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 correct siting of shower.
Position the unit where it will NOT be in direct
contact with water from the showerhead.
Position the shower unit vertically.
Leave enough room between the ceiling and the
shower to allow access to the cover top screws.
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 supplied retaining
ring/gel hanger 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 safety device
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
pressure 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.
