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.
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 cover or solar control unit cover will expose 240 V wiring. It
must only be removed by a qualified person.
The power lead from the solar controller must be plugged into a weatherproof electrical outlet if installed
outdoors. Take care not to touch the power plug with wet hands.
Care should be taken not to touch any exposed pipe work or fittings connecting the solar storage tank and
the solar collector(s), as this may result in a burn injury. Very high temperature hot water and in some
circumstances high temperature steam can be generated by the solar collector(s) under certain conditions
and flow through the pipe work from the solar collector(s) 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.
SAFETY
This water heater is supplied with a thermostat, an over temperature energy cut-out, temperature sensors
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 power supply cord or plug to the solar control unit or the electrical conduit to the solar storage tank is
damaged, it must be replaced by a qualified person in order to avoid a hazard. The power supply cord and
plug must be replaced with a genuine replacement part available from Rheem. 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 Vulcan 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.
