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.
