Fitting InstructionsThermostatic Valve
Please don't remove thispart from the valve unlessyou want to change the pre-set temperature.
The use of check valvesinside the inlets of the shower valve is to stop thedrawback of used or dirtywater into the cold water systems.

Specification
Operating SpecificationHot Water Supply - Max 70˚CRecommended 60-65˚CMaximum temperature pre-set to 43˚C
Operating PressuresMin 0.1 bar - Max 5.0 bar
Always maintain a 10˚C difference between hot system temperature and maximum hotsetting of valve.
Hot and Cold Maximum pressure differential should be no more than 2 bar. If this limit is exceeded, fit a pressure reducing valve (not supplied).
Operating pressures on hot and cold lines should be kept as even as possible in order toensure the maximum effciency of the mixer.When water pressure is higher than 5 bar a pressure reducing valve (not supplied) must befitted before the mixer. Flow restrictors(not supplied) can be fitted into the wall unions to reduce water consumptionon high pressure system.

IMPORTANT:This product is not suitable for instantaneous electrical or gas heater.Rinse the pipework carefully prior to installation of mixer, to remove any debris in the system.Turn off water supply prior to installation1. Prepare the recess in the wall for the mixer body and pipework. See Fig 1 & Fig 2. (see dimension drawing for cavity depth).2. Arrange the pipework so that the hot water is connected from the left and to the inlet marked "H" on the valve body, ensure sufficient pipe length, so that the pipe end insert into the valve a minimum of 10mm. See Fig 1.3. Connect the valve loosely to the pipework, do not tighten.4. Hold the valve in the position inside the cavity and mark the screw holes, disconnect the valve drill the holes and insert wall plugs(12).5. Connect the Thermostatic Valve(10) to the pipework, but do not tighten.6. Tighten Wall screws(11) until secure.7. Tighten connection of valve to the pipework until watertight.8. Turn on the water supply and check for leaks.9. If watertight, remove the handle assembly as below installation. a. Remove the Lever(1) and unscrew the Handle Screw(2). Note: Select A-D models, need to remove the cap first, then unscrew the handle screw(2). b. Remove the Hot & Cold Handle (3) and Regulator handle(4). c. Remove the Flange A(5) and Flange B(7). Note: please don't remove the black stop ring from the Valve Body.10. Push Wall plate(9) over valve body, being sure two holes on the centre of the valve. Refer to Fig 3.11. Screw the Flange A(5) and Flange B(7) to the valve. Make sure that the WasherA(6) and Washer B(8) has been fitted to the Flange A(5) and Flange B(7). Do not over tigthen.12. Re-fit handle assembly as below installation. See Fig 4. a. Refit Hot & Cold Handle(3) to the valve, being sure that the handle stops at the factory pre-set temperature. b. Fit the Regulator Handle(4) to the valve. c. Fit Handle Screw(2) to the handle and tigthen with Allen key. d. Fit Lever(1) to the Handle and tigthen by hand. Note: Select A-D models, need to fit Cap to the handles. Your valve is now ready for use.

AFTER CARETo maintain the appearance of this fitting, ensure it is cleaned using only a clean soft damp
cloth.
A solution of warm water and mild liquid detergent may be used where necessary and then
rinsed thoroughly. Abrasive cleaners or acidic cleaners MUST NOT BE USED under any
circumstances. Avoid contact with solvents.
Please retain these instructions for future reference.
This mixer has been set in the factory under balanced pressures and hot water supply at 65˚C.When your operating conditions vary significantly from the above, the temperature of the mixed water may vary from the setting.In this case, you can set the temperature of the mixer to suit your requirements.The Valve is set to a maximum 43˚C. This can be checked if required using a thermometer. Ifthis temperature is incorrect, you can reset it as the following:
1. Turn the handle to 43˚C position.2. Remove Iever (1), then the Handle Screw(2), then the Hot/Cold Handle(3).3. Without removing the black stop ring and Flange A (5), turn the spindle until the desired temperature is reached.4. When the temperature is reached, re-fit the components so that the Hot/Cold Handle(3) stops at your new set temperature.5. See below Fig 5 for reference.
