Electric 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.

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. - Page 2 Failure of plastic pipe can lead to the release of high temperature water and cause severe water damage and flooding. Refer to Warning on page 29. This water heater may be protected by one or more patents or registered designs in the PATENTS name of Rheem Australia Pty Ltd.

Page 4: About Your Water Heater
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. - Page 5 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 50°C at the bathroom and ensuite.
- Page 6 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).
- Page 7 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.
- Page 8 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 Collectors” on page 7, allowing the water to flow from the bleed valve drain line for five minutes before closing the bleed valve.
-
Page 9: Regular Care
If water does not flow freely from the drain line when the lever is lifted, then the water heater should be checked by the Rheem Service Department of their Accredited Service Agent. -
Page 10: How Your Water Heater Works
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. - Page 11 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.
- Page 12 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.
- Page 13 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.

· 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. - Page 15 · Water heater size Do you have the correct size water heater for your requirements? The sizing guides in the sales literature and on the Rheem website (www.rheem.com.au) 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.
- Page 16 EXPANSION CONTROL VALVE RUNNING If an expansion control valve is fitted in the cold water line to the water heater (refer to page 21) it may discharge a small quantity of water instead of the Temperature and Pressure Relief valve on the water heater.
- Page 17 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.

Clearance must be allowed for servicing of the water heater. The solar water heater storage tank must be accessible without the use of a ladder or scaffold. Make sure the Temperature and Pressure Relief valve lever is accessible and the front cover, thermostat and booster heating unit can be removed for service. - Page 19 * Expansion control valve not supplied with the water heater. TANK WATER SUPPLY If the water heater is supplied with water from a tank supply, then the bottom of the supply tank must be at least 1 m above both the solar collectors and the highest hot water outlet.
- Page 20 We recommend the first 1.5 to 2 m of the hot water line coming out of the water heater be insulated with weatherproof insulation. In addition, the insulation of the hot water line from the water heater must comply with the requirements of AS/NZS 3400.4.2.
- Page 21 INSTALLATION – SOLAR STORAGE TANK ASSEMBLY OF COLD WATER SUPPLY AND SOLAR PIPE CONNECTIONS Use thread sealing tape or approved thread sealant on all fittings. All compression fittings must use brass or copper olives. Ensure the air bleed valve is open when filling collectors. HOT WATER OUTLET Provide a union for disconnection.

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. - Page 29 CONNECTIONS - PLUMBING WARNING: Plumber – Be Aware: · 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). ·...
- Page 30 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,...
- Page 31 CONNECTIONS - PLUMBING 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 page 38).

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 65°C. - Page 33 OPERATION The active from the continuous electricity supply must be connected to the top heating unit circuit and the active from the Off-Peak electricity supply must be connected to the bottom heating unit circuit for the water heater to operate.

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. - Page 35 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: · Close the cold water isolation valve at the inlet to the water heater.

Page 36: Draining The Solar Collectors
To drain the solar collectors and the solar hot and cold pipe: · Turn off the water heater (refer to “To Turn Off the Water Heater” on page 35). · Using a flat bladed screw driver, open the bleed valve fitted adjacent to the 5 way tee at the cold water inlet of the water heater (refer to diagram on page 34). -

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. -
