Important Safety Information
•Please read these instructions thoroughly and retain for future use.
•All products manufactured and supplied by Bristan are safe provided they are installed,
used correctly and receive regular maintenance in accordance with these instructions.
• If you are in any doubt about your ability to install this shower valve safely you must
employ the services of an experienced qualified plumber.
•These fittings need to be installed in accordance with, and meet the requirements of
the Water Supply (Water Fittings) Regulations 1999 and Scottish Byelaws 2004.
•Warning: Do not operate the shower valve if you suspect it is frozen. Do not site
the shower valve where it might be subjected to freezing conditions.
•Do not crush or kink the shower hose, this could damage the hose and cause leaks.
•Remove all packaging and check the contents for damage before starting installation.
•Before starting any installation please consider the following: before drilling into walls,
check that there are no hidden electrical wires, cables or water supply pipes. This can
be checked with the aid of an electronic detector.
•If power tools are used do not forget to: - Wear eye protection
- Unplug equipment after use
•Fitting isolating valves to the inlet feeds is required for ease of maintenance.
•Warning: Before installing the new shower valve it is essential that you thoroughly
flush through the pipework in order to remove any remaining swarf, solder, etc.
Failure to carry out this procedure could cause problems or damage to the workings of
the shower valve.
• It is recommended that when installing the valve in a recessed situation, full access
is provided for servicing purposes.
•This shower valve must not be modified in any way as this will invalidate the
guarantee.

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 28).
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 1 metre 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.

Installation Requirements
This shower valve must be installed
in compliance with current water
regulations. If you have any doubts about
the water regulation requirements contact
your local water services provider or use
the services of a professional plumber.
This shower valve is suitable for use with
the following water supply systems:
• Gravity Fed Hot and Cold
(pressure balanced)
• Gravity Fed Hot and Mains Cold
(differential pressure - see Specification
section on page 13)
• Instantaneous water heater
(combination boiler)
• Unvented System
• Pumped System
Gravity Fed Hot and Cold Gravity Fed Hot and Mains Cold
cold mains supply cold mains supply
Important: If you install this shower
valve with a gravity fed system, there must
be a minimum head (vertical distance)
from the underside of the cold water
storage tank to the showerhead position
of at least 1 metre.
Note: Pumped system (with Essex
flange) If you install this shower valve to
a pumped gravity fed system where the
minimum head (vertical distance) from
the underside of the cold water storage
tank to the top of the hot water cylinder
is less than 1 metre we recommend an
Essex flange is used as shown.
Flushing Pipe-work
Important: Before connecting the
shower valve (see ‘Installation’ on pages
16-23), supply pipe-work must be flushed
to clear debris before connecting the
shower valve. Debris will reduce the
performance and life of the shower.

Installation Requirements
Conditions of use for Type 2 (Thermostatic mixer) valves
High Pressure Low Pressure
Maximum Static Pressure (Bar) 10 10
Flow Pressure, Hot & Cold (Bar) 0.5 to 5 0.1 to 1
Hot Supply Temperature (˚C) 55 to 65 55 to 65
Cold Supply Temperature (˚C) Equal to or Less than 25 Equal to or Less than 25
Note: Valves operating outside these
conditions cannot be guaranteed by the
Scheme to operate as Type 2 valves.
If a water supply is fed by gravity then
the supply pressure should be verified
to ensure the conditions of use are
appropriate for the valve.
Recommended outlet
temperatures
The BuildCert TMV scheme recommends
the following set maximum mixed
water outlet temperatures for use in all
premises:
44˚C for bath fill but see notes below;
41˚C for showers;
41˚C for washbasins;
38˚C for bidets.
The mixed water temperatures must
never exceed 46˚C.
The maximum mixed water temperature
can be 2˚C above the recommended
maximum set outlet temperatures.
Note: 46˚C is the maximum mixed water
temperature from the bath tap. The
maximum temperature takes account of
the allowable temperature tolerances
inherent in thermostatic mixing valves and
temperature losses in metal baths.
Warning: It is not a safe bathing
temperature for adults or children.
The British Burns Association
recommends 37 to 37.5˚C as a
comfortable bathing temperature for
children. In premises covered by the Care
Standards Act 2000, the maximum mixed
water outlet temperature is 43˚C.
The thermostatic mixing valve (TMV)
will be installed in such a position that
maintenance of the TMV and its valves and
the commissioning and testing of the TMV
can be undertaken.
The fitting of isolation valves is required
as close as is practical to the water supply
inlets of the thermostatic mixing valve.

Selecting Flow Regulators
Regulators can be fitted if water economy is required.
Yellow (5 litre) regulator may not be necessary on some gas water heaters.
Important: It is a requirement of Instantaneous Electric Heaters that a stable
flow of water passes through the heater. This requirement can be satisfied by
using a ‘flow stabiliser’ fitted prior to the heater and should be adjusted to give a
temperature of between 45 - 50˚C from the heater.

Flow Regulators etc.
Flow regulators are factory fitted.
Study the table on the previous page and
decide which flow regulators etc. are
required for your particular situation.
Unscrew both inlet elbows from the valve
body and both compression nuts from the
elbows.
Insert filters (4), washers (5), required
flow regulators / white disc (7, 8 or 9) and
retaining rings (6).
Reattach the compression nuts (ensuring
the olives are in place) and screw the inlet
elbows back into the valve body.
