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 product 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.
•Remove all packaging and check the fitting for damage before starting installation.
•Warning: 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
•Important: Remember to turn off the mains water supply before connecting to any
existing pipe work. Fitting isolating valves to the inlet feeds is recommended for ease
of maintenance.
•Warning: Before installing the new fitting 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 fitting.
•Take care when handling the ‘flexible connecting pipes’, do not bend, twist or crush
them. Only tighten the pipes by hand.
•Do not crush or kink the shower hose, this could damage the hose and cause leaks.
•Do not operate the shower attachment if the showerhead or shower hose has been
damaged or is blocked.
•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 fitting 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.
Note: Never use abrasive detergents or disinfectants or those containing alcohol,
hydrochloric acid or phosphoric acid.

General Specifications
Operating pressure range: Minimum 0.2 bar, Maximum 5.0 bar.
Maximum static pressure: 10.0 bar.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance with mixer taps.
Designed to comply with BS EN 200 for single taps / combination taps and BS EN 817 for
single lever mixers, for water systems of type 1 and 2 general technical specifications
and to be used within systems designed to BS 6700.
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.
If the fitting is installed at low pressure (tank fed), then the minimum distance from the
highest installed position of the outlet to the underside of the cold tank should be at
least 2 metres to ensure adequate performance.
These taps and mixers should be installed in compliance with the Water Regulations.
Where the supplies are unbalanced, i.e. Hot water from cylinder tank / cold from the
mains, approved check valves must be fitted in the supply pipes.
For further details contact your Local Water Authority.
Important: To ensure the tap/mixer fittings are securely fastened to the basin/bath
we recommend the relevant torque setting (table shown below) is applied to the ‘Push-
fit connector’ when tightening to the back nuts.

Installation Requirements
These fittings need to be installed in accordance with the following Installation
Requirements and Notes (IRN) to ensure they meet the requirements of the Water Supply
(Water Fittings) Regulations 1999 and the Scottish Byelaws 2004.
IRN R001 (1/2” Basin Taps, 3/4” Bath Taps, Basin Mixer, Bath Filler, Bath Shower Mixer)
See text of entry for Installation Requirements or Notes.
IRN R006 (1/2” Basin Taps, 3/4” Bath Taps, Basin Mixer, Bath Filler)
This tap or combination tap assembly has a Type AUK3 air gap and is therefore for installation
in any premises to protect against a backflow risk up to a Fluid Category 5.
IRN R010 (Basin Mixer, Bath Filler, Bath Shower Mixer)
Water supplies shall be reasonably balanced pressures from a common source (e.g. hot
and cold supplies both from the same storage or both from a supply pipe). Where the fitting
is supplied from unbalanced supplies (e.g. hot and cold supplies from separate sources) a
‘Listed’ single check valve or some other no less effective backflow prevention device shall
be fitted immediately upstream of both hot and cold water inlets.
IRN R040 (Bath Shower Mixer)
The fitting shall be installed so that its outlet discharges above the spill-over level of any fixed
appliance as indicated below:-
For backflow protection in domestic or installations up to, and including, Fluid Category 3.
1. Size of tap or combination fitting. 2. Vertical distance of outlet above
spill-over level.
1. Not exceeding 1/2 in 20mm
2. Exceeding 1/2 in but not exceeding 3/4 in 25mm
3. Exceeding 3/4 in 70mm
If the fitting cannot be installed as indicated in the table it shall be installed:
a) with an approved double check valve assembly or some other no less effective
backflow prevention device immediately upstream of the inlet; or
b) so that it draws water by gravity only from a cistern, or cylinder having a permanently
open vent pipe, and the distributing pipe supplies no other fitting (other than draining
tap) at a lower level.
For backflow protection in premises or installations up to, and including Fluid Category 5.
The vertical distance of the outlet above the spill-over level shall be no less than 20mm or
twice the diameter of the inlet pipe to the fitting, which ever is the greater. If the fitting cannot
be installed as indicated it shall be installed with a backflow prevention arrangement suitable
for the Fluid Category.

Installation Requirements
Flexible Connecting Pipes
Care must be taken when connecting the
flexible connection pipes to the household
pipework to ensure they do not bend sharply
and kink or twist.
The Integral Isolation Valves
The integral isolation valves must be
accessible with a suitable flatblade
screwdriver for turning on and for future
servicing purposes.
See below for recommended ways to fit the
flexible connecting pipes.
See below for the off and on positions of the
isolation valves.
