    Both series transfer heat absorbed from the sun by the solar collectors to the water storage tank through the Natural Thermosiphon Principle without the need for pumps or sensors. The Solahart collectors absorb solar energy. The low-iron content solar glass allows more solar energy to pass through and be retained than conventional glass.

  • Page 4: Facts You Should Know About Your Solahart Water Heater

    Hot Hot Water! Your Solahart water heater will generate hot water quickly and efficiently. Under normal family use, it will operate between 60ºC and 70ºC. However, the temperature can exceed this and under certain circumstances may be as high as 95ºC (see recommendation below).
  • Page 5 Water Quality - Is It Suitable For The Solahart Water Heater? Your Solahart water heater is suitable for use with water with a total dissolved solid content less than 1,000 ppm and for which the total hardness does not exceed 200 ppm CaCO 3 . Water supplies having calcium hardness (CaCO 3 ) and an alkalinity in excess of 150 ppm should be treated by a softening process prior to use with this water heater to prevent scaling and damage to the electric booster element.

    200 litres The overall performance and energy savings that you will obtain from your Solahart water heater will depend on your hot water usage pattern and your operation of the in-tank booster. A time clock may be fitted to the system to turn the booster on when required.
  • Page 7 33-1197 Solahart Owner‟s Manual – Thermosiphon Systems - Revision F – Jan. 12 Timer Control of the Tank Boosting A timer control switch can be installed and will help maximise energy savings with an electrically boosted solar water heater connected to a continuous, time of use or extended Off-Peak (overnight and day) electricity supply.

    THE DRAIN LINE WILL BE HOT. STAND CLEAR OF THE DRAIN LINE‟S POINT OF DISCHARGE WHEN OPERATING THE VALVE‟S LEVER. If the temperature pressure relief valve is not readily accessible, contact your local Solahart Dealer. Operate the easing lever on the expansion control valve. It is very important you raise and lower the lever gently.
  • Page 11 Operate the easing lever on the expansion control valve once every six months. If water does not flow freely from the drain line when the lever is lifted, then the water heater should be checked by your nearest Solahart Dealer. The expansion control valve should be checked for performance or replaced at intervals not exceeding 5 years, or more frequently in areas where there is a high incidence of water deposits.

    In areas susceptible to cyclones, hurricanes or very high winds, a suitable With Pitch frame is required. Refer to your local Solahart Dealer for details. The installation of this solar water heater on a suitable frame, subject to the frame‟s design...
  • Page 13 / freezing, a Closed Circuit system should be used. Solahart recommends using a minimum of 1 complete 4.5 litre bottle of „Hartgard‟ in each system (or a minimum concentration of 20% in large capacity systems) as standard where ambient temperatures do not fall below 0°C.

    OR DAMAGE TO THE HEATING ELEMENT WILL RESULT The power rating and current requirement of your Solahart water heater will be specified on the heater‟s data plate, located on the cover to the electrical cavity. The temperature rating of the power supply lead‟s insulation should suit this application.
  • Page 15 A combination thermostat/safety cut-out is installed to control the electrical heating element to the factory pre-set temperature of 60°C. Individual situations may require this setting to be altered. Only qualified electricians or Solahart service contractors are permitted to adjust the thermostat. The safety cut-out (also called a thermal cut-out) will de-energise the element should the temperature within the tank reach 83°C when the element is activated.
  • Page 16 Local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to the water heater. In other areas, an ECV is not required unless the water saturation index is greater than +0.4. For this Solahart Water Heater an RMC H50 Cold Relief Valve (part no 45-1103) is supplied in the parts kit for use as the ECV.
  • Page 17 Manually fed boosters such as stove coils, back boilers or coils in open fired grates are not permitted to be connected to Solahart water heaters unless the storage cylinder is open vented. Such auxiliary energy sources must not be connected into the closed circuit.
  • Page 18 33-1197 Solahart Owner‟s Manual – Thermosiphon Systems - Revision F – Jan. 12 Thermosiphon Pipe Shroud Cover The function of the Pipe Shroud Cover is to cover the plumbing pipe-work and electrical connections to the thermosiphon tank, including the drain line from the temperature pressure relief valve, without restricting pipe runs for the installation or the operation of the TPR valve.
  • Page 19 33-1197 Solahart Owner‟s Manual – Thermosiphon Systems - Revision F – Jan. 12 FITTING THE PIPE SHROUD COVER The Pipe Shroud Cover contains a number of preformed cut outs. Each cut-out can be removed using a pair of snips by following the preformed cut-out lines.

    33-1197 Solahart Owner‟s Manual – Thermosiphon Systems - Revision F – Jan. 12 INSTALLATION INSTRUCTIONS – CLOSED CIRCUIT SERIES WARNING: THE TANKS AND COLLECTORS ARE HEAVY. IMPROPER LIFTING TECHNIQUES COULD RESULT IN PERSONAL INJURY DURING INSTALLATION. IT IS THE INSTALLER‟S RESPONSIBILITY TO USE ONLY APPROVED LIFTING AND SAFETY DEVICES AND TECHNIQUES WHEN LIFTING COLLECTORS AND TANKS ON ROOFS.

  • Page 21: Filling And Commissioning The Closed Circuit

    In locations frequently subject to atmospheric temperature below -10ºC, hot and cold pipes and valves may freeze even when insulated. It is recommended that in these locations, the cold pipes and valves to the Solahart storage tank and the hot pipe from the tank should have electric heater tape under the insulation.
  • Page 22 If this is the case, then the section of gutter immediately beneath the proposed location of the new Solahart system should be isolated from the rainwater collection system. This can be done by blocking that section of gutter from the remaining gutter, and fitting a separate down pipe to take any run-off water from that section of roof away to waste.
