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 6.
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 power for the electrically operated components. The removal of the side
cover will expose 240 V wiring. It must only be removed by a qualified person.
Care should be taken not to touch any exposed pipe work or fittings connecting the solar storage tank and
the solar collectors, as this may result in a burn injury. Very high temperature closed circuit fluid or hot water
and in some circumstances high temperature steam 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.
Note:
Any exposed pipe work or fittings in the solar circuit should be attended to and covered with insulation.
Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
Should the water from a 52H or RLX series water heater appear blue or if blue closed circuit fluid is noticed
around the base of the water heater or solar collectors, this indicates a leak of the closed circuit fluid from the
heat exchanger or the solar collectors. The closed circuit fluid is non-toxic and not hazardous to health.
Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
SAFETY
This water heater is supplied with a thermostat, an over-temperature cut-out, 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 on the thermostat 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 a
qualified person.
If the electrical conduit to the solar storage tank is damaged, it must be replaced by a qualified person in
order to avoid a hazard. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an
inspection.
Warning:
For continued safety of this water heater it must be installed, operated and maintained in
accordance with the Owner‟s Guide and Installation Instructions.
The Rheem warranty may not cover faults if relief valves or other safety devices are tampered with or
if the installation is not in accordance with these instructions.
