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 Loline 511 220 water heater is designed for the solar collectors to be roof mounted and the vitreous enamel lined solar storage tank to be installed at ground or floor level, remotely from the solar collectors.
ABOUT YOUR WATER HEATER 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 23, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved. A minimum water supply pressure of 200 kPa is required to enable the solar circulator and solar circuit system to operate effectively.
ABOUT YOUR WATER HEATER SAFETY This water heater is supplied with a thermostat, an over temperature energy cut-out, temperature sensors and a combination temperature pressure relief valve. These devices must not be tampered with or removed. The water heater must not be operated unless each of these devices is fitted and is in working order. The operation of the over-temperature cut-out on the thermostat indicates a possibly dangerous situation.
ABOUT YOUR WATER HEATER FREEZE PROTECTION The system has a level of freeze protection designed to guard the system against damage from freeze conditions. The system must be installed with the full length of the solar hot and solar cold pipes insulated to offer protection against freeze damage (refer to “Pipe Work and Insulation” on page 6). Freeze conditions occur below 6°C.
ABOUT YOUR WATER HEATER SOLAR MONITOR A solar monitor is located on the front of the top 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 BLEEDING THE SOLAR COLLECTORS It is necessary to purge air from the collector circuit: When the water heater 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 pipe work and air has entered the system. If the circulator appears not to be circulating water around the system.
ABOUT YOUR WATER HEATER TO TURN ON THE WATER HEATER Open the cold water isolation valve fully at the inlet to the water heater. If the solar collectors and solar hot and solar cold pipes have been drained, it will be necessary to bleed the collector circuit (refer to “Bleeding the Solar Collectors” on page 9). If the electrical supply to the water heater has been switched off: Switch on the electrical supply at the power outlet to the solar storage tank.
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 12. 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 18).
REGULAR CARE FLUSHING THE SOLAR COLLECTORS It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted in the morning, within three hours of sunrise, when the water temperature inside the solar collectors is lower. Open a hot water tap and allow the water to run for five (5) minutes prior to flushing the solar collectors. Close the hot tap. Wait a further five (5) minutes before attempting to flush the solar collectors.
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 anode 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 anode. If the anode is not replaced during a five year service (refer to “Major Five Year Service” on page 11) then the maximum time after installation when the anode should be replaced is 8 years.
WATER SUPPLIES WITHIN WARRANTY SPECIFICATION -1.0 very corrosive 0 +0.4 no warranty applies to a: -standard watts density heating unit -direct (open circuit) solar collector 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: -copper sheathed heating unit -direct (open circuit) solar collector SATURATION INDEX (SI) SOLAR WATER HEATERS WITH ELECTRIC HEATING UNIT +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. NOT ENOUGH HOT WATER (OR NO HOT WATER) Insufficient sunlight Insufficient sunlight due to cloudy weather during hotter months or low solar energy contribution in colder months may mean the in-series water heater operates more often.
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).
SAVE A SERVICE CALL HIGHER THAN EXPECTED GAS BILLS With the installation of your new solar hot water system, maximum energy savings can be achieved with careful planning of hot water usage. Should you at any time feel your energy account 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 18).
