WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the
purpose of heating potable water. Its use in an application other than this may
shorten its life.
MODEL TYPE
The Rheem® water heater you have chosen is a Stellar™ model with a stainless
steel cylinder. Stellar stainless steel models are available with either a single
heating unit or with twin heating units (refer to “Single Element Model” on page 11
and “Twin Element Model” on page 11). The water heater is suitable for either
indoor or outdoor installation, except a water heater supplied with a power supply
cord and plug is suitable for indoor installation only.
The water in the cylinder is heated by the electric immersion heating unit. A
thermostat controls the temperature. Automatic safety controls are fitted to the
water heater to provide safe and efficient operation.
A 080 to 315 model water heater has a brass plug and a 050 model water heater
has three brass plugs on one side of the tank. A plug blocks off an alternative
connection point and is not to be tampered with or removed.
MAINS PRESSURE
The water heater is designed to operate
at mains pressure by connecting directly
to the mains water supply. If the mains
supply pressure in your area exceeds
that shown on page 26, a pressure
limiting valve must be fitted. The supply
pressure should be greater than 350 kPa
for true mains pressure operation to be
achieved.
HOW HOT SHOULD THE WATER BE?
The water heater features a
tradesperson adjustable thermostat,
which allows you to choose the most
suitable temperature for your hot water
needs. Refer to “Temperature
Adjustment” on page 9.
To meet the requirements of the National
Plumbing Standard the temperature of
the stored water must not be below 60°C.
ABOUT YOUR WATER HEATER

ABOUT YOUR WATER HEATER
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 the 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.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating unit so
a constant temperature is maintained. The thermostat and its protective overtemperature cut-out is 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, except when you
are on an extended holiday. The thermostat is fully automatic and power is only
used when heating is required.
TEMPERATURE ADJUSTMENT
This water heater features a tradesperson adjustable thermostat. This requires
a licensed electrical worker to make any temperature adjustments. The
thermostat (bottom thermostat on twin element models) has a maximum
temperature setting of 75°C (80°C for 050 models) and a minimum temperature
setting of 60°C. The top thermostat on a twin element model has a fixed setting
of 60°C and cannot be adjusted.
We advise you to have a licensed electrical worker adjust the thermostat to the
lowest temperature setting that meets your needs, especially if there are young
children or elderly people in your home. Refer to “Hotter Water Increases The
Risk of Scald Injury” on page 9.

ABOUT YOUR WATER HEATER
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 power supply cord, plug or electrical conduit to the water heater 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.
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.
WARNINGS
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(s) will expose 240 V wiring. It
must only be removed by a qualified person.
Take care not to touch the power plug on a water heater fitted with a power
supply cord and plug with wet hands.
For continued safety of this water heater it must be installed, operated and
maintained in accordance with the Owner’s Guide and Installation
Instructions.

ABOUT YOUR WATER HEATER
SINGLE ELEMENT MODEL
This type of water heater has one heating unit with its
own thermostat, located at the base of the water heater.
Continuous electricity supply
This type of connection is suited to where the storage
capacity is less than the normal daily usage.
Off-Peak electricity supply
This type of connection will only allow heating to occur
during set hours. A volume of water sufficient for the
day’s total use is heated and stored. This type of
heating will be more economical due to reduced tariffs
by the electricity authority.
TWIN ELEMENT MODEL
This type of water heater has two heating units, each with
its own thermostat. One heating unit is at the base of the
water heater and the other near the top.
Bottom heating unit
During normal operation this heating unit supplies all
the hot water.
Top heating unit (Booster)
This heating unit only operates during periods of high
demand to provide an additional supply of heated
water.
Electrical connection
The two heating units are wired for non-simultaneous
operation, so that only one heating unit can operate
at a time. The bottom heating unit is usually
connected to an Off-Peak (overnight) or time
controlled supply and the top heating unit to a
Continuous / Domestic supply. Some electricity
suppliers allow both heating units to be metered at the
Off-Peak or controlled tariff.
NOTE: Power must be available to the top heating unit circuit at all times
for this water heater to operate as designed.

ABOUT YOUR WATER HEATER
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.
The water heater must be maintained in accordance with the Owner’s Guide and
Installation Instructions. Refer to “Maintenance Requirements” on page 14.
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.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for only a few nights, we suggest you leave
the water heater switched on.
If it is necessary to turn off the water heater:
Switch off the electrical supply at the isolating switch to the water heater.
Unplug the power supply cord from the power outlet (power supply cord
model only).
Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER
Open the cold water isolation valve fully on the cold water line to the water
heater.
Plug in the power supply cord at the power outlet (power supply cord model
only).
Switch on the electrical supply at the isolating switch to the water heater.
GOING ON HOLIDAY?
If you plan to be away from home for one or two nights, we suggest you leave
the water heater switched on. However, if you plan to stay away more than a few
nights, conserve energy by switching the water heater off at either the
switchboard or isolating switch (if one is installed).
Note: When the electrical supply is switched back on, the water heater will take
some time to reheat the water. Depending upon the power supply connection,
hot water may not be available until the next day.
