ABOUT YOUR WATER HEATER
TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:

Switch off the electrical supply to the solar control unit at the power outlet (refer to the notes below).

Close the cold water isolation valve at the inlet to the water heater.

Refer to the Owner's Guide and Installation Instructions supplied with the in-series water heater for the
procedure to turn off the in-series water heater.

TO TURN ON THE WATER HEATER

Open the cold water isolation valve fully at the inlet to the water heater.

If the solar collector(s) and solar hot and solar cold pipes have been drained, it will be necessary to have
a plumber purge the collector circuit of air.
If the electrical supply to the water heater has been switched off:

Switch on the electrical supply to the solar control unit at the power outlet.
The power outlet must be switched on for the solar control unit to operate and solar gain to be achieved
and for the anti-freeze heating unit to operate and offer additional freeze protection.
