Page 5: 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 6 Electric Booster Operation The electric booster is an electric immersion heating unit (element) which is located behind the front access cover of the solar storage cylinder. Water stored in the solar storage cylinder is heated by the electric booster at times of low solar energy (low solar gain), such as during very cloudy or rainy weather, or during the colder months of the year.

Page 8: Other Important Information
During periods of low solar energy gain, the water temperature in the solar storage cylinder will be automatically boosted by the thermostatically controlled electric booster (refer to ‘Electric Booster Operation’ on page 5). The booster thermostat setting can be set by a qualified person to a minimum of 60° C and a maximum of 70°... -
Page 9: Periodic Maintenance
How Long Will the Water Heater Last? The solar water heater is supported by a manufacturer’s warranty (refer to page 38). There are a number of factors that will affect the length of service the solar water heater will provide. These include but are not limited to the water chemistry, the water pressure, the water temperature (inlet and outlet) and the water usage pattern. - Page 10 prevailing weather conditions; however, the electric booster will provide a quantity of hot water after a period of 2 ~ 6 hours (boost quantity and time dependent upon solar storage cylinder size). Pressure Temperature Relief Valve (PTR Valve) The PTR valve is near the top of the solar storage cylinder and is essential for safe operation. It is possible for the PTR valve to release a little water through the drain line during each heating period.
- Page 11 Flushing the Solar Collectors It may be necessary to flush the solar collectors if there is sediment in the water supply. It is recommended that the solar collectors are flushed every five years. This will assist in keeping the solar collectors, solar cold pipe and solar hot pipe clear of sediment (refer to ‘Major Five Year Service’...

Page 12: Water Chemistry
Change of Water Supply The changing or alternating from one water supply to another can have a detrimental effect on the operation and / or life expectation of the solar storage cylinder and pressure temperature relief valve. Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water supply, desalinated water supply, public reticulated water supply or water brought in from another supply, then water chemistry information should be sought from the supplier or it should be tested to ensure the water supply meets the requirements given in these guidelines for the Aquamax warranty to apply. -

In a corrosive water supply, water can attack copper parts and cause them to fail. - Page 14 If the Solar Monitor green LED is off, or the red LED is flashing, switch off the electrical supply at the power outlet to the solar control unit for five (5) seconds and then switch back on again. If the green LED remains off or the red LED recommences to flash, count the number of flashes and phone Aquamax Service or their nearest Accredited Service Agent to arrange for an inspection.

Expansion Control Valve Running If an expansion control valve is fitted in the cold water line to the solar water heater, it may discharge a small quantity of water instead of the solar water heaters pressure temperature relief valve. This has the benefit of conserving energy as the discharged water is cooler (refer to the ‘Cold Water Supply Plumbing Arrangement’... - Page 16 The green LED will emit either a constant glow or a series of flashes, with a 2 second interval between each series. The red LED will emit a series of flashes, with a 2 second interval between each series, only if there is a particular fault condition with 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 with integral electric booster. -
Page 18: 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, solar controller kit and solar collector kit. To install the plumbing for these components refer to the ‘Installation – Plumbing & Plumbing Connections’ section on page 21. Solar Storage Cylinder Installation Solar Storage Cylinder Location The solar storage cylinder is suitable for either outdoor or indoor installation. -
Page 20: Solar Collector Kit Installation
The solar control unit is mounted on the side of the solar storage cylinder and controls system operation. The solar control unit has a power cord which connects to a 240 volt general purpose outlet (refer to ‘Installation – Electrical & Electrical Connections’ on page 29). The solar control unit incorporates a circulating pump which when energised circulates water from the solar storage cylinder through the collector circuit and back to the solar storage cylinder. - Page 21 Latitude of Some Australian Cities Adelaide 35°S Cairns 17°S Hobart 42°S Port Hedland 20°S Alice Springs 24°S Canberra 35°S Mildura 34°S Rockhampton 24°S Brisbane 27°S Darwin 12°S Melbourne 38°S Sydney 34°S Broken Hill 31°S Geraldton 28°S Perth 32°S Townsville 19°S Refer to the installation instructions supplied with the solar collector kit for details on the installation of the solar collector kit.

work from the bleed valve to the drain should be as short as possible and must have continuous fall from the valve to the drain with no restrictions. The drain line must have no more than three right angle bends. The outlet of a drain line must be in such a position that flow out of the pipe can be easily seen, but arranged so that discharge will not cause injury, damage, nuisance or splashing. - Page 26 The maximum recommended total pipe length of the solar circuit should not be exceeded and a minimum water supply pressure of 200 kPa should be available at the inlet to the solar water heater, otherwise system performance may be reduced or the solar circuit may not be purged of air during commissioning of the solar water heater.
