IMPORTANT INFORMATION & WARNINGS SAFETY & REGULATORY INFORMATION DO NOT operate this system before reading the manufacturers instructions. WARNING This appliance must be installed, commissioned and serviced by an authorised person in accordance with all applicable local rules and regulations. Access covers of water heating system components will expose 240V wiring and MUST be removed by an authorised person.
IMPORTANT INFORMATION & WARNINGS SCALDS HAZARDS HOT WATER CAN CAUSE SCALDS. CHILDREN, DISABLED, ELDERLY AND THE INFIRM ARE AT THE HIGHEST RISK OF BEING SCALDED. FEEL WATER TEMPERATURE BEFORE BATHING OR SHOWERING. SCALDS FROM HOT WATER TAPS CAN RESULT IN SEVERE INJURIES TO YOUNG CHILDREN. SCALDS OCCUR WHEN CHILDREN ARE EXPOSED DIRECTLY TO HOT WATER WHEN THEY ARE PLACED INTO A BATH WHICH IS TOO HOT. ALWAYS......
IMPORTANT INFORMATION & WARNINGS OPERATION PRINCIPLE This system is designed to have the solar collectors on the roof and the storage cylinder installed at ground or floor level.Electric and Gas boosted models are available. The system comprises a hot water storage cylinder, solar collectors, pump circulation system solar control unit and temperature sensors.
IMPORTANT INFORMATION & WARNINGS SAFETY DEVICES The water heating system is supplied with various safety devices including temperature sensors, overheat sensors and switches and a Pressure & Temperature Relief (PTR) valve. These devices must not be tampered with or removed. The water heating system must not be operated unless each of these devices is fitted and is in working order. DO NOT tamper with or remove safety devices.
IMPORTANT INFORMATION & WARNINGS Gas boosted models • Do not touch the flue outlet or do not insert any objects into the flue outlet. • Keep flammable materials, spray cans, fuel containers, trees, shrubs and pool chemicals etc. well clear of the flue outlet. • Do not use the gas types other than those designated on the data plate. For example, do not use Propane/Butane gas mixtures on appliances marked Propane Gas. • Do not use Propane gas on appliances marked as Natural gas and vice versa.
IMPORTANT INFORMATION & WARNINGS WATER QUALITY The water quality of most public supplies is suitable for the water heating system. The water quality from bore wells is generally unsuitable for the water heating system. Refer to separate 'Warranty Terms and Conditions' document for water quality parameters and how they affect the warranty conditions. If in doubt about the water quality, have it checked against the parameters listed in the warranty conditions.
SAVE A SERVICE CALL Table 1 - Troubleshooting Problem Insufficient or no hot Water Cause Remedy Booster heating not operating Or Insufficient gas supply for gas boosted heating system Excessive hot water consumption Electric Boosted Systems: If the water goes cold, are you using more hot water than you think? Often end users are surprised at the amount of hot water used, especially when showering.
SAVE A SERVICE CALL Problem Cause Remedy Insufficient or no hot Water continued Booster element Thermostat Settings Electric Boosted Systems: The end user can check the temperature of hot water delivered with a thermometer placed under the closest non tempered outlet (usually the kitchen sink). CAUTION: Take care to avoid scalding. This test should be done early in the morning after overnight electrical boosting before any hot water is used.
SPECIFICATIONS FOR SYSTEMS GENERAL Split solar hot water systems are specified according to the grade of storage cylinder material, cylinder capacity, number of solar collectors and boost type and capacity. Boost capacity for gas boosted system depends on the gas booster model selected. Boost capacity for electrically boosted systems depends on the power rating of electric heating elements and whether one or two electric heating elements are fitted.

INSTALLATION & MAINTENANCE - ALL SYSTEMS REGULATIONS AND OCCUPATIONAL HEALTH AND SAFETY (OH&S) WARNING Installation and commissioning must be performed by authorised persons. Solar systems must be installed in accordance with these instructions and all regulatory requirements which exist in your area including those in relation to manual lifting, working at heights and on roofs.
INSTALLATION & MAINTENANCE - ALL SYSTEMS GAS BOOSTER LOCATION AND MOUNTING (where applicable) The gas booster is designed for 'Outdoor' Installation only. As such, it must be located in an above ground open air situation with natural ventilation, without stagnant areas, where gas leakage and products of combustion are rapidly dispersed by wind and natural convection.
INSTALLATION & MAINTENANCE - ALL SYSTEMS VALVES & FITTINGS The following valves and fittings are supplied with your solar hot water system: • A combined pressure and temperature (PTR) relief valve, capacity 10 kW. Relief valve pressure settings vary with models. This valve is fitted at the top of the storage cylinder. The PTR valve is a safety device and it is mandatory that it is fitted by the installer in all installations.

INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS INSTALLATION PROCEDURE Install Solar Collectors Position and install the solar collectors in accordance with the section ‘INSTALLATION SOLAR COLLECTORS”. 1. Position Storage Cylinder Position the hot water storage cylinder on a level base in accordance with the section ‘STORAGE CYLINDER LOCATION’. 2. Connect PTR Valve • Connect the PTR Valve in the location shown in the relevant diagram of Figures 27 to 30. Leave the valve outlet pointing down.
INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS 7. Cold Water Supply • Connect cold water supply to the inlet ‘T’. Ensure that the relevant valves as described in the section “VALVES AND FITTINGS” are fitted. • Purge the cold water supply lines to remove air and swarf before final connection. 8. Relief Drain Lines • Independent 15 mm copper pipes must be fitted to the drain outlets of the PTR and ECV.
INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS CHECKING SOLAR PUMP OPERATION 1. Ensure hot and cold sensors are connected as shown Figure 31. 2. Activate power supply. 3. Pumps will operate when solar energy is available to be collected. Pump operation can be checked by placing the end of a screw driver to the pump body and the other end of the screw driver near your ear. The dip switches within the pump control box should not need to be adjusted.
INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS PRE SOLAR HEATING CHECKS Before commencing solar heating of the water in the system ensure the following actions have been completed: Solar Collectors 1. Are the solar collectors installed with the correct slope and orientation to the sun? 2. Is the installation finished neatly with the roof made good, all tiles and flashings in place? 3. Are the bolts tight on the roof framework? 4.
INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS Temperature Limiting Devices 1. Commission any temperature limiting devices in accordance with the instructions supplied by the manufacturer. 2. Confirm the hot water delivery temperature at a tempered water outlet. Tempered water outlets should be those supplying areas primarily used for the purposes of personal hygiene such as bathrooms.
