ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem electric water heater and a Rheem solar
conversion kit. The Rheem solar conversion kit converts your Rheem electric water
heater into a Rheem solar Loline water heater. Your Rheem solar Loline water
heater is designed for the solar collectors to be roof mounted and the solar storage
tank to be installed at ground level. The solar storage tank is suitable for either
outdoor or indoor installation. The system is suitable for installation, and offers
protection against freeze damage, in areas up to 800 metres altitude. The system is
not covered for freeze damage above 800 metres altitude (refer to “Warranty” on
page 40).
The model you have chosen will be either a Rheemglas or an Optima model. The
Optima model has a temperature adjusting knob on the lower front of the water
heater. Both the Rheemglas and Optima models are available with either a single
element or with twin elements (refer to “Single Element Models” on page 11 and

ABOUT YOUR WATER HEATER
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
We recommend, and it may also be required by regulations, that an approved
temperature limiting device, such as the Rheem Temp-Set, be fitted into the hot
water piping to the bathroom and ensuite when this water heater is installed. This
will keep the water temperature below 50LC at the bathroom and ensuite. The risk
of scald injury will be reduced and still allow hotter water to the kitchen and laundry.
This temperature limiting device may be required by regulations.
TEMPERATURE ADJUSTMENT- OPTIMA
To adjust the temperature, push in the child
resistant knob and turn anti clockwise to
decrease or clockwise to increase the
temperature setting. The Optima has a
minimum temperature setting of 60LC and a
maximum temperature setting of 75LC.
WARNING
This water heater is not intended to be
operated, adjusted or tampered with by
young children or infirm persons. Young
children should be supervised to ensure
they do not interfere with the water heater.
Care should be taken not to touch the pipe work connecting the solar collectors and
the solar storage tank. Under certain conditions, very high temperature hot water
can be generated by the solar collectors and flow through the pipe work.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water
heater switched on.
If it is necessary to turn off the water heater:
Sꢀ Close the cold water isolation valve at the inlet to the water heater.
Sꢀ Switch off the electrical supply at the isolating switch to the solar storage tank.
Sꢀ Switch off the electrical supply at the power outlet to the solar control unit
(refer to note below).
Note: If there is a risk of freezing conditions, the electrical supply to the solar
control unit should not be switched off unless the solar collectors are drained,
otherwise damage could result (refer to “Freeze Protection” on page 8).

ABOUT YOUR WATER HEATER
TO TURN ON THE WATER HEATER
Sꢀ Open the cold water isolation valve fully at the inlet to the water heater.
Sꢀ If the solar collectors and solar hot and cold pipes have been drained, it will be
necessary to bleed the collector circuit (refer to “Bleeding the Solar Collectors”
on page 7).
If the electrical supply to the water heater has been switched off:
Sꢀ Switch on the electrical supply to the solar storage tank at the isolating switch
Sꢀ Switch on the electrical supply to the solar control unit at the power outlet.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
installed by an authorised person and the installation must comply with national
codes AS/NZS 3500.4.2, AS/NZS 3000, and all local codes and regulatory authority
requirements. In New Zealand, the installation must conform with the New Zealand
Building Code.
Note: The solar hot and cold pipe work between the solar storage tank and the
solar collectors must be of copper and fully insulated with Armaflex insulation or
similar (minimum thickness 10 mm). The insulation must be weatherproof if
exposed and fitted up to the connections on the storage tank, as very high
temperature water can flow from the solar collectors to the storage tank under
certain conditions. Plastic pipe must not be used, as it will not withstand the
temperature of the water generated by the solar collectors under certain conditions
(refer to Warning on page 29).
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some water
qualities may have detrimental effects on the cylinder, solar collectors and fittings. If
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water heater
will provide. These include the water quality, the water pressure, temperature (inlet
and outlet) and the water usage pattern. However, your Rheem water heater is
supported by a comprehensive warranty (refer to page 40).

ABOUT YOUR WATER HEATER
ANODE PROTECTION
The anode installed in your water heater will slowly dissipate whilst protecting the
cylinder. The life of the water heater cylinder may be extended by arranging for an
authorised person to inspect the anode and replacing it if required.
The suggested time after installation when the anode should be inspected is:
Rheemglas
Optima
8 years
10 years
For softened water supplies or in areas of poor water quality, it is recommended the
anode be inspected 3 years earlier than shown (refer to “Water Supplies” on
page 38).
BLEEDING THE SOLAR COLLECTORS
It is necessary to purge air from the
collector circuit:
Sꢀ When the water heater is to be turned
on and the solar collectors and solar
hot and cold pipes have been drained.
Sꢀ After
maintenance
has
been
conducted on the pipe work and air
has entered the system.
Sꢀ If the circulator appears not to be
circulating water around the system.
To purge air from the collector circuit:
Sꢀ Ensure the solar storage tank is full of
water and all of the hot taps are
turned off.
Sꢀ Using a flat blade screwdriver, open
the bleed valve (if it is not already
open) fitted adjacent to the 5 way tee
at the cold water inlet of the water
heater (see diagram).
air bleed
valve
Sꢀ The mains pressure will force water to flow from the tank and through the pipe
work, expelling air from the collector circuit through the bleed valve. This is
evidenced by spurting of water from the drain line connected to the bleed
valve.
Warning: Exercise caution, as water may be at a very high temperature.
Sꢀ Close the bleed valve when water runs freely from the drain line.

ABOUT YOUR WATER HEATER
FLUSHING THE SOLAR COLLECTORS
It may be necessary to flush the solar collectors if there is sediment in the water
supply. To flush the solar collectors, follow the procedure “Bleeding the Solar
five minutes before closing the bleed valve.
It is recommended to flush the solar collectors every five years. This will assist in
keeping the solar collectors, solar cold pipe and solar hot pipe clear of sediment.
FREEZE PROTECTION
The system is suitable for installation, and offers protection against freeze damage,
in areas up to 800 metres altitude. The system is not covered for freeze damage
above 800 metres altitude (refer to “Warranty” on page 40).
The anti freeze control is designed to recirculate a small amount of water from the
solar storage tank through the solar pipe work during periods of low temperatures.
This is to prevent the water inside the pipe work from freezing. It is essential that
the electrical circuit to the solar control unit is continually turned on if there is a risk
of freezing. The solar warranty does not cover damage caused by freeze conditions
when the electrical circuit to the solar control unit is turned off or interrupted.
Notes:
Sꢀ If it is necessary to switch the power off to the solar control unit and there is a
risk of freezing, then it is necessary to have your plumber drain the solar
collectors and solar flow and return pipe work.
Sꢀ The freeze protection system will be rendered inoperable if electrical power is
not available at the solar control unit. Damage caused by freezing due to no
power at the solar control unit, is not covered by warranty.
Sꢀ Pipe work between the solar collectors and solar storage tank must be
insulated.
Sꢀ The system is not covered for freeze damage above 800 metres altitude.
Sꢀ Refer to “Warranty Exclusions” on page 39.

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 pipe
during each heating period. This occurs as the water
is heated and expands by approximately 1/50 of its
volume. Never block the outlet of this valve or its

line when the lever is lifted, then the water heater should be checked by the Rheem
Service Department of their Accredited Service Agent.
The temperature and pressure relief valve should be checked for performance or
replaced at intervals not exceeding 5 years, or more frequently in areas where
EXPANSION CONTROL VALVE
In South Australia and Western Australia an expansion control valve is fitted to the
cold supply pipe to the water heater. Water will flow from its drain line during the
heating period. In scaling water areas, an expansion control valve should be fitted
to the cold water supply line to the water heater.
SAFETY
This water heater is supplied with a thermostat, an over-temperature cut-out, and a
combination temperature and 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.
If the power supply cord or plug to the solar control unit is damaged, it must be
replaced by an authorised person, in order to avoid a hazard. Phone your nearest
Rheem Service Department or Accredited Service Agent to arrange for an
inspection.
The warranty can become void if relief valves or other safety devices are
tampered with or if the installation is not in accordance with these
instructions.
SOLAR COLLECTOR GLASS
Ensure the glass on your solar collectors is free of dust, salt spray or any other
matter, which may reduce the effectiveness of the solar collectors. Hose or wash
the collector glass with water and a soft brush when the solar collectors are cool.
Trim any trees which may shade the solar collectors.

HOW YOUR WATER HEATER WORKS
The Rheem solar Loline system has its vitreous enamel lined solar storage tank
installed at ground or floor level, remotely from the solar collectors. As the sun
heats the water in the solar collectors the increase in temperature activates the
circulator. The circulator then moves the water from the solar collectors through an
insulated copper pipe to the solar storage tank. The circulator switches on
whenever the water in the solar collectors is hotter than the water in the tank.
Cooler water from the solar storage tank is circulated to the solar collectors to be
heated by the sun’s energy. This process continues while solar energy is available
and until the water in the solar storage tank reaches a temperature of
approximately 75LC.
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
should be greater than 350 kPa for true mains pressure operation to be achieved.
ELECTRIC BOOSTING
Water stored in the solar storage tank can be heated by an electric booster heating
unit. The booster heating unit is for heating the water at times of low solar energy
gain, such as during very cloudy or rainy weather, or during the winter months.
The booster heating unit is controlled by an
electric thermostat. The thermostat and its
over temperature energy cut out are
mounted on the solar storage tank behind
the front cover. The water temperature is
automatically controlled to the thermostat
setting when the booster heating unit is
energised.
The Optima models feature a user
adjustable thermostat, which allows you to
choose
the
most
suitable
boost
temperature for your hot water needs. It
has a minimum temperature setting of
60LC and a maximum temperature setting
of 75LC. The thermostat on the Rheemglas
models is tradesperson adjustable. It has a
minimum temperature setting of 60LC and
a maximum temperature setting of 70LC. It
can only be adjusted by an authorised
person. Automatic safety controls are fitted
to the water heater to provide safe and
efficient operation.

HOW YOUR WATER HEATER WORKS
SINGLE ELEMENT MODELS
Sꢀ Continuous electricity supply
This type of connection is suited to
where the storage capacity is less than
the normal daily usage.
Sꢀ Off-Peak electricity supply
This type of connection will only allow
boosting to occur during set hours. A
volume of water sufficient for the day’s
total use is heated and stored. This
type of boosting may be more
economical due to reduced tariffs by
the electricity authority.
TWIN ELEMENT MODELS
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.
Sꢀ Lower heating unit
During normal operation this heating
unit supplies all of the boosted hot
water during periods of low solar
energy gain.
Sꢀ Top heating unit
This heating unit only operates during
periods of high demand to provide an
additional supply of boosted water.
Sꢀ Electrical connection
The two heating units are wired for non
simultaneous operation and only one
heating unit can operate at a time. The
lower heating unit is usually connected
to the Off-Peak electricity supply and
the top heating unit to a continuous
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.

HOW YOUR WATER HEATER WORKS
MANUAL CONTROLS
An isolating switch is installed in your electrical meter box for your solar water
heater. Rheem recommends as an optional extra a second switch, called the
Booster Switch, be installed in a convenient location such as the kitchen or laundry.
This switch should be a normal on/off manually operated switch (recommended for
Off-Peak electricity supplies to single element models and the bottom element on
twin element models) or the Rheem “One Shot Control” switch (recommended for
continuous electricity supplies to single element models only).
The amount of water heated by the booster heating unit depends on the model of
water heater installed. The boosted volumes of hot water are:
Model
250 L
250 litres 315 litres 400 litres
50 litres 50 litres 90 litres
315 L
400 L
Lower Heating Unit (all models)
Top Heating Unit (twin element models)
MANUAL ON/OFF SWITCH
(a) Continuous Tariff Connection
Operate the booster switch to activate the
auxiliary booster heating unit when the hot
water falls below an acceptable temperature.
It is important to ensure the booster switch is
turned OFF after you have satisfied your hot
water needs. Do not leave the booster switch
ON in sunlight hours because your solar
savings will be reduced.
(b) Extended Off-Peak Tariff Connection
Operation is very similar to that suggested for
continuous tariff, but it is important to be
aware of the hours during which electricity is
available so boosting, if required, can be
adapted to suit. (Check with your local
Electricity Supply Authority for hours of
operation). Do not leave the booster switch on
during daylight hours unless boosting is
required, as solar savings will be reduced.
(c) Off-Peak (night rate) Tariff Connection
Most systems will be connected to an Off-Peak supply of electricity. Boosting will
only occur overnight (usually between 11:00 PM and 6:00 AM). In the winter
months many households will find it necessary to leave the booster switch ON.
However, in some cases it may only be necessary to switch the booster switch ON
every second night. This can be determined over a trial period.

HOW YOUR WATER HEATER WORKS
“ONE SHOT CONTROL” SWITCH
The “One Shot Control” switch has been specially developed to help provide
maximum savings with electrically boosted solar water heaters connected to a
continuous electricity supply. Power must be available to the “One Shot Control”
switch before the booster heating unit can be activated.
The switch has a push button operation
and incorporates a neon light indicator.
This neon light will come on when the
water in the boosted section of the solar
storage tank falls more than 6°C below
the
thermostat
setting,
indicating
boosting may be required.
When you decide the hot water is below
a usable temperature and additional hot
water is required, press the control
button. The neon light will go out and the
booster heating unit will be turned “ON”.
The booster heating unit is automatically
turned
“OFF”
when
the
water
temperature reaches the thermostat
setting.
It is not necessary to activate the booster heating unit every time the neon light is
on (the neon light indicates the water is more than 6°C below the thermostat
setting). The water may still be at a usable temperature for some purposes (e.g.
showering) and you may not need to use hot water for some hours during which
time the water may be heated by the sun.
Remember, even on cloudy days your solar water heater can receive diffused
radiation, which will heat some of your stored water. On these days you will
need to operate the booster heating unit only as desired. For summer
operation it is recommended trial periods be undertaken to determine if it is
necessary to turn the booster switch or one shot control ‘on’ at all.
GOING ON HOLIDAYS
If you plan to be away from home for a few nights, we suggest you leave the water
heater switched on. If you plan to be away for a longer period, conserve energy by
switching the booster switch “OFF”. It is not necessary to switch off the electrical
supply at the power outlet to the solar control unit. Refer to “To Turn Off The Water
it is recommended the solar collectors be covered.

attending to any condition or fault that is not related to manufacture or failure of a
part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
Sꢀ Insufficient sunlight
Insufficient sunlight due to cloudy
weather during summer months or low
solar energy contribution in winter
months may mean you will need to switch
on the booster heating unit more often.
Sꢀ Booster heating unit not operating
Inspect the isolating switch marked “HOT

switchboard and the booster switch (if
one is installed) and ensure they are
turned “ON”. Check the electrical tariff to
which the unit is connected. If on Off-
Peak remember heating hours are
restricted (refer to “Off-Peak Tariff” on
heater”.
Check the fuse marked “HOT WATER” or “WATER HEATER” at the switchboard.
Sꢀ Twin element models
For twin element non simultaneous models power must be available to the top
heating unit circuit at all times for this water heater to operate as designed.
Sꢀ Solar Control Unit
Check the power outlet to the solar control unit is switched on.
Sꢀ Collectors shaded
If trees or other objects shade the solar collectors or if the glass is dirty, the
effectiveness of the solar collectors will be greatly reduced. Clean the collector
glass, trim trees or relocate the solar collectors if the obstruction is permanent.
Sꢀ Collector area is too small
For most installations, the number of solar collectors recommended in Rheem
literature has been proven to provide the required solar energy to meet the
average family needs. However, in some circumstances, it may be necessary to
install an additional solar collector.

Sꢀ Air in collectors (no solar gain)
It is possible under certain conditions, such as when the pipe work has been
opened, that air may become trapped in the solar collectors. This will prevent the
circulator from moving water around the collector circuit. The air will need to be
purged from the solar collectors (refer to “Bleeding The Solar Collectors” on
Sꢀ Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Carefully review the family’s hot water usage. As you have installed an energy
saving appliance, energy saving must also be practised in the home. Adjust your
water usage pattern to take advantage of maximum solar gains. Still have
enjoyable showers, but restrict the amount of hot water used by simply fitting an
inexpensive flow control valve to your shower rose.
Sꢀ Temperature and pressure relief valve running
Is the relief valve discharging too much water? (Refer to “Temperature and
Pressure Relief Valve Running” on page 16).
Sꢀ Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to adjust (Optima
models) or have your electrician adjust (Rheemglas models) the thermostat
upwards to gain additional hot water capacity when boosting.
Sꢀ Water heater size
Do you have the correct size water heater for your requirements? The sizing
suggest average sizes that may be needed.
WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage or low solar energy gain the water
temperature may be lower than normally expected. You will need to carefully plan
your use of the booster heating unit to boost the water temperature on such
occasions.
A lower water temperature may also be noticed in the morning when the booster
heating unit has not been switched on overnight. This in particular may be
experienced during periods of low solar energy gain, or if there has been heavy hot
water usage the previous night.

HIGH ELECTRICITY BILLS
With the installation of your new solar hot water system, maximum electrical energy
savings can be achieved with careful planning of hot water usage. Should you at
any time, feel your electricity account is too high, we suggest you check the
following points:
Sꢀ Is the relief valve running excessively?
(Refer to “Temperature and Pressure
Sꢀ Is one outlet (especially the shower)
using more hot water than you think?
(Refer to “Not Enough Hot Water” on
page 14).
Sꢀ 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 energy.
Replace faulty tap washers, and have
your plumber rectify any leaking pipe
work.
Sꢀ Are you using the booster heating unit properly? (Refer to “Manual On/Off
Sꢀ Consider recent changes to your hot water usage pattern and check if there
has been any increase in tariffs since your previous account.
ELECTRICITY TARIFFS
The electricity tariff to which your solar water heater is connected will play an
important role in the overall effectiveness of the system. It is important you are
aware of this tariff to enable you to take full advantage of the boosting period,
i.e. Domestic/Continuous, Off-Peak, Extended Off-Peak. For types of tariffs (refer to
“How Your Water Heater Works” on page 12).
COLLECTOR GLASS
Warranty DOES NOT cover breakage of solar collector glass. Check your
household insurance policy covers collector glass breakage. Warning: Collector
glass should not be replaced whilst the solar collector is on the roof. The solar
collector must be disconnected and brought to ground level before replacing the
collector glass. Should the glass on a solar collector require replacement, contact
your nearest Rheem Service Office or Accredited Service Agent.

SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the water
heater jacket, we recommend the use of self-drilling screws with a maximum length
of 12 mm. Should pre drilling be required, extreme caution must be observed when
penetrating the jacket of the water heater.
Note: Damage to the cylinder as a result of saddling to the jacket will void the
warranty.
BOOSTER HEATING UNIT
The booster heating unit(s) provides hot water during periods of low solar gain.
Single element models can be connected to either an Off-Peak electricity supply or
a continuous electricity supply. Twin element models are to be connected with the
bottom heating unit on an Off-Peak electricity supply and the top heating unit on a
continuous electricity supply. Boosting can be controlled via a user operated
manual switch. Refer to “Manual Controls” on page 33.

INSTALLATION – SOLAR COLLECTORS
SOLAR COLLECTOR LOCATION
Solar collectors must be installed in a shade free position and located as follows:
Sꢀ The solar collectors are to installed
facing toward the equator (i.e. north
facing in the southern hemisphere
and south facing in the northern
hemisphere). Where this orientation is
not practical, a system facing up to
45L from the equator will have its
efficiency reduced by approximately
5%.
Sꢀ Inclination of the solar collectors
should be approximately equal to the
local latitude angle. The latitudes of
some Australian cities are listed
below. Solar collectors may be
installed at the roof angle for
simplicity
of
installation
and
appearance, but must never be flat. If
the roof angle varies by 15L from the
correct angle, efficiency will be
reduced by 5%.
Sꢀ A flat roof stand is required for
installations where the roof angle is
less than 10L.
Sꢀ The collector kit is suitable for
installations with an inclination of up
to 30L. Where the solar collectors are
installed at inclinations greater than
30L, special roof fixings may be
necessary. Refer to your local Rheem
Solar Distributor for details.
Sꢀ The installation of the solar collectors must comply with the requirements of
AS/NZS 3500.4.2 and all local codes and regulatory authority requirements.
Sꢀ The roof must be suitable to take the mass of the solar collectors. Each solar
collector weighs 34 kg when full of water.

INLET/OUTLET CONNECTIONS
A disconnection union must always be provided at the cold water inlet and hot
water outlet on the water heater to allow for disconnection of the water heater.
All water heaters have a plastic dip tube or fitting liner in the inlet and outlet fittings
(see diagram). These must be in place for the water heater to function properly. Do
not remove or damage them by using heat nearby. They will be pushed into the
correct position as the fitting is screwed in.
A non return valve must be installed on the cold water supply pipe to the solar
storage tank. Use the arrangement shown in the installation diagram (refer to
before connection and purged before attempting to operate the water heater.
PIPE SIZES
The solar cold and hot pipes between the solar storage tank and the solar
collectors should be a minimum DN15. The cold water pipe to the water heater
should be the same size or bigger than the hot water line from the water heater. For
best results, choose the most suitable pipe size for each individual application.
Refer to the relevant plumbing regulations.

CONNECTIONS - PLUMBING
WARNING: Plumber – Be Aware:
Sꢀ The solar cold and hot pipes between the solar storage tank and the
solar collectors MUST BE of copper and fully insulated with Armaflex
insulation or similar (minimum thickness 10 mm).
Sꢀ The insulation must be weatherproof if exposed and fitted up to the
connections on both the solar collectors and the storage tank, as
very high temperature water can flow from the solar collectors to the
solar storage tank under certain conditions. The insulation will also offer
corrosion protection to a metal roof against water runoff over the copper
pipe.
Sꢀ Plastic pipe MUST NOT be used, as it will not withstand the temperature
of the water generated by the solar collectors under stagnation
conditions. The solar collectors can generate extremely high water
temperatures, up to 150LC, and high water pressure of 1000 kPa. Plastic
pipe cannot withstand these temperatures and pressures, and MUST
NOT be used. Failure of plastic pipe can lead to the release of high
temperature water and cause severe water damage and flooding.
Sꢀ There must be a continuous fall in the pipe work between the solar
collectors and storage tank. The highest point of the solar cold pipe and
solar hot pipe must be where they connect to the solar collectors, to
avoid the possibility of air locks occurring in the system.
PIPE LENGTHS
The maximum recommended combined length of the solar cold and solar hot pipes
with bends is:

RELIEF VALVE
The Temperature and Pressure Relief valve must be fitted before the water heater
is operated. Before fitting the relief valve, make sure the probe has not been bent.
Seal the thread with Teflon tape - never hemp. Make sure the tape does not hang
over the end of the thread.
Screw the valve into the correct opening (refer to the installation diagram on
valve body - use the spanner flats provided.
RELIEF VALVE DRAIN
A drain pipe must be fitted to the relief valve to carry the discharge clear of the
water heater. Connect the drain line to the relief valve using a disconnection union.
The pipe work from the relief valve to the drain should be as short as possible, and
fall all the way from the water heater with no restrictions. It should have no more
than three right angle bends in it. Use DN15 pipe. The outlet of the drain pipe must
be in such a position that flow out of the pipe can be easily seen (refer to
AS/NZS 3500.4.2) - but arranged so hot water discharge will not cause injury,
damage or nuisance. The relief line must discharge at an outlet or air break not
more than 9 metres from the relief valve.
In locations where water pipes are prone to freezing, the drain pipe must be
insulated and not exceed 300 mm in length. In this instance, the drain pipe is to
discharge into a tundish through an air gap of between 75 mm and 150 mm.
Warning: As the function of the Temperature and Pressure Relief valve on this
water heater is to discharge high temperature water under certain conditions, it is
strongly recommended the pipe work downstream of the relief valve be capable of
carrying water exceeding 93LC. Failure to observe this precaution may result in
damage to pipe work and property.
BLEED VALVE DRAIN
A drain pipe must be fitted to the bleed valve to carry the discharge clear of the
water heater and solar controls. Connect the drain line to the bleed valve using a
disconnection union. The pipe work from the bleed valve to the drain should be as
short as possible, and fall all the way from the valve with no restrictions. It should
have no more than three right angle bends in it. Use DN15 pipe. The outlet of the
drain pipe must be in such a position that flow out of the pipe can be easily seen
(refer to AS/NZS 3500.4.2) - but arranged so water discharge will not cause injury,
damage or nuisance. The water discharged may be of a high temperature under
certain conditions.

EXPANSION CONTROL VALVE
Local regulations may make it mandatory to install an expansion control
valve (ECV) in the cold water supply line. In other areas ECVs are not required
unless the saturation index is greater than +0.4 (refer to “Water Supplies” on
sufficient quantities of silica dissolved in the water. A drain line must be run
separately from the drain of the relief valve.

CONNECTIONS - ELECTRICAL
The power supply must not be turned on until the solar storage tank is filled with
water, and a satisfactory megger reading is obtained. The solar storage tank with
an electric booster heating unit is designed for direct connection to a
240 V AC 50 Hz mains power supply with an isolating switch installed at the
switchboard.
Flexible 20 mm conduit is required for the electrical cable to the solar storage tank.
The conduit is to be connected to the unit with a 20 mm terminator. Connect the
power supply wires directly to the terminal block and earth tab connection, ensuring
there are no excess wire loops inside the front cover.
The solar control unit, supplied with a 1.8 metre power cord, requires a 240 V
general power outlet (GPO) to be located within 1.2 metres of the installation. The
GPO is required to be weatherproof for outdoor installations. If the power supply
cord is damaged, it must be replaced in order to avoid a hazard.
ASSEMBLY OF ADJUSTER MECHANISM ON OPTIMA MODELS
When the front cover has been removed,
reassemble as follows:
Sꢀ Remove the knob from the front cover
by depressing the locking tabs on the
inside of the front cover.
Sꢀ Turn the thermostat to the lowest
temperature (refer to “Temperature
Adjustment – Optima” on page 5).
Sꢀ Fit the front cover.
Sꢀ Insert the connector shaft through the
hole into the thermostat adaptor slots.
Sꢀ Align the knob slots over the ‘T’ drive on
the connector shaft, with the dial at the
lowest setting – a firm push with the
hand on the knob front face will engage
the locking tabs.
THERMOSTAT SETTING
The water heater thermostat should be set at the lowest temperature that will
provide sufficient hot water. Discuss with the user to determine the lowest
thermostat setting to ensure sufficient quantities of hot water. Dishwasher running
costs can be adversely affected if the thermostat is set below 65LC. The thermostat
can be adjusted within the range shown on page 4.

COMMISSIONING
TO FILL AND TURN ON THE WATER HEATER
The power supply to the solar storage tank and solar control unit must not be
switched on until the water heater is filled with water and a satisfactory megger
reading is obtained.
Sꢀ Open all of the hot water taps in the house (don’t forget the shower). Open the
cold water isolation valve fully to the water heater. Air will be forced out of the
taps. As water flows freely from each tap, close it. Check the piping for leaks.
Sꢀ Bleed the solar collectors (refer to “Bleeding the Solar Collectors” on page 34).
Sꢀ Switch on the electrical supply at the isolating switch to the solar storage tank.
Sꢀ Plug in the solar control unit and switch the power on.
Explain to the householder the functions and operation of the solar water heater.
BLEEDING THE SOLAR COLLECTORS
Upon completion of the installation, it is necessary to purge the air from the
collector circuit. To purge air from the collector circuit:
Sꢀ Ensure the solar storage tank is full of
water and all of the hot taps are turned
off.
Sꢀ Using a flat blade screwdriver, open
the bleed valve fitted adjacent to the
5 way tee at the cold water inlet of the
water heater (see diagram).
Sꢀ The mains pressure will force water to
flow from the tank and through the
pipe work, forcing air from the collector
circuit through the bleed valve. This is
evidenced by spurting of water from
the drain line connected to the bleed
air bleed valve
valve.
Warning: Exercise caution, as water may be at a very high temperature.
Sꢀ Close the bleed valve when water runs freely from the drain line.

COMMISSIONING
TO TURN OFF THE WATER HEATER
If it is necessary to turn off the water heater on completion of the installation, such
as on a building site or where the premises is vacant, then:
Sꢀ Close the cold water isolation valve at the inlet to the water heater.
Sꢀ Switch off the electrical supply at the isolating switch to the solar storage tank
and at the power outlet for the solar control unit.
Note: The freeze protection system will be rendered inoperable if electrical power is
not available. Damage caused by freezing due to the unavailability of power to the
solar control unit is not covered by warranty (refer to “Warranty Exclusions” on
collectors and connecting pipe work (refer to “Draining the Solar Collectors” on

5 way tee at the cold water inlet of the water heater (refer to diagram on
Sꢀ Undo the compression fitting at the top of the circulator (located at the side of
the solar control unit) and disconnect the solar cold pipe. Water will now drain
from the solar collectors and the solar hot and cold pipes.
Sꢀ When water stops flowing from the solar hot and cold pipes, reconnect the
solar cold pipe to the circulator and tighten the compression fitting. Close the
bleed valve.
DRAINING THE WATER HEATER
Sꢀ Switch off the electrical supply at the isolating switch to the solar storage tank
and at the power outlet for the solar control unit.
Sꢀ Close the cold water isolation valve at the inlet to the water heater. Close all
hot water taps.
Sꢀ Operate the relief valve release lever - do not let the lever snap back or you
will damage the valve seat. Operating the lever will release the pressure in the
water heater.
Sꢀ Undo the union at the cold water inlet to the 5 way tee and attach a hose. Let
the other end of the hose go to a drain.
Sꢀ Operate the relief valve again. This will let air into the water heater, and allow
the water to drain through the hose.

WATER SUPPLIES
Your Rheem water heater is manufactured to suit the water conditions of most Australian
metropolitan supplies. However, there are some known water supplies which can have
detrimental effects on the water heater and its operation and/or life expectancy. If you are
unsure of your water quality, you can obtain information from your local water supply
authority.
ANODE
By using the correct colour coded anode this water heater can be used in areas where the
total dissolved solids (TDS) content in the water is up to 2500 mg/L. In areas where the
TDS exceeds 600 mg/L it is possible the black anode, which is the standard anode fitted to
the water heater, may be excessively active. To alleviate this, the black anode should be
replaced with one colour coded blue. Where the TDS of the water is less than 40 mg/L,
such as when the water has been deionised or is from an alpine supply, a high potential
anode, colour coded green, should be used. The changing of anodes must be carried out
by a plumber or authorised service person.
CAUTION
If your water supply has a TDS greater than 600 mg/L and the anode has not been
changed to a blue one, there is the possibility hydrogen gas could accumulate in the top of
the water heater during long periods of no use.
If, under these conditions, the water heater has not been used for two or more weeks the
following procedure should be carried out before using any electrical appliances
(automatic washing machines and dishwashers) which are connected to the hot water
supply.
The hydrogen, which is highly flammable, should be vented safely by opening a hot tap
and allowing the water to flow. There should be no smoking or naked flame near the tap
whilst it is turned on. Any hydrogen gas will be dissipated. This is indicated by an unusual
spurting of the water from the tap. Once the water runs freely again, any hydrogen in the
system will have been released. In areas where this is likely to occur, the householder
should be instructed by the installer on how to dissipate the gas safely.
SATURATION INDEX
The saturation index is used as a measure of the water’s corrosive or scaling properties. In
a scaling water supply calcium carbonate is deposited out of the water onto any hot
metallic surface. When water has a saturation index greater than +0.40 an expansion
control valve* must be fitted on the cold water supply after the non-return valve and the
solar collectors should be covered when the water heater is not intended to be used for
extended periods.
Where the saturation index exceeds 0.80, a water softening device and a low watts density
element should be fitted. Where the saturation index is less than –1.0, a corrosion
resistant heating unit should be used (contact your nearest Rheem Service Department or
Accredited Service Agent).
WATER HEATERS NOT INSTALLED IN ACCORDANCE WITH THE ABOVE
ADVICE WILL NOT BE COVERED BY THE RHEEM WARRANTY.
