Regulations It is important to ensure that the water supplies to your shower are connected in accordance with the water regulations (WRAS) requirements and good plumbing practice. It is Pegler’s recommendation and good plumbing practice that the supplies of hot and cold water to the shower valve should be equal (Balanced) pressure in order to provide a consistent flow. Supplies should be from a common source, either mains or tank fed. If supplies are not equal pressures then a Non Return Valve (801 Non Return Valve) should be fitted. Bylaw 17(2) B The Shower head of any shower hose pipe should be fitted with a fixing or sliding attachment so that it can only be discharges at a point not less that 25mm above the spill over level of the bath tray or fixed appliance Bylaw 30 (2) Where the shower valve is supplied with hot water from a storage cistern and cold water from the mains supply pipe a cold storage cistern that complies to bylaw 30 (2) must be used.

Notes:
1. Check supply parameters are still within the expected values if not check system for faults. 2. Carry out commissioning procedures a to c (see “Commissioning”) using the same test equipment, if the mixed water temperature has changed a significant amount (e.g > 1K ¹ ) check to ensure in lines filters are clean, that the check valves are working and all isolating valves are fully open. If no fault can be found check and record the mixed water temperatures and re-adjust mixed water temperature to the value in the table (see “Mixed Water Temperature”) below. 3. Complete the commissioning procedure a to f (see “Commissioning”) if the mixed water temperature exceeds the values of the maximum recorded temperature by more than 2K the need for servicing work is indicated. Depending on results of these two tests the following should be adopted 1. If a small change (e.g. 1K to 2K) occurs one of these tests or there is no significant change (e.g. 1K maximum) then the next service test should be carried out 24 to 28 weeks after commissioning. 2. If a small change occurs in both tests or a large change occurs in one test (e.g. exceeding 2K) then the next in service test should be carried out 18 to 21 weeks after commissioning. These results can then be used to set a service interval which tests have shown can be used with no more than a small change in mixed water temperature. This method of determining service intervals is used to take into account various in-service conditions (i.e. water condition) that the valve may experience. Mixed Water Temperature After commissioning or any maintenance/servicing its imperative that the water temperatures are check and rest (if applicable) in accordance with the table below. The method of adjustment of temperature is covered in the product specific instructions. Application

The following set of tests should be carried out a) Record the temperature of the hot and cold inlet water supplies b) Record the temperature of the mixed water at the largest draw off flow rate. c) Record the temperature of the mixed water at a smaller draw of flow rate, which shall be measured d) Isolate the cold water supply to the valve body and monitor the mixed water temperature e) Record the maximum temperature achieved as a result of point (d) and the final temperature f) Record the equipment, thermometer etc used for the measurements. ¹) K = Kelvin, the unit of thermodynamic temperature. The unit “kelvin”I s equal to the unit “degree Celsius”. Kelvin is used for a difference of Celsius temperature.
Before installing this product Pegler recommend the reading of this document thoroughly and leaving it with the user for future reference. Introduction It has been recognised that users of hot water in care establishments are at risk from scalding. By using this product Pegler have reduced the risk by designing and using thermostatic mixing valve technology into the body of these products. In order to assure the performance of thermostatic mixing valves the N.H.S. Estate Model Engineering Standard DO8 was written. The products listed below have been tested and approved to this standard by a third party as part of the TMV3 scheme for use within their designated applications. The lists of abbreviations and description below are designated codes used throughout this manual. HP High Pressure LP Low Pressure S Shower Code HP-SE LP-S

Water Regulations Requirements It is important to ensure that the water supplies to your taps and mixers are connected in accordance with the water regulations (WRAS) requirements and good plumbing practice. It is Pegler's recommendation and good plumbing practice that the supplies of hot and cold water to the products should be at equal (balanced) pressures in order to provide a consistent flow. Supplies should be from a common source, either mains or tank fed. If supplies are not equal pressures then non return valves should be fitted (supplied). This products has been designed to function on all types of water systems. Please Note: If a pump is to be installed to boost gravity supplies please refer to the pump manufactures instructions. The hot and cold inlets for any of the products are hot on the left and cold on the right when viewed from the front of the fitting. It is our recommendation and good plumbing practice that a service valve also (Pegler PB300) should be installed upstream in the inlet supply lines. Pipe Connections IMPORTANT. Before making any inlet pipe connections all supplies MUST be thoroughly flushed to remove any debris. Failure to do so could result in damage or low flow from the mixing valve. It is a requirement of the Water Fittings Byelaw Scheme that this function is undertaken before making any pipe connections to supplies. For your shower the connections are 15mm compression with swivel elbows on the exposed model and 15mm compression isolating elbows on the concealed models.
General Installation Notes Care must be taken during installation to prevent any risk of damage to the product or injury to installer. Installation must be carried out by a qualified and competent person and in accordance with the instructions supplied. Installations must comply with all Local and National Water Authority Regulations, and Building/Plumbing Regulations. Please ensure that you have read and understood all sections of this manual before installation. Conditions for normal use In order to comply with the requirements of the N.H.S. Estate Model Engineering Standard DO8 the table below is to be used as conditions for installation. Although in many cases the performance of the product may work suitably outside of these limits the TMV3 approval will not apply. If they are to be required to work outside of these conditions then an approved engineer must carry out a risk assessment and satisfy themselves that the units are still suitable for use. Pegler products have been designed to function under the following conditions: Operating Pressure Range Pressure Drop through Shower for Correct Mixing (bar) Maximum Static Pressure (bar) Flow Pressure – hot and cold sides (bar) Hot Supply Temperature Range (10°C above outlet temperature) Cold Supply Temperature Range (°C)

Cleaning 1. Soak all metal parts in descalent, wash off in clean water. 2. Examine all seals and replace if necessary; maintenance kits are available from Pegler technical. 3. Use silicone based grease on all seal (use a light smear only) and the thread of the spindle and spindle housing. Reassemble 1. Add P.T.F.E washer to spindle from splined end, then 'O' ring. The spindle is then screwed into the spindle housing. 2. Locate the new spindle assembly into the head and fit circlip. Please note: The circlip does not locate on the groove immediately beneath the splines but locates on the next one down towards the threaded end. 3. Take the head assembly and screw onto the half cartridge. 4. Place thermostat into the piston and distributor assembly and place return spring into the recess in the bottom of the piston and distributor (use a dab of grease to retain it in place whilst installing into valve) 5. Offer the piston assembly up to the head assembly ensuring that the thermostat is located in the recess in the adjustment screw. 6. Screw the whole assembly into the valve body and tighten. Please note: Do not adjust the bottom cap unless you are installing a new cartridge. If this is the case screw the bottom cap fully clockwise until it stops, then unscrew anticlockwise ¾ turn only. Then refer to flow regulator table to see if any further adjustment are required for your particular system. 7. Replace sleeve, retaining ring and knob and refer to “Mixed Water Temperature”. 8. After re-setting your desired maximum outlet temperature replace 'O' ring and spindle screw. Finally replace printed indice and carrier.

Recommended Minimum Dynamic Supply Pressure 0.1bar
If the authority concerned does not have a planned test and maintenance schedule then the suggested below should form the basis of a system. At intervals of 6-8 weeks and 12-15 weeks after the commissioning:
Please note: Ensure any temperature gauges are calibrated before use and as much of the temperature probe is located in the flowing water as possible and is done so as close to the outlet as possible. For shower valves this should be done so at the open outlet of the valve and not through hose/handset or shower head.
Please note: For dynamic supply pressure below 0.5 bar Pegler recommends the removal of the flow regulators to allow increased flow. For Shower (894 Exposed Shower - 360051, 894 ISO Shower - 360055 and 895 Concealed Shower - 360052) have a factory preset temperature of 43°C.
6. When the desired temperature is reached retighten screw and push back the indice and carrier.
The temperature differential required between hot supply and outlet temperature is a minimum of 10°C (for example if the required outlet temperature is 43°C then the incoming hot temperature has to be minimum 53°C)
Please note: At no time does the lever handle need to be removed for temperature adjustment. However handle can be removed and relocated if desired. Maintenance If the temperatures of the unit falls out of what are specified for their individual applications then it may be the result of incorrect installation. Please refer to installation and site requirements. If the valve however has operated correctly for some time previous but no longer performs to an acceptable level then it may require servicing/cleaning. Should the valve require servicing then the following procedure should be adopted? 1. Isolate hot and cold supplies 2. Remove the indice in the handle top. This is fixed to the chrome carrier and should be removed as one. 3. Remove the screw from the spindle (water seepage from the spindle is normal) 4. Remove all O rings and save. 5. Remove concealing plate (concealed model only) from around the valve. 6. Remove retaining ring and pull off outer sleeve. 7. Unscrew head using large spanner positioned on hexagonal collar (standard right hand thread applies) 8. Remove the head as an assembly of parts and place aside piston and distributor. DO not dismantle this! Body
Pre-Installation Checks Ensure that there is sufficient space to install the product without hampering its operation. The handle is fixed by a grub screw located under the coloured indice at the front of the handle. Access to this is required for removing handle during maintenance and servicing. The 894 Exposed Shower - 360051, 360055 and 895 Concealed Shower 360052 are supplied with the hot inlet on the left and cold on the right when viewed from the front. The fitting of hot water must be supplied to the correct inlet for these products to work correctly (the hot side is marked “H”). The outlet is facing downwards. Ensure all pipe work has been thoroughly flushed before any installation takes place.

¹ - With certain combi-boilers hot supply and mains cold supply it may be necessary to fit the yellow 5 litre regulator ² - The valve will perform satisfactorily without flow regulators although it is recommended that they are fitted for the purpose of economical water usage ³ - IMPORTANT! It is a requirement of Instantaneous Electric Water Heaters that a suitable flow of water passes through the heater. This requirement can be satisfied by using a flow stabiliser in the supply to the heater. It should be adjusted to give a flow temperature of 45-50ºC from the heater. # - The bottom cap is factory set at ¾ turn from the fully closed position. Only adjust if instructed to do so in the flow regulator table or when fitting a replacement cartridge assembly

Installation Decide on location of pipe installation. Three inlet positions are available for connections of the exposed valve. Top, rear and bottom are available and can be changed by simply rotating the inlet elbow. With the inlet elbows fully screwed tight into the shower body unscrewing the elbows to a maximum one and half turns allows for centre distance adjustment and tolerance. Rotate the elbows to the desired position and check inlet centre distance. Please note: If pipe work is already installed (via retrofit installation) and it is identified the hot and cold supply lines are on opposite sides (hot on right). Then the shower can still be fitted. Unscrew the outlets on the shower body and swap over. This allows the valve to be rotated 180º to suit. It is very important that the inlet marked “H” is always fitted to you hot supply line. On this type of installation you may also need to unscrew handle and relocate. This can be done at your discretion! Installation of 894 Sequential Control Exposed Shower 360051 & 360055 1. Use the exposed chrome backplate from the shower body and use as a template for fixing the holes. (locate and unscrew the grubscrew to remove) 2. Drill and plug the wall to suit screws provided. Fit grubscrews loosely to backplate and secure the plate to the wall. 3. Locate the valve body onto the mounting backplate and fix back in place by locate the grubscrew once more and tighten. 4. Connect inlet pipes to valve with compression fittings. Installation of 895 Sequential Control Concealed Shower 360052 1. It is essential that when fitting a concealed shower (of any kind) that access to the shower valve can be made for service and maintenance purposes. Location nearing an airing cupboard / panel wall or similar are advised as this ensures no disturbance to tiles etc. 2. If location like the above is not possible then a removable access panel of 300mm square minimum fitted to a simple wooden framework could be installed to allow full access and removal of the valve if necessary. A panel of this nature could at least be tiled and held in place with mirror screws.
3. Closely fitted isolating valves (not supplied) are advised when fitting any type of concealed unit. For maintenance and servicing measures required on the valve and the restrictive area they are likely to be mounted in. 4. It's also imperative that the filters provided are used. 5. Once the valve has been installed and tiling around the shower valve complete, both inner and outer seals can be fitted to the oval cover plate. 6. Locate cover plate over lever handle and around the shower valve body and push towards the tiled wall. A bead of clear silicon around the outside of the plate is not required however may be applied if felt necessary to do so. Operating Operation of product is simple and easy. Rotate lever in an anti-clockwise direction and almost immediately you will have full flow. The temperature is controlled progressively warmer as the lever is rotated further. The maximum factory set temperature is 43ºC but may need adjusting due to your specific site requirements. Commissioning Since installed supply conditions may differ from those used in testing and setting the shower valves during final inspection. It is necessary to reset the mix temperature, and then using the following procedure should be used after ensuring: a) The designation of the thermostatic mixing valve matches the intended application (i.e. if the shower valve is supplied at 2 bar then the valve must have HP-S designation) b) The supply pressures match those for which the valve has been approved (see “Conditions for normal use” for valve details) c) The supply temperatures are such that they are within the permitted range (see “Conditions for normal use” for valve details) and comply with the guidance information on the prevention of legionnella. Please note: If the supply conditions are not within the parameters for normal use the valve may still be suitable, but individual engineers must carry out their own risk assessment and satisfy themselves that the units are still suitable. Temperature Setting The maximum blend temperature should be limited to ensure no undesirable temperatures are experienced. If adjustment is required then the following procedures should be adopted. 1. Remove the indice in the handle top. This is fixed to the chrome carrier and should be removed as one, (it is not necessary at this time to remove the lever handle) 2. Turn the lever handle to maximum temperature by rotating ant-clockwise. 3. Remove the screw from the spindle (water seepage from the spindle is normal) 4. Using a small screwdriver with a single blade locate down the spindle of the shower mixer and turn adjusting screw inside. 5. Rotate anti-clockwise for hotter temperature and clockwise for cooler temperature.
