ABOUT YOUR WATER HEATER

HOW HOT SHOULD THE WATER BE?
The solar control unit will circulate the closed circuit fluid through the
solar collectors until a temperature of approximately 75°C is
reached in the solar storage tank.
During periods of low solar energy gain, the water temperature can
be boosted by the thermostatically controlled electric booster
heating unit. Refer to
“Booster Control”
on page 7.
Solahart recommends the thermostat is set at 60°C to maximise
solar contribution.
Note:
AS 3498 requires that a water heater provides the means to
inhibit the growth of Legionella bacteria in potable water. This water
heater can satisfy this AS 3498 requirement provided the electric
booster is energised for a sufficient period each day and the electric
booster thermostat setting is 60°C or higher.
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 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.
TEMPERATURE ADJUSTMENT
The water heater features a tradesperson adjustable thermostat. This requires a licensed tradesperson to
make any temperature adjustments. The thermostat has a maximum temperature setting of 70°C and a
minimum temperature setting of 60°C.
We advise you have your electrician adjust the thermostat to the lowest setting which meets your needs,
especially if there are young children or elderly people in the home. Refer to
“Hotter Water Increases the
Risk of Scald Injury”
on page 5.
WARNING
This water heater is only intended to be operated by persons who have the experience or the knowledge and
the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical,
sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do
not interfere with the water heater.
This water heater uses 240 V AC electrical power for operation of the control systems and the electrically
operated components. The removal of the front covers will expose 240 V wiring. They must only be removed
by a qualified person.
Care should be taken not to touch the pipe work connecting the solar storage tank and the solar collectors.
Very high temperature closed circuit fluid can be generated by the solar collectors under certain conditions
and flow through the pipe work from the solar collectors to the solar storage tank.
Should the water from the water heater appear blue or if blue closed circuit fluid is noticed around the base
of the water heater, this indicates a leak of the closed circuit fluid from the heat exchanger. The closed circuit
fluid is non-toxic and not hazardous to health. Phone your nearest Solahart Dealer to arrange for an
inspection.
