INSTALLATION REQUIREMENTS
Installation must be carried out in accordance with these instructions, and
must be conducted by designated, qualified and competent personnel.
1.
Before connecting the shower fitting the supply pipework
MUST
be flushed to
clear debris.
2. A hose retaining ring is supplied to prevent the handset from dropping below
the spill-over level of the bath or shower, which could lead to contamination from
back-siphonage. For category 5 installations, the category 5 fittings set
MUST
be used.
3.
Installations
MUST
comply with all the Local and National Water Supply Authority
Regulations and Byelaws (Scotland), Building and Plumbing Regulations in force
at the time of installation. The installation should be carried out by a plumber or
contractor who is registered, or is a member of, an association such as:
- Institute of Plumbing (IOP), throughout the UK.
- National Association of Plumbing, Heating and Mechanical Services
Contractors (NAPH & MSC), England and Wales.
-
Scottish and Northern Ireland Plumbing Employers’ Federation (SNIPEF),
Scotland and Northern Ireland.
4. When installing the shower fittings in a cubicle, it is best positioned to spray
across rather than towards the opening of the cubicle.
5.
Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
6. Do not use excessive force when making connections.
7. Do not
install the shower fitting in a position where it could become frozen.
8. Do not
fit any form of flow control in the outlet pipework if the shower fitting is
installed in conjunction with a product that requires the fitting to act as a vent
(e.g. an electric shower).
9 . Layout and sizing of pipework should be such that when other services are
used, pressures do not fall below the recommended minimum for the shower
fitting as this will cause the spray pattern to collapse.
10.
For a gravity fed shower installation, the minimum pressure at the shower fitting
is 0.06 bar. To generate the minimum pressure and accommodate the pressure
loss in the pipes and shower control, a head of water of 1.5 metre is required
on a typical correct installation.
11. The shower fitting is connected to the bottom outlet of the shower control or
shower outlet of the bath shower mixer as appropriate.
