ABOUT YOUR WATER HEATER
TO TURN OFF THE WATER HEATER

the water heater switched on.
If it is necessary to turn off the water heater:

Switch off the electrical supply at the isolating switch to the water heater.

Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER

Open the cold water isolation valve fully on the cold water line to the water
heater.

Switch on the electrical supply at the isolating switch to the water heater.
GOING ON HOLIDAY?
If you plan to be away from home for one or two nights, we suggest you leave
the water heater switched on. However, if you plan to stay away more than a few
nights, conserve energy by switching the water heater off at either the
switchboard or isolating switch (if one is installed).
Note: When the electrical supply is switched back on, the water heater will take
some time to reheat the water. Depending upon the power supply connection,
hot water may not be available until the next day.
