INTRODUCTION

This thermostatic valve is suitable for use with all water systems up to a maximum

operating pressure of 5.0 bar, (beyond which we recommend pressure reducing

valves to be fitted).

The thermostatic valve has two outlets that can be controlled simultaneously.

The two main outlets are controlled by the flow control cartridges, commonly used for

a main shower head and a bath spout.

TMV APPROVED INSTALLATIONS

This thermostatic valve has been designed to be compliant with the requirements of

TMV2. NB for installations governed by this legislation the CW marking (as pictured

on valve above) must always be left visible for the commissioning process.

No liability for installation costs will be accepted If, for example, the tiling is too close to

the body of the valve or expanding foam is used preventing the marking of the valve

being visible.Once the inspection has been carried out the cover plate can be fitted.

INSTALLATION INSTALLATION

WS2001RC

NOTES:

Please read these instructions carefully and keep in a safe place for future reference.

The installation must comply with all Local/National Water Supply Authority

Regulations/Bye laws and Building and Plumbing Regulations (UK: BS6700).

This valve is a mixing device and therefore requires the water supplies to be

reasonably balanced, otherwise we recommend a pressure reducing valve to be

fitted.

The valve is fitted with integral WRC approved single check valves cartridges which

command the water supply, therefore the thermostatic valve is protected against

cross-flow due to unbalanced line pressures as required by the Water Supply

(Water Fittings) Regulations 1999.

Fitting isolating valves to the inlet feeds is recommended for ease of maintenance.

INSTALLATION

Remember to turn off the mains water supply before connecting to any

existing pipe work.

Warning! Please check for any hidden pipes and cables before drilling

holes in the wall.

Position the valve onto the wall and mark the position of the fixing lugs (x4). Make

sure the valve is set back from the front face of the wall by the appropriate depth

to allow for plasterboard, filling and tiling etc. (min. 78mm to max. 105mm see

dimension page).

Mount casting to the wall using suitable fixings.

Always leave access to the four front cartridges for servicing.

Once the valve has been secured to the wall, the black Plastic Dust Cover can be

temporally attached to the valve with the screws supplied. This will protect the valve

while the rest of the work is completed (see fig 1).

Inlets and outlets are all tapped BSP. Make all pipe work connections using a

proprietary thread sealer.

Do not use tapered threaded adaptors.

Blank off and seal the open outlet if it is not required.

Remove the Plastic Dust Cover.

Turn on supplies and test all connections for water tightness.

Remove Hot and Cold check valves, and flush out the installation, clean the filters

and refit.

Apply a narrow bead of clear silicone sealant around the back edge of the cover plate

and carefully press into position.

Fit the control knobs by lining up the flat surface of the valve cover with the grub

screw on the handle, tighten the screw with the supplied hexagonal key (see fig 2).

TEMPERATURE SETTING MAINTENANCE

To set the temperature, remove the

handle and unscrew the centre screw of

the thermostatic control cover. Rotate the

exposed thermostatic spindle (clockwise

for cold, and anti-clockwise for hot) until the

maximum desired showering temperature

is set (42 C-suggested maximum pre-set

temperature).

Then line up the screw head on the back of

the thermostatic control cover with the first

stop on the stop ring itself. Push the control

cover onto the splines and tighten the centre

screw, refit the handle. The thermostat is

now set to its new temperature and can only

be increased or decreased by repeating this

process.

MAINTENANCE

Note: To avoid damage, please remove all chrome

parts before any maintenance takes place.

THERMOSTATIC CARTRIDGES

The 1 concealed thermostatic valve should

give trouble free service, but in the event of

failure, servicing is straight forward.

To remove the thermostatic cartridge.

Undo the cartridge clamp nut (take note of

the orientation of the cartridge) and pull the

cartridge out using the temperature control

knob to aid removal. Wash the cartridge with

clean running water and make sure that any

trapped debris has been removed. Dry and

lightly grease the seals (only use silicone

grease) and replace the cartridge making

sure that the locating lug is located in the

recess on the hot side of the valve.

FLOW CONTROL CARTRIDGE

The Flow Control Cartridge uses ceramic discs which normally last indefinitely unless

debris manages to get between them. Wash the cartridge with clean running water, dry and

lightly grease the seal.

FILTERS/CHECK VALVES

The check valves stop cross flow

between the hot and cold supplies.

To clean the Check Valves.

Undo and remove the Check valve.Using

a pair of pliers remove the Non return

valve and filter. Wash the filter with clean

running water, dry and lightly grease the

seals.

CARE OF YOUR SHOWER VALVE

We recommend cleaning the valve with a soft damp cloth.

We strongly advise against the use of ALL cleaning products.

TROUBLE SHOOTING

SYMPTOM SOLUTION

After installation the shower runs HOT

or COLD and will not mix.

Hot and cold supplies are plumbed the

wrong way round.

Remove the thermostatic cartridge,

undo the clamp nut and pull the cartridge

out (using the temperature control knob

to aid removal).

Reinstall it with the locating lug pointing

away from the inlets.

Shower will not run hot enough when

first installed.

Maximum temperature needs adjusting,

see temperature setting .

Cold water tracking through the valve

into the hot water system.

Check and clean the check valve

cartridges and filters located under

the check valves.

Very low flow or no flow (gravity). Check hot and cold feeds (the valve will

shut down if either the hot or cold supply

fails).
