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

BS6700 and BS7671.

The Building Regulations (England & Wales) require that the installation of a heating appliance be notifi ed to the relevant Local Authority Building Control Department.

From 1st April 2005 this can be achieved via a Competent Person Self Certifi cation

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 BP is not covered by section G3 of the current Building Regulations and is therefore only notifi able to Building Control as part of the domestic water installations.

The PulsaCoil BP 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 specifi cation 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 specifi cation or for the effectiveness of an installation containing one of our products unless we have been specifi cally 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

The PulsaCoil BP shown schematically above is a very highly insulated appliance. As such, the products will allow a pass to be achieved in SAP2005 even in small apartment situations, which is to provide an improved method of supplying mains pressure hot water when using a suitable off peak electric supply/tariff.

Where the water is very hard ie 300ppm (mg/l) and above the optional polyphosphate type, scale inhibitor should be specifi ed at the time of order. However, this will need to be fi tted by the installer at a suitable point in the cold water supply to the appliance.

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. The

SAP calculator takes account of the type of store and various correction factors are included to refl ect the different ways that the hot water and heating operates.

The main feature of the concept is that hot water can be supplied directly from the mains at conventional fl ow rates without the need for temperature and pressure relief safety valves or expansion vessels. This is achieved by passing the mains water through heat exchangers inside the thermal store. The outlet temperature of the domestic hot water is maintained by a thermostatic blending valve.

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 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 fi tted in-line scale inhibitor should be specifi ed at the time of order for hardness levels between 200 and 300 ppm (mg/l).

1. 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. The SAP calculator takes account of the type of store and various correction factors are included to refl ect the different ways that the hot water and heating operates.

2. The fl ow rates are based on a 35°C temperature rise and assume that recommended pressures and adequate fl ow are available at the appliance. The fl ow rate will be reduced if the available water pressure is below that recommended.

3. The domestic hot water outlet temperature is automatically regulated to approximately 52°C at the bath fl ow rate of 18 litres/min recommended by BS

6700. The temperature is user adjustable.

PLAN OF APPLIANCE CONNECTIONS

The PulsaCoil BP units are supplied on an installation base to allow the pipe runs to connect to the appliance from any direction.

It is easier if all pipes protrude vertically in the cut out area shown. Compression or push fi t 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 / overfl ow pipe (if the optional extra ball valve and overfl ow 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 fi lled.

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 BP will operate at mains pressures as low as 1.5 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 fi tted 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 fl ow rates are poor please contact our technical helpline for details of an effective solution.

The hot water flow rate from the PulsaCoil

BP 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 defi ned in BS 6700.

If a water meter is fi tted 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 6700. This could be up to 60ltr/min in some properties.

No check valve or similar device should be fi tted on the cold water supply branch to the PulsaCoil BP.

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”.

Note: The diagram below shows the Top up cistern with ballvalve and warning/overfl ow pipe. The ballvalve/overflow connector can be supplied as an optional extra if required.

However, the standard preferred arrangement is for the cistern to be manually fi lled from a temporary hose connection fi tted with a double check valve.

The cistern must not be fitted more than 6 metres above the PulsaCoil BP appliance itself.

To comply with this requirement the hardness of the mains water should be checked by the installer and if necessary the optional factory fi tted in-line scale inhibitor should be specifi ed 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 specifi ed at the time of order. However, this will need to be fi tted by the installer at a suitable point in the cold water supply to the appliance.

Hot and Cold water System

Pipe Sizing / Materials

The supply of hot and cold mains water directly to a bidet is permitted provided that it is of the over-rim fl ushing type and that a type ‘A’ air gap is incorporated.

To achieve even distribution of the available supply of hot and cold water, it is important in any mains pressure system, that the piping in a dwelling should be sized in accordance with BS 6700. This is particularly important in a large property with more than one bathroom.

Hot and Cold Water System

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 suffi cient for a small 1 bathroom dwelling (depending upon the fl ow 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 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.

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. Please consult Gledhill technical department for further details.

Also a conventional pumped secondary circulation system can be used with this appliance.

baths and showers in 15mm. (1 metre minimum)

4. We would recommend that best results for a balanced system are achieved by fi tting appropriate fl ow 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 fl ow regulators are provided in

Appendix.

It is important that the cold water pipework is adequately separated/protected from any heating/hot water pipework to ensure that the water remains cold and of drinking water quality.

All the recommendations with regard to pipework systems in this manual are generally based on the use of BS/EN Standard copper pipework and fi ttings.

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.

It is also essential that if an alternative pipework material/system is chosen the manufacturer confi rms that the design criteria of the new system is at least equivalent to the use of BS/EN Standard copper pipework and fi ttings.

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 fl ow/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 BP or be the fi rst draw-off 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 fi tted with the necessary check valves to provide back-syphonage protection in accordance with the Water Regulations.

Electrical Installation

The Schematic arrangement of the wiring within the PulsaCoil BP is shown opposite.

The whole of the electrical installation shall be designed and installed by a competent person fully in accordance with the latest edition of the Requirements for Electrical installations

BS 7671.

The PulsaCoil BP 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.

The upper immersion heater is positioned at a level on the PulsaCoil BP to heat the top 50 - 80 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 off-peak controller, eg. Horstman Electronic 7 Controller.

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.

The typical wiring arrangement is shown in figure 1.7. An economy 7 controller (eg

Horstman Electronic 7) is used for a manual boost and automatic off-peak heating of hot water.

If a factory fitted scale inhibitor has been specifi ed, then it should be wired to a permanent supply as shown in fi gure 1.8.

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 fi tted 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/fl oor.

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, 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 fl oor 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. This will be most noticeable if the cupboards are located adjacent to bedrooms, on bulkheads, or at the mid span of a suspended fl oor. 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 BP. The dimensions and clearances are provided in the Technical Data section of this manual. If the top up cistern is sited remotely, the location will need to provide a suitable route for the cold feed expansion pipe as well as the open safety vent pipe. If the ballvalve/overfl ow connector have been ordered (available as optional extras), the location will also need to provide a suitable route and discharge position for the warning/overfl ow pipe and the ballvalve supply from the mains cold water system.

Note: The standard appliance is supplied with a cistern without a ballvalve/ overfl ow for fi lling 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 fi xed 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 ‘fi rst fi x’ pipework should be terminated 50mm above the fi nished fl oor level in accordance with the dimensions provided in the Technical

Data section.

INSTALLATION

It is normally envisaged that the top up cistern will be located in the same cupboard as the PulsaCoil BP appliance itself to maintain a dry roof space.

Electrical Connection - Standard Appliance

The cold feed/open vent pipework (as supplied) should be used to install the top up cistern directly on top of the appliance.

The PulsaCoil BP immersion heater wiring/ connections should be carried out by a competent person to the IEE Requirements for

Electrical Installations BS 7671.

If it is necessary to locate the cistern in any other location, the cold feed/open vent pipework (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.

All the immersion heater terminals are suitably labelled.

Obviously, any pipework in the roof space and the feed and expansion cistern will need to be adequately insulated to protect against frost damage.

Note: Do not attempt the electrical work unless you are competent to carry it out to the above standards.

Combined feed and open pipe arrangements must not be used.

No valves should be fi tted 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 overfl ow/warning pipe (if provided) shall have a continuous fall, be fi tted to discharge clear of the building and be sited so that any overfl ow 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/overfl ow pipe is NOT provided the top up cistern should be fi lled 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 fi tted with a double check valve and removed once the appliance is fi lled.

1) Run the external wiring from the adjacent isolator through the service slot provided in the base of the appliance to the appropriate immersion heaters.

2) You may also run the external wiring from the adjacent isolator through the service slots provided in the base of the appliance to the scale inhibitor PCB terminals as shown in fi gure 1.8.

Note: The appliance pipework should be bonded to earth to comply with the IEE Requirements for Electrical Installations BS 7671.

The store may fi ll more slowly than the feed tank. It is important to check the water level again in the cistern after commissioning and top up if necessary.

Before commencing check that the power source is in accordance with the Site Requirements section of this manual and ensure that it is isolated.

Check the whole of the domestic hot and cold distribution systems for leaks. Fully fl ush and if necessary chlorinate the hot and cold water system in accordance with the recommendations in the Water Regulations and BS 6700.

Please note that the whole of the domestic hot and cold water systems including the appliance must be adequately fl ushed after chlorination. Failure to do this can cause damage to the exchangers/immersion heaters etc. If there are any doubts regarding this or the quality of the water being used to fi ll the PulsaCoil BP appliance an inhibitor such as Fernox MBI or Sentinel X100 should be added to the appliance when fi lling in line with the manufacturers instruction for these products.

It is most important to check that the top up tank is fi lled up to the water level shown on the label, if it is a manual fi ll model. If the optional level gauge has been provided, the level will be shown by the red fl oat.

If a ballvalve is provided, turn down the servicing valve once the system is fi nally fi lled to the point where the warning/overfl ow pipe will cope with the discharge arising from a ballvalve failure.

If an overfl ow is not provided ensure the temporary fi lling hose is isolated and removed from its connection to the cold water supply.

It is essential that all systems function properly for optimum performance and if necessary, adjust the thermostatic blending valve to control the hot water outlet temperature between 50°C-55°C.

To achieve this the fl ow rate from each tap should be checked and a suitable number of taps run simultaneously to check the impact of this on the fl ow rate at individual taps.

We recommend that fl ow regulators are provided for each tap/terminal fi tting to ensure that the available fl ow is shared evenly - See Appendix A for further details.

This product is covered by the ‘Benchmark’ scheme and a commissioning/service record is included in this manual. This must be completed during commissioning and left with the product to meet the Warranty conditions offered by Gledhill.

Important Do’s and Don’ts Annual Service

1. DO check the incoming mains water pressure. The preferred range of mains pressure is 2 -3 bar.

2. DO check the fl ow 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 NOT switch on the immersion heaters until you have checked that the appliance is full of water ie there is water in the top up cistern.

5. DO check the water level is correctly set in the top up cistern when cold and (if fi tted) that there is no discharge from the overfl ow when the appliance is up to temperature.

6. DO check that the immersion heater thermostats are set at approx 75°C (factory set).

7. DO insulate any exposed hot water pipework in the PulsaCoil BP cupboard and appliance.

8. If the ballvalve in the F & E cistern is permanently connected to the mains cold water supply DO plumb the overfl ow/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).

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 BP is necessary.

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 specifi cation.

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 using the ‘Speed Spares’ service, or through any of the larger plumbers merchants/ specialist heating spares suppliers.

These instructions should be placed along with the component manufacturers instructions in the pocket provided on the top of the appliance. The appliance should be left with the front panel fi tted and screwed in position.

Help and advice is also available from the

Technical Helpline on 0906 611 0005. Please note this is a premium rate line and will be charged accordingly.

However, all components are readily accessible and can be changed quickly and easily by the installer using common plumbing/electrical practice.

However all maintenance work on the PulsaCoil

BP appliance must be carried out by a competent trades person.

MANUAL HANDLING OF APPLIANCE PRODUCTS

Description

Manual handling means any transporting or supporting of a load (including lifting, putting down, pushing, pulling, carrying or moving) by hand or bodily force.

Scope

This assessment will cover the largest unit within each product range manufactured by Gledhill.

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 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. a. b. c. d. e.

Individual capability

The lift, key factors in safe lifting are: a. b.

Balance

Position of back

Positioning of the arms and body

The hold

Taking the lead for team lifts

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.

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.

Pregnant women should not carry out this operation.

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.

Persons who are not in good health should seek medical advice prior to commencing any lifting or manual handling operation.

Residual risk c. d.

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.

Following the guidelines given above will reduce any risk to injury.

The hold - Before lifting ensure you have a good hold. Two handles are provided on Appliance products at the top rear side, these allow one or two persons to have a purposely-designed hold at the top of the appliance to ensure easy lifting at the top of 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.

Further guidance on Manual Handling can be obtained from the Health and

Safety Executive. Manual Handling

Operations Regulations 1992.
