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
THE QUALIFICATIONS
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).

INSTALLATION INSTRUCTIONS
MBSN422D
INSTRUCTION
DIMENSIONS
Please read these instructions carefully and keep in a safe place for further
reference.
General Installation Requirement
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 therefore should be supplied with hot and cold
water at balanced pressures. If the taps are not supplied balanced pressures then
the mixer will not function correctly. It will also be necessary to fit non-return
valves on both the 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
These taps are suitable for high and low pressure installations. They are fitted with
a quarter turn ceramic disc headwork which provides a smooth movement. The
minimum work pressure is 0.2bar. The maximum work pressure is 5bar. If the mains
pressure is over 5bar, a pressure reducing valve should be fitted.

Approvals
All taps are manufactured using materials tested and approved under the Water
Bylaws Scheme and comply with requirements of European standard EN200 where
applicable.

Preparations and bylaw requirements
These taps are single flow so the hot and cold water mix in the body. Water Bylaws
require that where hot water is supplied from tank and cold from 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 are prepared in your guidance; you must exercise due care at all
times. We do not accept responsibility for any problems that may occur through
incorrect installation .

The chrome plate we use on our taps is very durable, nevertheless care
should be taken when cleaning. It 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 surface to go black or peel.
