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 either a single
heating unit or with twin heating units (refer to “Single Element Model” on page 7
and “Twin Element Model” on page 7). The water heaters can be installed indoor
or outdoor if it does not have a supply cord and plug, or indoor only if it is has a
supply cord and plug.
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 22, 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 “Maintenance Requirements”on page 10.
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
(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 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

SINGLE ELEMENT MODEL
This type of water heater has one heating unit with its
own thermostat, located at the base of the water heater.
The heating unit can be connected to an Off-Peak
(overnight) or time controlled supply, Extended Off-Peak
(overnight and day) or Extended time controlled supply,
or a Continuous / Domestic electricity supply. The
thermostat is factory set to 65°C and is tradesperson
adjustable from 60°C to 75°C (80°C for 050 models).
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.
The lower thermostat is factory set to 70°C and is tradesperson adjustable from
60°C to 75°C. The top thermostat has a fixed setting of 60°C.
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 electricity 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.

MAINTENANCE REQUIREMENTS
11
MINOR MAINTENANCE EVERY SIX MONTHS
It is recommended minor maintenance be performed every six (6) months. Minor
maintenance can be performed 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 12.
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 11.
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, it is mandatory 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 months.
Refer to “Minor Maintenance Every Six Months”on page 11. It is very important
the lever is raised and lowered gently. If water does not flow freely from the
drain line when the lever is lifted, then the water heater should be checked by
Rheem Service or their nearest Accredited Service Agent. 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.

MAINTENANCE REQUIREMENTS
12
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 18).
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. Refer to “Minor Maintenance Every
Six Months”on page 11. It is very
important the lever is raised and lowered
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 13).

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
14
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 14.

SATURATION INDEX
The saturation index is used as a measure of the water’s corrosive or scaling
properties. The saturation index figures stated are calculated using a water
temperature of 80°C.
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. Contact Rheem Service or their nearest
Accredited Service Agent if a replacement heating unit is required.
Refer to the Saturation Index chart on page 15. Refer to the cold water
connection detail on page 29 for the position of the expansion control valve.

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 below:

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.
Twin element water heaters
A twin element non-simultaneous model must have power available to the top
heating unit circuit at all times for the water heater to operate as designed.
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 18.
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
18
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 12). 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 29) 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
19
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 18.
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 17.
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 and “Twin 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.

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 (a model with
a supply cord and plug is suitable for indoor installation only). 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.
