Thermostat (Procedure 5)
1. Isolate the power to the electric booster circuit.
2. Remove access cover and disconnect the wiring to the thermostat.
3. Slide the thermostat out from under the retaining clamp.
4. Remove any scale from the cylinder surface.
5. Fit the replacement thermostat under the clamp and set temperature at 70ºC.
6. Reconnect the wiring as per the circuit diagram.
7. Refit the access cover.
8. Restore the power supply.
Anode (Procedure 6)
Under normal conditions the anode need not be replaced. To inspect the anode or change
the anode to match the water quality in the area:
1. Drain the water heater. Refer to procedure 1, page 26.
2. Unscrew the anode with a socket or tube spanner until almost out. When the water
level falls below the anode level, refit the cold pipe to the collector and fit the spring clip
into place.
3. Fit anode bar* to anode, completely unscrew and withdraw the anode carefully, using
the bar to counter balance the anode weight.
4. Apply Teflon tape to the replacement anode, fit anode bar and insert anode carefully
into the water heater using the bar to maintain a horizontal position. Ensure the tip of
the anode locates in the solar flow connection and tighten.
5. Remove anode bar, close the T&PR valve, restore the cold water supply and purge air
through the hot taps.
6. Check anode thread for leaks.
7. Refit access cover.
8. Restore the power supply.
*Anode bar is a 600mm piece of 15mm NB galvanised steel pipe with a socket attached.
Sunstat Valve (Procedure 7)
1. Drain the water heater. Refer to procedure 1, page 26.
2. Disconnect the cold water supply pipe.
3. Disconnect the cold pipe.
4. Unscrew the Sunstat valve from the tank.
5. Reassemble in reverse order of above using Teflon tape to seal the Sunstat valve.
6. Close the T&PR valve, restore the water supply and purge air from the system through
the hot taps.
7. Check Sunstat valve connections for leaks.
8. Restore the power supply.
