GENERAL This instruction is the manual for installation and use of Solar Lord water Heaters. It states how to install, set‐ up and check the system. It also provides necessary technical data and knowledge of solar hot water system. THE PRINCIPAL OF OPERATION Since evacuated glass tube technology was inverted, solar energy can be changed to heat energy efficiently in four seasons. Solar exposure can be turned to heat regardless ambient temperature of the collectors. Solar Lord collectors using German design for the tubing and Sydney University coating technology for the absorbing surface. inside and outside tubes are made from extremely strong borosilicate glass which are evacuated and fused together. The vacuum space between two glass layers forms excellent insulation to stop the heat loss from the inside to the outside. The outside of the inner tube is coated a surface to absorb maximum solar en‐ ergy. When sunlight strikes the collector, the solar radiation goes through the clear glass of the outside tubes and is absorbed by the coating on the outside of the inner tubes. The solar energy is changed into heat energy by the coating surface and heats the inner tube. Either a heat‐transfer fluid or the actual potable water to be used flows through tubes attached to the ab‐ sorber and transfers the heat from it. The heated water is stored in a storage tank until needed. If additional heat is needed, it is provided by electricity or gas energy. The Solar Lord hot water system you are installing is a ‘pump’ solar system that has circulation of water (direct loop) or glycol mixture (indirect loop) around the solar collector. The small circulating pump circulates the water between the collectors and the hot water cylinder. The pump is usually operated by a solar controller that only turns the pump on when the water in the collector is warmer than the water in the tank. These pumps are very quiet, offering no noise disturbance and only draw around 23 watts. We can also offer 12 volt pumps which are coupled to a photovoltaic cell of approximately up to 20 watts de‐ pending upon system characteristics. These systems offer automatic control, i.e. when there is solar gain, the collector warms up and also the pump operates. These systems are often installed in remote sites where thermosyphon systems are not suitable. In a Heat Pipe collector, the Sun’s energy that is absorbed by the tubes is then transferred to your water via ...

The result is an incredibly efficient system to harness the heat of the Sun even in extremely cold areas. Be‐ cause the system is so efficient it does not require full sun and can work in cloudy or even rainy days. Heat Pipe Inside of the copper heat pipe has been evacuated and filled with not‐toxic heat transfer liquid. When sun rays strike the evacuated tube, the liquid will be heated and melt to a hot vapour. The hot vapour rises up to con‐ denser at top of the heat pipe and heats up the manifold where the heat pipe is plugged in. When water flows through inside of the manifold, the water is heated and flows into storage tank. Once the vapour release the heat to manifold it turns into liquid again, then flows down to the base of the heat pipe. This cycle continu‐ ously repeats when solar radiation is being absorbed by the heat pipe. Every circulation of liquid‐gas will com‐ plete the heat transfer. In this way the solar energy is transferred from the heat pipe to the manifold where the cold water is heated. During the day, water is circulated through the manifold header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5‐10°C. Throughout the day, the water in the storage tank is gradually heated. The evacuated tubular collector with heat pipes can be quasi‐tracking in four seasons, the collector will be in operation as long as the sun shines. Within the heat pipe collector the heat transfers is in one direction only. Heat pipe water heaters can be in service all year round even in cold climate areas where experience below to ‐9°C in winter. Copper U Tube The inside and outside tubes are made from extremely strong borosilicate glass which are evacuated and fused together. The vacuum space between two glass layers forms excellent insulation to stop the heat loss from inside to the outside. The outside of the inner tube is coated with the “Novel Sputtering” coating to absorb maximum solar energy. This coating was developed and patented at Sydney University. ...

The copper tube is bent into a U Shape (called U tube) and inlaid into heat transferring fins. Both copper tubes and a pair of fins sit inside of the evacuated glass tube. When sunlight strikes the collector the solar radiation goes through the clear glass of the outside tubes is absorbed by the coating on the outside of the inner tubes. The solar energy is changed into heat energy by the coating surface and heats the inner tube. Encircled by the inner glass tube the fins transfer the heat from the absorbing surface of the inner tube to the copper U tube. Water flows inside the U copper tube and is heated and piped to the storage tank where it is kept until needed. The U tube collectors maximize solar heat gain and minimize heat loss. It has been tested and proven to be the highest efficiency collector available globally. The testing was performed by German laboratory Fraunhofer ‐ the top laboratory of solar energy in the world. DIRECT HEATING SYSTEM (OPEN LOOP): E450U45‐O, E450U30‐O, E340U15‐O, E270U15‐O, E450SH48‐O, E450SH40‐O, E340SH32‐O, E270SH24‐O & E180SH16 G450U45‐O, G450U30‐O, G340U15‐O and G270U15‐O, G450SH48‐O, G450SH40‐O, G340SH32‐O, G270SH24‐O, G2001‐O and G180SH16‐O In the open loop system the potable water is directly heated as it circulates by a pump through solar collectors mounted on the roof. The heated water is then stored in a ground‐mounted storage cylinder and rises up the cylinder by natural convection to the top of the tank where the hot let is. INDIRECT HEATING SYSTEM (CLOSED LOOP): E3002‐C, E3001‐C, G3002‐C & G3002‐C Indirect heating systems use a heat exchanger in the storage tank to complete heat transfer. By using an indi‐ rect solar circuit that contains a glycol mixture circulated to solar collectors by a pump, the heat energy pro‐ duced from the absorbing surface of the collector is transferred to the potable water in the storage tank as the glycol passes through the heat exchanger. The indirect (closed) circuit protects the collectors from freezing and is recommended for areas that are susceptible to frost below ‐7°C or harsh water conditions. An auxiliary heater is also included in the system to boost water temperature during periods of continuous rain or low sun radiation days. Boosters may run on continuous/off‐peak electricity or post gas. The system model represents source of booster, storage capacity, type of collector, number of evacuated glass tubes and kind of system indicated in order as follows, ...
CONTRACTOR’S RESPONSIBILITIES 1. STANDARDS All Solar Lord Hot Water systems must be installed by an authorised Plumber and electricity supplied by a reg‐ istered electrician. The entire works will need to meet local authority standards, Australia Standard (AS 3500.4) and the National Plumbing Code along with local Electrical regulations. 2. PREPARATIONS (a) Installers must have been completely trained in the correct safety procedures for working at heights of roofs and make sure that all work is carried out in accordance with local, state and federal occupational safety, health and welfare regulations in particular the requirements for safety whilst manual lifting, working at heights and on roofs. (b) Use an approved lifting device as the solar tanks and collectors can be very heavy (ref to specification). The evacuated glass tubes are fragile. Take care when lifting and installing the collector(s). Wear gloves to avoid cut by broken glass and scalded hot components. (c) Take all considerations to protect and warn occupants of the building and the public from personal injury which may occur from falling tools, broken glass, roof materials, fittings or any other hazards of a general na‐ ture. (d) Advise the occupants of the property about any inconvenience cause by temperate disconnection of exist‐ ing water, electrical and gas supplies during the installation. 3. COMMISSIONING The commissioning of the installation and its handing over to the client shall be the responsibility of the con‐ tractor. The contractor shall instruct in the method operation and hand the client a copy of this manual. It is the contractor’s responsibility to advise owners of the potential hazard scalding in accordance with AS3500.4 and other related standards. Call the client and check if system functions well and supplies enough hot water three days after the installa‐ tion. ...
INSTALLATION SYSTEM LOCATION Solar collectors Orientation The solar collector must be mounted on the roof and orientated to geographic north for optimum solar gain. Geographic north is between 17 and 24 degrees west of magnetic north as shown by a compass. For optimum performance, the solar collector/s should be positioned on a north‐facing roof (no more than 45° east or west of north) at an angle between 15° and 50°. Use a compass to check orientation. Variation greater than 60°East/West will require an additional collector, while between 45°‐ 60° can be acceptable under certain cir‐ cumstances of less than average hot water usage The collector should be in a shadow free position all year round. Carefully check for high buildings or trees in the vicinity for WINTER shade. A deviation of 45° to east/west has little effect on annual solar gain. Inclination Inclination of the solar collector should be approximately equal to the local latitude angle for receiving max annual solar gain. If the roof angle varies by ±15° from the correct angle, annual efficiency will be reduced by . 5%. In general variation about ±10° is acceptable Traditional flat collectors request the ideal inclination of the solar collector at an angle equal to the latitude of the site due to its significant loss on the annual solar gains if collector deviations greater than20 °. Solar Lord U tube Collector can be installed on any roof pitch from 10° ‐ 90° due to its high efficiency. Solar Lord Heat Pipe collector needs a roof pitch greater than 20° to achieve the best performance. Standard roof pitch is usually sufficient. An inclination less than the latitude will result in increased summer performance and inclinations greater than the latitude of the site will increase solar gain during winter. Because the lowest Sun rays, shortest sunshine duration and coldest water temperature from the mains in winter, we encourage you to install collectors incli‐ nation as high as possible to capture max solar energy in winter. The latitudes of the main cities of Australia ; are listed below CITY LATITUTE CITY LATITUTE CITY LATITUTE CITY LATITUTE Adelaide ...
weight and size (refer to SOLAR COLLECTOR LOCATION PG.17). The building shall be complied with national building regulations and associated Australian Standards or equivalent. It is the installer’s responsibility to en‐ sure that the necessary structural assessments have been made. Special condition areas a) CYCLONIC AREAS The cylindrical shape of the evacuated glass tubes and the gaps between the tubes let wind easily get through. The collector/s can stand up to Beaufort Wind Force 11. Solar Lord mounting frame has com‐ pleted the test and past to the test of Australia Standards (AS 4040.03:1992 and AS 1170.2:2002). This test includes the collector and installation kids for Wind Resistance. It is strongly recommended that the sys‐ tem is fitted onto the mounting frame and to be secured and fastened enough to resist these conditions. b) FROST AND POOR WATER QUALITY AREAS (E3001‐C, E3002‐C, G3001‐C & G3002‐C) The Closed Loop (indirect circuit) should apply to these areas. The closed solar circuit system is designed for frost‐prone and poor quality areas. Anti‐freeze control is incorporated in the design by using a glycol mixture in the solar circuit. The heat transfer fluid is ’Glycol’ which has specific properties that prevent it from freezing and therefore eliminating the risk of frost damage to the collectors. Solar Lord Glycol is a food‐grade fluid. De‐ pending upon its concentration, it enables the system to operate at environment temperatures down to ‐40°C. Please contact Solar Lord for further details. Storage Tank To obtain maximum performance the solar tank should be positioned as close as possible to the most used outlets and to solar collectors as well. The tank can be installed internally on an approved spill tray with drain or externally on a level concrete plinth. Make sure Pressure and Temperature Relief valve is accessible. It is recommended the solar storage tank be installed at ground or floor level and shall be placed vertical upright. No blockage above the tank and electric element bush (electric back up models) for easy access for maintain and service purposes. Boosting Systems that use electrical boosting should be connected to day tariff (power) or off peak tariff (if applicable) accordingly in respect of the model to claim the ORER rebates. When using gas boosting, the continuous gas unit should be installed as close as possible to the most use out‐ lets and tank as well to reduce the heat loss from the pipe. ...

General Installation PIPING Plumbing connections and pipe arrangement must be in accordance with the installation diagrams as noted in this manual and comply with the AS3500.4 (in Australia) and local water authority and building regulations. All pipe work shall be copper and completed in a neat and economical layout, using long radius bends and less bends to ensure that the resistance to flow rate through the pipe work is minimised. Pipe work shall run straight at a constant grade. To reduce the heat loss from the piping all hot water pipe work should be as short as possible and needs to be insulated by Armstrong, Armaflex or similar in thickness of 13mm. These should include solar flow‐from tank to collector, solar return‐from collector to tank and hot outlet from tank service to the end‐user. Pipe work shall be flushed out to ensure no foreign matter remains in and purged before attempting to oper‐ ate the water heater. To check the leakage from the joints the pipe work shall be pressure tested to 1.5 times the working pressure of the system or 1000kPa, whichever is greater. Approved flush must be kept when pipe penetrating the roof to water proof. All pipe work within the roof space should be securely clipped to prevent vibration. Drainpipes should be clear of any possible obstruction. Under no circumstances should plastic piping be used and will void warranty if fitted. Do not power up the controller until commissioning as it controls the pump. The pump must only be active after the solar circuit has been filled with water/fluid and air has been expelled. The pump chamber will automatically bleed the air our after a short period of operation. For indirect system the Long pipe runs shall incorporate expansion loops or bends to allow for thermal expan‐ sion. These shall be installed horizontally to avoid forming air locks. SOLAR COLLECTOR CONNECTIONS SOLAR FLOW – from tank to collector/s The solar flow line (from tank to collector) should be connected from the bottom of the storage tank where marked “to collector” to the “inlet” of the collector/s on the roof. Via a 20mm brass tee piece the circulation pump fit to the tank. An arrow on the pump indicates the way of water/fluid flow. Orient the pump upward to ensure the pump draws water from the tank and forces it up to the collectors. One way valve (non return valve) ...
Both solar flow and return lines should be used copper pipe insulated by solar rated Armflex with minim 13mm wall thickness. In low water pressure areas (<350kPa), an air bleed valve should be installed via tee at the hot outlet of the collector in the highest point of the system to avoid air blockage. The air release valves shall be left on the open position to ensure all the air can escape from the system. To open the valve: turn the valve clockwise till tight to close then turn anti‐clockwise 360 . Use hand to tune the valve only, do not use tools. TANK CONNECTIONS Cold water supply The storage tank has a pressure/temperature relief valve set at 850 kPa. The cold water inlet pressure should not exceed 650 kPa. A pressure reduction valve must be fitted adjacent to the cold water inlet if this is not the case. In some locations regulations require a pressure relief valve be fitted to the cold water supply. The cold water inlet is 20mm FI and located at the bottom of the tank marked "cold inlet". The cold water inlet requires an approved isolating/non return valve. As shown in the connection diagrams, the drain connection is incorpo‐ rated in the cold water expansion control valve located at the cold water inlet for all the models. The relief valve will discharge a small amount of water when the system is heating and should be checked every six months. Hot water supply The hot water outlet from the tank is located at the top of the tank with 20mmFI where labelled “Hot outlet”. All the hot water pipes need to be insulated to prevent heat loss. As required by the National Plumbing Code, an installer/plumber MUST fit a tempering valve to the heater to prevent the water temperature going to the home exceeding a preset safe maximum. The tempering valve should be connected to the hot water outlet lines. The valve must be fitted at the time of system installation or in retrofitting to existing systems. SOLAR CONTROLLER The solar controller operates on a difference of temperature which is measured by the two temperature sen‐ sors; tank sensor (fitted into bottom of the tank) and collector sensor (fitted into collector). The Solar control‐ ler turns the circulating pump on or off according to the difference of temperature that has been preset. The pump is automatically turned on when the collector/s temperature is approximately 9°C higher than the tank. It then is turned off when the temperature differential is ...
PLEASE DON’T WRAP THE WIRE ATTACHED TO THE COPPER PIPE WITHIN THE INSULATION (ARMFLEX) The solar sensor wire will need to be run with return lines from collectors to tank. Make sure the sensor probe is inserted into the sensor pocket and fixed the position by tighten the sensor flange. Make sure the sensor wire is protected from damage. If this wire is cut or broken it will need to be rejoined soldered and shrink sealed. Ensure the sensor wire does not come into contact with solar circulation copper pipes, as very high temperatures can melt the insulation of the wire causing a short‐circuit and controller malfunction. System Temperatures Solar systems are able to heat the water to very high temperatures. This leads to the following concerns, • temperature of water delivered from taps A tempering valve must be installed to limit the water temperature delivered at the taps. If there is already one installed, its correct operation should be confirmed and the valve replaced if there is any doubt over its operation and correct function. The function of this valve shall be regularly checked and be appropriately maintained. • damage to system components Some components installed in conventional hot water systems are not compatible with the high temperatures experienced in solar hot water systems. Of particular concern are; 1. Mains pressure hot water cylinders which, unless manufactured specifically for use in high tempera‐ ture systems, have a recommended temperature limit. In many cases this will be between 70°C to 80°C. 2. The specification of the installed cylinder should be checked and a temperature limitation device in‐ stalled to limit the temperature within the cylinder to within acceptable limits. The solar controller has this function and should be programmed to suit. Pressure and Temperature Relief Valve Pressure and temperature relief valve (850kPa, 10kw) and Outlet tee must be screwed to P&T valve of the tank. A drain pipe must be fitted to the relief valve to let the excess pressure and temperature escape when the sys‐ tem is heated. The pipe work from the relief valve to the drain should be as short as possible, and fall all the way from the water heater with no restrictions and frost‐free. It should have no more than three right angles bend in it. The outline of the drain pipe must be in such a position that flow out of the pipe can be easily seen but the discharge will not cause injury, damage or nuisance (refer to AS3500.4). ...
. The above is a guide only and subject to local electrical authority and customer requirements THERMOSTAT An adjustable thermostat is fitted and preset at 60 C. This can be adjusted to suit individual requirements. If a higher temp is required both the thermostat and the controller boost profile must be changed accordingly and pre‐approved by Solar Lord. CABLE Connection to the element is via the entry hole of the electrical box at bottom of the cover. Remove the in‐ spection cover and connect active, neutral and earth wires as marked. The connection diagram provided inside of the cover. Electrical cables should be closed in weatherproof conduit and fittings, where required. A sepa‐ rate supply cable from the electrical meter box to the booster element and off peak elements should be in‐ stalled. Only use electrical cable/wiring with a temperature rating of >106°C to inside the appliance box. SWITCHES An on‐off switch for the solar system should be installed in the meter box. An existing unused on‐off switch may be used provided it is of the correct current rating and is in sound condition. GAS CONNECTIONS Gas Booster (for G series only) Solar Lord gas booster is an instantaneous gas heater designed for external use only. The cold inlet of the gas heater should be connected to hot outlet of the solar storage tank Details show at page 15. ...

For information relating to overall dimensions and connection points refer to diagrams. THE SOLAR COLLECTOR INSTALLATION SOLAR COLLECTOR LOCATION To get the full benefits of a solar water heater the collector/s must be installed at a facing north area with proper exposure to the sun without shading. A tilt angle equal to the local latitude will maximize annual solar gains. It is usually acceptable to mount the collector/s flush on a pitched roof close to the optimal orientation as possible in order to reduce installation cost and improve aesthetics. The installation of the solar collector/s must comply with the requirements of AS/NZS 3500 and all local codes and regulatory authority requirements. The roof must be suitable to take the mass of the solar collector/s. Each panel weighs about 67kg when empty and 70 kg when full of water or glycol. SET‐UP THE SOLAR CIRCUIT ...

Solar Lord Enamel (glass) lined mains pressure hot water tank is fitted with a Sacrificial Anode, which protect the tank from corrosion. The Anode is “sacrificial”, meaning that it is a softer alloy than the cylinder and all corrosion will occur at the Anode and not your cylinder. Sacrificial anodes do not last much longer than the standard warranty period of the tank. We recommend that they are checked and replaced every 3‐4 years to ensure the maximum life of your tank. In addition we recommend that your tank should be drained and flushed every 5 years. The following table is a guide to anode replacement intervals. Total Dissolved Solids (ppm) ‐ Recommended anode replacement interval 0 ‐ 1000 ‐ 5 years 1,000 or more – 2‐4 years. We recommend the installation of water filter when using water heaters in areas with high levels of total dis‐ solved solids, to maximise the efficiency of the water heater. Solar Circuit: 1. Open the expansion valve on the top of the collector. Prepare a metal container under the filling valve on the tank. Open the filling valve. Allow the fluid to drain to the container (Closed Loop only). Attention: The glycol fluid can be very hot. Care must be taken to avoid scalding. Discharged fluid should be disposed of in accordance with the relevant local authority (refer to appendix A) 2. Disconnecting solar flow and return pipes remove washers and clean any debris from fittings. Replace new washer on solar flow and return pipes and reconnect to the tank as before. 3. Remove the tile underneath the clips and visually inspect the braces are securely fixed to the rafters. Inspect the rafter for any signs of decay. If inspection reveals no deterioration replace the tile back. For metal roof visually inspect signs of decay and refit the collectors on the roof. Replace or secure the fas‐ tening as required. 4. Inspect the collectors for visible defects. Check any evidence of burning or gassing on collectors. A clear visual of the tube indicates its vacuum status. The silver barium layer at the bottom of the tube will turn white if the vacuum is ever lost. Check any cracking or breakage on surface of the evacuated glass tubes. Broken/damaged tube/s must be replaced (refer to APPENDIX B). 5. Unscrew the interconnections between the panels and clips at four corners of each panel and clean any debris. 6. Replace with new washers and re‐connect. 7.
OWNER’S MANUAL Congratulations on your wise investment for choosing a Solar Lord hot water system. You will be rewarded for many years of monetary savings, and are helping provide a sustainable future for generations to come. Understanding your system and how the system works will help you run your system efficiently. (Please refer to THE PRINCIPAL OF OPERATION on page 6) Solar hot water is a slow heating system. Depending on the season, the system will initially take 2‐ 3 days to build up the water temperature. In the morning, if most of the hot water has been used the hot outlet on top of the tank will be cold. The water will be heated up gradually and get warmer then hot at the end of a clear day in summer. For those existing houses there may be some minor changes Water pressure reduced When a new hot water unit is installed, a Pressure limiting valve (PLV) is installed in accordance with AS/NZS 3 500 National Plumbing and Drainage Code. Hot water temperature Solar hot water can de‐ liver water at temperatures which can cause scalding. To comply with Government health and safety regula‐ tion It is required that a temperature limiting device be fitted between the water heater and the hot water outlets. Operating Your Solar Lord Water Heater The systems performance and its energy savings will depend on your hot water usage pattern and the manner with which you are boosting your electric back up. Solar Lord Systems are equipped with collector/s suiting the capacity of the tank in proportion to the annual solar radiation. Solar energy is the fuel of solar water heaters. Unlike other fossil power the solar energy varies daily and seasonally. The average solar energy in winter is a quarter of the solar energy in summer. Winter so‐ lar energy is much less than in summer. And the cold water temperature in winter is much lower than summer. Evacuated glass technology has greatly improved the collector performance in winter and significantly over‐ come the traditional flat panel’s problems in winter. But systems still consume the small amount energy in winter due to the limited solar energy and larger energy requests. Therefore we recommend you turn your washing machine on cold wash in winter and warm/hot wash in summer. Variations on energy demand and input ...

Hot water usage Your solar system is designed to utilize a combination of solar energy and purchased energy, operating simulta neously, to maintain a minimum operating temperature of 60°C degrees (to kill bugs in system). The stored solar hot water will quickly run out for the house using old shower heads or a bath tub, therefore m ore back up energy will be used. We highly recommend upgrading your shower heads to AAA which have a flo w rate of 6 litres per minute rather than 12‐15 L per minute on older heads. This DOUBLES your solar hot wat er capacity. Back up Instantaneous Gas Booster (Gas models) Nature Gas and LPG Instantaneous Gas Boosters are the most economical way to boost your Solar Hot Water, as they only utilize gas when hot water is drawn down. To prevent Legionella bacteria growth within water‐ heating appliance, Australian Standards requests the instantaneous gas booster to heat water up to 70C. The booster only heats the solar pre‐heat water to 70 C when it flows through and is able to deliver continuous hot water whenever you need. Continuous Power (Electric models) The continuous connection will heat your tank at any time if there is no solar gain. Heating element is installed in middle of the tank to allow solar input during the day. Your Solar Lord water heater is designed to utilize the annual solar energy to heat the water and fossil energy to booster the water temperature as requested. As such, we suggest that you leave your electric booster switch ON to ensure that adequate hot water is always available. Alternatively a time clock can be fitted to turn the booster ON at predetermined times accordance with your usage pattern. This method can further increase energy savings. Off Peak Power (Electric models) If your Solar Lord water heater is connected to an ‘Off Peak’ (night rate) electrical supply, it is important to re‐ member that the booster will only operate late at night and heat top half of the tank. On cloudy days the tank may only gain a small amount of solar energy. Careful planning & usage will be required to avoid running out of hot water if large quantities are used during the day. In areas where a ‘Day Rate’ electrical switch is permit‐ ted, the storage tank can be boosted manually to ensure hot water is available when you need at the end of the day. ...

the solar pipe work when ambient temperature drops below 1 C . This is to prevent the water inside the pipe work from freezing. It is essential that the electrical power supplied to the solar control unit in any circum‐ stance. Damage caused by freezing due to no power at the solar control unit, is not covered by the Solar Lord war‐ ranty. Notes: Solar Lord evacuated glass tube collector made a perfect nature insulation layer between two glass tubes be evacuated to prevent freeze damage. If a tube is broken in winter then there is a risk of freezing in those cold areas. It is necessary to have your plumber drain the solar collectors and solar flow and return pipe work immediate until a new tube to be replaced. The system is not covered by warranty for a broken tube system. WARNING: NO ATTEMPT SHOULD BE MADE TO REMOVE COLLECTOR GLASS TUBE/S SOLAR CONTROLLER MUST BE CONNECTED TO POWER IN ANY CIRCUMDANCE OVER‐HEAT PROTECTION Solar Lord Controller has built with over heat protection and holiday program which should be used when you away from home. The overheat protection system will be rendered inoperable if electrical power is not avail‐ able at the solar control unit. Damage caused by over heat due to power fail to the solar control unit, is not covered by the Solar Lord warranty. NOISE FROM THE SOLAR COLLECTORS When the solar storage tank temperature reaches 65 C, the circulator pump will be turned off. The water in the solar collectors will continue to gain heat and increase in pressure during the rest of the day (when solar radiation is still available). When a hot tap is opened, this pressure is released and the high temperature water may turn to steam creating pressure fluctuation and result in a sudden and loud rumbling noise and even a rattling or banging noise of the collectors against the roof cladding material. This results from the higher level of solar radiation and the water in the solar storage tank being at its maximum temperature and is not caused by a fault with the solar water heater. The quick and easy ways to solve the problem are 1) turn off the power to the auxiliary heating (i.e. switch off the hot water element from the switch box for electric back up models or turn off the power point to the gas booster from power socket on the wall). 2) Draw more hot water during a summer clear day whenever you do wash thus to release the pressure ...

SHADE FREE Solar radiation is greater on sunny, clear days between 9am and 3pm. Ensure that the surroundings do not cast shadows on to the collector during this time is essential in winter. It is recommended that you prune or cut tree/s or branches annually if trees are around the area. Partial shading by Buildings/Structures object, like chimneys, TV antennas, and roof erected fixtures, etc. dur‐ ing these hours is acceptable provided that it does not exceed 10% of the solar collectors. Shading created by new buildings should be checked. If system performance is affected, relocation of the system may be neces‐ sary. Consult your nearest Solar Lord dealer if relocation is required. COLLECTOR CLEAN Generally adequate rainfall should wash the dust away from the panels. However care must be considered for extremely dusty areas or areas subject to dusty/sand storms, the glass tubes of the collector should be washed with clean water at least every three to six (3‐6) months. DO NOT USE HIGH PRESSURE GUN WHICH MAY CAUSE GLASS TUBE CRACKING AND WILL VOID THE WARRANTY! ON AN OVERCLOUDY‐DAY Insufficient sunlight on a cloudy or rainy day will make the system provide less or lukewarm water. Avoid heavy usage of hot water and spread hot water usage evenly throughout the day. In the continuous electrical booster models the thermostatically controlled supplementary booster will ensure the water temperature is heated to 60°C before the water is used. While off‐peak models only booster at the midnight, if you use all the hot water in the morning, you may get lukewarm water during the day or evening in heavily overcast days. WHEN HIGH SOLAR RADIATION In a clear day, solar preheated hot water systems can produce hot water at temperatures far higher than the thermostat setting so very little or no electrical energy will be used. ELECTRIC BOOSTER TIMER SETTING (E SERIES ONLY) Tips During winter periods the human body generally prefers hot water above 40ºC to show, so boosting is essential for comfort. Boosting late afternoon/early evening for the maximum use of solar energy during the day is taken ad‐ vantage. Boosting overnight or early in the morning if your hot water heavy usage is requested in the morning. The high temperature boost times should be structured prior to heavy usage period, because the ele‐...

over 45ºC can scald and care needs to be taken to ensure that injuries do not occur through incorrect use of your water heater. As required by the National Plumbing Code, a tempering valve MUST be fitted to the heater to prevent the water temperature going to the home exceeding a preset safe maximum. The tempering valve is connected to the hot water outlet lines. The valve must be fitted at the time of system installation or in retrofitting to exist‐ . ing systems WARNING – HOT WATER BURNS. AS A SAFETY PRECAUTION, YOUNG CHILDREN SHOULD NEVER BE ALLOWED TO OPERATE WATER HEATERS OF ANY TYPE. When return from Holidays If the water heater is left unused for two weeks or more a small quantity of hydrogen gas, which is highly flammable, may accumulate in the top of the water cylinder. To dissipate this gas safely it is recommended that a sink or bath hot tap be turned on to dispel a couple of litres of water. During this procedure there should be no smoking, open flames or any electrical appliances such as washing machines, dishwashers etc, operating nearby. If hydrogen is discharged through the tap it will make a sound like air escaping. REGULAR CARE Operating the temperature and pressure relief valve The temperature and pressure relief valve is located on the top of the storage tank and is essential for system operation. The temperature and pressure relief valve is required to be flushed every six months. To release the pressure/temperature relief valve on the tank, simply hold the relief arm level open. The valve easing lever should be operated for several short periods to verify operation. Keep temperature and pressure relief valve and COLD EXPANSION VALVE drain pipe block free The temperature and pressure relief valve and cold expansion valve drain pipe must be clean and not be blocked in any way. DANGER ‐ FAILURE TO OPERATE THE RELIEF VALVE EASING GEAR AT LEAST ONCE EVERY 6 MONTHS MAY RESULT IN THE WATER HEATER EXPLODING. CONTINUOUS LEAKAGE OF WATER FROM THE VALVE MAY INDICATE A PROBLEM WITH THE WATER HEATER. Keep the collectors clean Dust on the surface of the glass tube will shelter the absorber inside of the tube from sunlight. Inspect for the sign of dust accumulate on the tubes every three to six (3‐6) months. The collector should be washed with ...
It is recommended that a Solar Lord Service Technician carry out a regular service every five (5) years. Call So‐ lar Lord Service to arrange the service every seven years after the system is installed. Additional service is also available for solar hot water systems installed in areas of high Calcium or hard water. Caution Under normal household use, the system will operate between 55ºC and 65ºC. However, during periods of high solar radiation, particularly in summer, temperatures may exceed this. As a safety precaution CHILDREN should not operate hot water outlets. Pay particular care and attention when returning from holidays or vaca‐ tion. COLD EXPANSION VALVE In certain states of Australia this valve is a mandatory requirement by the local Water Authorities. The cold water expansion valve is set to operate at 700kPa due to thermal expansion of water while the system is heat‐ ing up either by the sun or electrically. The water discharging from the valve is normal and ensures correct functioning. The discharge will be in the form of drips and it is possible to lose between 3 ‐ 5% of the total storage capacity of the tank per day. Despite the detail set out in this manual, it must be remembered that: Product designs, functions and specifications are constantly changing and although every effort has been made to ensure the information contained in this manual is correct and current at the time of printing it is always possible that the information will have changed in the meantime. This is necessarily a concise manual and it cannot cover every conceivable situation that might arise. No matter how much one can learn from reading information there is no substitute for the training and experience of a qualified tradesperson or hydraulic designer. For these reasons Solar Lord cannot accept any liability with respect to any alleged loss or damage that might arise if the information has become outdated or if the circumstances are such that it would have been prudent for the person concerned to have employed the services of someone expert and experienced in the field. Water Quality Water that contains a high percentage of foreign matter, is of poor or unacceptable quality or contains low chlorine concentrations can lead to blockages, corrosion or premature failure of the systems. Such failures are out of acceptable limits and are not covered by the warranty. Systems operating under such conditions should have their periodic maintenance increased to suit. APPENDIX A ...
