INTRODUCTION Congratulations on choosing a “STREAMLINE CLOSED CIRCUIT GAS BOOSTED” solar water heater. We are confident that your purchase will provide you many years of trouble free hot water. All over the world, the Solahart name is synonymous with quality in water heating. From humble beginnings in the pioneering days of Western Australia, a reputation has been built up over nearly a century. In 1905, two enterprising plumbers formed the company known as S. W. Hart, a name tha

ABOUT YOUR WATER HEATER TO TURN ON THE WATER HEATER • Screw in the drain plugs at the cold water inlet and hot water outlet of the gas booster if the gas booster has been drained. • Open the cold water isolation valve fully at the inlet to the water heater. • Open all of the hot water taps in the house (don’t forget the shower). Air will be forced out of the taps. • Close each tap as water flows freely from it. • Open the gas isolation valve fully at the inlet to the water heater. • Plu

ABOUT YOUR WATER HEATER DOES THE WATER QUALITY AFFECT THE WATER HEATER? The water heater is suitable for most public water supplies, however some water qualities may have detrimental effects on the cylinder, gas booster heat exchanger and fittings. If you are in a known harsh water area you must read page 52. If you are not sure, have your water quality checked against the conditions described on page 52. HOW LONG WILL THE WATER HEATER LAST? There are a number of factors that will affec

ABOUT YOUR WATER HEATER DRAINING THE GAS BOOSTER WATER HEATER • Turn off the water heater (refer to “Turn Off The Water Heater” on page 6). • Open a hot tap (preferably the shower outlet). • Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on the underside of the water heater. Water will drain from the water heater. • When water stops flowing from the water heater, close the hot tap. Note: It is recommended not to screw the drain plugs back in, until th

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. The heat exchanger is filled with closed circuit fluid and is connected to the solar collectors forming a closed circuit. As the sun heats the solar collectors,

HOW YOUR WATER HEATER WORKS MAINS PRESSURE The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 19, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved. The supply pressure should be greater than 140 kPa for the rated flow and performance of the gas booster to be achieved. GOI

REGULAR CARE TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume. Continuous leakage of water from the valve and its drain line may indicate a problem with the water heater (refer to “Temperature Pressure Relief Valve Running” on

SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to manufacture or failure of a part. COLD WATER FROM THE HOT TAP • Close the hot tap, wait 10 seconds and open the hot tap again. • Is the hot tap open enough? The gas booster burners will not light if the flow rate is less than 3.0 L / min. • Solar control unit and gas booster not operating Check the power supply cord is plugged i

SAVE A SERVICE CALL • Are you using more hot water than you think? Is one outlet (especially the shower) using more hot water than you think? Very often it is not realised the amount of hot water used, particularly when showering. Carefully review the family’s hot water usage. As you have installed an energy saving appliance, energy saving should also be practised in the home. Adjust your water usage pattern to take advantage of maximum solar gains. Have your plumber install a flow co

SAVE A SERVICE CALL TEMPERATURE PRESSURE RELIEF VALVE RUNNING • Normal Operation It is normal and desirable this valve allows a small quantity of water to escape during the heating cycle. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem. • Continuous dribble Try gently raising the easing lever on the relief valve for a few seconds (refer to “Temperature Pressure Relief Valve” on page 12). This may dislodge a small particle of foreig

SAVE A SERVICE CALL CLOUDS OF WHITE ‘VAPOUR’ FROM THE FLUE TERMINAL During the heating cycle, it is not unusual to see water vapour clouds steaming from the flue terminal, particularly on cold days. This is normal operation of the gas booster. ERROR CODE The water heater provides a diagnostic error code in the event of an interruption to its operation. The error code is displayed on the front of the water heater on the OK MONITOR. If an error code appears: • Close the hot tap and swi
