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. Unvent ed 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 qualiﬁ 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 off and remove and clean the strainer element in the Pressure Reducing Valve.

4. Check the charge pr essure in the expansion vessel and repressurise if required

5. Re-ﬁ ll the system and ensure that all relief valves have re-seated.

6. The Benchmark log book supplied should be updated at each service.

7. Check the water pressure downstream of the combination valve is 2.25 bar in static condition.

8. Check and if necessar y, descale the heat exchanger in hard water areas ie. above 200ppm (mg/l).

Note:

The cylinder is factory ﬁ tted with a temperature & pressure relief valve that must not be used for any other purpose or removed.

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

Manufacturer: Gledhill Building Products Ltd

Maximum inlet pressure to Pressure Reducing Valve 12 bar Operating pressure (PRV setting) 2.2 bar Expansion Relief Valve setting 4.5 bar Maximum primary working pressure 3.5 bar Opening pressure of T & P Relief Valve 6 bar Opening temperature of T & P Relief Valve 95°C Energy cut-out thermostat setting 80°C Immersion heater: Rating: 3kW, 240V AC

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 combination valve

• Expansion relief/PRV combination valve

• Temperature and pressure relief valve

• Control thermostat

• Energy cut-out thermostat

• Energy cut-out motorised valve (indirects only)

• Tundish

• 3Kw Immersion heater

• Expansion vessel/mounting bracket/ﬂ exible hose

• Technical/user product literature (Note: Two immersion heaters are supplied with the direct Stainless Lite)

In any situation where the volume of heated pipew ork (eg. secondary circulation pipes or manifold pipework for multiple units) exceeds 10 litres, then an additional expansion vessel must be ﬁ 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 speciﬁ c manual handling assessment is shown in Appendix B at the rear of this manual.

Stainless Lite direct is an electrically heated, unvented hot water storage cylinder designed primarily for use with off peak electrical supplies.

It is supplied ﬁ tted with two 3kW immersion heaters which are BEAB approved for safety as recommended by the Electricity Council.

A high efﬁ ciency coil is positioned in the lower part of the Stainless Lite vessel to ensure maximum beneﬁ t of solar gain energy.

Stainless Lite direct models are listed in Table 1 on Page 6 & 7.

Stainless Lite Indirect Solar

When used with a sealed heating system the boiler must incorporate its own energy cut-out overheat thermostat.

A high efﬁ ciency second solar coil is positioned below the primary coil to ensure maximum beneﬁ t of solar gain energy.

Stainless Lite indirect models are listed in

Table 1 on Page 6 & 7.

Note: The cold supply elbow c/w drain tapping must be ﬁ tted as shown in ﬁ gs 1, 2, 3 and 4. A ﬂ exible hose can then be connected to the drain tapping and, providing the hose runs below the lowest level of the cylinder, then all the water contents can be drained out by syphonic action.

INSTALLATION

General Design Considerations

The cupboard footprint needs to be at least 650mm square.

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 hav e a minimum fall of 1 : 200 from the unit to a safe discharge point. All exposed pipework should be insulated and the unit should NOT be ﬁ xed in a location where the contents could freeze.

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

Mains Water Supply

Existing properties with a 15mm supply will be satisfactory provided the local mains pressure is good, but should be confined to single bathroom properties. F or 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 minimum recommended static pressure to operate a Stainless Lite domestic system is 3 bar. There should be a ﬂ ow of at least 30 litres per minute or above available into the property . 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 BS6700.

Model Selection

The suggested Direct model sizes, shown opposite, are based on a typical days hot water use assuming an Economy 7 tariff is provided. A reduction of one model size can normally be made with an Economy 10 tariff.

When using the Direct models for high speciﬁ cation developments an increase of one model size should be considered.

Where selecting a solar model, it is important to check the dedicated solar volume (shown in table 1 on page 7) is suitable for the total ﬂ oor area of the dwelling to ensure compliance with Building Regulations. The maximum ﬂ oor area of the dwelling permitted for the models is shown opposite.

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

a. The highest hot or cold water draw off point should not exceed 10 metres above

the Pressure Reducing Valve.

b. An ascending spray type bidet or any other appliance with a Class 1 back-syphonage

risk requiring a type A air gap should not be used.

c. Stainless Lit e should not be used wher e 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 ﬁ ttings (other than a dual outlet type) is not taken

from the balanced supply the system will become over pressuriz ed 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 nec essary to ﬁ 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 ﬁ ttings with regard to ﬂ ow/

pressure are suitable.

Shower Fittings

Aerated taps are recommended to prevent splashing . Any type of shower mixing valv e 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 ﬁ ttings. It is important that a 22mm supply is brought to the appliance and a 22mm take-off is continued at least to the bath. If there are two baths, 28mm pipework should be considered. One metre of smaller diameter pipework, or ﬂ ow restrictors, should be provided on the ﬁ nal connection to all outlets so as to balance the water available. In any event the distribution pipework should generally be in accordance with EN806:1.

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 ﬁ tted with a secondary return tapping as standard (see table 1 for details). If fitted, an extra expansion vessel may be necessary. A non-return v alve MUST be FITTED near the return connection. No v alve or terminal ﬁ tting should be installed between the non return valve and the cylinder. (See schematic arrangement on page 13.)

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 ﬁ 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 ﬁ tted as close as possible and within 500mm 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 ﬂ ow resistance. Refer to the table and the worked example.

An alternative approach for sizing

discharge pipes would be to follow BS6700 Speciﬁ 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 dischar ge pipe (D2) having 4 elbows and length of 7m from the tundish to the point of discharge.

From T able 1: 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.

INSTALLATION

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

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

1. Ideally below the ﬁ 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 ar e 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. int o 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 ser ves a number of discharges, such as in blocks of ﬂ 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 dw ellings occupied by blind, inﬁ rm or disabled people, consideration should be giv en to the installation of an electronically operated device to warn when discharge takes place.

Safety

The safety devices supplied or ﬁ tted on an Stainless Lite are selected for their suitability for the temperatures and pressures involv ed. They must not be changed, removed or by-passed and it is essential that only genuine replacement parts supplied or approved by Gledhill Building Products Limited are used. This includes the immersion heaters, which must incorporate an energy cut-out. All parts are available to approv ed installers from Gledhill Building Products Limited, Sycamore Estate, Squires Gate, Blackpool (Telephone 01253 474402).

Temperature/pressure 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

These are 3kW 240V AC heaters and incorporate a thermostat and a manually reset energy cut-out which operates at 80°C. They have incalloy elements to pr olong their life expectancy in aggressive water conditions.

Two immersion heaters are ﬁ tted to all direct models and the indirect 250 and 300 models. All other models have one immersion heater ﬁ tted. Where it is intended that units are ﬁ tted to offpeak circuits, then suitable controllers such as the Horstmann off peak electric time controller will be required. External wiring to the immersion heaters must be in accordance with the relevant IEE Wiring Regulations and the cir cuit must be protected by a suitable fuse and a double pole isolating switch.

The correct method of terminating the wiring to the immersion heater is shown opposite.

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 ﬁ tted away from any electrical devices. See page 13 for discharge pipework details.

Safety

The immersion heaters must be earthed and they must be isolated from the mains before the cover is removed on every occasion. Replacement immersion heaters should be obtained from Gledhill Building Products Limited.

Control/overheat Dual Thermostats

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

Page 15

INSTALLATION

Heating/primary Systems

The boiler and primary/heating systems should be sized and installed in accordance with BS

5449.

Safety

Stainless Lite is fitted with a Combined Temperature/Pressure Relief Valve to cope with any increase in system temperature and pressure above the design limitations, when used with boilers up to 45kW output, which is the maximum allowed by section G3 of the Building Regulations. The primary water temperatures should be controlled as outlined below.

Primary Circuit

It is essential that the circuit between the boiler and the Stainless Lite is pumped. The motorised zone valve supplied should be ﬁ 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 off 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 ﬁ 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 effective backflow prevention device is permanently connected at the inlet to the circuit and the temporary connection is removed after use.

Alternatively, a CA devic e 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 ﬁ tted with an F&E Cistern.

All components in a solar primary system must be marked or identiﬁ able in such a way that their design pressure and temperature can be readily determined.

A safety device (pressure relief valve) to control the risk of over-pressure in system components should be ﬁ tted. A termination from a safety pressure device should minimise the risk of damage to persons or materials. Suitable locations are a high temperature receptacle, an internal gully or else issue 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 nondeformable construction, without an y possibility of restriction or disclosure by any other ﬁ tted component.

A more detailed diagram of our recommended arrangement for a typical solar system is shown on page 17.

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 Delta Sol controller.

The pocket provided for the Dual Thermostat also includes the facility to accommodate an 8mm diameter sensor which, with the sensor located in the solar collector (or in the ﬂ ow pipe immediately adjacent to the collector), will provide the information required by the Delta Sol BS controller.

Note: If the motorised valve is not used then any factory built hydraulic station for solar use MUST be ﬁ tted with suitable non-return valves in both flow and return pipes to prevent gravity circulation when the pump is not running.

COMMISSIONING

INSTALLATION

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

Ensure that the immersion heater setting is 60°C and that the wiring is in accordance with the diagram.

Check the pressure on the air side of the expansion vessel = 2.2bar. This must be done when the volume in the cylinder is cold.

Check that the drain cock is closed, and open all the cold and hot water taps and other terminal ﬁ ttings. Allow the system to ﬁ ll with water , and t o 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 overﬂ owing at the tundish, and the valve should seat satisfactorily.

Allow the cylinder to heat to normal working temperature, then thoroughly ﬂ 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 ﬂ ats etc., the hot and cold water system will need to be disinfected in accordance with BS6700 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 ﬂ ushed and reﬁ 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 above reasons we recommend the use of a non chlorine dased disinfectant such as Fernox LP Sterox as manufactured by C ookson Electronics when carrying out disinfection of systems incorporating these appliances.

Remove the ﬁ lter from the combination inlet group clean and replace. Reﬁ 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. T he Pressure Relief Valve should not operate during the heating cycle.

The boiler/heating systems should be filled and commissioned in accordance with good practice following the guidance in BS 5449/the boiler manufacturers instructions. This includes adequately ﬂ ushing the system to remove any debris that may have been introduced during installation/maintenance.

NOTE: This appliance is co vered by BENCHMARK and the log book must be completed after commissioning and after every maintenance/ service visit.

IMPORTANT - DRAIN DOWN PROCEDURE

1 Switch off both the boiler and the immersion heater

2 Open the nearest hot tap and run all hot water until cold

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

5 Open all the taps in the property

6 Open the drain cock and immediately hold open the pressure and

temperature relief valve again until the cylinder is empty

Page 20

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

The temperature of the hot water is adjustable, but the control thermostat should have been set to 60˚C to meet the relevant regulations/ensure safe oper ation. In the direct pattern, the contr ol thermostat is part of the immersion heater and should only be adjusted by a suitably competent tradesperson. A simple, manually adjustable control thermostat is ﬁ tted to the indirect pattern units, but it is recommended that this is left at 60˚C as hotter water will increase the risk of scalding.

When initially opening the taps, a small surge in ﬂ 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 ﬂ 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 off, but do not turn off the cold water to the appliance until the dischar ge 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 r egistered installer / a suitably qualiﬁ 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 o verheat thermostats/

wiring.

USER INSTRUCTIONS

Page 21

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 wat er supply contains a high proportion of solids, eg, sand. Maintenance must include the following:

1. Check and clean ﬁ 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 fr om temperature and expansion relief valv es are free from obstruction and blockage and are not passing any water.

5. Check the condition and if necessary descale the heat exchangers in hard water areas.

6. Check that water pressure downstream of pressure reducing valve is within the manufacturers limits.

7. Check operation of motorised valve.

8. Check the pressure on the air side of the expansion vessel. This must be done when the volume in the cylinders is cold.

9. Check and advise the householder not to place any clothing or other combustible materials against or on top of this appliance.

10. On completion of the work, ﬁ ll in the Service Record part of the Benchmark Log Book.

SERVICING AND MAINTENANCE

IMPORTANT NOTE

When draining down the appliance for any reason, the instructions provided in the Commissioning Section MUST be followed to prevent potential damage to the cylinder.

SERVICING AND MAINTENANCE

FAULT FINDING

Scale

In hard water areas it is recommended that an in-line scale inhibitor is ﬁ tted. Reducing the temperature of the stored water will reduce the rate at which scale forms. If the recovery rate is badly affected, this is an indication that scaling may have occurr ed. 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 ﬁ tted so that water is ﬂ 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 ﬁ 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 wat er pressure is too high, this would suggest that the Pr essure Reducing Valve is at fault and the Gledhill approved replacement should be ﬁ 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 off the heat source, but not the water supply.

When the supply is cool, check thermostats and energy cut-outs in the boiler and immersion heaters and replace the faulty component with a unit supplied by Gledhill and check that it works correctly before returning the system to full operation.

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

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

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

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 appliance within each product range manufactured by Gledhill.

The maximum weight of thelargest product in any range can be up to98kg and the size is 595 x 595 x 2020 mm high.

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)

ControlMeasures

Manual lifting procedure

The lift, key factors in safe lifting are:

a. Balance b. Positionof back c. Positioning of the arms and body d. Thehold e. Takingthe 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. 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 topof the appliance to ensure easy lifting at the top of the product. Each appliance is supplied with a pallet, which has been attached to the unit via the packaging. The pallet will also allow for one or two persons to get 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 andin 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. The unit handles and packaging with the pallet have been designed to ensure that two-four people can assist when lifting up stairs or over longer distance.

Individual capability

Individual capability plays an important part in handling these products. Persons above average build and strength will ﬁnd it easier and should be in good health. Persons below average build and strength may require more rest periods during the handling process. Pregnant women should not carry out this operation. Persons who are not in good health should seek medical advice prior to commencing any lifting or manual handling operation.

Residual risk

Following the guidelines givenabove will reduce any risk to injury. 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.
