Maintenance

Modifications should not be made to this product. Replacement parts, including immersion heaters, should be purchased from Gledhill Building Products Limited, or agents approved by them. 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.

It is essential that these checks be carried out at the time of boiler maintenance by a qualied 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 o 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-ll 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 lift up temperature & pressure relief valve that must not be used for any other purpose or removed.

The cylinder is factory tted with immersion heaters with thermal cut outs. Immersions without thermal cut outs must not be tted.

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:

• Cold water inlet PRV combination valve/expansion relief

• Lift up 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/exible hose

• Technical/user product literature

(Note: Please refer to tables 1 and 2 on pages 6-9 to conrm 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 tted to accommodate the extra expansion volume.

Handling Before Installation

Stainless Lite must be handled with care and stored the correct way up 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 specic manual handling assessment is shown in Appendix B at the rear of this manual.

The Environment

This product has been manufactured using many recyclable materials, including the approved HCFC/CFC free polyurethane foam insulation. At the end of its useful life, it should be disposed of at a Local Authority Recycling Centre, to maximise the products full environmental benets.

General Design Considerations

The cupboard footprint needs to be at least 650mm square for standard units up to 300 litres, 730mm for 400 litre and 575mm for slimline units. 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 ttings on the cylinder should be insulated, and the unit should NOT be xed 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 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.

The pipe connecting the boiler ow to the appliance must not be less than 22mm copper or equivalent.

INSTALLATION

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 conned 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 will function with lower inlet pressures, but this will reduce the performance. For optimum performance, 30L per minute incoming mains ow should be present, however the Stainless Lite will work at lower ow rates, although performance will be affected. Normally Stainless Lite 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.

Model Selection

The suggested Direct model sizes, shown opposite, are based on a typical days hot water use assuming an Economy 7 tari is provided. A reduction of one model size can normally be made with an Economy 10 tariff. When using the Direct models for high specication developments an increase of one model size should be considered.

The suggested model sizes are based on typical hot water usage. For high specication dwellings an increase of one model size should be considered.

Note: Cold supplies to single taps must be

taken from the mains cold water system.

Cold supplies to mixer taps must be taken from the balanced cold water connection on the combination valve.

General Restrictions

a. The highest hot or cold water draw o 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 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 ttings (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 balance 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 t 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. Check the performance requirements of the terminal ttings with regard to ow/

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.

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.

Pipe Layout

In all mains pressure installations it is important to remember that the incoming cold supply must be shared between all terminal ttings. It is important that a 22mm supply is brought to the appliance and a 22mm take-o is continued at least to the bath. If there are two baths, 28mm pipework should be considered. One metre of smaller diameter pipework, or ow restrictors, should be provided on the nal 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.

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 tted, an extra expansion vessel may be necessary. A non-return valve MUST be FITTED near the return connection. No valve or terminal tting 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.

Pressure & Temperature/expansion Relief Valve Pipework

The relief valve should be installed to discharge in accordance with G3 of the Approved Document of the Building Regulations and should be piped to where it is visible, but will not cause danger to persons or damage to materials.

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 nal 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 tted 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 ow 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 Specication 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.

c) Be installed with a continuous fall.

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.

d) It is preferable for the discharge to be visible at both the tundish and the nal point

of discharge but where this is not possible or practically dicult there should be clear visibility at one or other of these locations. Examples of acceptable discharge arrangements are:

1. Ideally below the xed 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 ats, 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, inrm or disabled people, consideration should be given to the installation of an electronically operated device to warn when discharge takes place.

Combination Inlet Group

Combines elements 1, 2 and 3 below.

1. Pressure Reducing Valve - This must be xed 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.

2. Non Return Valve - This is integral with the pressure reducing valve to prevent backow of hot water towards cold water draw o 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.

2 expansion cylinders on 400 litre Models

All 400 litre models are supplied with two 24 litre expansion cylinders. These can be coupled together and tted to the expansion cylinder tapping on the combination inlet valve, or by some other means on the cold/hot water inlet pipework. There must be no valve on the pipe work between the expansion cylinders and the unvented cylinder which could prevent the expansion of the water contained in the unvented cylinder reaching the expansion cylinders.

INSTALLATION

Safety

The safety devices supplied or fitted on an Stainless Lite 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. All parts are available to approved installers from Gledhill Building Products Limited, Sycamore Estate, Squires Gate, Blackpool (Telephone 01253 474402).

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.

Tundish

This is to allow the discharge from any Relief Valve to be seen. It must be tted away from any electrical devices. See page 14 for discharge pipework details.

Page 16

Lift Up Pressure & Temperature Relief Valve

This safety device is also pre-set at the factory and relieves before the temperature reaches 100°C. It is also a Pressure Relief Valve, and is pre-set to 6 bar.

Immersion Heaters

The immersion heaters tted to our units are 3kW 240V ~AC. Check that the mains supply conforms to this, and all external wiring conforms to the most recent revision of the IEE wiring regulations. An Incoloy element is used on this product for standard domestic use and water conditions, use our Titanium elements in all other circumstances, part number SH002.

The immersion heater is tted into the hot water cylinder using an O-ring. After the unit is lled with water check for leaks to determine if the O-ring has sealed and tighten carefully using the appropriate tool. To prevent damage to the O ring do not use excessive force to tighten the immersion heater.

The immersion heater is supplied with a thermostat which has been tested for operation in the cylinder and complies with the European directives for Electromagnetic compatibility and radio interference. It is Rated at 16 Amp 250V ~AC.

Immersion Heater Wiring

INSTALLATION

The immersion thermostat has two terminals A and B. The Live (brown) wire should be connected to terminal A and the Neutral (blue) wire should be connected to terminal B. It has been our experience that Crimp terminals make better connections. The immersion heater must be fully earthed (earth post) and connected via a double pole isolator switch having a contact separation at least 3mm, see diagram opposite.

Danger of electrocution: before making any adjustments to the thermostat isolate the immersion heater from the mains electricity supply at the fuse spur unit.

The immersion heater thermostats incorporate a manual reset safety/overheat cut out thermostat. Should this operate, investigate the cause for the operation cut out before pressing the red reset button labelled safety. If there is no apparent fault adjust the control setting down slightly to prevent nuisance tripping.

If another heat source is used to heat the cylinder and this is allowed to raise the water temperature excessively then the overheat thermostat will trip. This is likely on solar thermal products when the solar thermostats are set at high temperatures.

The Direct cylinder is intended to be heated from an off peak supply using the lowest immersion heater(s) and boosted via the upper immersion heater from an on peak supply. Suitable controllers are available to control this operation eectively.

Solar Thermistors / sensors

Care must be taken to ensure that the solar probes are fully inserted into the pockets provided.

Important

Failure to follow the drain down procedure will invalidate the warranty. (see page 22)

NEVER 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.

In line with good plumbing practice, use of excessive ux should be avoided.

I.V.

Combination Valve

I.V.

If two Stainless Lites are coupled together the secondary inlet and outlet pipes must be balanced. The units must be tted on the same level.

Note: No valves must be tted between the expansion vessel and the storage cylinder(s).

Thermostat Type TSR tted in the Direct cylinders; is supplied set at 62°C ± 3°C. Position 4 is 55°C ± 3°C and position 5 is 68°C ± 3°C.

Thermostat Type TSE tted in the indirect cylinders - is supplied set in position 5 at 60°C ± 4°C.

When ordering a replacement part the TSR thermostat type will be supplied with the immersion heater.

Page 17

Heating/primary Systems

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.

Safety

Stainless Lite is fitted with a Combined Lift Up 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.

Primary Circuit

It is essential that the circuit between the boiler and the Stainless Lite is pumped. The motorised zone valve supplied should be tted adjacent to the unit and controlled by the cylinder thermostat supplied. The thermostat and motorised valve must be wired so that they both switch o should an overheat situation develop. It is important to follow the wiring diagram in the Wiring Section of these instructions.

Sealed Primary Circuit

Any boiler used must be tted 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 eective backow 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 tted with an F&E Cistern.

Gate Valve

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.

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 ow rates and therefore any potential noise problems.

All components in a solar primary system must be marked or identiable 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 tted. 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.

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.

A more detailed diagram of our recommended arrangement for a typical solar system is shown on page 20.

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 ow 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 tted 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 tted 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 tted Overheat thermostats may require resetting in the winter months to enable backup heat sources to heat the cylinder.

Fitting Blending Valves To The Unvented Stainless Lite Appliances

When tting a blending valve to the unvented appliances, it is important that the installation does not contravene the G3, WRC and Health and Safety directives or the manufacturers recommendations. 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.

The diagrams opposite shows how the blending valve can be piped onsite.

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.

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 tted, 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 ow 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 tting a non-return valve or using a thermal trap.

Page 22

Connections can come loose in transit, and all should be checked before installation.

The 90 degree elbow tted on the hot draw o needs to be positioned and tightened by installer.

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 ttings. Allow the system to ll 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 overowing at the tundish, and the valve should seat satisfactorily.

In line with good plumbing practice, use with excessive ux should be avoided. When soldering above the cylinder, ensure ux/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 ush 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 ats 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 appliance is stainless steel, the use of chlorine as the disinfection agent can cause damage unless the appliance is adequately ushed and relled 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.

Remove the lter from the combination inlet group clean and replace. Rell 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.

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 tted correctly.

The boiler/heating systems should be lled and commissioned in accordance with good practice following the guidance in BS 7593:2006/the boiler manufacturers instructions. This includes adequately ushing 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.

This must be completed during commissioning and left with the product to meet the Warranty conditions oered by Gledhill.

IMPORTANT - DRAIN DOWN PROCEDURE

1 Switch o 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

INSTALLATION

COMMISSIONING

Page 23

Your Stainless Lite 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 qualied to work on unvented cylinders. The checks/work needed are listed in the maintenance part of these Instructions.

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.

When initially opening the taps, a small surge in ow 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.

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 owing 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 o, but do not turn o 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 qualied, 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.

INSTALLATION

USER INSTRUCTIONS

Page 24

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 lter

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.

Scale

In hard water areas it is recommended that an in-line scale inhibitor is tted. Reducing the temperature of the stored water will reduce the rate at which scale forms. If the recovery rate is badly aected, 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 tted so that water is owing 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 tted)

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 tted. 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 o 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.

Vast quantities of water are needlessly run o to waste due to Taps, Mixers and Showers discharging ow rates far in excess of the rates required for them to perform their duties.

The contrasting ow rates shown on this leaet clearly illustrate the savings that can be made whilst still providing a good performance.

British made Aquaow Regulators provide constant ow rates by automatically compensating for supply pressure changes between 1 bar & 10 bars.

To facilitate installation into the wide range of plumbing equipment which is

encountered in the U.K, Four Fixing Options are available:-

Options For Showers

1. MXF “DW” Range - For tting behind Fixed Shower Heads or onto Flexible Hoses for Handshowers (preferably onto the inlet end when lightweight hoses are used).

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.

For specic 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:

a. Balance b. Position of back c. Positioning of the arms and body d. The hold e. 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. 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.

c. 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.

d. The hold - Before lifting ensure you have a good hold.

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 at distances, only lift the products when necessary. If in doubt stop and get more help.

Individual capability

Individual capability plays an important part in handling these products. Persons above average build and strength will nd 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.

All persons carrying out this operation must be fully trained and copies of the specic 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.

WARRANTY INFORMATION

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 ve 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 tted parts have been removed for unauthorised repair or replacement and the product has not been modied - 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.

• 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 rst year, please contact the plumber who tted the unit. After the rst 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 conrms 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 condence in Gledhill, that we will deliver a service beyond just supplying the product.
