Planning the installation
The shower should be located in a position
where walls are protected from water and
sufficient drainage is provided.
1) Consideration should be given to
the location of the nearest cold mains
water supply and the routing of this
to the shower. The shower will accept
a mains supply from the bottom,
back or top of the unit. Remove the
appropriate plastic plate from the
back plate before commencing
installation.
2) Avoid connecting the shower unit
where it will be affected by water
drawn off by other appliances, e.g.
from the mains feed to the W.C. This
may cause a drop in pressure too low
for the shower unit to work correctly.
General
1) Fit an isolating valve to the mains
water supply so that the shower can
be serviced.
2) The shower unit is best placed to the
right hand side of the riser rail and
placed so that the top of the unit sits
alongside the middle to top of the riser
rail. This reduces the amount of water
falling on the unit.
The top of the riser rail should be sited
to coincide with the height of the tallest
person using the shower.
Before drilling any holes check that
there are no hidden cables or pipes
below the surface to be drilled.
To avoid loss of small parts cover any
drainage holes.
3) The shower unit should be positioned
so that the showerhead cannot be
immersed in the bath or shower tray
when hanging down.
Where holes are to be drilled into a
tiled surface a suitable tile or glass drill
bit should be used to make a hole
through the tile only. The hole made
through the tile should be 0.5mm larger
than the hole in the wall.
These installation instructions assume
mounting onto a solid masonry wall.
For other types of structure please
amend the procedure accordingly.
Plumbing
1) Remove the front cover of the shower
unit complete with the two control knobs
by removing the two screws securing it to
the back plate.Remove the ‘trim plate’
at the bottom right-hand side of unit to
allow easy access for the plumbing work.
2) Position the shower unit on the wall in
the desired place and mark the location
of the fixing holes.
3) Determine the direction of the inlet water
supply: bottom (rising), top (falling) or
back inlet. The shower unit is supplied
with a swivelling push-fit inlet elbow. This
elbow should be rotated to match the
desired direction of water supply entry to
the unit. Carefully remove the appropriate
plastic break-out from the unit’s back
plate so that the mains water supply
pipe can be routed into the unit.
4) Carefully drill the holes using a 5.5mm
masonry drill (note when drilling though
tiles first use a glass or tile drill bit of 6mm
diameter to drill a hole through the tile).
5) Insert the plugs provided through the
hole in the tile and fix the unit to the
wall using the screws supplied. Do not
tighten the screws fully at this stage.
6) Turn off the water supply at the isolating
stop tap.
7) Bring the mains water supply using
15mm copper or stainless steel pipe to
the shower unit so that it enters through
the hole in the back plate.
8) Before connecting the shower unit, flush
out any debris in the new pipework by
connecting a hose to the end of the
mains supply pipe and running the mains
water until all the debris has cleared.
9) After flushing out, turn off the
water supply and connect
the pipe to the shower inlet.
Having inserted the inlet
pipe into the elbow, secure
the joint by finger tightening
the locking device, rotating
in a clockwise direction.
10) Make sure that the shower unit is
positioned squarely on the wall and
tighten the fixing screws. Tighten all
plumbing joints and turn on the water
supply to check for leaks. With the unit
firmly fixed to the wall and the
pipework free from leaks, dry the
shower area in preparation for the
electrical installation.

Assembly
Part the mounting bracket
assembly so that the fixing plate
is separate from the cover.
Establish the best position for the
riser rail, and mark the wall for
the lower mounting bracket.
Make allowances for the tallest person likely to
use the shower regularly.
When drilling through tiles use a
suitable glass or tile drill of 6mm
diameter to drill through the tile
only. Use a no 10/5.5mm masonry
drill to make a hole 35mm deep,
and fit the wall plug. (NB some
wall constructions may require the use of
different types of wall fixings to those supplied).
Screw the lower bracket base to the wall.
Locate the crimped end of
the riser rail (Figure 4) into the
mounting bracket, then fit
the upper bracket to the rail.
Ensure the rail is vertical, then
mark the wall for the fixing.
NOTE if it is necessary to
shorten the rail, use a junior
hacksaw to cut the excess
material from the plain end
of the rail (the uncrimped
end).
Insert the end pieces of the
height adjuster into the body
section matching the letters A
and B (moulded into the ends
of each piece) and twist so the
pieces lock together.
With the shower head holder in
the upright position (widest
opening at the top) and the
lever in the open position, slide
the assembly onto the rail.
Tighten the height adjuster to
the rail by twisting the lever.
Insert the rail into the bottom
and top brackets and screw
the upper mounting bracket
in place. Clip the end caps
onto the mounting brackets.
Electrical
Switch off the water supply at the isolating
valve before connecting the wiring to the
unit.
The shower unit must be permanently
connected to the electricity supply, direct
from the consumer unit via a double pole
linked switch with a minimum contact gap
of 3mm.
It is recommended that the switch be a
cord operated type with neon on/off
indicator, otherwise the switch should be
readily accessible, clearly identifiable and
out of reach of any person using the shower.
The wiring to the switch must be done
without the use of a plug or socket outlet.
The cable used must be of a diameter
suitable for the power rating of the
shower selected. The table below may
be used as a guide to the cable
requirements. If in doubt consult a
qualified electrician.

the top of the shower is in the cold
position and that the electrical supply
has been isolated at the double pole
isolating switch.
2) With the water supply to the unit turned
on, turn the bottom temperature
control knob anti-clockwise to the full
cold position. No water should exit the
shower either from the handset or from
any other part of the shower unit.
3) Switch on the electrical supply at the
double pole isolating switch, the power
neon on this switch should light.
4) Turn the top power selector knob to the
‘Cold’ setting (Solid Blue Symbol).
5) Start the shower by pressing the
start/stop button. Water should start
to flow from the handset within a
few seconds.
6) Check that water flows freely from the
shower within a few seconds. The
water from the showerhead will be at
full force and at a cool temperature.
7) Now turn the top power selector knob
to the ‘Low’ setting (Outline Red
Symbol). Allow a few seconds for the
warmer temperature to reach the
showerhead – this shows that the ‘Low’
power is operating correctly.
8) Now turn the top power selector
knob to the ‘High’ setting (Solid Red
Symbol). The temperature at the
showerhead will rise further – this
shows that the full power setting is
operating correctly.
9) Turn the bottom temperature control
knob clockwise for hotter water and
anti-clockwise for cooler water. Allow
a few seconds between selections for
the temperature change to reach the
showerhead. Note that selecting a
hotter setting in the temperature
control reduces the flow of water.
10) Press the Stop/Start button to stop water flow.
A small amount of water may continue to
drip from the unit as water drains from the
pipe-work. This should stop within a few
minutes.
The commissioning procedure is now
complete.

Operation
‘Power indicator’:
The power indicator on the shower unit
will light when the shower is switched
on and water is flowing on one of the
two heat settings. The indicator does
not light on the cold setting.
‘Auto Reset Indicator’
The Auto Reset Indicator will illuminate
if an overheat temperature is sensed
during operation. Once activated the
electricity supply to the elements is
switched off until the unit has cooled
sufficiently, where upon power to the
elements will be restored.
Once the indicator has lit, allow the cold
water to flow through the unit so that
normal operation can resume as quickly
as possible. At the next convenient time
the shower head should be cleaned to
remove any particles or limescale

6) Switch off the electricity supply using
the pull-cord or wall mounted switch.
SECTION 5
Looking after your shower
The showerhead should be cleaned
periodically to remove limescale or other
particles which will reduce the performance
of the shower. The frequency of cleaning
will vary according to the local water
quality. In hard water areas cleaning will
be needed more often than in soft water
areas. A liquid non-abrasive bathroom
cleaner may be used on external surfaces
of the handset.
Rub-clean showerheads may be rubbed
lightly to remove scale as required. Over time
build-up of limescale requires the showerhead
to be cleaned more thoroughly, as follows.
1) Use a liquid non-abrasive bathroom
cleaner on external surfaces of the
handset.
2) Engage the key into the spray cartridge
recesses and turn anti-clockwise to
unscrew.
3) Remove the two small black ‘O’ rings
from the rear of the spray cartridge,
and rinse the ‘O’ rings clean.
4) Brush the spray plate with a stiff bristled
brush, if necessary immerse and soak
the spray plate for several hours in a
proprietary limescale remover. Rinse off
all traces of limescale and limescale
remover from the showerhead.
5) Replace the two black ‘O’ rings on the
rear of the spray cartridge and refit the
cartridge to the showerhead tightening
with the key.'
SECTION 6
Trouble shooting
Before calling our customer service
department please use the table to
determine likely causes of the problem:
NOTE Under normal operation the shower
heats the water as it passes through the
unit. The temperature of the water is
affected by the temperature of the water
in the mains cold water supply and the
speed with which the water flows through
the unit. It is therefore normal for the water
coming out of the shower to change
temperature through summer and winter
months where the mains water temperature
changes. It is also normal for the water
temperature to vary when other water
appliances are being use in the home as
these vary the water flow to the shower
unit. Do not under any circumstances
cover the showerhead or prevent or
restrict water leaving the showerhead or
unit. It is important to keep the showerhead
clean, removing all lime scale and any
other dirt blocking the holes of the
showerhead. The showerhead must be
cleaned as described in section 5 ‘looking
after your shower’.
SECTION 7
Maintenance
Disconnect from mains electricity supply
before removing front cover.
All maintenance should only be carried
out by a qualified service engineer.
