  • Page 4: About Your Solar Water Heater

    ABOUT YOUR SOLAR WATER HEATER Product Application This solar 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. Warning: This solar water heater is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so.
  • Page 5: Pipe Work, Insulation & Freeze Protection

    Gas Booster Operation During periods of low solar energy (low solar gain), the gas booster will boost the water temperature automatically to its preset outlet temperature setting (refer to “Hot Water Temperature” on page 4). Mains Pressure Operation This solar water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
  • Page 6: Turning On The Solar Water Heater

    It is essential the electrical circuit to the solar control unit is continually turned on if there is a risk of freezing. The Aquamax warranty does not cover damage caused by freeze conditions when the electrical circuit or electrical supply to the solar control unit is turned off or interrupted. Warning: If it is necessary to switch the power off to the solar control unit and there is a risk of freezing, then it is necessary to have your plumber drain the solar collectors and solar flow and return pipe work.
  • Page 7: Periodic Maintenance

    If it is necessary to turn off the solar water heater for any reason, follow the “Shut Down Procedure” on page Note: When switched back on, the solar water heater will take some time to reheat the water by solar gain. The time to reheat the water in the solar storage cylinder will depend upon time of year, time of day and prevailing weather conditions;...

If a safety tray is installed, check to ensure the safety tray drain pipe is not blocked. Clean solar collector glass if required (refer to “Cleaning the Solar Collector Glass” on page 8). Major Five Year Service It is recommended a major five year service be conducted on the solar water heater including the gas booster (for gas booster major five year service actions, refer to the Owner‟s Guide and Installation...
  • Page 9 Expansion Control Valve (ECV) In many areas, including South Australia, Western Australia and scaling water areas, an ECV is fitted to the cold water supply line to the solar water heater (refer to the “Cold Water Supply Plumbing Arrangement” diagram on page 21). The ECV may discharge a small quantity of water from its drain line during the heating period instead of the PTR valve on the solar water heater.

    Purging the Solar Collectors It is necessary to purge air from the solar collector circuit: After installation. When the solar system is to be turned on and the solar collectors and solar hot and solar cold pipes have been drained. After maintenance has been conducted on the solar collectors or pipe work and air has entered the system.

    INSTALLATION Installation Overview This solar water heater must be installed by a qualified person in accordance with the installation instructions. The installation must comply with the requirements of AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. This solar water heater is comprised of the following components: Solar storage cylinder.
  • Page 16: Water Supplies

    Hot Water Redundancy If this solar 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. This should ensure the continuity of hot water supply in the event that this solar water heater was to become inoperable for any reason.

    INSTALLATION – COMPONENTS This section details the installation of the solar storage cylinder, gas booster, solar controller kit and solar collector kit. To install the plumbing for these components refer to the “Installation – Plumbing & Plumbing Connections” section on page 20. Solar Storage Cylinder Installation Solar Storage Cylinder Location The solar storage cylinder is suitable for either outdoor or indoor installation, however if the gas booster is...
  • Page 18: Gas Booster Installation

    Gas Booster Installation Gas Booster Location The gas booster must not be installed indoors or in a confined space. The gas booster may be remotely located or mounted on the solar storage cylinder. If the gas booster is mounted on the solar storage cylinder, the solar water heater is suitable for outdoor installation only.
  • Page 19: Solar Controller Kit Installation

    Mounting the Gas Booster to the Solar Storage Cylinder A mounting bracket has been installed on the solar storage cylinder to support the gas booster. To mount an Aquamax CF20-60 or CF26-60 model continuous flow in-series gas booster to the storage cylinder: Remove two screws retaining gas booster top bracket (located on rear of gas booster) and remove bracket.
  • Page 20 For optimum performance, inclination of solar collectors should be approximately equal to 90% of the local latitude angle. The latitudes of some Australian cities are shown in the “Latitude of Some Australian Cities Table” on page 19. Solar collectors may be installed at the roof angle for simplicity of installation and appearance, but must never be flat.
