ABOUT YOUR WATER HEATER
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause scalding. Check
the water temperature before use, such as when entering a shower or filling a bath
or basin, to ensure it is suitable for the application and will not cause scald injury.
We recommend and it may also be required by regulations that an approved
temperature limiting device be fitted into the hot water pipe work to a bathroom or
ensuite when the water heater is installed. This will reduce the risk of scald injury.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for one or two 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 at the isolating switch (if installed) near the water

heater or outside of the bathroom, or at the water heater isolating switch on the
switchboard.
 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 or at the isolating switch (if installed) near the water

heater outside of the bathroom, or at the water heater isolating switch on the
switchboard.
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 the isolating switch (if installed)
near the water heater or outside of the bathroom, or at the water heater isolating
switch on the switchboard.
Note: When the electrical supply is switched back on, the water heater will take some
time to reheat the water.
