This product should only be fitted by a qualified plumber to NVQ (National Vocational
Qualification) or SNVQ (Scottish National Vocational Qualification) Level 3. Should
the installation be completed by a non-qualified person then the guarantee may be
considered invalid.
For a claim made under our warranty written certification of your installers credentials
can be required. For further information or to find a qualified installer in your area
please visit the Institute of Plumbers website - www.iphe.org.uk
At present, to be a plumber you need to follow the National Vocational Qualification
(NVQ) route (Scottish National Vocational Qualification - SNVQ - in Scotland). These
qualifications are made up of theory and practical work in the classroom/purpose built
training facility and work based experience with a working plumber. Colleges should
help students find a work placement, although many students organise it themselves.
The S/NVQ qualification works in levels. All recently qualified plumbers should hold
S/NVQ Level 2 as basic with Level 3 as the preferred level. Level 2 will give you the
foundation you need for a career in plumbing and teach you domestic plumbing to a
satisfactory level. Level 3 is more comprehensive and deals with domestic,
commercial and industrial plumbing along with aspects such as gas - if you want to one
day set up your own business, this is the level to reach. The Institute of Plumbing and
Heating Engineering, and the industry as a whole recommends that all plumbers reach
a minimum of Level 3.
Reaching Level 3 has other advantages. The Institute runs a Master Plumber
Certificate, which only those attaining Level 3 or equivalent can reach as long as they
have the relevant experience as well. Those with S/NVQ Level 3 can (once in
membership with the Institute for five years as a Member MIPHE) gain Engineering
Technician EngTech status with the Engineering Council (UK).

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 (the hot and cold water mix in the
body) 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.
Minimum/Maximum working pressure HP1
These taps are suitable for high These taps are suitable for 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.
The tap is fitted with an aerator for use in high pressure installations. If your water is
supplied at low pressure you may prefer to change the nozzle to a flow straightener.
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
These taps are single flow so the hot and cold water mix in the body. 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 mixer 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 mixer.
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.

INSTALLATION INSTALLATION
First shut off your water heating system then, with your mains stop cock closed, open the
lowest hot and cold taps in the house and allow to run until the cold storage tank and pipes
are empty (the hot water storage cylinder always remains full).
Fitting isolating valves to the inlet feeds is recommended for ease of maintenance.
!
The basin spout must be firstly screw the two flexible hoses (as illustrated) into the basin spout
then inserted through the centre tap hole on the basin (or work top) ensuring that there is
enough thread to tighten the spout to the unit .Slide the C- shaped black washer and then the
metal retaining plate up the threaded screw and secure screwing the fixing nut with an
adjustable spanner. Both side bodies must then be fitted (from the under-side of the basin or
work top, without the chrome flanges fitted) making sure that the “back nuts ” are already
screwed onto the threads .The outlets of both side bodies must then be aligned so that the
flexible pipes can supply water to the spout (which have already been secured) .Once this
alignment is achieved the back nuts under the basin can be tightened to allow the chrome
flanges to be fitted from above the controls .The copper pipes then need to be secured using
the compression fittings and washers supplied for the hot and cold supplies.
The Hot (to the left side) and Cold (to the right side) water supplies can then be connected to
the 1/2” fittings at the bottom of each side body.
The tap then must be examined for any leaks under the basin.
INSTALLATION
Remember to turn off the mains water supply before connecting to any existing
pipe work.
ATTENTION
Having first checked all new connections, turn on the mains stop cock, close all taps except the
new mixer and as the system starts to refill check for leaks.
Once you have satisfied yourself that there are no leaks, switch on the water heating.

MAINTENANCE
Once the valve has been set
correctly the collar can be screwed
down to secure the unit. The handle
is then pushed onto the spline and
tightened with the hex key.
CLEANING
The chrome and gold plate we use on our taps is very durable, nevertheless care should
be taken when cleaning them. They should be cleaned only with warm soapy water
followed by rinsing with clean water and drying with a soft cloth. All finishes are vulnerable
to acid attack and some strong substances such as household cleaners, disinfectants,
denture cleaners, hair dyes, wine making and photographic chemicals can cause the
surface to go black or peel.
