DESIGN Any water distribution system/installation must comply with the relevant recommendations of the current version of the Regulations and British Standards listed below:Building Regulations Requirements for Electrical Installations Water Regulations Manual Handling Operations Regulations British Standards BS EN 806:1-5: BS EN 8558:2011 The Building Regulations (England & Wales) require that the installation of a heating appliance be notified to the relevant Local Authority Building Control Department. From 1st April 2005 this can be achieved via a Competent Person Self Certification Scheme as an option to notifying the Local Authority directly. Similar arrangements will follow for Scotland and will apply in Northern Ireland from 1st January 06. A suitably competent trades person must install the PulsaCoil and carry out any subsequent maintenance/repairs. In fact the appliance front cover is secured by 2 screws and this should only be removed by a competent trades person. The manufacturer’s notes must not be taken as overriding statutory obligations. The PulsaCoil Stainless is not covered by section G3 of the current Building Regulations and is therefore only notifiable to Building Control as part of the domestic water installations. The PulsaCoil Stainless is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience or knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. The information in this manual is provided to assist generally in the selection of equipment. The responsibility for the selection and specification of the equipment must however remain that of the customer and any Designers or Consultants concerned with the design and installation. Please Note: We do not therefore accept any responsibility for matters of design, selection or specification or for the effectiveness of an installation containing one of our products unless we have been specifically requested to do so. All goods are sold subject to our Conditions of Sale, which are set out at the rear of this manual. In the interest of continuously improving the PulsaCoil range, Gledhill Building Products Ltd reserve the right to modify the product without notice, and in these circumstances this document, which is accurate at the time of printing, should be disregarded. It will however be updated as soon as possible after the change has occurred. Page 3 INTRODUCTION DESIGN 1. Bottom (Off-Peak) immersion heater (1H_1) 2. Top (On-Peak) immersion heater (IH_2) 3.

An important feature of the concept is that hot water can be supplied directly from the mains at conventional flow rates without the need for temperature and pressure relief safety valves or expansion vessels. This is achieved by passing the mains water through a plate heat exchanger. The outlet temperature of the domestic hot water is maintained by a printed circuit control board, which controls the speed of the pump circulating the primary water from the store through the plate heat exchanger. Because this product does not require a safety discharge from a temperature and pressure relief valve, any installations will be easy to incorporate into the building and will not suffer from the problems associated with using PVCu soil stacks to take the discharge from unvented cylinders. The heat losses from thermal stores should not be directly compared with heat losses from unvented or vented cylinders because they are treated differently in SAP. This is because the unvented and vented cylinders are tested at 65°C and the thermal store at 75°C.

It is easier if all pipes protrude vertically in the cut out area shown. Compression or push fit connections can be used. All pipe positions are approximate and subject to a tolerance of +/- 10mm in any direction. Space will also be required for a 15mm cold water supply and a 22mm warning / overflow pipe (if the optional extra ball valve and overflow connector have been specified. If a warning/overflow pipe is NOT provided the F&E Cistern should be filled from a temporary hose connection incorporating a double check valve. This can be from a temporary hose connection supplied from a cold water tap or a permanent cold branch provided adjacent to the Top up Cistern. The temporary connection must be removed once the appliance is filled. Note: All dimensions are shown in mm and are to the centre line of the pipework. 103 156 Connection Details/Dimensions For Bottom Of Unit 70 558 546 35 Hot Water Outlet (18mm/22mm) Mains Cold Water Inlet (15mm/22mm) Figure 1.4 TECHNICAL DATA Page 8 DESIGN Hot and Cold Water System General A schematic layout of the hot and cold water services in a typical small dwelling is shown below. PulsaCoil Stainless will operate at mains pressures as low as 1 bar and as high as 5 bar although the recommended range is 2-3 bar dynamic at the appliance. It is also important to check that all other equipment and components in the hot and cold water system are capable of accepting the mains pressure available to the property. If the mains pressure can rise above 5 bar or the maximum working pressure of any item of equipment or component to be fitted in the system, a pressure limiting (reducing) valve set to 3 bar will be required. If you encounter a situation where the water pressure is adequate but flow rates are poor please contact our technical helpline for details of an effective solution. Note : Each Pulsacoil Stainless is fitted with a strainer and flow regulator on the cold mains supply connection. If the supply pressure is less than 2 bar or if all taps are provided with flow regulators the flow regulator on the cold inlet should be removed. No check valve or similar device should be fitted on the cold water supply branch to the PulsaCoil Stainless. The Building Regulations L1A: New dwellings/L1B: Existing dwellings and the requirements set out in the Domestic Heating Compliance Guide specify that “where the mains water hardness exceeds 200ppm provision should be made to treat the feed water to water heaters and the hot water circuit of combination boilers to reduce the rate of accumulation of lime scale”. To comply with this requirement the hardness of the mains water should be checked by the installer and if necessary the optional factory fitted in-line scale inhibitor should be specified at the time of order for hardness levels between 200 and 300 ppm (mg/l). Where the water is very hard ie 300ppm (mg/l) and above the optional polyphosphate type, inhibitor should be specified at the time of order. However, this will need to be fitted by the installer at a suitable point in the cold water supply to the appliance. The hot water flow rate from the PulsaCoil Stainless is directly related to the adequacy of the cold water supply to the dwelling. This must be capable of providing for those services, which could be required to be supplied simultaneously, and this maximum demand should be calculated using procedures defined in BS EN 806:1-5: BS EN 8558:2011. If a water meter is fitted in the service pipe, it should have a nominal rating to match the maximum hot and cold water peak demands calculated in accordance with BS EN 806:1-5: BS EN 8558:2011. This could be up to 60ltr/min in some properties. Note: The diagram below shows the top up cistern with ballvalve and warning/overflow pipe which can be supplied as an optional extra if required. However, the standard preferred arrangement is for the cistern to be manually filled from a temporary hose connection fitted with a double check valve. The cistern must not be fitted more than 10 metres above the PulsaCoil Stainless appliance itself.

This is particularly important in a large property with more than one bathroom. However, the following rule of thumb guide lines should be adequate for most smaller property types as long as water pressures are within the recommended range. 1. A 15mm copper or equivalent external service may be sufficient for a small 1 bathroom dwelling (depending upon the flow rate available), but the minimum recommended size for new dwellings is 22mm (25mm MDPE). 2. The internal cold feed from the main incoming stop tap to the PulsaCoil Stainless should be run in 22mm pipe. The cold main and hot draw-off should also be run in 22mm as far as the branch to the bath tap. 3. The final branches to the hand basins and sinks should be in 10mm and to the baths and showers in 15mm (1 metre minimum). 4. We would recommend that best results for a balanced system are achieved by fitting appropriate flow regulators to each hot and cold outlet. This is particularly relevant where the water pressures are above the recommended water pressure range. Details of suitable flow regulators are provided in Appendix A. All the recommendations with regard to pipework systems in this manual are generally based on the use of BS/EN Standard copper pipework and fittings. However, we are happy that plastic pipework systems can be used in place of copper internally as long as the chosen system is recommended for use on domestic hot and cold water systems by the manufacturer and is installed fully in accordance with their recommendations. This is particularly important in relation to use of push fit connections when using the optional flexible hose kits - see installation section of this manual. It is also essential that if an alternative pipework material/system is chosen the manufacturer confirms that the design criteria of the new system is at least equivalent to the use of BS/EN Standard copper pipework and fittings. Hot and Cold Water System If the length of the hot water draw-off pipework is excessive and the delivery time will be more than 60 seconds before hot water is available at the tap, you may wish to consider using trace heating to the hot water pipework such as the Raychem HWAT system. Also a conventional pumped secondary circulation system (shown below) can be used with any model of the PulsaCoil. Hot water outlets PulsaCoil Stainless Flow switch Plate heat exchanger Pump isolation valves Control stat Cold water sensor Inline filter & flow regulator Single check valve Cold water inlet Pipework length and diameter to suit property demands Single check valve Secondary circulation pump Pipework length and diameter to suit recirculation flow rate approx 1-2 l/min Potable water expansion vessel TECHNICAL DATA Page 10 It is important that the cold water pipework is adequately separated and protected from any heating from the hot water pipework to ensure that the water remains cold and of drinking water quality. If secondary circulation is used, there is a possibility that excessively hot temperatures may be experienced in the hot water supply pipework due to the blending valve not being able to mix with cold water because the water is always supplied hot. A pipe thermostat is incorporated in the circuitry which cuts the supply to the pump when the water in the return pipe reaches the set temperature of the blending valve. Secondary circulation pipework must be insulated to prevent energy loss in both heated and unheated areas. Taps/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. The shower head provided must also be suitable for mains pressure supplies. However, if it is proposed to use a ‘whole body’ or similar shower with a number of high flow/ pressure outlets please discuss with the Gledhill technical department. The hot water supply to a shower-mixing valve should be fed wherever practical directly from the PulsaCoil Stainless or be the first drawoff point on the hot circuit. The cold supply to a shower-mixing valve should wherever practical be fed directly from the rising mains via an independent branch. The shower must incorporate or be fitted with the necessary check valves to provide back-syphonage protection in accordance with the Water Regulations. The supply of hot and cold mains water directly to a bidet is permitted provided that it is of the over-rim flushing type and that a type ‘A’ air gap is incorporated.

The PulsaCoil Stainless appliance is provided with two side entry 3kW immersion heaters and has been designed to generally operate with an off peak supply. The lower immersion heater heats the whole of the contents and is normally connected to the off peak supply. Immersion (On Peak) The upper immersion heater is positioned at a level on the PulsaCoil Stainless to heat the top 66 - 111 litres of the store - see Technical Data Table on page 5. This is connected to the unrestricted on peak supply and is switched manually by the householder using the button on the boost controller. PulsaCoil Stainless Schematic Wiring Diagram The size of the appliance and the need to use the on peak boost facility is reduced if a better off peak tariff can be agreed with the electrical supply company - see Model Selection Guide on page 5.

In all cases the two switches/isolators must be clearly labelled for the householders use. INSTALLATION The appliance is designed to be installed in an airing/cylinder cupboard and the relevant minimum dimensions are provided in the Technical Data section of this manual. Because of the ease of installation we recommend that the cupboard construction is completed and painted before installation of the appliance. The cupboard door can be fitted after installation. If the unit needs to be stored prior to installation it should be stored upright in a dry environment and on a level base/floor. Installation and maintenance access is needed to the front of the appliance and above the Top up cistern. See the Technical Data section of this manual for further details. The minimum dimensions contained in the Technical Data section of this manual allow for the passage/connection of pipes to the appliance from any direction as long as the appliance is installed on the installation base provided. If the installation base is not used extra space may be needed to allow connection to the pipework and the whole of the base area should be continuously supported on a material which will not easily deteriorate if exposed to moisture. The floor of the cupboard needs to be level and even and capable of supporting the weight of the appliance when full. Details of the weight when full is provided in the Technical Data section of this manual. The appliance is designed to operate as quietly as practicable. However, some noise (from pumps etc) is inevitable when hot water is being used. This will be most noticeable if the cupboards are located adjacent to bedrooms, on bulkheads, or at the mid span of a suspended floor. Some noise may also be experienced from the immersion heaters as the store approaches its design temperature. Cupboard temperatures will normally be slightly higher than in a conventional system and the design of the cupboard and door will need to take this into account. No ventilation is normally required to the cupboard. The separate Top up cistern will need to be located on top of the appliance or at high level in the cupboard housing the PulsaCoil Stainless. The dimensions and clearances are provided in the Technical Data section of this manual. The location will need to provide a suitable route for the cold feed expansion pipe as well as the open safety vent pipe. The location will also need to provide a suitable route and discharge position for the warning/overflow pipe and the ballvalve supply from the mains cold water system (if provided) if these have been ordered as an optional extra. Note: The standard appliance is supplied with a cistern without a ballvalve/ overflow for filling manually. An electrical supply must be available which is correctly earthed, polarized and in accordance with the latest edition of the IEE requirements for electrical Installations BS 7671. The electrical mains supply needs to be 230V/50Hz. The sizes/types of electrical supplies must be as detailed in System Details section of this manual. A means for disconnection from the supply mains having a contact separation in all poles that provides full disconnection under over voltage category III conditions must be incorporated in the fixed wiring in accordance with the wiring rules. This shall be located within 1m of the appliance and only serve the appliance. The hot and cold water ‘first fix’ pipework should be terminated 50mm above the finished floor level in accordance with the dimensions provided in the Technical Data section of this manual.

The appliance is supplied shrink wrapped on a timber installation base with the F&E cistern on top of the unit. Carrying handles are also provided in the back of the casing. The appliance should be handled carefully to avoid damage and the recommended method is shown above. Note: Although the above guidance is provided 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. HANDLING When lifting the unit work with someone of similar build and height if possible. Choose one person to call the signals. Lift from the hips at the same time, then raise the unit to the desired level. Move smoothly in unison. Larger units may require a team lift. A specific manual handling assessment is shown in Appendix C at the rear of this manual. 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. Before installation the site requirements should be checked and confirmed as acceptable. The plastic cover and protective wrapping should be removed from the appliance and the installation base (provided) placed in position. The appliance can then be lifted into position in the cupboard on top of the base and the front panel removed by unscrewing the 2 screws and lifting the door up and out, ready for connection of the pipework and electrical supplies. The feed and expansion cistern support shall be installed ensuring that the base is fully supported, the working head of the appliance is not exceeded and the recommended access is provided for maintenance - see the Technical Data section of this manual for details. Page 15 INSTALLATION INSTALLATION Pipework Connections The position of the pipework connections is shown opposite. The exact location dimensions are listed in the Technical Data section of this manual. All the connections are also labelled on the appliance. It is essential that the pipework is connected to the correct connection. Connections A and B are plain ended copper pipe. Connection C and D compression fittings. Connection E is RC½ (½ in BSPT internal) A B A B C D E - 22mm Safety open vent 22mm Cold feed/expansion 22mm Incoming mains cold water 22mm Domestic hot water ½” Drain tap connection Note: The safety open vent and cold feed/ expansion must be connected to the top up cistern using the pipework assembly provided. Do not alter or connect any pressure-relief device to the vent pipe of this water heater. All factory made joints should be checked after installation in case they have been loosened during transit. The fittings for the top up cistern should be installed following the instructions provided and the cistern fitted on its supports/top of the appliance. The cold feed/expansion and safety open vent should be installed between the appliance and the top up cistern. D C E Figure 1.6 INSTALLATION Page 16 INSTALLATION Feed And Open Vent Pipe Electrical Connection - Standard Appliance It is normally envisaged that the top up cistern will be located in the same cupboard as the PulsaCoil Stainless appliance itself to maintain a dry roof space. The external wiring/connections should be carried out by a competent person to BS7671. The arrangement of the internal wiring is shown on page 14. The cold feed/open vent pipework assembly (as supplied) should be used to install the top up cistern directly on top of the appliance. If it is necessary to locate the cistern in the roof space (or on a higher floor) the cold feed/open vent pipework assembly (as supplied) should be used to connect to the top up cistern and pipework site run by the installler to connect this to the appliance. Obviously, any pipework in the roof space and the feed and expansion cistern will need to be adequately insulated to protect against frost damage. Combined Feed And Open Pipe Arrangements Must Not Be Used. No valves should be fitted in the safety open vent which must be a minimum of 22mm copper pipe or equivalent throughout its length. The mains cold water supply to the ballvalve (if provided) shall be provided with a suitable servicing valve. The overflow/warning pipe (if provided) shall have a continuous fall, be fitted to discharge clear of the building and be sited so that any overflow can be easily observed. It shall also be installed in a size and material suitable for use with heating feed and expansion cisterns in accordance with BS 5449 (e.g 22mm copper) and should not have any other connections to it. Note: If a warning/overflow pipe is NOT provided the top up cistern should be filled from a temporary hose connection supplied from any cold water tap or from a permanent cold branch provided adjacent to the top up cistern. The temporary hose must be fitted with a double check valve and removed once the appliance is filled. The store may fill more slowly than the feed tank. It is important to check the water level again in the cistern after commissioning. All the terminals are suitably labelled. Note: Do not attempt the electrical work unless you are competent to carry it out to the above standards. Before commencing check that the power source is in accordance with the Site Requirements section of this manual and ensure that it is isolated as shown in the System Details section. Run the external wiring from the adjacent isolator through the service slot provided in the base of the appliance. Clamp the cables in the grips provided and ensure all cables are routed to avoid hot surfaces. Note: The appliance pipework should be bonded to earth to comply with the IEE Requirements for Electrical Installations BS 7671. Before switching on the electrical supply check all the factory made terminal connections to ensure they have not become loose during transit. Cold feed / open vent pipework (as supplied) Interconnecting Pipework (By Installer) PulsaCoil Figure 1.7 Page 17 INSTALLATION INSTALLATION Open the incoming stop valve and fill the domestic mains cold and hot water systems including the PulsaCoil Stainless appliance. Check the water level in the top up cistern and if a ballvalve is fitted adjust if necessary. Check the whole of the domestic hot and cold distribution systems for leaks. Fully flush and if necessary chlorinate the hot and cold water system in accordance with the recommendations in the Water Regulations and BS EN 806:1-5: BS EN 8558:2011. Please note that the whole of the domestic hot and cold water systems including the appliance must be adequately flushed after chlorination. Failure to do this can cause damage to the plate heat exchanger/immersion heaters etc. If there are any doubts regarding this or the quality of the water being used to fill the PulsaCoil appliance an inhibitor such as Fernox MBI or Sentinel X100 should be added to the appliance when filling in line with the manufacturers instruction for these products. Check that the top up tank is filled up to the water level shown on the label. If it is a manual fill model, this is most important. If a ballvalve is provided, turn down the servicing valve once the system is finally filled to the point where the warning/overflow pipe will cope with the discharge arising from a ballvalve failure. If an overflow is not provided ensure the temporary filling hose is isolated and removed from its connection to the cold water supply. It is essential that all systems function properly for optimum performance. To achieve this the flow rate from each tap should be checked and a suitable number of taps run simultaneously to check the impact of this on the flow rate at individual taps. We recommend that flow regulators are provided for each tap/terminal fitting to ensure that the available flow is shared evenly - See Appendix A for further details. Commissioning the PulsaCoil Control System It can be checked that the boost immersion heater is drawing current by use of a clamp meter on the live supply when boost is active or by interrogating the printed circuit control board in accordance with the instructions in the fault finding section of this manual. If an off peak supply is available at the time the appliance is switched on. Its operation can be checked with a clamp meter as described above. If the appliance has been connected with the polarity incorrect it will not operate at all. See the fault finding section of the manual for further details. Run a tap and using a digital thermometer check that the temperature of the hot water is about 52°C. This temperature is factory set and is independent of the store temperature assuming the store is above 55°C and typical hot water flow rates of 6-15l/min are being drawn. At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document. This must be completed during commissioning and left with the product to meet the Warranty conditions offered by Gledhill. COMMISSIONING Page 18 Basic pump operation testing In order to confirm that the pump is operational, and that all air has been cleared from the pump circuit pipe work, including the PHE. Perform the following actions. 1. Ensure that the unit is full of water 2. Ensure that the primary pipework to the PHE and the PHE itself are bled of air 3. Open hot water tap 4. The pump should then run and hot water will be delivered through the tap INSTALLATION Circulating fluid in thermal store pipework • The PulsaCoil Stainless and the thermal store pipework must have completed filling prior to switching the electricity supply to the PWM controller PCB. If there is no water in these pipes then there may be significant wear on the PWM pump. • This can be confirmed by - Checking the thermal store pipework servicing valves are open - Loosening the connection points on the thermal store pipework in a systematic manner and checking for water presence. - Confirming that the feed and expansion tank has completed filling and the servicing valve is open. Cold mains water supply to plate heat exchanger and hot water taps • Confirm that the CW mains stop valve is open • Open all HW taps and confirm that the water runs freely and that any air is bled from the DHW system • Determine the maximum flow rate obtained and record • 15l/min for all PulsaCoil products currently limited with a flow restrictor • If flow rate not as expected determine the cause and rectify - clean inline strainer - check the flow restrictor is present and not blocked. It is located in the top of the inline strainer Power on • Switch on the Local fuse spur and observe the PWM pump • The green LED will flash showing the pump has a power supply and is in standby mode. • Open a HW tap and observe the PWM pump • The green LED will be constantly lit showing the pump has a power supply and is running to generate HW NOTE: -The thermal store will only produce hot water when it is hot enough. A mid 40°C thermal store temperature will provide some hot water, higher thermal store temperatures will provide more. Inline scale inhibitor (if fitted) • Check power supply • PWM Controller PCB supplies a maximum of 12vDC/300mA to the Scale inhibition board. (From J3) • Check dip switches set correctly • The correct settings for tube diameter 22mm is switch no. 3 on. • Switch no. 4 can be either on or off. • If the switch no. 4 is turned on the output electromagnetic field is generated harmoniously otherwise the field is generated inharmoniously. Page 19 INSTALLATION REVIEW INSTALLATION Important Do’s and Don’ts Annual Servicing 1. DO check the incoming mains water pressure. The preferred range of mains pressure is 2 -3 bar. 2. DO check the flow rate of the incoming cold water main is adequate to meet the maximum hot and cold water simultaneous demands. 3. DO check that all connections are in accordance with the labelling on the thermal store. 4. DO check the water level is correctly set in the top up cistern when cold and if fitted that there is no overflow when the appliance is up to temperature. 5. DO check that the control thermostats switch the immersion heaters off at the correct set point i.e. approx 73°C. 6. DO insulate any exposed hot water pipework in the PulsaCoil cupboard. 7. If the ballvalve in the F & E cistern is permanently connected to the mains cold water supply DO plumb the overflow/warning pipe in a 20mm internal diameter pipe and ensure it discharges in a conspicuous external position. Use a material which is suitable for use with heating F & E cisterns in accordance with BS 5449 (such as copper). 8. Once the appliance is filled and commissioned DO leave the electricity switched on to the appliance to ensure the automatic pump run facility can operate to prevent the pump sticking. 9. DO ensure that the functioning and control of the system is explained to the occupant. 10. DON’T place any clothing or other combustible materials against or on top of this appliance. No annual servicing of the PulsaCoil Stainless is necessary. Help and advice is also available from the Technical Helpline on 01253 474584. The front panel should then be refitted. However, if required, the operation of the controls and a hot water performance test can be carried out to prove the appliance is working satisfactorily and within its specification. If it is decided to carry out the above tests the water level in the top cistern should also be checked and if necessary topped up. Changing Components Free of charge replacements for any faulty components are available from Gledhill during the in-warranty period on return of the faulty part (normally 12 months). After this, spares can be obtained direct from Gledhill Spares or through any of the larger plumbers merchants/specialist heating spares suppliers. However, all components are readily accessible and can be changed quickly and easily by the installer using common plumbing/electrical practice. Note: All maintenance work on the PulsaCoil appliance must be carried out by a competent trades person. Note: The pump is a PWM 2 pump. It has 2 cables, one 3 core power cable and one 2 core signal cable. These cables are part of the control box.
