FOR THE INSTALLER:
DEFAULT PLUMBING SETTING: The shower unit is supplied for right
hand mains water connection. To plumb the unit from the left of the
shower back plate you must remove the blanking cap by sliding off the
metal retaining clip and ret to the right hand side of the unit ensuring the
metal retaining clip is retted and pushed rmly into the groove. Whilst
leak testing the installation please ensure that there is NO water leaks
from this area. See Section 8: Plumbing Connections.
IMPORTANT: To comply with water regulations, building regulations or
any specic local water company regulations and in accordance with BS
EN 806 a double check valve should be tted where it is possible that the
shower head may come into contact with used water, for example in the
bath or a shower tray.
IMPORTANT: Check that there are no hidden cables or pipes before
drilling holes for the wall plugs. Chose a at piece of wall to avoid the
possibility of distorting the back plate and making the front cover a poor
t. Exercise great care when using power tools near water. The use of a
residual current device (RDC) is recommended.
IMPORTANT: Before connecting the water supply to the shower unit
the water supply pipe should be ushed out to remove all debris. After
ushing the pipe work make the connection to shower inlet and ensure
the shower is positioned squarely on the wall and all xing screws are
tightened.
IT IS VERY IMPORTANT to ensure that the terminal block screws are
FULLY tightened and that no cable insulation is trapped under the
screws. The earth continuity conductor of the electrical installation must
be effectively bonded to earth on the fuse board.
IMPORTANT: Ensure that the ow control knob is turned to FULL ow
and the commissioning instructions are followed before switching the unit
on. This will make sure that the unit is full of water when rst activated.
IMPORTANT: The shower unit MUST be full of water before the heat
settings are used.

4. GENERAL INSTALLATION LAYOUT GUIDE
Plan your installation carefully. Check on
the nearest and most accessible rising
main water supply, this may be beneath
the bath or in the loft, where it feeds the
water storage tank. Use only the cold
rising water main.
Avoid connecting the shower unit if
possible where it will be affected by water
drawn off by another appliance. For
example from the mains feed to the toilet
as this may cause a drop in pressure to a
level that is too low for the shower unit to
work correctly.
A WRAS (water regulations advice
scheme) listed isolating valve must be
tted between the rising main and the
unit to comply with water regulations and
to allow for routine maintenance and
servicing.

Position your shower on the wall so that it
will NOT be in the direct water spray from
the shower handset when xed.
You may wish to consider mounting the
unit so that the shower handset could be
used over a sink for washing hair.
The shower unit should be positioned so
that the shower head cannot be immersed
in the bath or shower tray when hanging
down. A shower hose retainer is supplied
with the accessories (see pages 3
and 10).
The unit can be mounted at a lower level
if required for less abled users and for use
with a shower seat.
The shower unit can be mounted at
a lower level if required for less abled
users and for use with a shower seat.
The installation should comply with the
relevant British Standard covering the
design of buildings to meet the needs of
disabled people. It is important that if this
option is chosen the shower unit must not
be mounted directly in the water spray
from the handset.
Remove the four front cover xing screws
and lift the cover off complete with the
warmer (+) and cooler (-) push buttons and
ow control knob in place.
Note: there is a connector and lead
attached to the control PCB mounted on
the shower back plate. This will require
connecting to inside of the front cover
before completing the installation.
Having decided on the water and cable
entry points and chosen a at piece of
wall hold the shower vertically against the
wall and mark the top two xing holes.
Carefully drill the two holes as marked
using a sharp 5.5mm masonry drill after
rst making certain there are no pipes or
wires behind the proposed holes.
Insert the wall plugs and screws provided
leaving the screw head proud by
approximately 5mm. The shower can now
be hung on these screws.
Make sure that the shower is positioned
vertically now mark and drill the lower
slotted xing hole. Then x the shower to
the wall. Do not fully tighten the screws at
this stage.

9. ELECTRICAL CONNECTIONS
The electrical installation must be in
accordance with the current BS 7671
(I.E.E. wiring regulations) and part P of
the building and / or local regulations.
The shower unit is designed for a single
phase 50 Hz a.c. electrical supply.
ELECTRICAL SPECIFICATIONS
IMPORTANT: The heating elements on
the UK models are manufactured to 240V
specication and will give a lower kW
rating if the voltage supply is below 240V.
The shower unit must be permanently
connected to the electrical supply, direct
from the consumer unit via a double pole
linked switch with a minimum contact
gap of 3 mm. The switch must be readily
accessible and clearly identiable and
sited out of reach of a person using the
shower over a xed bath or shower tray,
unless the switch is pull cord operated.
The wiring must be connected to the
switch without the use of a plug or socket
outlet.
The supply cable size is determined by
the kW rating of the product (as detailed
on the rating plate xed to the back plate)
and the distance between the shower and
the consumer unit. The table below is for
guidance only but will help you choose
the correct cable for your installation.
If you are in any doubt consult an
electrician.
Nominal Power rating at 240V
8.5kW - (40A MCB rating)

IMPORTANT
If the programmes are adjusted following the unit commissioning switch off the
electricity at the isolating switch before removing the front cover taking care not
to damage the PCB ying lead and check correct operation of the shower
after re-tting the front cover.

11. FITTING THE FRONT COVER
IMPORTANT: it is necessary to align the
Multi pin connector and connect the ying
lead from the PCB to the rear of the front
cover.
Hold the front cover carefully and
attach the ying lead from the control
PCB (ensuring that the lock tags are
aligned with the slots on the display
PCB connector) to the rear of the front
cover as illustrated making sure that the
connector pins are fully engaged.
The cover can now be tted and secured
with the four xing screws provided.
Following the installation of the riser rail
(see section 12) attach the exible hose to
the shower outlet positioned centrally on
the back plate making sure that you use
the seal washer provided. The shower is
now ready for commissioning.

12. RISER RAIL FITTING INSTRUCTIONS
1. Establish the height of the riser rail to
suit requirements, taking into account all
users.
2. Remove caps and covers from
brackets.
3. Mark the position of the lower bracket
then drill and plug the wall. If this is
a replacement installation locate the
bottom hole.
4. Fit rail through lower bracket and clamp.
Place the remaining bracket on top of
the rail making sure the slot in the rail is
located in the notch.
a. For a replacement riser x the top
bracket using the existing hole.
b. For a new installation ensure the hole
position is vertically aligned and mark
the wall. Unclamp the lower bracket and
remove the rail then drill and plug the
wall before xing the top bracket into
position.
5. Slide the height adjuster onto the
rail. Tighten to the rail by turning the
locking cap. Then t the soap dish –
dampening the rail will make it easier
to slide on. Finally t the hose retaining
ring onto the bottom of the rail below
the soap dish.
6. Replace the rail assembly through
the lower bracket. Fit the rail into top
bracket ensuring the slot locates into
the notch. Tighten the lower bracket
then ret the bracket caps.
NOTE: The adjustable height adjuster
grips the conical ends of the hose, not the
handle of the showerhead.
CAUTION
Check there are no hidden cables or pipes before drilling holes for wall plugs.
Exercise great care when using power tools near water.
The use of a residual current device (RCD) is recommended.

TIPS
A piece of insulating or masking
tape applied to the wall before
marking out the Fixing holes will
help stop the drill from wandering,
particularly on tiled surfaces. When
working near a basin or bath, insert
the plug in the waste tting so that
small parts cannot be lost.
Take care not to drop accessories or
tools into basin or bath.

13. COMMISSIONING THE SHOWER
IMPORTANT: This MX Thermostatic
shower unit incorporates a commissioning
procedure detailed below. It is important
that this procedure is followed.
1. Make sure that the electricity supply
has been isolated at the double pole
isolating switch.
2. Ensure that the water supply is fully on
at the mains stop cock and isolating
service valve (if tted)
3. Check that water is not leaking from the
bottom of the case.
4. Switch on the electrical supply at the
double pole switch or pull cord. The
power on neon indicator will light at the
switch.
5. On the shower unit press and hold the
warmer (+) and cooler (-) buttons for
a minimum of 3 seconds until COLD
water ows into the shower and through
to the shower handset, and then
release the buttons. When the water is
free owing and all the air has purged
through the system press the start /stop
button and this will stop the water ow.
7. Press the start /stop button, you will
hear a single bleep and the water will
ow freely within a few seconds. The
water ow will start at maximum ow
indicated by 3 LEDs around the ow
button.
NOTE: If the commissioning procedure is
not used the heaters will have a 6 second
delay before they are energised to allow
the water to ll the unit (this only happens
on the rst start up operation).
IMPORTANT: If the button does not
respond ensure that the ying lead from
the PCB has been connected to the back
of the front cover. Ensure front cover
is isolated at the mains supply before
removing.
9. The “Secret Until Illuminated” seven
segment display will activate and
show digit 8 for the Thermostatic Care
model which indicates the FIXED pre-
programmed start up temperature.
The Thermostatic Plus models are
supplied with MEMORY start up
temperature setting which will be as
per the last shower, however it may be
necessary to adjust to digit 8 at initial
start up. On all models the ow starts
at the maximum level clearly indicated
by the 3 illuminated LEDs.
10. The shower will start to heat the water.
A double bleep indicates when the
pre-programmed start up temperature
has been reached. Please note this
could take up to 30 seconds if the
shower is starting from cold. The unit
will automatically adjust the water ow
if required.
11. Check the operation of the
temperature control buttons by
pressing the cooler (-) button once.
The temperature digit will change to
show 7 conrmed by a single bleep (if
audio not de-selected on installation).
Keep pressing the cooler button
repeatedly until the digit reaches 1,
which when stable will give a nominal
outlet temperature of 30 ºC.
IMPORTANT
The shower unit must be full of water before heat settings are used.
