  • Page 4: Introduction

    It is with the above in mind that we at Solahart Industries Pty Ltd are confident that your purchase of the “STREAMLINE CLOSED CIRCUIT SOLAR PREHEAT” solar water heater will provide you reliable hot water with quality after sales service back up.

  • Page 5: About Your Water Heater

    The solar storage tank is suitable for installation either outdoor or indoor and with either Solahart ‘J’, ‘KF’, ‘LC’, ‘LCS’ or ‘BT’ solar collectors. The system is suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C.
  • Page 6 If the power supply cord or plug to the solar storage tank is damaged, it must be replaced by an authorised person in order to avoid a hazard. The power supply cord and plug must be replaced with a genuine replacement part available from Solahart. Phone your nearest Solahart Dealer to arrange for an inspection.
  • Page 7 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 Solahart water heater is supported by a comprehensive warranty (refer to page 54).

  • Page 8: How Your Water Heater Works

    HOW YOUR WATER HEATER WORKS SOLAR OPERATION The Solahart Streamline closed circuit solar water heater has its vitreous enamel lined solar storage tank installed at ground or floor level, remotely from the solar collectors. This water heater is an indirect solar hot water system with a heat exchanger in the solar storage tank.
  • Page 9 If the power supply to the water heater is on and the green LED is off or the red LED is flashing, this indicates there is a fault with the water heater. The red LED may emit up to five flashes in each series of flashes. Count the number of flashes and phone your nearest Solahart Dealer to arrange for an inspection.

    THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. The system is suitable for installation with Solahart ‘J’, ‘KF’, ‘LC’, ‘LCS’ or ‘BT’ solar collectors. The solar circuit must be installed with a continuous fall of a minimum 5° in the pipe work from the solar...
  • Page 15 INSTALLATION – SOLAR STORAGE TANK 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 16 INSTALLATION – SOLAR STORAGE TANK RAIN WATER TANK If the solar collectors and solar pipe work are to be installed on a section of roof which is part of a rain water runoff collection system, then it is recommended this section of roof and its gutter be isolated from the rain water collection system.
  • Page 17 INSTALLATION – SOLAR STORAGE TANK HOT WATER DELIVERY This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the in-series booster water heater and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding.
  • Page 18 INSTALLATION – SOLAR STORAGE TANK 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 19 INSTALLATION – SOLAR STORAGE TANK REDUCING HEAT LOSSES The cold water line to and the hot water lines 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.

  • Page 22: Installation - Solar Collectors

    INSTALLATION – SOLAR COLLECTORS SOLAR COLLECTOR LOCATION Consideration must be given to the position of the solar collectors in relation to the solar storage tank. There are limitations on both the maximum length of the solar hot and solar cold pipes and the maximum height between the solar storage tank and the solar collectors.
  • Page 23 INSTALLATION – SOLAR COLLECTORS PIPE LENGTHS The solar hot and solar cold pipes between the solar storage tank and the solar collectors shall: • be of DN15 hard drawn copper pipe. • have a continuous fall from the solar collectors to the solar storage tank of a minimum 5° (1 in 10 grade).
  • Page 24 INSTALLATION – SOLAR COLLECTORS Maximum Height To Collectors The solar collectors must be the highest point of the system. The maximum height of the solar installation, from the base of the solar storage tank to the top of the solar collectors, is 9 m. The pump supplied with the solar storage tank will not circulate closed circuit fluid through heights greater than 9 m and solar gain will not be achieved.
  • Page 25 INSTALLATION – SOLAR COLLECTORS WARNING: Plumber – Be Aware • The solar hot and solar cold pipes between the solar storage tank and the solar collectors MUST BE of copper and fully insulated with closed cell polymer insulation or similar (minimum thickness 13 mm).

  • Page 27 CONNECTIONS – PLUMBING RELIEF VALVE The temperature pressure relief valve is shipped behind the lower front cover of the water heater. The temperature 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.
  • Page 28 CONNECTIONS – PLUMBING SOLAR INLET AND OUTLET All pipe work must be cleared of foreign matter before connection and purged before attempting to operate the water heater. All olive compression fittings must use brass or copper olives. Use thread sealing tape or approved thread sealant on all fittings. The solar cold outlet and solar hot inlet connections are located at the top of the solar storage tank.

  • Page 29: Connections - Electrical

    CONNECTIONS – ELECTRICAL The power supply to the water heater must not be switched on until the solar storage tank is filled with water. MEGGER READING It is not mandatory to conduct a megger test on a plug in appliance, however if a megger test is conducted on this water heater, then the following should be noted.
  • Page 30 For reasons of safety and economy, we advise the thermostat of the in-series booster water heater be set at the lowest temperature that will provide sufficient hot water during periods when boosting is required. Solahart recommends the thermostat is set at 60°C to maximise solar contribution. Discuss the thermostat setting requirements with the householder.

  • Page 31: Auxiliary Pump

    AUXILIARY PUMP The solar collectors must be the highest point of the system. The maximum height of the solar installation from the base of the solar storage tank to the top of the solar collectors is 9 m. The pump supplied with the solar storage tank will not circulate closed circuit fluid through heights greater than 9 m and solar gain will not be achieved.
