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. Recover refrigerant charge.
4. Cut cable ties and disconnect pressure switch wiring from terminals 8 and 9 of the
terminal block pulling wires through control panel grommet.
5. Unscrew and remove high pressure switch from refrigeration pipe.
6. Reassemble in reverse order of above.
7. Recharge system with R22. Refer to “refrigerant charge” on page 11.
Control Board: (Procedure 7)
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 (see procedure 1).
2. Confirm with a multi-meter between Active and Neutral at the Compressor

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.
3. Disconnect wiring from pressure switch.
4. Remove pressure hose from rear of pressure switch by closing spring clamp with pliers
whilst gently pulling hose.
5. Unscrew retaining nut from rear of switch and remove pressure switch.
