5.35 Ensure that all three screws hold the
shower backplate to the wall firmly.
5.36 Strip the outer insulation sheath back
as required.
5.37 Strip the insulation from the cores and
make connections to the LIVE (L) (brown
or red), NEUTRAL (N) (blue or black) and
EARTH
terminal block. The earth wire
must be sleeved green/yellow. Make sure
that the cores of the cable lie tidily and do
not touch any metallic part of the shower.
They must not be under strain. There is
no cable clamp.
5.38 Ensure that the cable does not foul
the area above the bottom removable
section, where the knob gear will fit when
the front cover is fitted into place.
5.39 Make sure that all the terminal block
screws are tightened very firmly. Replace
the bottom section of the backplate.
FITTING THE FRONT COVER
5.40 Turn the valve fully clockwise (open).
Turn the water control knob in the cover
so that the pointer is at the 7 o'clock
position.
5.41 Carefully fit the cover to the
backplate, ensuring that the lugs slide into
their sockets. You may have to adjust the
water control knob slightly to enable its
gear to mesh with that of the control valve.
NOTE: The alignment post on the
underside of the cover fits into the recess
in the centre of the valve gear to aid the
fitting of the cover.
5.42 Fit the cover fixing screws. The
longer one is for the lower fixing point. You
may have to push the front cover firmly
against the backplate seal, to enable the
screws to locate properly.
COMMISSIONING
NOTE: The first commissioning of the
shower is intended to ensure the heater
unit contains water before the unit is
switched to the high setting.
5.43 Secure the handset on the riser rail
where it can spray safely. Turn on the
water isolating valve (if applicable).
5.44 Turn the water control knob fully
anticlockwise, then half a turn clockwise.
5.45 Turn on the electrical isolating switch.
Press the 'LOW' button and check that the
'LOW' light comes ON. There may be
gurgling noises as the water fills the heater
can.
NOTE: The shower can be turned on by
pressing either the 'START/STOP', (in this
case it turns on at the power setting last
used) or by pressing one of the power
selector buttons.
5.46 Allow water to flow for about 30
seconds, press the 'HIGH' button, check
the 'HIGH' light comes ON and the 'LOW'
light goes OFF. Turn the water control
knob clockwise until the lower three lights
of the temperature display are ON. Turn
clockwise for warmer and anticlockwise
for cooler. Allow a few seconds after each
adjustment for the temperature to
stabilise.
5.47 The more indicators ON in the
temperature display, the higher the spray
temperature will be. Continue to turn the
water control knob clockwise; the flow will
reduce and the 'LOW FLOW' light will
flash. Turn the water control knob
anticlockwise until the 'LOW FLOW' light
goes OFF and the temperature display is
lit as previously.
NOTE: Should the 'USER PROTECT'
light flash, refer to the User Protect System
section.

PREPARATION
5.1 Remove the three fixing screws
which hold the front cover onto the
backplate. Note that the lower screw is
longer than the upper two.
5.2 Carefully remove the cover which
holds the control knob by pulling directly
away from the backplate.
Bottom
section
Figure 8 Removing cover
5.3 Carefully take out the removable
bottom section of the backplate by lifting
its sockets clear of the pegs on the
backplate. This allows greater access for
installing the cable and pipe. Keep it safe,
as it could easily be damaged.
5.4 Decide which entry points you will use
for cable and water pipe - see Fig. 9.
5.5 Decide where to mount the shower,
refer to Section Three for guidance.
Ensure that you leave enough room
around the shower for removal of the front
cover for inspection or servicing at a later
date.
5.6 It is best to mount the shower on top
of any tiling, so that it can be replaced
easily in the future without requiring
re-tiling. If you must tile around the
shower, DO NOT grout right up to the
shower backplate as this makes
subsequent removal difficult. Do not seal
the shower to the wall using bath sealant,
as the shower will not be harmed by water
dripping behind it.
5.7 Remove the relevant areas of the
backplate, which are not knockouts, using
a sharp knife and/or a round file.
WARNING
5.8 The printed circuit board (pcb) is quite
fragile and very expensive. It is positioned
fairly close to the top right-hand mounting
hole of the backplate; if you are in danger
of damaging a board during mounting the
shower, it can be removed temporarily by
carefully pulling it from its four mounting
pegs. The long narrow section of the
board on the left is weak, so ensure that it
is not put under any stress. The board
will still remain attached by its leads and
should not be disconnected; position it
carefully while you fix the shower to the
wall.
5.9 When repositioning the pcb, ensure
that it fits into place without fouling
anything, with its holes over the mounting
pegs. Then push the board firmly near
the four pegs so that it snaps into place.
CABLE ENTRY
5.10 Available entry points:- top, bottom
and rear (rear is generally the easiest).
Side entry is not possible. The thinned
areas in the backplate and bottom section
are suitable for a cable size up to 16mm².
5.11 For rear entry, cable must emerge
from the wall only in the areas specified in
Fig. 9. You will need at least 280mm of
cable to emerge from the wall to allow
connection to the terminal block.
