ABOUT YOUR WATER HEATER

THERMOSTATS
The thermostats automatically control the electricity supply to the heating units so a constant temperature is
maintained. The thermostats and their protective over temperature cut out are mounted inside the front cover
of the water heater. There is no need to switch the water heater off when it is not in use. The thermostats are
fully automatic and power is only used when heating is required.
TEMPERATURE ADJUSTMENT
The water heater features tradesperson adjustable thermostats. They require a licensed tradesperson to
make any temperature adjustments. We advise the thermostats are adjusted to the lowest temperature
setting that meets your needs, especially if there are young children or elderly people in the premises. Refer
to “Hotter Water Increases the Risk of Scald Injury” on page 4.
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 front
cover will expose 240 V wiring. It must only be removed by a qualified person.
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 water heater 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.

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.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.

If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or
business you should ensure that you have back up redundancy within the hot water system design. This
should ensure the continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs
and building back up redundancy into your hot water supply system.
