Solar Hiline Water Heater
WARNING: Plumber – Be Aware
Use copper pipe ONLY. Plastic pipe MUST NOT be used.
It is a requirement of a solar water heater installation that all pipe work be in copper
and not plastic, due to the effects of high water temperatures and pressures.
This water heater must be installed and serviced by a qualified person.
Please leave this guide with the householder.

Page 4: About Your Water Heater
Your Rheem solar Hiline™ water heater is designed for both the solar collectors and the solar storage tank to be roof mounted. The solar storage tank has a Colorbond jacket and is suitable for installation with Rheem NPT 200 solar collectors. - Page 5 The solar Hiline water heater is suitable for the heating unit to be connected to either a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an Off-Peak (overnight) electricity supply.
- Page 6 If the electrical conduit to the solar storage tank 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.
- Page 7 ABOUT YOUR WATER HEATER BOOSTER CONTROL An isolating switch is installed in the electrical meter box for the solar storage tank. This should be left switched on to allow the booster heating unit to operate if required. 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 colder months.
- Page 8 ABOUT YOUR WATER HEATER The recommended continuous length of time for boosting is: Booster heating unit size Minimum winter Temperature Model 2.4 kW 3.6 kW 4.8 kW cold water temperature rise Cool / temperate climate 10°C 50°C 2 hours 1 ½ hours 1 hour Temperate / sub tropical climate 15°C...
- Page 9 ABOUT YOUR WATER HEATER 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: Switch off the electrical supply at the isolating switch to the solar storage tank.

Note: The five year service and routine replacement of any components, such as the anode and relief valves, 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. - Page 11 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 5 years, or more frequently in areas where there is a high incidence of water deposits (refer to “Water Supplies”...
- Page 12 REGULAR CARE FLUSHING THE SOLAR COLLECTORS It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted by a person qualified to do so and in the morning within three hours of sunrise, when the water temperature inside the solar collector(s) is lower.

Rheem warranty to apply. ANODE The vitreous enamel lined 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 2500 mg/L and when the correct colour coded anode is used. - Page 14 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. Solar collectors in a direct solar water heater system should be covered when the water heater is not intended to be used for more than two weeks.

11). Collector area is too small For most installations, the number of solar collectors recommended in the Rheem literature has been proven to provide the required solar energy to meet the average family needs. 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. - Page 17 Heavy flows of hot water until the water heater is cold - then stops until water reheats The water heater must be switched off at the isolating switch or switchboard.

The connection, attachment, integration or general association of other equipment or parts which either directly or indirectly affect the operation or performance of this equipment could void the Rheem warranty. All packaging materials must be removed from the solar storage tank prior to its installation. Refer to the warning on page 28 in relation to the removal of the solar collector packaging. - Page 20 INSTALLATION – SOLAR STORAGE TANK 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.
- Page 21 INSTALLATION – SOLAR STORAGE TANK MAINS WATER SUPPLY Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 30).
- Page 22 INSTALLATION – SOLAR STORAGE TANK If a pressure limiting valve is installed on the cold water line to the solar water heater and the cold water line to a temperature limiting device branches off before this valve or from another cold water line in the premises, then a pressure limiting valve of an equal pressure setting may be required prior to the temperature limiting device.
- Page 23 29. ANODE The vitreous enamel lined 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 2500 mg/L and when the correct colour coded anode is used.

INSTALLATION – SOLAR COLLECTORS SOLAR COLLECTOR LOCATION The solar collectors must be installed in a shade free position. The surrounding vicinity should be checked for higher buildings or trees which may cause shade at other times of the year and for small trees which may grow and shade the solar collectors in the future. For optimum performance, the solar collectors should be installed facing towards the equator (i.e. - Page 28 INSTALLATION – SOLAR COLLECTORS LATITUDE OF SOME AUSTRALIAN CITIES Adelaide 35°S Cairns 17°S Hobart 42°S Port Hedland 20°S Alice Springs 24°S Canberra 35°S Mildura 34°S Rockhampton 24°S Brisbane 27°S Darwin 12°S Melbourne 38°S Sydney 34°S Broken Hill 31°S Geraldton 28°S Perth 32°S Townsville...

For reasons of safety and economy, we advise the thermostat be set at the lowest temperature that will provide sufficient hot water during periods when boosting is required. Rheem recommends the thermostat is set at 60°C to maximise solar contribution. Discuss the thermostat setting requirements with the householder. - Page 34 CONNECTIONS – ELECTRICAL The timer control switch should be programmed: to suit the hot water consumption pattern of the household, with the end of the period to coincide with the commencement of the evening hot water usage, to enable a boosting period of not less than the recommended continuous length of time for boosting, for a period when power will be available to the timer.
