IMPORTANT:
The unit must be mounted on
a flat surface which covers the full width
and length of the backplate. It is important
that the wall surface is flat otherwise
difficulty may be encountered when fitting
the cover and subsequent operation of the
unit may be impaired.
SITING OF THE SHOWER
IMPORTANT:
If installing onto a tiled wall
always mount the unit on the surface of the
tiles. NEVER tile up to the unit.
Refer to
(fig.6)
for the correct siting of the
shower. Position the unit where it will NOT
be in
direct contact with water from the showerhead.
Position the shower unit vertically.
Allow enough room between the ceiling and the
shower to access the cover top screws. Leave
enough space between the right-hand side of the
unit and the wall to allow access to the pressure
relief device (PRD) in the future.
Note:
Water regulations require the showerhead
be ‘constrained by a fixed or sliding attachment
so that it can only discharge water at a point not
less than 25mm above the spill-over level of the
relevant bath, shower tray or other fixed appliance’.
The use of the gel hanger/hose guide (if supplied)
will in most cases meet this requirement, but if the
showerhead can be placed within a bath, basin or
shower tray, then a double check valve, or similar,
MUST
be fitted in the supply pipework to prevent
back-flow.
Pressure relief device - PRD
A pressure relief device (PRD) is designed into
the shower unit which complies with European
standards. The PRD provides a level of appliance
protection should an excessive build up of pres-
sure occur within the shower.
Do not operate the shower with a damaged or
kinked shower hose, or a blocked showerhead
which can cause the PRD to operate.
When commissioning, the showerhead must
be removed from the flexible hose, while at the
same time the temperature control must be at
the minimum flow position. Failure to follow this
procedure may also cause the PRD to operate.
Make sure the shower is positioned over a bath
or shower tray because if the PRD operates, then
water will eject from the bottom of the unit.
Should this happen, turn off the electricity and
water supplies to the shower at the isolating
switch and stopvalve. Contact Customer Service
for advice on replacing the PRD.
