Unvented hot water storage vessels need regular routine checks, and these are detailed below. It is for this reason that this manual must always be left with the Stainless Lite Horizontal. All cylinders are manufactured in accordance with the requirements of BS EN 12897 The tundish must be positioned so that it is visible to the occupant and is away from electrical devices. Components supplied with Stainless Lite Horizontal: • Cold water inlet PRV combination valve/expansion relief • Pressure and temperature relief valve • Control thermostat / Energy cut-out thermostat • Energy cut-out motorised valve (indirects only) • Tundish • 3kW Immersion heater including control and cut out thermostats • Expansion vessel/mounting bracket/flexible hose • Technical/user product literature (Note: Please refer to tables 1 and 2 on pages 6-7 to confirm the quantity of immersion heaters supplied with the unit) In any situation where the volume of heated pipework (eg. secondary circulation pipes or manifold pipework for multiple units) exceeds 10 litres, then an additional expansion vessel must be fitted to accommodate the extra expansion volume. Handling Before Installation Stainless Lite Horizontal must be handled with care and stored in a dry place. Any manual handling/lifting operations will need to comply with the requirements of the Manual Handling Operations Regulations issued by the H.S.E. The appliance can be moved using a sack truck on the rear face although care should be taken and the route should be even. In apartment buildings containing a number of storeys we would recommend that the appliances are moved vertically in a mechanical lift. If it is proposed to use a crane, expert advice should be obtained regarding the need for slings, lifting beams etc. A specific manual handling assessment is shown in Appendix B at the rear of this manual. It is essential that these checks be carried out at the time of boiler maintenance by a qualified installer: 1.Manually open the relief valves in turn, and check that water is discharged from the valves and runs freely through the tundish and out at the discharge point. Ensure that the valves re-seat satisfactorily. (Note - the water may be very hot). 2.It is important to check that the discharge pipework is carrying the water away adequately. Check for blockages etc. if it is not. 3.Turn the mains water off and remove and clean the strainer element in the Pressure Reducing Valve. 4. Check the charge pressure in the expansion vessel and repressurise if required 5.Re-fill the system and ensure that all relief valves have re-seated. 6.The Benchmark Service Record should be updated at each service. 7.Check the water pressure downstream of the combination valve is 3 bar in static condition. 8.Check and if necessary, descale the heat exchanger in hard water areas ie. above 200ppm (mg/l). Note: The cylinder is factory fitted with a temperature & pressure relief valve that must not be used for any other purpose or removed. The cylinder is factory fitted with immersion heaters with thermal cut outs. Immersions without thermal cut outs must not be fitted. Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code of Practice which is available from the Heating and Hot Water Industry Council who manage and promote the Scheme.

Page 7 SYSTEM DESIGN INSTALLATION INSTALLATION General Design Considerations Insulation of pipework The unit must be installed on the supports provided. The supports must be aligned with the embossed marking. This ensures that the pressure and temperature relief valve is vertical in the cylinder. The base chosen for the cylinder should be level and capable of supporting the weight of the unit when full of water as shown in General Data. The discharge pipework for the safety valves must have a minimum fall of 1 : 200 from the unit to a safe discharge point. All exposed pipework and fittings on the cylinder should be insulated, and the unit should NOT be fixed in a location where the contents could freeze. In new systems, pipes should be insulated to comply with building regs, the maximum permissible heat loss is indicated in the table opposite, and labelled accordingly as follows: i. Primary circulation pipes for domestic hot water circuits should be insulated through their length, subject only to practical constraints imposed by the need to penetrate joists and other structural elements. ii. All pipes connected to hot water storage vessels, including the discharge vent pipe, should be insulated for at least 1 metre from their points of connection to the cylinder (or they should be insulated up to the point where they become concealed). In replacement systems, whenever a boiler or hot water storage vessel is replaced in an existing system, any pipes that are exposed as part of the work or are otherwise accessible should be insulated as recommended for new systems, or to some lesser standard where practical constraints dictate. Standard Model Selection Guide Max hot water demand Max number of bed spaces (Bedrooms) Indirect litres 1 bathroom + 2 separate shower rooms or 2 bathrooms 7 (5) 180 2 bathrooms + separate shower room 7 (5) 210 2 bathrooms + 2 separate shower rooms 7 (5) 250 3 bathrooms 9 (6) 300 Solar Model Selection Guide Max hot water demand Indirect litres Bedrooms 1 bathroom 1-3 180 1 bathroom + 1 shower room 1-3 210 1 bathroom + 2 shower rooms 2-4 250 2 bathrooms + 1 shower room 3-4 300 Protrusion from cylinder Pipe outside diameter Maximum heat loss 15mm 7.89W/m 22mm 9.12W/m 28mm 10.07W/m 35mm 11.08W/m The pipe connecting the boiler flow to the appliance must not be less than 22mm copper or equivalent. Further guidance on converting heat loss limits to insulation thickness for specific thermal conductivities is available in TIMSA “HVAC guidance for achieving compliance with Part L of the Building Regulations”. Mains Water Supply Existing properties with a 15mm supply will be satisfactory provided the local mains pressure is good, but should be confined to single bathroom properties. For new properties where simultaneous demand is required to more than one bathroom or a bathroom and one or more en-suites, the communication and service pipe into the dwelling should be a minimum of 22mm (usually in the form of a 25mm MDPE supply). The optimum performance is achieved if the inlet pressure is 3 bar dynamic. However, the Stainless Lite Horizontal will function with lower inlet pressures, but this will reduce the performance. For optimum performance, 30L per minute incoming mains flow should be present, however the Stainless Lite Horizontal will work at lower flow rates, although performance will be affected. Normally Stainless Lite Horizontal provides well in excess of 40 litres/min in most conditions. Flow rates for ALL mains pressure systems are subject to district pressures and system dynamic loss. Particularly on larger properties with more than one bathroom, the pipe sizes should be calculated in accordance with BS EN 806-3:2006 and BS 8558:2011.

The highest hot or cold water draw off point should not exceed 10 metres above the Pressure Reducing Valve. b. An ascending spray type bidet or any other appliance with a Class 1 back-syphonage risk requiring a type A air gap should not be used. c. Stainless Lite Horizontal should not be used where steam is the primary heating medium, or in a situation where maintenance is likely to be neglected. d. Unvented cylinders are not suitable for use with solid fuel boilers. e. If the supply to the mixer fittings (other than a dual outlet type) is not taken from the balanced supply the system will become over pressurized and cause the pressure relief valve to discharge. Over time this could also cause the premature failure of the appliance itself which will not be covered by the warranty. f. In larger properties with a number of bathrooms/en-suites and long pipe runs we would recommend that the balanced cold supply is provided with its own pressure reducing valve and is not taken from the balanced cold connection on the combination valve. In this case it will also be necessary to fit a small expansion vessel on the balanced cold water system to accommodate the pressure rise caused by the increase in temperature of the balanced cold water. g. 0Check the performance requirements of the terminal fittings with regard to flow/ pressure are suitable. h. In relation to potable water systems, expansion vessels shall be installed in a vertical orientation and located so that the length of the connecting pipe work is kept to a minimum. In all mains pressure installations it is important to remember that the incoming cold supply must be shared between all terminal fittings. It is important that a 22mm supply is brought to the appliance and a 22mm take-off is continued at least to the bath. If there are two baths, 28mm pipework should be considered. One metre of smaller diameter pipework, or flow restrictors, should be provided on the final connection to all outlets so as to balance the water available. In any event the distribution pipework should generally be in accordance with BS EN806-1 to 5. Shower Fittings Aerated taps are recommended to prevent splashing. Any type of shower mixing valve can be used as long as both the hot and cold supplies are mains fed. However, all mains pressure systems are subject to dynamic changes particularly when other hot and cold taps/showers are opened and closed, which will cause changes in the water temperature at mixed water outlets such as showers. For this reason and because these are now no more expensive than a manual shower we strongly recommend the use of thermostatic showers with this appliance. These must be used in 3 storey properties where the impact on pressure/temperature of opening another tap in the system is greater than normal. The shower head provided must also be suitable for mains pressure supplies. SH DHW WC ERV/NRV PRV SCV Plastic Pipework This appliance is suitable for use with plastic pipework as long as the material is recommended for the purpose by the manufacturer and is installed fully in accordance with their recommendations. Secondary Hot Water Circulation Some models are fitted with a secondary return tapping as standard (see tables 1 and 2 for details). If fitted, an extra expansion vessel may be necessary. A non-return valve MUST be FITTED near the return connection. No valve or terminal fitting should be installed between the non return valve and the cylinder. (See schematic arrangement on page 15.) All pipes kept hot by the secondary circulation should be insulated. WHB P&T SCV BATH Note: Cold supplies to single taps must be taken from the mains cold water system.

P&T Relief Valve Dotted line showing alternative route with single tundish being used 300 mm min. Discharge below fixed grating 22 mm metal pipe with continuous fall up to 9m equivalent length (D2). NOTES: Fixed Grating The discharge will consist of scalding waterand steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges. It is not acceptable to discharge straight into a soil pipe. Trapped gully Worked Example The example below is for G1/2 temperature relief valve with a discharge pipe (D2) having 4 elbows and length of 7m from the tundish to the point of discharge. From the table below: Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from a G1/2 temperature relief valve is: 9m subtract the resistance for 4 x 22mm elbows at 0.8m each = 3.2m. Therefore the maximum permitted length equates to: 5.8m. 5.8m is less than the actual length of 7m therefore calculate the next largest size. Maximum resistance allowed for a straight length of 28mm pipe (D2) from a G1/2 temperature relief valve equates to: 14m. As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory. Sizing of copper discharge pipe ‘D2’ for a temperature relief valve with a G1/2 outlet size (as supplied) Size of discharge pipework Maximum length of straight pipe (no bends or elbows) Deduct the figure below from the maximum length for each bend or elbow in the discharge pipe 22mm Up to 9m 0.8m 28mm Up to 18m 1m 35mm Up to 27m 1.4m The following information is taken from Approved Document G3 of the Building Regulations and is provided to assist with the design and installation of the discharge pipework. However, the information is not exhaustive and reference should always be made to Approved Document G3 of the Building Regulations. The final decision regarding any arrangements rests with Building Control and it is recommended that their advice is sought if you have any concerns regarding this aspect of the installation. The two safety valves will only discharge water under fault conditions. When operating normally water will not be discharged. The tundish should be vertical, located in the same space as the unvented hot water storage system and be fitted as close as possible and within 600mm of the safety device e.g. the temperature relief valve. The discharge pipe (D2) from the tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge, be of metal and: a) Be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9m long i.e. discharge pipes between 9m and 18m equivalent resistance length should be at least two sizes larger than the nominal outlet size of the safety device, between 18 and 27m at least 3 sizes larger, and so on. Bends must be taken into account in calculating the flow resistance. Refer to the table and the worked example. An alternative approach for sizing discharge pipes would be to follow BS EN 806-2:2005 Specification for design installation, testing and maintenance of services supplying water for domestic use within buildings and their curtilages. b)Have a vertical section of pipe at least 300mm long, below the tundish before any elbows or bends in the pipe work. d) It is preferable for the discharge to be visible at both the tundish and the final point of discharge but where this is not possible or practically difficult there should be clear visibility at one or other of these locations. Examples of acceptable discharge arrangements are: 1. Ideally below the fixed grating and above the water seal in a trapped gulley. 2. Downward discharges at a low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc are acceptable providing that where children play or otherwise come into contact with discharges, a wire cage or similar guard is positioned to prevent contact whilst maintaining visibility. 3. Discharges at a high level; e.g. into metal hopper and metal down pipe with the end of the discharge pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering systems that would collect such discharges. 4. Where a single pipe serves a number of discharges, such as in blocks of flats, the number served should be limited to not more than 6 systems so that any installation can be traced reasonably easily. The single common discharge pipe should be at least one pipe size larger than the largest individual discharge pipe to be connected. If unvented hot water storage systems are installed where discharges form safety devices may not be apparent i.e. in dwellings occupied by blind, infirm or disabled people, consideration should be given to the installation of an electronically operated device to warn when discharge takes place. Safety The safety devices supplied or fitted on an Stainless Lite Horizontal are selected for their suitability for the temperatures and pressures involved. They must not be changed, removed or by-passed and it is essential that only genuine replacement parts supplied or approved by Gledhill Building Products Limited are used. This includes the immersion heaters, which must incorporate an energy cut-out. All parts are available to approved installers from Gledhill Building Products Limited, Sycamore Estate, Squires Gate, Blackpool (Telephone 01253 474402). Please Note The pressure and temperature relief valve for the vertical Stainless Lite models is not compatible with the horizontal Stainless Lite. Combination Inlet Group Combines elements 1, 2 and 3 below. 1. Pressure Reducing Valve - This must be fixed near the cylinder. The cold water supply to any mixer taps/showers must be taken from the cold water tapping of this valve to ensure balanced hot and cold pressures. This valve is factory set to ensure the correct operating pressure for the Stainless Lite Horizontal. 2. Non Return Valve - This is integral with the pressure reducing valve to prevent backflow of hot water towards cold water draw off points. 3. Cold Water Expansion Relief Valve - This safety device is preset at the factory and will relieve excess cold water pressure resulting from a fault condition.

Please refer to tables 1 and 2 to clarify how many off peak and on peak immersions are included with the unit you require. Schematic Sealed Primary System External wiring to the immersion heaters must be in accordance with the relevant IEE Wiring Regulations and the circuit must be protected by a suitable fuse and a double pole isolating switch. Motorised Valve (Energy cut-out) The correct method of terminating the wiring to the immersion heater is shown above. Gate Valve (Not supplied) Usage of the product in non-domestic commercial applications can be extremely intensive and stressful to various components. Line Strainer This is integral within the combination inlet group to reduce the likelihood of contaminants fouling the valve seat. Following installation this line strainer must be cleaned and replaced. This needs to be carried out on a regular basis. as part of the annual maintenance/service check. Expansion Vessel Safety Valve Gauge Motorised Valve (Not supplied) Tundish This is to allow the discharge from any Relief Valve to be seen. It must be fitted away from any electrical devices. See page 14 for discharge pipework details. Pump Boiler Primary Circuit Sealed Primary Circuit Any boiler used must be fitted with an over temperature cut-out. Unvented primary circuits may be filled or replenished by means of a temporary connection between the circuit and a supply pipe provided a ‘Listed’ double check valve or some other no less effective backflow prevention device is permanently connected at the inlet to the circuit and the temporary connection is removed after use. Alternatively, a CA device can be used, which will allow the system to be permanently connected to the cold mains supply. The primary system can then be topped up, when required, in the same way as an open vented system fitted with an F&E Cistern. All our cylinders are tested to BS EN 12897 at 15 l/mim at which they exceed the minimum requirements for heat up performance and reheat in less time than the maximum reheat times. The immersion heaters must be earthed and they must be isolated from the mains before the cover is removed on every occasion. Replacement immersion heaters should be obtained from Gledhill Building Products Limited. Solar Thermistors / sensors In extreme situations where excessive flow rates, above 25 l/min are present, then a gate valve on the return from the cylinder to the boiler, before it joins the central heating return, may be required to reduce excessive flow rates and therefore any potential noise problems. Care must be taken to ensure that the solar probes are fully inserted into the pockets provided. Page 12 Safety Gate Valve Safety INSTALLATION The boiler and primary/heating systems should be sized and installed in accordance with BS EN 12828:2003, BS EN 12831:2003 & BS EN 14336:2004. It is essential that the circuit between the boiler and the Stainless Lite Horizontal is pumped. The motorised zone valve supplied should be fitted adjacent to the unit and controlled by the cylinder thermostat supplied. The thermostat and motorised valve must be wired so that they both switch off should an overheat situation develop. It is important to follow the wiring diagram in the Wiring Section of these instructions. Pump Immersion element spade connectors Heating/primary Systems Stainless Lite Horizontal is fitted with a Combined Temperature/Pressure Relief Valve to cope with any increase in system temperature and pressure above the design limitations, when used with boilers up to 45kW output, which is the maximum allowed by section G3 of the Building Regulations. The primary water temperatures should be controlled as outlined below. Minimum distance as required by boiler manufacturers instructions In line with good plumbing practice, use of excessive flux should be avoided. Neutral connection point (Blue) Live connection point (Brown) drain the cylinder of hot water and then close all cylinder inlets and outlets. REASON as the air remaining in the cylinder cools the pressure inside the cylinder will fall below atmospheric and cause damage to the cylinder. NEVER close the cold main and drain the cylinder via any tap connected to it. REASON as the water drains, the pressure inside the cylinder may decrease below atmospheric and this may cause damage to the cylinder. Schematic Open Vented Primary System Page 13 INSTALLATION INSTALLATION INSTALLATION Schematic Solar Direct System Solar Panel Solar Controller Expansion Vessel All components in a solar primary system must be marked or identifiable in such a way that their design pressure and temperature can be readily determined. A pressure and temperature relief valve to control the risk of over-pressure in system components should be fitted. A termination from a pressure and temperature relief valve should minimise the risk of damage to persons or materials. Suitable locations are into a high temperature receptacle, an internal gully or externally at ground level. High level termination from walls or on roofs could cause injury to people or animals below if the valve were to release scalding water and steam. Solar Pumping Station The pipe leading to the safety device and the collector should be of rigid and non-deformable construction, without any possibility of restriction or disclosure by any other fitted component. Motorised Valve Energy cut-out (Not supplied) A more detailed diagram of our recommended arrangement for a typical solar system is shown on page 20. Schematic Solar Indirect System Solar Panel Motorised Valve Energy cut-out (Not supplied) Solar Controller Expansion Vessel Solar Pumping Station Motorised Valve Energy cut-out (Not supplied) This provides all the necessary controls and safety devices necessary for the solar system i.e. the two port zone valve is wired as an energy cut out and the pump/valve will only allow heat transfer as required under control of the solar controller. The solar pocket provided accommodates an 8mm diameter sensor which, with the sensor located in the solar collector (or in the flow pipe immediately adjacent to the collector), will provide the information required by the solar controller. Note: If the motorised valve is not used then any factory built hydraulic station for solar use MUST be fitted with suitable non-return valves in both flow and return pipes to prevent gravity circulation when the pump is not running. If there is a possibility of the solar controller that you install causing the cylinder temperature to exceed 80°C, under normal working conditions, then a Solar tempering valve must be fitted to the domestic hot water outlet of the cylinder. This must limit the hot water temperature to a maximum of 60°C.(ref building regulations part G3 3.63). This product can be supplied from Gledhill part number XC007 which has a inlet temperature limit of 100°C. Suitable plumbing configurations for installing this valve are shown on page 19 of this manual. NB. Any fitted Overheat thermostats may require resetting in the winter months to enable backup heat sources to heat the cylinder.

If this is the case, then the warranty should be null & void. The key requirements to comply with these regulations are: 1. Any fitting or material in contact with potable water (e.g. a blending valve) must be approved by WRC or an equivalent body. 2. Connections or wiring arrangements must not bypass any safety devices. 3. Any expansion due to heating must not be allowed to expand back into the cold mains. 4. The settings of any safety devices must not be tampered with or adjusted. Figure 1 shows the cold water port of the blending valve connected to the mains cold water supply before the inlet control group. This arrangement is completely unacceptable and illegal because: • the water is allowed to expand in to mains cold water supply. • the vessel will be charged to the incoming mains supply which may be considerably higher than the working pressure of the vessel. If this arrangement is used then the Gledhill warrant will not be valid. Figures 2 & 3 opposite shows how the blending valve can be piped onsite. Figure 3: Cold port of the blending valve connected to mains supply to the vessel after the inlet control group Mixed HW out Mains CW in Page 15 Figure 2 shows the cold water port of the blending valve connected to the balanced cold water outlet. This arrangement will only be acceptable if a WRAS approved non-return valve is fitted, otherwise: • during the heating cycle, the water will expand back into the mains supply, as the regulating valve must not be relied upon to act as a check valve under all operating conditions. • depending upon the characteristics of the blending valve, hot water may also flow from the balanced cold water taps. Figure 3 shows the cold port of the blending valve connected to the cold water supply to the vessel after the inlet control group. This should be the preferred method. It is recommended that the installer should ensure that there is no gravity circulation in the pipework connected to the cold port. If necessary, this can be achieved by fitting a non-return valve or using a thermal trap.

The control thermostat of the immersion heaters for direct heating of our cylinders are set at 60°C. The control thermostat for indirect heat exchanger heat up of our cylinders are usually set at between 60°C - 65°C. During commissioning the actual temperature that the cylinder reaches when the thermostat(s) operate should be tested and adjusted so that it achieves a minimum of 60°C. This temperature needs to be achieved on a regular basis. Check the pressure on the air side of the expansion vessel = 3 bar. This must be done when the water in the cylinder is free to expand in atmospheric pressure or the cylinder and relevant pipe work is empty. Check that the drain cock is closed, and open all the cold and hot water taps and other terminal fittings. Allow the system to fill with water, and to run until there is no air left in the system. Close the taps and inspect the system closely for leaks. Manually open the Relief Valves one by one and check that water is discharged and run freely through the tundish and out at the discharge point. The pipework should accept full bore discharge without overflowing at the tundish, and the valve should seat satisfactorily. In line with good plumbing practice, use with excessive flux should be avoided. When soldering above the cylinder, ensure flux/solder does not contaminate the cylinder below, since this can cause corrosion. Flushing should be done performed as per BS EN 806:4 2010 section 6.2. Allow the cylinder to heat to normal working temperature, then thoroughly flush the domestic hot and cold water pipework through each tap. NOTE: If this appliance is to be installed in other than a single domestic dwelling ie. in an apartment block or student flats etc., the hot and cold water system will need to be disinfected in accordance with BS EB 806:4 2010 section 6.3 and the Water Regulations. Because the Stainless Lite Horizontal appliance is stainless steel, the use of chlorine as the disinfection agent can cause damage unless the appliance is adequately flushed and refilled with the mains water immediately on completion of the disinfection procedure. Damage caused through a failure to do this adequately will not be covered by the warranty. For the reasons mentioned, we recommend the use of a non chlorine based disinfectant such as Fernox LP Sterox as manufactured by Cookson Electronics when carrying out disinfection of systems incorporating these appliances. Your Stainless Lite Horizontal unvented cylinder is automatic in normal use, but requires routine maintenance which is normally carried out at least annually along with the boiler service. The maintenance must be carried out by a suitably competent tradesperson who is qualified to work on unvented cylinders. The checks/work needed are listed in the maintenance part of these Instructions. Remove the filter from the combination inlet group clean and replace. Refill the system and open all hot taps until there is no air in the pipe work. ENSURE CYLINDER IS DRAINED PRIOR TO CHECKING OR REMOVING FILTER FROM THE COMBINATION INLET GROUP. The control thermostat of the immersion heaters for direct heating of our cylinders are set at 60°C. The control thermostat for indirect heat exchanger heat up of our cylinders are usually set at between 60°C - 65°C. During commissioning the actual temperature that the cylinder reaches when the thermostat(s) operate should be tested and adjusted so that it achieves a minimum of 60°C, in order to comply with the Legionella pasteurisation requirements. Allow the cylinder to heat to normal working temperature with whatever heat source is to be used, and check again for leaks. The pressure relief valve or the P&T valve should not operate during the heating cycle. If the P&T valve operates before the pressure relief valve due to high pressure, check that the inlet control group is fitted correctly. When initially opening the taps, a small surge in flow may be experienced, which disappears as the pressure in the system stabilises. This is quite normal with these types of systems and does not indicate a fault. The boiler/heating systems should be filled and commissioned in accordance with good practice following the guidance in BS 7593:2006/the boiler manufacturers instructions. This includes adequately flushing the system to remove any debris that may have been introduced during installation/maintenance. NOTE At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document. In some areas the water will initially appear cloudy, but will quickly clear when left to stand. This is nothing to be concerned about and is due to aeration of the water. WARNING - If water is seen flowing through the tundish, this indicates a fault condition which needs action. If the discharge is hot and continuous, turn the boiler and/or the immersion heaters off, but do not turn off the cold water to the appliance until the discharge is cold. Note: The discharge may stop by itself as the discharge cools. If the discharge is cold and intermittent, no immediate action is needed but this indicates a problem with the expansion vessel. However, in both cases you must call the registered installer / a suitably qualified, competent tradesperson, advise them that you have an unvented cylinder and request a maintenance visit. DO NOT, at any time, tamper in any way with the safety valves or overheat thermostats/ wiring. This must be completed during commissioning and left with the product to meet the Warranty conditions offered by Gledhill. IMPORTANT - DRAIN DOWN PROCEDURE 1 Switch off both the boiler and the immersion heater 2 Open the nearest hot tap and run all hot water until cold, then close it 3 Close the incoming cold main at the stop tap 4 Hold open the pressure and temperature relief valve until water stops discharging into the tundish and leave it open 5 Open the cold taps starting from the highest point and working down to the lowest tap, leaving them open 6 When the cold taps have stopped draining, open the hot taps starting from the highest and working down to the lowest tap 7 Open the drain cock and ensure the pressure and temperature relief valve is held open until the cylinder is empty COMMISSIONING Page 18 Page 19 USER INSTRUCTIONS SERVICING AND MAINTENANCE The Registered Installer is responsible for the safe installation and operation of the system. The installer must also make his customer aware that periodic maintenance of the equipment is essential for safety. Maintenance periods will vary for many reasons. Gledhill Building Products Ltd recommend a maximum of 12 months to coincide with boiler maintenance. Experience of local water conditions may indicate that more frequent maintenance is desirable, eg, when water is particularly hard, scale-forming or where the water supply contains a high proportion of solids, eg, sand. Maintenance must include the following: 1. Check and clean filter 2. Manually check the operation of the temperature relief valve. 3. Manually check the operation of the expansion relief valve. 4. Check discharge pipes from temperature and expansion relief valves are free from obstruction and blockage and are not passing any water. 5. Check the condition and if necessary descale the heat exchangers in hard water areas. 6. Check that water pressure downstream of pressure reducing valve is within the manufacturers limits. 7. Check operation of motorised valve. 8. Check the pressure on the air side of the expansion vessel. This must be done when the volume in the cylinders is cold. 9. Check and advise the householder not to place any clothing or other combustible materials against or on top of this appliance. 10.On completion of the work, fill in the Benchmark Service Record towards the back of this manual. IMPORTANT NOTE When draining down the appliance for any reason, the instructions provided in the Commissioning Section (Page 18) MUST be followed to prevent potential damage to the cylinder. After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on the inside back pages of this document. SERVICING AND MAINTENANCE Scale In hard water areas it is recommended that an in-line scale inhibitor is fitted. Reducing the temperature of the stored water will reduce the rate at which scale forms. If the recovery rate is badly affected, this is an indication that scaling may have occurred. In this event, follow the procedures as recommended by a reputable Water Treatment Company. General No water at the tap. Check that the mains water supply is turned ON. Check the line strainer is not blocked. Check that the combination valve has been fitted so that water is flowing in the correct direction. If the water at the tap is cold, ensure that the boiler has been switched ON and is working correctly. Check that there are no air locks in the primary system. ISOLATE THE UNIT AT THE MAINS ELECTRIC SUPPLY AND THEN CHECK THE FOLLOWING: i. The cylinder thermostat ii. The thermal cut-out, which can be re-set by pushing the red button iii. The motorised valve iv. The boiler thermostat v. The boiler thermostat cut-out (if fitted) ANY ENERGY CUT-OUT MUST NEVER BE BY-PASSED UNDER ANY CIRCUMSTANCES. If the units are not getting hot and the heat source is electrical, ensure that the immersion heaters are isolated from the mains before re-setting the energy cut-out. If the immersion heater(s) need replacing this should be done with the units supplied from Gledhill Building Products Limited. Same day despatch to approved installers can be arranged by telephoning 01253 474402. Discharge From Relief Valves If cold water is discharging from the expansion relief valve into the tundish check the pressure on the expansion vessel when cold and recharge if necessary. If the fault continues and the problem cannot be stopped by operating the easing control a few times then either the Pressure Reducing Valve or the Relief Valve may be at fault. If the cold water pressure is too high, this would suggest that the Pressure Reducing Valve is at fault and the Gledhill approved replacement should be fitted. If the pressure is correct then the Relief Valve will require replacing with a Gledhill approved component. See Commissioning for drain down procedure. If there is an overheat fault and very hot water is being discharged, turn off the heat source, but not the water supply. When the supply is cool, check thermostats and energy cut-outs in the boiler and immersion heaters and replace the faulty component with a unit supplied by Gledhill and check that it works correctly before returning the system to full operation.

Scope This assessment will cover the largest unit within each product range. For specific weights and dimensions please refer to technical data section. Main Hazards Vision may not be clear due to the size of the products. Adopting an incorrect method of lifting may cause injury, attempting to lift these products will require help from others. (Team lifts) Control Measures Manual lifting procedure The lift, key factors in safe lifting are: Individual capability a. b. c. d. e. Balance Position of back Positioning of the arms and body The hold Taking the lead for team lifts a. Balance - Since balance depends essentially upon the position of the feet, they should be apart about hip breadth with one foot advanced giving full balance sideways and forward without tension. In taking up this position, lifting is done by bending at the knees instead of the hips and the muscles that are brought into use are those of the thigh and not the back. b. c. d. e. Taking the lead for team lifts- As more than one person is required for these products ensure that one person is taking the lead. This may be you so ensure that each person that is helping is made aware of the weight and of the items listed within this assessment. Make sure you and any others helping know the route you intend to take that it is clear of any obstructions. Never jerk the load as this will add a little extra force and can cause severe strain to the arms, back and shoulders. If there are steps involved decide on where you will stop and take a rest period. Move smoothly and in unison taking care to look and listen to others helping with the lift. Where possible use a sack truck to move the product over long flat distances, only lift the products when necessary. If in doubt stop and get more help. Position of back - Straight - not necessary vertical. The spine must be kept rigid, this coupled with a bent knee position, allows the centre line of gravity of the body to be over the weight so reducing strain. Positioning of arms and body - The further arms are away from the side, the greater the strain on the shoulders, chest and back. Keep elbows close to the body arms should be straight. The hold - Before lifting ensure you have a good hold. Individual capability plays an important part in handling these products. Persons above average build and strength will find it easier and should be in good health. Persons below average build and strength may require more rest periods during the handling process. Pregnant women should not carry out this operation. Persons who are not in good health should seek medical advice prior to commencing any lifting or manual handling operation. Residual risk Following the guidelines given above will reduce any risk to injury. Gledhill Building Products guarantees the StainlessLite cylinder and components against material defect or manufacturing fault for a period of two years from the date of purchase. The two year warranty on the stainless steel inner cylinder will be extended to twenty five years in domestic properties on the registration of the cylinder (see documentation enclosed with the unit). The above product guarantees are valid provided: • • • • • • • • • • It has been installed by a competent installer in accordance with the instructions detailed in our installation manual and all relevant Codes of Practice and Regulations in force at the time of installation. No factory fitted parts have been removed for unauthorised repair or replacement and the product has not been modified - other than by Gledhill. Any replacement parts used should be authorised, approved Gledhill spare parts. The cylinder has only been used for the storage of potable water supplied form the public mains (-max 200mg/litre chloride). It has not been subject to wrong or improper use, left uncared for, or subjected to scale or frost damage. The unit has been serviced annually by a competent, licenced engineer in accordance with the requirement set out in the manual. The Benchmark TM Commissioning Checklist Service Record included in our manual has been completed and updated after each annual service. Any disinfection has been carried out strictly in accordance with BS6700. For heavy use installation where constant usage / reheat is required titanium immersion heaters should be fitted. The registration document enclosed with the unit is completed and returned within 60 days of purchase by the owner. Evidence of purchase and date of supply must be submitted upon making a claim. Guidance in the event of a problem If you have a problem in the first year, please contact the plumber who fitted the unit. After the first year, you should contact the plumber who carries out the annual servicing for you. Action in the event of component failure within warranty period Failed components should be returned via the local authorised supplier. A nominal charge of £30 will be made which is refunded in full by Gledhill on receipt of the original part and proof of purchase. Action in the event of inner vessel cylinder failure within warranty period Since the full diagnosis of cause of failure is usually only possible with a laboratory test environment where a product can be fully assessed and tested, we will require the return of a cylinder which develops a leak for inspection. Providing our expert examination confirms a manufacturing fault or defect, credit will then be raised against the cost of the original cylinder. Please note that a copy of the completed annual service record and commissioning checklist should be submitted with any claim. As a HWA Charter Member we endeavour to provide consumers quality assurance, product satisfaction, and confidence in Gledhill, that we will deliver a service beyond just supplying the product. All persons carrying out this operation must be fully trained and copies of the specific risk assessment made available for inspection and use in their training process.
