2. Once satisfied, disconnect the active and neutral supply wires from the compressor
contactor Line 1 and Line 2 terminals.
3. Short circuit the Line 1 and Line 2 terminals of the compressor contactor by inserting a
wire bridge between these two terminals.
4. Connect megger leads to the Line 1 terminal of the compressor contactor and earth.
5. Operate megger. A reading above 1 mega-ohm should be obtained.
6. If a reading below 1 mega-ohm is indicated, all component parts will need to be
individually tested to locate the fault. Refer to flow diagram 7 on page 31.
7. Remove bridging wire between Line 1 and Line 2 terminals of the compressor
contactor.
Test No. 3
To check “Continuity” of pool/spa heater electrical circuit.
8. Set multimeter to resistance scale.
9. If a reading between the compressor Line 1 and Line 2 terminals is greater than
approximately 75.9 ohms is indicated, all electrical component parts will need to be
individually tested to locate the fault. Refer to Specifications on page 5 for indicative
resistances.
10. Reconnect active cable to Line 1 terminal and neutral cable to Line 2 terminal on
compressor contactor.
11. Replace fuse. Note: If continuing with any diagnostic procedures do not replace
the fuse.
Component Replacement Procedures
Control Panel cover: (Procedure 1)
1. Isolate the power to the pool/spa heater.
2. Back off top two screws and remove bottom two screws on control panel cover.
3. Slide cover down and out to remove being careful not to damage wiring.
4. Reassemble in reverse order of above.
Access Panel Removal: (Procedure 2)
1. Remove 3 lower and 2 side retaining screws and lift out access panel.
Top Cover Removal: (Procedure 3)
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.
3. Disconnect purple and brown wires from capacitor and push through control panel
grommet.
