Pump Relay (Procedure 10)
Wear Personal Protective Equipment when conducting step 2 of this
procedure to reduce the risk of electric shock. Refer to Rheem Safety
Procedure on electrical testing.
1. Isolate power supply to the water heater and remove pump access panel (refer to
procedure 4).
2. Confirm with a multi-meter between Active and Neutral, then Active and Earth,
then Neutral and Earth terminals of the control board power input plug that
voltage is not present (refer to diagram on page 15 for plug location).
3. Unplug pump relay plug from control board.
4. Disconnect pump 1 wire from N/O terminal of pump relay.
5. Remove pump relay retaining screw and remove pump relay.
6. Complete reassembly in reverse order of above.
7. Restore electricity supply and check appliance operation.
Remote Solar Monitor (Procedure 11)
Wear Personal Protective Equipment when conducting step 2 of this
procedure to reduce the risk of electric shock. Refer to Rheem Safety
Procedure on electrical testing.
1. Isolate the power supply to the water heater and remove pump access panel (refer
to procedure 4).
2. Confirm with a multi-meter between Active and Neutral, then Active and Earth,
then Neutral and Earth terminals of the control board power input plug that
voltage is not present (refer to diagram on page 15 for plug location).
3. Unplug remote solar monitor plug from control board.
4. Remove existing remote solar monitor by peeling away from pump access panel and
then withdrawing ribbon cable through the slot in the pump access panel.
5. Remove adhesive backing from replacement solar monitor and complete reassembly
in reverse order of above.
6. Replace pump access panel, restore electricity supply and check appliance operation.
Cold Sensor (Procedure 12)
Ensure any escaping solar circuit fluid is contained and does not enter any
part of a rainwater tank system as entry will render the water undrinkable.
1. Remove the solar circuit relief valve by following steps 1 – 6 in procedure 2. This will
relieve the solar circuit pressure. Note: ensure all warnings in procedure 2 are
observed and adhered to.
2. Unplug cold sensor plug from control board.
3. Turn heat exchanger isolation valve off by rotating clockwise 90º.
4. Remove the spring clip retaining the cold sensor in the pipe work ‘tee’, and remove the
locating washer and cold sensor. Note: a small amount of solar circuit fluid will drain
from the cold sensor aperture during this procedure; have the replacement sensor
ready to quickly install so fluid loss is minimised.
5. Fit the replacement sensor into the “tee” and secure with the spring clip. Ensure the
clip retains the locating washer.
6. Complete reassembly in reverse order of above.
7. Restore electricity supply and check appliance operation.
