IMPORTANT: Please ensure both supply

pipes are ﬂushed before connecting the

mixing valve to prevent plumbing/pipe

debris from entering the mixing valve.

1. Choose the conﬁguration of the

elbows as per the diagram below.

Choose whether to have a top or

bottom outlet by using the blanking

cap and o-ring.

2. Plumb the pipes to the desired

location for the mixing valve.

3. Remove the backplate and mark the

position of the ﬁxing holes.

4. Drill and use the screws and plugs

provided to secure the backplate to

the wall.

5. Connect the valve to the pipework,

using ﬁlters to prevent debris

entering the valve (not supplied).

We recommend using a high

tightening torque (45-50Nm) on all

22mm compression ﬁttings to

secure the valve.

Remember: Ensure the valve is ﬁtted

with the hot inlet on the left, cold

on the right when viewed from the

front.

6. Locate the valve body on to the

backplate and secure with the

grub screw.

Commissioning

Bristan products are made from

premium materials, with hand polishing

and electroplated ﬁnishes.

Your shower kit should be regularly

cleaned with warm water, a mild

pH-neutral liquid soap, and polished

with a soft cloth. Any residues from

soap, toothpaste, shampoos and

shower gels can cause blemishes if

not rinsed o straight after use.

Household bleaches and cleaners

contain harsh chemicals and may

damage the surface ﬁnish. Avoid using

abrasive cloths, scouring pads, scrub

sponges, steel wool or anything similar.

Working Pressures

The valve is factory set to work at a

high pressure, with the bottom cap

open 3/4 turn. The hot arrow on the

serial sticker will be pointing towards

‘High’ on the sticker on the bottom of

the valve body.

To change to low pressure, turn the

bottom cap 1/4 turn anti-clockwise until

the hot arrow points towards ‘Low’ on

the sticker on the bottom of the valve

body.

Temperature Adjustment

This valve is pre-set to a maximum

outlet temperature of 43°C.

It can be adjusted to have a maximum

temperature between 30°C - 55°C

IMPORTANT: To comply with the

TMV scheme, this valve cannot have a

maximum outlet temperature of 44°C.

If set higher, it will no longer comply

with the TMV scheme.

Please see the TMV manual supplied

with this valve for more details.

To adjust the temperature, follow

the steps below:

1. Turn on the valve and set to the

maximum temperature.

2. Remove the knob insert from

the valve. Using a narrow bladed

screwdriver, insert through the

retaining screw and locate into the

groove of the adjusting screw (Fig 1).

3. Turn the adjusting screw clockwise

for a cooler temperature, anti-

clockwise for a hotter temperature.

4. Wait for a few minutes after adjusting

for the temperature to stabilise. Use

a thermometer to measure the outlet

temperature. Repeat steps X and X

until to reach the desired result.

5. Replace the knob insert.

Temperature Stop Adjustment

This method locks the position of the

control knob so that the valve cannot

reach a higher temperature.

The valve is factory set to the position

below:

• Position the control knob so that the

stops on the inside of the knob are

positioned on each side of the lug in

the sleeve.

• Screw in the retaining screw and

follow the Temperature Adjustment

steps to calibrate the temperature.

• Replace the knob insert.

To limit temperature movement, set to

the position below:

• Position the control knob so that the

stops on the inside of the knob are to

the left of the lug in the sleeve.

• Screw in the retaining screw and

follow the Temperature Adjustment

steps to calibrate the temperature.

• Replace the knob insert.

Maintenance

Servicing the Valve

This valve should at least be serviced

with a frequency as set out in the TMV

manual guidelines to comply with the

scheme. It may need more frequent

servicing if sited in a hard water area to

ensure optimum performance.

Please see the TMV manual supplied

with this valve for more details.

To service the valve, follow

the steps below:

1. Turn both isolating lugs to shut-o

the water supplies. (Fig 3). Remove

the valve from the wall.

2. Remove the ﬁlters from the isolating

lugs and rinse of any debris.

3. Remove the knob insert. Undo and

remove the retaining screw. Remove

the control knob, ring and sleeve to

expose the head assembly.

4. Remove the head assembly from the

body using a 29mm A/F spanner.

Remove the bottom cap and

piston assembly together with the

thermostat and return spring.

Note: The piston can be dis-

assembled further but this is not

necessary for cleaning/servicing.

5. Remove O-rings and check for

damage, replace parts if necessary.

Soak all metal components in a

suitable solution until fully de-scaled.

Grease O-rings using a WRAS

Approved grease.

Re-Assembly

1. Replace piston ensuring ease of

movement when in place. This should

move with light ﬁnger pressure.

2. Replace spring and bottom cap.

Screw in gently, DO NOT use

excessive force.

3. Unscrew the bottom cap by 1 1/4

turns to give correct gap.

4. Re-assemble the head assembly

ensuring the adjusting screw is

screwed back fully.

5. Fit the thermostat into the head

assembly. Fit the head assembly into

the valve body.

6. Re-ﬁt the sleeve and control knob,

secure with the retaining screw.

7. Fit the valve back onto the wall,

ensuring the ﬁlters are in place.

8. Complete the commissioning and

temperature adjustment steps to

re-calibrate the valve.,
