General Information
Operating pressure range: Minimum 0.1 bar, Maximum 5.0 bar.
Maximum static pressure: 10.0 bar.
This product has been tested to the TMV2 scheme which complies with the BS EN
1287:1999 (LP) and BS 1111:1999 (HP) thermostatic mixing valve standards and satisfies
the requirements of the water supply (water fittings) regulations 1999 and current
bylaws.
BS 6700 recommends the temperature of stored water should never exceed 65°C.
A stored water temperature of 60°C 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 26).
If the fitting 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.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance with mixer showers.
These shower valves should be installed in compliance with the Water Regulations.

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
Maintenance section.
The mixed water temperature at the
terminal fitting must never exceed 46˚C.
It is a requirement that all TMV2 approved
valves shall be verified against the original
set temperature results once a year.
When commissioning / testing is due the
following performance checks shall be
carried out:
If there is no significant change to the set
outlet temperature (+/-2˚C or less change
from the original settings) and the failsafe 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 2˚C 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 Maintenance section.
The installation of thermostatic mixing
valves must comply with the requirements
of the Water Supply (Water Fittings)
Regulations 1999.
• 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 water is
still flowing check that the temperature
is below 46˚C.

Maintenance
General Cleaning
Cartridge Maintenance
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 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 nonscratch cleaners.
We advise that the shower valve is
regularly serviced in hard water areas to
maintain the flow of water (see Map of
Hard Water Regions in the UK on page 26).
Note: Never use abrasive detergents or
disinfectants or those containing alcohol,
hydrochloric acid or phosphoric acid.
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).
Cleaning the Showerhead
Your Bristan showerhead has rub-clean
nozzles for easy cleaning. Simply rub
your fingers across the rubber spray jets
regularly and before you turn the shower
on to remove any scale or debris.
The hardness of the water in your area
will determine how often you should clean
your showerhead. Build up of scale in
particularly hard water areas combined
with constant use means you may need
to clean your showerhead once a week.
To ensure continued performance of
your shower the showerhead needs to be
regularly descaled.
Isolate both hot and cold water supplies to
the shower valve by either:
• Turning the water supply off at the
mains stopcock
• Turning off the isolation valves to the
shower valve
1. Remove the temperature control, undo
the screw, remove the handle and plastic
stop.
Important: Take note of the positions of
the plastic stop and handle - they must be
refitted in the same positions.
2. Unscrew the cartridge anti-clockwise
and remove from the valve body.
3. 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.
4. Grease the seals with a silicon grease
supplied by Bristan (part number:
SP-495-0002) and carefully refit.
5. Reset the maximum temperature and
refit the handle and cover.
