General Information
This product complies with the BS EN 1111:1999 (HP) thermostatic mixing valve standards and
satisfies the requirements of the Water Supply (Water Fittings) Regulations 1999 and current
bylaws.
Designed to be used within systems designed to BS 6700.
BS 6700 recommends the temperature of stored water should never exceed 65ºC. A stored water
temperature of 60ºC is considered sufficient to meet all normal requirements and will minimise
the build up of lime scale in hard water areas (see Map of Hard Water Regions in the UK on page
24).
If the shower valve is installed at low pressure (tank fed), then the minimum distance from the
highest installed position of the showerhead to the underside of the cold tank should be at least
2 metres to ensure adequate performance.
These shower valves should be installed in compliance with the Water Regulations. For further
details contact you Local Water Authority.

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.
If all these conditions are met, proceed to set
the temperature as stipulated in the
setting section.
The mixed water temperature at the
terminal fitting must never exceed 46ºC.
When commissioning / testing is due the
following performance checks shall be carried
out:
•
Measure the mixed water temperature at
the outlet.
•
Carry out the cold water supply isolation
test by isolating the cold water supply to
the TMV, wait for five seconds, if the water
is still flowing check that the temperature
is below 46ºC.
22
If there is no significant change to the set
outlet temperature (+/-2ºC or less change
from the original setting) and the fail –safe
shut off is functioning, then the valve is
working correctly and no further service work
is required.
Notes: If there is a residual flow during the
commissioning or the annual verification (cold
water supply isolation test), then this is
acceptable providing the temperature of the
water seeping from the valve is no more than
2ºC above the designated maximum mixed
water outlet temperature setting of the valve.
Temperature readings should be taken at the
normal flow rate after allowing for the system
to stabilise.
The sensing part of the thermometer probe
must be fully submerged in the water that is to
be tested.
Any TMV that has been adjusted or serviced
must be re-commissioned and re-tested in
accordance with the instructions in the setting
section.
The installation of thermostatic mixing valves
must comply with the requirements of the
Water Supply (Water Fittings) Regulations
1999.
Maintenance
General Cleaning
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
valve 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 non –
scratch cleaners.
4. Push the handle back onto the valve spindle
and replace the handle, screw and handle
cover cap.
Cartridge Maintenance
We advise that the shower valve is regularly
serviced in hard water areas to maintain
optimum performance (see Map of Hard Water
Regions in the UK overleaf).
Note: Never use abrasive detergents or
disinfectants or those containing alcohol,
hydrochloric acid or phosphoric acid.
Isolate both hot and cold water supplies to the
mixer valve by either:
Bristan recommend E-cloth for
cleaning all of our bathroom &
kitchen products. Using just
water , E-cloth gives a smear
free, deep clean by breaking up
and holding dirt, which normal cloths leave
behind. Order through your Bristan stockist
(order code: ECLOTH).

Flow Valve Maintenance
• Turning off the isolation valves to the mixer
valve.
1. Remove the temperature control cover cap,
loosen the screw and pull the handle off the
cartridge spindle
If your shower valve begins to drip it may be
due to the flow valve letting water pass
through the valve.
2. Remove the plastic stop. Important:
Take note of the position of the plastic stop and
handle – they must be refitted in the same
positions.
Isolate both hot and cold water supplies to the
mixer valve by either:
3. Unscrew the thermostatic cartridge from
the body.
• Turning the water supply off at the mains
stopcock or
• Turning off the isolation valves to the mixer
valve.
1. Remove the flow control cover cap,
loosen the screw and pull the handle off the
valve spindle.
2. Using a suitable spanner unscrew the
valve out from the body and check its
condition.
3. Clean the valve and replace if necessary.
4. Place the cartridge in a bowl and carefully
add hot water (just off the boil) and vinegar to
de-scale the cartridge. Leave in the solution
until the water has cooled and rinse with clean
water.
5. Grease the seals with a silicon grease
supplied by Bristan (part number: SP-4950002) and carefully refit.
6. Reset the maximum temperature and refit
the handle, screw and handle cover cap.
