ABOUT YOUR WATER HEATER
5
HOW HOT SHOULD THE WATER BE?
The system controls (compressor, evaporator and fan) will
operate until a water temperature of 60 C is reached. During
periods of ambient air temperature below 3°C to 5 C, the water
temperature is boosted automatically, if heating is required, by
the thermostatically controlled electric heating unit.
To meet the requirements of the National Plumbing Standard
the temperature of the stored water must not be below 60 C.
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 thermostats controlling the heat pump and the booster heating unit are factory set and not adjustable.
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 access cover(s) will expose 240 volt wiring. They must only be
removed by an authorised or qualified person.
Do not use aerosols, stain removers and household chemicals near the water heater whilst it is
working. Gases from some aerosol sprays, stain removers and household chemicals are corrosive to the
materials used in the heat pump system.
Do not store swimming pool chemicals, household cleaners, etc., near the water heater.
Ensure the air flow, air inlet louvres and outlet grille are not obstructed in any way at any time.
SAFETY
This water heater is supplied with a thermostat, two over-temperature energy cut-outs and a combination
temperature pressure relief valve. These devices must not be tampered with or removed. The water heater
must not be operated unless each of these devices is fitted and is in working order.
The operation of the over-temperature cut-out indicates a possibly dangerous situation. If the over-
temperature cut-out operates, it must not be reset and the water heater must be serviced by an authorised or
qualified person.
If the electrical supply conduit to the water heater is damaged, it must be replaced by an authorised person
in order to avoid a hazard. Phone your nearest Rheem Service Department or Accredited Service Agent to
arrange for an inspection.
The warranty can become void if relief valves or other safety devices are tampered with or if the
installation is not in accordance with these instructions.
