ABOUT YOUR WATER HEATER
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver hot water at temperatures up to 80°C for an
050 model and up to 75°C for a 080 to 315 model, sufficiently hot to cause
severe scalding. Water at these temperatures may have been plumbed to
fixtures where water hotter than 50°C is allowed, such as the kitchen and laundry.
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 the bathroom
and ensuite when this water heater is installed. This will keep the water
temperature below 50°C at the bathroom and ensuite. The risk of scald injury will
be reduced and still allow hotter water to the kitchen and laundry.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating unit so
a constant temperature is maintained. The thermostat and its protective over-
temperature cut-out is mounted inside the front cover of the water heater. There
is no need to switch the water heater off when it is not in use, except when you
are on an extended holiday. The thermostat is fully automatic and power is only
used when heating is required.
TEMPERATURE ADJUSTMENT
This water heater features a tradesperson adjustable thermostat. This requires
a licensed electrical worker to make any temperature adjustments. The
thermostat (bottom thermostat on twin element models) has a maximum
temperature setting of 75°C (80°C for 050 models) and a minimum temperature
setting of 60°C. The top thermostat on a twin element model has a fixed setting
of 60°C and cannot be adjusted.
We advise you to have a licensed electrical worker adjust the thermostat to the
lowest temperature setting that meets your needs, especially if there are young
"Hotter Water Increases The
children or elderly people in your home. Refer to
Risk of Scald Injury"
on page 13.
