When in medium (eco ) setting the button must be pressed to increase the water flow. 2 2. Temperature Control Adjustable temperature control. Only press the button (and turn the control) when a water temperature over 38˚ is required.
Installation Requirements This shower valve must be installed in compliance with current water regulations. If you have any doubts about the water regulation requirements contact your local water services provider or use the services of a professional plumber. Important: If you install this shower valve with a gravity fed system, there must be a minimum head (vertical distance) from the underside of the cold water storage tank to the showerhead position of at least 1 metre.
Installation Requirements Instantaneous Water Heater Unvented System cold mains supply Pumped System cold mains supply Pumped System (with Essex flange) 1m min. 1m min. If less than 1m see note.
Installation Requirements Conditions of use for Type 2 (Thermostatic mixer) valves High Pressure Low Pressure 10 10 Maximum Static Pressure (Bar) Flow Pressure, Hot & Cold (Bar) 0.5 to 5 0.1 to 1 Hot Supply Temperature (˚C) 55 to 65 55 to 65 Cold Supply Temperature (˚C) Equal to or Less than 25 Equal to or Less than 25 Note: Valves operating outside these conditions cannot be guaranteed by the Scheme to operate as Type 2 valves.
Installation Requirements Flow Regulators This shower valve is supplied with a 7 litre per minute flow regulator fitted in each water inlet which must be left in place when installed in conjunction with an instantaneous water heater/combination boiler. Fitting both flow regulators and turning the water heater/combination boiler to its hottest setting, will ensure a sufficiently hot water supply to the shower valve during winter months (in the UK), when the mains cold water supply is at its coldest.
Installation Requirements This fitting needs to be installed in accordance with the following Installation Requirements and Notes (IRN) to ensure they meet the requirements of the Water Supply (Water Fittings) Regulations 1999 and the Scottish Byelaws 2004. IRN R001: See text of entry for Installation Requirements or Notes.

Installation - First Fix Before Installation Flush through the pipework to ensure removal of debris. Turn off the mains water supply and close any isolating valves. 1. Prepare water supply pipes The centres of the hot and cold water supply pipes should be 150mm apart. At least 30mm of the 15mm diameter supply pipes should protrude through the finished wall surface. Important: Water supplies to the mixer must be with hot on the left and cold on the right when viewed from the front. 2.
Installation - Second Fix 1. Fit covers Screw the covers (5) over the wall plates/ fixing bridges (4), so they are flush against the wall. 4 5 4 5 2. Attach shower valve Place the filter washers (6) into the shower valve fixing nuts. Position the shower valve (1) against the fixing bridges and carefully tighten the shower valve fixing nuts onto the fixing bridges. Do not overtighten. Note: Take care not to damage the finish of the shower valve fixing nuts.
Installation - Riser Rail 1. Mark the position Position the assembled riser rail on the wall, bearing in mind the different heights of people likely to use the shower and the length of the hose when connected to the shower. Note: If replacing an existing riser rail, check to see if the existing holes can be reused or covered by the new wall brackets. Try to avoid drilling close to the edge of tiles, drill in the middle of the tiles or in the tile joints.
Installation - Riser Rail cont. 3.Insert rail clamps Insert the rail clamps into both wall brackets. 4. Insert riser rail Push the riser rail up through the bottom wall bracket. Push the slider down onto the riser, ensuring it is the correct way up - as shown. Then push the riser rail up through the top wall bracket. Rail clamp Bottom wall bracket 5. Tighten rail clamps Centre the riser rail within the wall brackets and tighten both clamps onto the rail. 6.
Installation - Riser Rail cont. Attaching the Shower hose 7. Connect shower hose to shower valve Screw the shower hose (ribbed nut end) onto the mixer ensuring that the rubber washer is fitted. 8. Connect shower hose to showerhead Screw the shower hose (conical end) onto the showerhead ensuring that the rubber washer is fitted. Place the showerhead into the slider.
Operation Water Flow Control (1) Water flow settings: Off ( ), Medium (eco ) and High ( ). Controls the amount or flow of water from the showerhead. 1 When in medium (eco ) setting the button must be pressed to change the setting. 2 Temperature Control (2) Adjustable temperature control. Only press the button (and turn the control) when a water temperature over 38˚ is required.
Commissioning Commissioning notes for Thermostatic Mixing Valves The first step in commissioning a thermostatic mixing valve is to check the following: 1. The designation of the thermostatic mixing valve matches the application. 2. The supply pressures are within the valves operating range. 3. The supply temperatures are within the valves operating range. 4. Isolating valves (and strainers preferred) are provided.
Maintenance General Cleaning Cartridge Maintenance Your fitting has a high quality finish and should be treated with care to preserve the visible surfaces. All surfaces will wear if not cleaned correctly, the only safe way to clean your mixer is to wipe with a soft damp cloth. Stains can be removed using washing up liquid. All bath cleaning powders and liquids will damage the surface of your fitting, even the nonscratch cleaners.
Maintenance - cont. Adjusting the Temperature The shower valve has been factory set with equal (balanced) hot and cold water supply pressures with the hot water supply at 65˚C. If your operating conditions are different from those above, the outlet water temperature may differ from the factory setting. If required the shower valve can be recalibrated to suit your own temperature requirements. Set the temperature control to 38˚C and check the temperature of the water with a thermometer.

Troubleshooting Symptom Cause Remedy No flow or low flow rate and / or varying temperatures. Check showerhead, hose and filters for any blockage. Clean as necessary, refer to Maintenance section (page 23). Partially closed stop or service valve in water supply pipework to the shower valve. Open stop or service valve. Instantaneous water heater cycles on and off as the flow rate or pressure is too low. Increase water flow rate or pressure through system.
Troubleshooting - cont. Symptom Cause Remedy Maximum water temperature too hot or cold. Maximum water temperature set incorrectly. Reset maximum water temperature. Refer to ‘Maximum Temperature Setting’ in Commissioning section (page 22) and ‘Adjusting the Temperature’ in Maintenance section (page 23). Outlet water temperature too hot / cold. Inlet filter is partially blocked. Check insert filters for any blockages and clean as necessary. Installation conditions outside operating parameters.
