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;-
