Thank you for choosing Bristan, the UK’s leading taps and showers expert. We have
designed this product with your enjoyment in mind. To ensure that it works to its
full potential, it needs to be fitted correctly. These fitting instructions have been
created to give you all of the information you need and, if you need any further help,
please do not hesitate to give us a call on 0330 026 6273.

Please make sure you read these instructions and retain for future use.
All products manufactured by Bristan are safe, providing they are installed and used
correctly and also receive maintenance when needed.
These fittings, including the connecting water and waste system need to be installed
in accordance with and meet the requirements of the Water Supply Regulations 1999
(Water Fittings) and current by-laws. If you are in doubt about your ability to install
this product correctly or safely, you should employ the services of an experienced
qualified plumber.
This product must not be modified in any way otherwise this will invalidate the
guarantee. Remove all packaging and check the contents for damage before starting
installation.
Warning: Before installing the new mixer 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 mixer valve.
Fitting isolating valves to the inlet feeds is required for ease of maintenance.
Warning: Do not operate the mixer if you suspect it is frozen. Do not site the mixer
valve where it might be subjected to freezing conditions.
Consider the following whilst using power tools:
• Prior to drilling into walls, check there are no hidden electrical cables or
wires and there are also no water pipes. These can potentially be found
using an electrical or metal detector. You may also need to know some
of the schematics of previous installations to determine the suitability
and accommodation of the installation.
• Wear the correct PPE, especially ear, eye and hand protection
when using power tools. Unplug any mains equipment after use.
• Keep electrical equipment away from sources of water.
• If a blow-lamp is used when plumbing, the flame must be kept well away from
the product otherwise damage may occur.
If in doubt, contact a registered plumber, your Local Water Authority or the
Secretary of The Institute of Plumbing, address as follows;-

Important Safety Information

Please refer to your specific shower
contents page for specification
information.
These showers are designed to be used
in conjunction with the kit supplied, or
Bristan shower kits where not supplied.
We cannot guarantee compatability or
adequate performance when used with
other kits. This would also invalidate your
guarantee. Please refer to the installation
manual supplied with your Bristan
shower kits for their specification
information.
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 imbalance should not exceed
a ratio of 5:1 - see Specification section)
• Gravity Fed Hot and Mains Cold
(pressure imbalance should not exceed
a ratio of 5:1 - see Specification section)
• Instantaneous water heater
(combination boiler)
• Unvented System
• Pumped System
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 outlet 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, the supply pipe-work must be
flushed to clear debris before connecting
the shower. Debris will reduce the
performance and life of the mixer.

Installation Requirements

This fitting needs 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: See text of entry for
Installation Requirements or Notes.
IRN R040 - Schedule 2-15 (1): 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.
If the fitting cannot be installed as
indicated in the table opposite it shall be
installed as either a or b below:
a: with an approved double check valve
assembly or some other no less eective
backflow prevention device immediately
upstream of the inlet.
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
fittings (other than a 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 not 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.

Prior to Installation

1. Unscrew both inlet elbows
anti-clockwise from the valve
body.
2. Remove the flow regulators
using long-nosed pliers if required.
3. Screw the inlet elbows
clockwise to fit back into
the valve body.
To Remove/Replace Flow Regulators:
Configuring the Inlet Elbows:
The shower valve is supplied with two
small and two large elbows that can
adjust between 110-155mm.
The elbows can be pointed to feed from
the top, bottom or rear.
Two full turns are required to fit the elbow
into the body properly.
1. Unscrew both inlet elbows
anti-clockwise from the valve body.
2. Choose the elbow configuration
to suit inlet centres:
* 2x small elbows: 110-130mm
* 1x small, 1x large: 130-136mm
* 2x large: 136-155mm
3. Screw in the desired elbows clockwise
for two complete turns to fit. This will
set to largest possible centre
measurement.
4. The elbows can be screwed a maximum
of 1.5 turns after fitting for adjustment.
Screw further clockwise to reduce the
centre measurement; anti-clockwise to
increase.

Prior to Installation

1. Check your shower’s specification
page and check the pack contents
for completeness.
2. Prepare the 15mm water pipework,
leaving sucient pipe protruding
from the finished wall to fit
into the elbows.
Flush through the pipework
to ensure removal of any debris.
Turn o the mains water supply
and close any isolating valves.
Important: Water supplies to the mixer
must be with hot on the left and cold on
the right when viewed from the front.
3. Measure the centre distance.
Measure the half-way point between
the centres and mark on the wall.
4. Configure the inlet elbows to
meet the centre distance.
5. Undo the grub screws at the back of the
shower valve to remove the backplate.
Place the backplate on the marked
half-way point between the centres
and mark the fixing holes
6. Drill the fixing holes using a suitable drill
bit. A pilot drill will be required if drilling
into tiles. Insert the wall plugs and screw
the backplate to the wall.
Warning: Please check for any hidden
pipes and cables before
drilling holes into the wall
7. Fit the nuts and then olives on to the
water supply pipes. Once fitted, feed
the plinths and shower valve on to the
water supply pipes and tighten into
position. Secure the valve to the back
plate using the grub screw.
Please refer to your specific shower
kit instructions, or shower contents
sheet if a kit is supplied to
install the shower kit.
If your shower needs to follow the
TMV scheme, please refer to the
TMV Manual to commission your shower.

Installation

Bristan products are made from
premium materials, with hand polished,
PVD, EPD or electroplated finishes.
Your product should be regularly cleaned
with warm water, a mild pH-neutral
liquid soap, and polished with a
soft cloth. Any residues from soap,
toothpaste, shampoos and shower gels can
cause blemishes if not rinsed
o straight after use.
Household bleaches and cleaners
contain harsh chemicals and may
damage the surface finish. Avoid us-
ing abrasive cloths, scouring pads, scrub
sponges, steel wool or anything similar.
Some surfaces such as nickel and
pewter may be aected by the dye found
in some cloths, so it is also
important to avoid hanging cloths
on surfaces.
