70°C. Automatic safety controls are fitted to the water heater to provide safe and efficient operation. 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 18, a pressure limiting valve must be fitted.
Page 10 The “One Shot Control” switch will help provide maximum savings with an electrically boosted solar water heater connected to a continuous electricity supply. Power must be available to the “One Shot Control” switch before the booster heating unit can be activated.
Page 11 HOW YOUR WATER HEATER WORKS GOING ON HOLIDAYS If you plan to be away from home, 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...
Page 12: Regular Care
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.
Page 13 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 in the morning, within three hours of sunrise. • Open a hot water tap and allow the water to run for five (5) minutes prior to flushing the solar collector(s).

If on an Off-Peak or time controlled supply, remember heating hours are restricted (refer to Tariff” on page 10). Check the fuse marked “HOT WATER” or “WATER HEATER” at the switchboard. • Solar Control Unit Check the power outlet for the solar control unit is switched on.
Page 15 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 guides in the sales literature and on the Solahart website 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 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.
Page 17: Installation - Solar Storage Tank
Remember all local authorities have regulations about putting water heaters into roof spaces. SAFE TRAY It is a requirement of AS/NZS 3500.4 that for a new installation, a water heater be installed in a safe tray where in the event of a leak, property may otherwise be damaged. Construction, installation and draining of a safe tray must comply with the above mentioned Standard.
Page 18 * 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 a pressure pump system is recommended to ensure a minimum water pressure of 200 kPa is achieved to allow the solar circuit system to operate.
Page 19 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 20 CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A solar water heater should not be installed as part of a circulated hot water flow and return system in a building. The benefits of solar gain will be significantly reduced and energy gained from the sun lost through the pipe work.
Page 21 INSTALLATION – SOLAR STORAGE TANK REDUCING HEAT LOSSES The cold water line to and the hot water line from the water heater must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed.

All olive compression fittings must use brass or copper olives. Use thread sealing tape or approved thread sealant on all fittings. An isolation valve and non return valve must be installed on the cold water line to the water heater. Use the arrangement shown in the diagram. Refer also to The plumbing arrangements for the cold water inlet and solar hot and solar cold pipes are shown on page 25.
Page 29 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 line must be in such a position that flow out of the pipe can be easily seen (refer to AS/NZS 3500.4) - but arranged so hot water discharge will not cause injury, damage or nuisance.
Page 30 BLEED VALVE DRAIN A copper drain line 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.
