Electric shower
WARNING
The shower
MUST NOT
be
positioned where it will be
subjected to freezing conditions.
IMPORTANT: Water regulations (fig.6)
It is required that the shower head 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’.
If the riser kit is supplied with a ‘soapdish hose
retainer’ or bespoke ‘hose retainer’, it will in
most cases meet this requirement. If the shower
head can still be placed within a bath, basin
or shower tray within the 25mm limit, 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 shower head. This may cause the
PRD to operate.
When commissioning, the shower head must
be removed from the flexible hose. Failure to
follow this procedure may cause the PRD to
operate.
Make sure the shower is positioned over a bath
or shower tray. 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 Experience for
advice on replacing the PRD.
IMPORTANT:
If installing onto a tiled wall,
ALWAYS
mount the unit on the surface of
the tiles.
NEVER
tile up to the unit.
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.
