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.,
