SITING OF THE SHOWER
IMPORTANT:
For ease of servicing, the unit
must always be mounted on the surface of
tiled walls. NEVER tile up to the unit.
Refer to
fig.5
for correct siting of shower.
Position the unit where it will NOT be in direct
contact with water from the sprayhead. Position
the shower unit vertically.

Allow sufficient room between the ceiling and
the shower to access the cover top screws.
Note:
Water Regulations require the sprayhead
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
will in most cases meet this requirement, but if
the sprayhead 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 backflow.
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 sprayhead
which can cause the PRD to operate.
When commissioning, the sprayhead 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.
