INTRODUCTION
Please read these instructions carefully and keep in a safe place for future reference.
General Installation Requirements.
The installation must comply with regulations of the Local Water Authority as contained in
their bylaws. All of the taps in this range are single flow and should therefore be supplied
with hot and cold water at balanced pressures, both from the tank or both from the mains
(via a combination boiler for example). If the taps are not supplied at balanced pressures
then the mixer will not function correctly. It will also be necessary to fit non-return valves
on both hot and cold feeds. It is very important that all pipework is flushed thoroughly after
installation to avoid damaging the ceramic discs.
Approvals
All products are manufactured using materials tested and approved under the Water Bylaws
Scheme and comply with requirements of British Standard 5412:1996 where applicable.
Preparation and byelaw requirements
Water byelaws require that where the hot water is supplied from a tank and cold from the
mains, non return valves are fitted on both hot and cold pipes as close as possible to the
tap. These are not supplied. Where combination boilers are fitted it is only necessary to
shut off the incoming mains and turn the boiler off and non return valves are not required.
WARNING
Before installing the new taps it is essential that you thoroughly flush through the
supply pipes in order to remove any remaining swarf, solder or other impurities.
Failure to carry out this simple procedure could cause problems or damage to the
working of the taps.
These hints have been prepared for your guidance, you must exercise due care at all times.
We do not accept responsibility for any problems that may occur through incorrect
installation.
Minimum/Maximum working pressure HP1
These taps are suitable for low and high pressure installations. They are fitted with a half
turn ceramic disc cartridge which provides a good flow rate with very smooth movement.
The maximum water pressure is 6 bar (note: mains cold water is normally supplied at
between 2 and 3bar). For installations where the mains pressure exceeds 6 bar a pressure
reducing valve should be fitted.
