MAINS PRESSURE LIMITS
The water heater is designed to operate at mains pressure by connecting directly to the mains
water supply. If the mains supply pressure exceeds 750kPa, a pressure-limiting valve must be
fitted before the inlet of the heater, rated at 600kPa.
HOW HOT SHOULD THE WATER BE?
When operated in a domestic situation the system‟s outlet temperature should be between
50
o
C and 80
o
C. During periods of low solar energy gain, the water temperature can be
boosted by the thermostatically controlled gas booster for gas boosted systems or electric
booster heating element for electric boosted systems.
The water heater features a tradesperson adjustable thermostat. This requires a licensed
tradesperson to make any temperature adjustments. The thermostat is located inside the
electrical cover( The tank thermostat is factory set at 66°c for electric boost and the gas
booster must be set to 75°c at the time of installation). These temperatures are required to
protect your family from the potential of leigonella.
SAFETY WARNING:
Ensure all sources of electricity are disconnected from the unit before
removing any of the electrical covers.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
We recommend, and it may also be required by regulations, that an approved temperature
limiting device be fitted into the hot water piping to all bathrooms and ensuites. This will keep
the hot water temperature below 50ºC at those outlets. The risk of scald injury will be reduced
and still allow hotter water to the kitchen and laundry.
