ABOUT YOUR WATER HEATER
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 a single
heating unit (refer to “Single Element Model” on page 7). The water heaters can
be installed indoor or outdoor.
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.
The water heater has a brass plug on one side of the tank. The plug blocks off
an alternative cold water 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 21, 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 6.
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 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.
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(s) 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.
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.

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 “Regular Care” on page 9.
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.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating unit
so a constant temperature is maintained. The thermostat and its protective
over-temperature 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 tradesperson to make any temperature adjustments. The thermostat
has a maximum temperature setting of 75°C and a minimum temperature
setting of 60°C.
We advise you have your electrician 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 5.

ABOUT YOUR WATER HEATER
7
SINGLE ELEMENT MODEL
This type of water heater has one heating unit with
its own thermostat. The heating unit is at the base
of the water heater and can be connected to a
Continuous or Off-Peak electricity supply. The
thermostat is factory set to 65°C and is
tradesperson adjustable between 60°C to 75°C.
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.
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.
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.
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.

REGULAR CARE
MAJOR FIVE YEAR SERVICE
It is recommended a major five (5) year service be conducted on the water
heater.
Warning: Servicing of a water heater must only be carried out by qualified
personnel. Phone Rheem Service or their nearest Accredited Service Agent.
Note: The five (5) year service and routine replacement of any components,
such as the relief valve(s), are not included in the Rheem warranty. A charge
will be made for this work. Only genuine replacement parts should be used on
this water heater.
The major service includes the following actions:
Replace the temperature pressure relief valve.
Inspect and flush the expansion control valve (if fitted). If required, replace
the valve.
Check the electric heating unit for excessive calcium build up or corrosion
and replace if necessary.
Visually check the unit for any potential problems.
Inspect all connections.
Check the drain line from the safe tray (if one is installed) is not blocked.
Note: The water heater may need to be drained during this service. After the
completion of the service, 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.

REGULAR CARE
10
MINOR SIX MONTH MAINTENANCE
It is recommended minor maintenance be performed every six (6) months by
the dwelling occupant.
The minor maintenance includes:
Operate the easing lever on the temperature pressure relief valve. It is very
important you raise and lower the lever gently. Refer to “Temperature
Pressure Relief Valve” on page 11.
Warning: Exercise care to avoid any splashing of water, as water
discharged from the drain line will be hot. Stand clear of the drain line’s
point of discharge when operating the valve’s lever.
Operate the easing lever on the expansion control valve (if fitted). It is very
important you raise and lower the lever gently. Refer to “Expansion Control
Valve” on page 10.
Check the drain line from the safe tray (if one is installed) is not blocked.
EXPANSION CONTROL VALVE
In many areas, including South Australia, Western Australia and scaling water
areas, an expansion control valve is fitted to the cold water line to the water
heater. The expansion control valve may discharge a small quantity of water
from its drain line during the heating period instead of the temperature pressure
relief valve on the water heater.
Operate the easing lever on the expansion control valve once every six (6)
months. It is very important you raise and lower the lever gently. The
expansion control valve should be checked for performance or replaced at
intervals not exceeding 5 years, or more frequently in areas where there is a
high incidence of water deposits.

REGULAR CARE
11
TEMPERATURE PRESSURE RELIEF VALVE
This valve is near the top of the water
heater and is essential for its safe
operation. It is possible for the valve to
release a little water through the drain line
during each heating period. This occurs as
the water is heated and expands by
approximately 1/50 of its volume.
Continuous leakage of water from the valve
and its drain line may indicate a problem
with the water heater (refer to
“Temperature Pressure Relief Valve
Running” on page 17).
Warning: Never block the outlet of this
valve or its drain line for any reason.
Operate the easing lever on the
temperature pressure relief valve once
every six (6) months. It is very important
you raise and lower the lever gently.
DANGER: Failure to do this may result
in the water heater cylinder failing, or under
certain circumstances, exploding.
Warning: Exercise care to avoid any
splashing of water, as water discharged
from the drain line will be hot. Stand clear
of the drain line’s point of discharge when
operating the valve’s lever.
If water does not flow freely from the drain line when the lever is lifted, then the
water heater must be checked. Phone Rheem Service or their nearest
Accredited Service Agent to arrange for an inspection.
The temperature pressure relief valve should be replaced at intervals not
exceeding five (5) years, or more frequently in areas where there is a high
incidence of water deposits (refer to “Water Supplies” on page 12).

WATER SUPPLIES
This water heater must be installed in accordance with this advice to be
covered by the Rheem warranty.
This water heater is manufactured to suit the water conditions of most public
reticulated water supplies. However, there are some known water chemistries
which can have detrimental effects on the water heater and its operation
and / or life expectancy.
A list of postcodes is available on the Rheem website (www.rheem.com.au)
indicating known areas where the stainless steel cylinder is not covered by the
Rheem warranty due to the water chemistry of the area. The list is not
necessarily exhaustive and there may be areas outside of these postcodes
where the stainless steel cylinder is not covered by the Rheem warranty due to
the water chemistry of the area.
If you are unsure of your water chemistry, you may be able to obtain
information from your local water supply authority. This water heater should
only be connected to a water supply which complies with these guidelines,
which takes precedence over the list of postcodes, for the Rheem warranty to
apply.
It is recommended to install a suitable filter on the cold water supply line to the
water heater if the water supply contains or has a future risk of containing
suspended solids. The Rheem warranty will not cover resultant faults on
components including the stainless steel cylinder due to the effects of sludge
and / or sediment settling in the water heater.
CHANGE OF WATER SUPPLY
The changing or alternating from one water supply to another can have a
detrimental effect on the operation and / or life expectation of a water heater
cylinder, a temperature pressure relief valve and a heating unit.
Where there is a changeover from one water supply to another, e.g. a rainwater
tank supply, bore water supply, desalinated water supply, public reticulated
water supply or water brought in from another supply, then water chemistry
information should be sought from the supplier or it should be tested to ensure
the water supply meets the requirements given in these guidelines for the
Rheem warranty to apply.

WATER SUPPLIES
13
CHLORIDE AND PH
In a high chloride water supply, the water can corrode stainless steel parts and
cause them to fail.
Where the chloride level exceeds 250 mg / L the Rheem warranty does not
apply to a stainless steel cylinder.
pH is a measure of whether the water is alkaline or acid. In an acidic or very
alkaline water supply, the water can attack stainless steel parts and cause
them to fail.
Where the pH is less than 6.0 or greater than 9.5, the Rheem warranty does
not apply to a stainless steel cylinder. Water with a pH less than 6.0 may be
treated to raise the pH.
The water supply from a rainwater tank in a metropolitan area is likely to be
corrosive due to the dissolution of atmospheric contaminants. This may result
in pH of less than 6.0. It is recommended an analysis on the water from a
rainwater tank be conducted prior to connecting this type of water supply to a
water heater with a stainless steel cylinder.
Refer to the pH and Chloride chart on page 13.

SATURATION INDEX
The saturation index is used as a measure of the water’s corrosive or scaling
properties.
In a corrosive water supply, the water can attack copper parts and cause them
to fail. Where the saturation index is less than –1.0, the water is very corrosive
and the Rheem warranty does not apply to a copper sheathed heating unit. A
corrosion resistant heating unit must be used for the Rheem warranty to apply
to the heating unit. This water heater is supplied fitted with a corrosion resistant
heating unit.
In a scaling water supply calcium carbonate is deposited out of the water onto
any hot metallic surface. Where the saturation index exceeds +0.40, the water
is very scaling. An expansion control valve must be fitted on the cold water line
after the non-return valve to protect and for the Rheem warranty to apply to the
temperature pressure relief valve and water heater cylinder.
Where the saturation index exceeds +0.80, the Rheem warranty does not apply
to a stainless steel cylinder or a standard watts density heating unit. A low
watts density heating unit must be used for the Rheem warranty to apply to the
heating unit.
Water which is scaling may be treated with a water softening device to reduce
the saturation index of the water.
Refer to the Saturation Index chart on page 14. Refer to the cold water
connection detail on page 27 for the position of the expansion control valve.
Contact Rheem Service or their nearest Accredited Service Agent if a
replacement heating unit is required.

TOTAL DISSOLVED SOLIDS
The stainless steel cylinder of the water heater is only covered by the Rheem
warranty when the total dissolved solids (TDS) content in the water is less than
600 mg / L.
Note: Some water analysis reports may state the conductivity of the water
rather than the level of total dissolved solids. Conductivity, measured in
microsiemens per centimetre (µS / cm), is directly proportional to the TDS
content of the water. TDS, in mg / L, is approximately 70% of the conductivity in
µS / cm.
SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY
The water heater and its components are not suitable for certain water
chemistries. Those chemistries are listed below. If the water heater is
connected at any time to a water supply with the following water chemistry, the
Rheem warranty will not cover any resultant faults on the components listed

SAVE A SERVICE CALL
Check the items below before making a service call. You will be charged for
attending to any condition or fault that is not related to the manufacture or
failure of a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
Is the electricity switched on?
Inspect the isolating switch marked “HOT
WATER” or “WATER HEATER” at the
switchboard and the isolating switch (if one
is installed) near the water heater and
ensure they are turned on.
Note: Check the electricity supply to which
the water heater is connected. If on an Off-
Peak or time controlled electricity supply,
remember heating hours are restricted
(refer to “Off-Peak electricity supply” on
page 7).
Check the fuse marked “HOT WATER” or “WATER HEATER” at the
switchboard.
Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when
showering. Carefully review the family’s hot water usage. Have your
plumber fit a flow control valve to each shower outlet to reduce water usage.
Temperature pressure relief valve running
Is the relief valve discharging too much water?
Refer to “Temperature Pressure Relief Valve Running” on page 17.
Thermostat setting
Ensure the thermostat setting is appropriate. Have your electrician check
and adjust the thermostat upwards to gain additional hot water capacity.
Refer to “Temperature Adjustment” on page 6.
Warning: Hotter water increases the risk of scald injury.
Water heater size
Do you have the correct size water heater for your requirements? The sizing
guide in the Rheem sales literature and on the Rheem website
(www.rheem.com.au) suggests average sizes that may be needed.

SAVE A SERVICE CALL
17
TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable that this valve
allows a small quantity of water to escape
during the heating cycle. However, if it
discharges more than a bucket full of water
in 24 hours, there may be another problem.
Continuous dribble
Try gently raising the easing lever on the
relief valve for a few seconds (refer to
“Temperature Pressure Relief Valve” on
page 11). This may dislodge a small particle
of foreign matter and clear the fault.
Release the lever gently.
Steady flows for long period (often at
night)
This may indicate the mains water pressure
sometimes rises above the designed
pressure of the water heater. Ask your
installing plumber to fit a pressure limiting
valve.
Warning: Never replace the relief valve with one of a higher pressure
rating.
Heavy flows of hot water until water heater is cold - then stops until
water reheats
The water heater must be switched off at the switchboard. Phone Rheem
Service or their nearest Accredited Service Agent to arrange for an
inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater
(refer to the cold water connection diagram on page 27) it may discharge a
small quantity of water instead of the temperature pressure relief valve on the
water heater. The benefit is that energy is conserved as the discharged water is
cooler.

SAVE A SERVICE CALL
18
HIGHER THAN EXPECTED ELECTRICITY BILLS
Should you at any time, feel your electricity bill is higher than expected, we
suggest you check the following points:
Is the relief valve running excessively?
Refer to “Temperature Pressure Relief
Valve Running” on page 17.
Is one outlet (especially the shower)
using more hot water than you think?
Refer to “Not Enough Hot Water (or No
Hot Water)”on page 16.
Is there a leaking hot water pipe,
dripping hot water tap, etc?
Even a small leak will waste a
surprising quantity of hot water and
electricity. Replace faulty tap washers,
and have your plumber rectify any
leaking pipe work.
Has there been an increase in hot water usage?
An increase in hot water usage will result in an increase in water heater
operation.
Has your water heating tariff rate been increased by your electricity retailer
since your previous bill?
ELECTRICITY TARIFFS
The electricity tariff to which your water heater is connected will determine the
overall operating cost of the system. It is important you are aware of this tariff,
i.e. Off-Peak (overnight) or time controlled supply, Extended Off-Peak
(overnight and day) or Extended time controlled supply, Domestic / Continuous.
For types of tariffs, refer to “Single Element Model” on page 7.
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU
NEED ASSISTANCE, PHONE RHEEM SERVICE OR THEIR NEAREST
ACCREDITED SERVICE AGENT.

INSTALLATION
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING
INSTALLATION STANDARDS
The water heater must be installed:
by a qualified person, and
in accordance with the installation instructions, and
in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local
codes and regulatory authority requirements.
In New Zealand the installation must also conform with the New Zealand
Building Code.
All packaging materials must be removed from the water heater prior to its
installation. This includes the removal of the cardboard base of the carton from
the underside of the water heater.
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.
If this water heater is to be used where an uninterrupted hot water supply is
necessary for the application or business, then there should be redundancy
within the hot water system design. This should ensure the continuity of hot
water supply in the event that this water heater was to become inoperable for
any reason. We recommend you provide advice to the system owner about
their needs and building backup redundancy into the hot water supply system.
WATER HEATER LOCATION
The water heater is suitable for either indoor or outdoor installation. Whether
located outdoor or indoor, the water heater should be installed close to the
most frequently used outlet and its position chosen with safety and service in
mind.
Clearance must be allowed for servicing of the water heater. The water heater
must be accessible without the use of a ladder or scaffold.
Make sure the temperature pressure relief valve lever is accessible and the
front cover, thermostat and heating unit can be removed for service.

INSTALLATION
20
You must be able to read the
information on the rating plate.
Remember you may have to take the
entire water heater out later for
servicing.
The water heater is to be installed at
ground or floor level and must stand
vertically upright on a stable base as
acceptable to local authorities. The
base of the water heater is made of
corrosion resistant material, and it may
be placed directly in contact with the
supporting surface. It is not necessary
to allow for free air circulation under
the base of the water heater.
Note: The water heater should not be placed in direct contact with a concrete
surface that is less than two months old and not fully cured as this may attack
the metal coating of the water heater base. A moisture barrier should be used
between the two surfaces in this instance.
Alternatively, an 080 model may be hung on a wall capable of taking the weight
of the filled water heater. A bracket kit is available from Rheem. Refer to the
instructions supplied with the kit.
Note: If the base of the water heater is higher than the lowest hot water outlet
by 2 m or more, the tank may be subject to a negative pressure (partial
vacuum) which can cause damage to the water heater cylinder. In this
instance, an approved vacuum break valve (RMC AV50A or equivalent) must
be installed at the highest point in the hot water line. Damage to the cylinder
caused by incorrect installation is not covered by the Rheem warranty.
Remember all local authorities have regulations about putting water heaters
into roof spaces.
SAFE TRAY
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. AS/NZS 3500.4 also has
particular requirements when a safe tray must
be installed.
