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 tap.
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 for every
0.1 bar of minimum pressure required.
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 page 7), the
supply pipe-work must be flushed to clear
debris before connecting the shower.
Debris will reduce the performance and life
of the bar shower and Wall Mount.

Bristan products are made from premium materials, with hand polished, PVD, EPD or
electroplated finishes.
Your bar shower 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 using 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 fittings/barshowers etc.

Prior to Installation
The installation images are for illustrative purposes only, and your product may
slightly dier in installation, depending on specification. Please refer to your specific
shower kit contents page for specification information.
These kits are designed to be used in conjunction with Bristan showers. We cannot
guarantee compatability or adequate performance when used with other showers.
Please refer to the installation manual supplied with your Bristan shower kits for
their specification information. Your kit could also have adjustability at the wall arm
as a telescopic riser, or come with an in-line diverter kit.
This shower kit 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.
Loosely assemble the riser, making
sure it can reach the connection point
on your fitting and the bracket will
stay flush to the wall.
Plan your installation to accommodate
for the tallest user, and measure
the crucial dimensions for your
installation. Use the diagram
to take notes.
