ABOUT YOUR WATER HEATER WATER HEATER APPLICATION This 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. MODEL TYPE Your Rheem® Premier Loline solar water heater is designed for the solar collectors to be roof mounted and the solar storage tank to be installed at ground or floor level.
ABOUT YOUR WATER HEATER WATER OUTLET TEMPERATURE This water heater has two outlets. One is a hot water outlet and the other is a tempered water outlet. The purpose of the hot water outlet is to deliver hot water at between 60°C and 75°C, usually for kitchen and laundry use. The purpose of the tempered water outlet is to deliver water up to 50°C, usually for bathroom or ensuite use.
ABOUT YOUR WATER HEATER WARNING This water heater is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere with the water heater.
ABOUT YOUR WATER HEATER SOLAR MONITOR The solar storage tank incorporates a solar monitor. The solar monitor is located on the lower front cover and houses both a green and a red LED. The green LED, marked “Solar”, indicates the current operational mode of the solar water heater and the red LED, marked “Attention”, indicates a fault mode. The green LED will emit either a constant glow or a series of flashes, with a 2 second interval between each series.
ABOUT YOUR WATER HEATER FREEZE PROTECTION The water heater has a freeze protection system. The water heater, including the in-series gas booster, is not suitable for installation in areas where the ambient temperature falls below -20°C (including wind chill factor). Refer to “Freeze Protection” on page 22 for further information. PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray.
ABOUT YOUR WATER HEATER GOING ON HOLIDAYS It is not necessary to switch off the electrical supply at the power outlet to the water heater if you are going away. However, if it is necessary to switch off the power to the water heater, refer to “To Turn Off The Water Heater” on page 8. If the power to the water heater is switched off and there is a risk of freezing, then it is necessary to drain the gas booster (refer to “Draining the Gas Booster Water Heater” on page 9).
REGULAR CARE MINOR SIX MONTH MAINTENANCE It is recommended minor maintenance be performed every six months by the dwelling occupant. The minor maintenance includes: Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 11. Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot.
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 page 17).
WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the Rheem warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy. If you are unsure of your water chemistry, you may be able to obtain information from your local water supply authority.
WATER SUPPLIES ANODE INSPECTION AND REPLACEMENT The anodes installed in a vitreous enamel lined steel water heater cylinder will slowly dissipate whilst protecting the cylinder. The life of the cylinder may be extended by replacing the anodes. If the anodes are not replaced during a five year service (refer to “Major Five Year Service” on page 10) then the maximum time after installation when the anodes should be replaced for this water heater is 8 years.
WATER SUPPLIES WITHIN WARRANTY SPECIFICATION -1.0 very corrosive 0 no warranty applies to a: -direct (open circuit) solar collector -continuous flow copper heat exchanger no warranty applies to a: temperature pressure relief valve or a water heater cylinder unless an expansion control valve is fitted. no warranty applies to a: -direct (open circuit) solar collector -continuous flow copper heat exchanger SATURATION INDEX (SI) SOLAR WATER HEATERS - INTEGRATED GAS BOOST (CONTINUOUS FLOW) +0.
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 2.0 L / min.
SAVE A SERVICE CALL GAS BOOSTER OPERATING TOO FREQUENTLY You may find that the gas booster operates more frequently than expected. This will occur when the solar heated water temperature is lower than 58°C, which may be experienced during periods of low solar energy gain or if there has been heavy hot water usage.
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 11).
SAVE A SERVICE CALL HIGHER THAN EXPECTED GAS BILLS With the installation of your new solar hot water system, maximum gas energy savings can be achieved with careful planning of hot water usage. Should you at any time, feel your gas bill is higher than expected, we suggest you check the following points: Is the relief valve running excessively? Refer to “Temperature Pressure Relief Valve Running” on page 17.
