 4 tapped bolts at base of compressor.
9. Lift compressor out of Heat Pump. As the compressor weighs approximately 40
kilograms lifting equipment such as an “A” frame and block and tackle will be required.
10. Reassemble in reverse order of above.
11. Pressurise system to 3000kPa and conduct a leak test.
12. Evacuate system to 300 microns for a period of at least 40 minutes.
13. Recharge system with R22. Refer to “refrigerant charge” on page 11.
Evaporator Fan Relay: (Procedure 13)
Personal Protective Equipment should be worn when conducting step 2 of
this procedure to reduce the risk of electric shock. Refer to Rheem Safety
Procedure on electrical testing.
1. Remove control panel cover (see procedure 1).
2. Confirm with a multi-meter between Active and Neutral at the Compressor
contactor Line terminals that voltage is not present.
3. Disconnect wiring from fan relay paying attention to where each wire is connected.
4. Remove two tapped screws from relay base and remove fan relay.
5. Reassemble in reverse order of above.
Evaporator Fan: (Procedure 14)
Personal Protective Equipment should be worn when conducting step 2 of
this procedure to reduce the risk of electric shock. Refer to Rheem Safety
Procedure on electrical testing.
The fan motor may commence operation without warning. Failure to isolate
the power may result in serious injury if the fan commences operation.
1. Remove control panel cover and access panel (see procedures 1 & 2).
2. Confirm with a multi-meter between Active and Neutral at the Compressor
contactor Line terminals that voltage is not present.
