ADVICE TO USERS
The following points will help you understand
how the shower operates:
a. The electric heating elements operate at a
constant rate at your chosen power setting.
It is the rate of the water passing through
the heater can which determines the water
temperature. (The slower the flow, the hotter
the water becomes; the faster the flow, the
cooler the water).
b. During winter the mains water supply will
be cooler than in the summer, so the flow
rate will vary between seasons at any one
temperature setting. At different times of the
year you may have to adjust the position of
the temperature control to maintain your
desired temperature setting.
c. The stabiliser valve minimises variations in
shower temperature during mains water
pressure changes. If changes in shower
temperature are experienced during normal
use, it will most likely be caused by the
water pressure falling near to or below the
minimum level. The drop in pressure may
be due to water being drawn off at other
points in the house whilst the shower is in
use. If pressure drops appreciably below
the minimum, the heating elements will
automatically cut out.
If ever the water becomes too hot and you
cannot obtain cooler water, first check that
the sprayplate in the showerhead has not
become blocked.
DO NOT place items such as soap or shampoo
bottles on top of the unit. Liquid could seep
through the joint between the cover and
backplate, and possibly damage the sealing
rubber.
IMPORTANT: When first installed the unit
will be empty. It is essential the unit should
contain water before the elements are
switched on. It is vital that the commissioning
procedure is followed. Failure to carry out
this operation will result in damage to the
unit and will invalidate the guarantee.
Replacement parts can be ordered from Customer Service. See
‘spare parts’ for details and part numbers.
Due to continuous improvement and updating, specification
may be altered without prior notice.

CIRCUIT PROTECTION
Fig.4 Schematic of installation circuit
ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufficient for the
amperage required.
The following notes are for guidance only:
1The shower must only be connected to a
230-240V ac supply. If you are installing a
shower with a kilowatt rating above 9kW, it
is advisable to contact the local electricity
supply company.
1.1 The electrical rating of the shower is shown
on the rating label (Fig.3) within the unit.
2Before making any sort of electrical
connection within the installation make
sure that no terminal is live. If in any doubt,
switch off the whole installation at the mains
supply and remove the correct fuse.
3The shower must be connected to its own
independent electrical circuit. IT MUST NOT
be connected to a ring main, spur, socket
outlet, lighting circuit or cooker circuit.
3.1 The electrical supply must be adequate for
the loading of the unit and existing circuits.
4Check your consumer unit (main fuse box)
has a main switch rating of 80A or above
and that it has a spare fuse way which will
take the fuse or Miniature Circuit Breaker
(MCB) necessary for the shower (Fig.4).
4.1 If your consumer unit has a rating below
80A or if there is no spare fuse way, then the
installation will not be straightforward and
may require a new consumer unit serving
the house or just the shower.
4.2 You will need to contact the local electricity
company. They will check the supply and
carry out what is necessary.
5 For close circuit protection DO NOT use a
rewireable fuse. Instead use a suitably rated
Miniature Circuit Breaker (MCB) or cartridge
fuse (see Table A).
5.1 A 30mA residual current device (RCD)
MUST be installed in all UK electric and
pumped shower circuits. This may be part of
the consumer unit or a separate unit.

*The method below may be used by
installers to determine the approximate
size of the incoming cable.
1. Measure the width of an individual strand,
and half that measurment to find (r),
e.g: 1.34mm ÷ 2 = (r) 0.67mm
2. Multiply (r) x (r) x 3.14,
e.g: (r) 0.67 x (r) 0.67 x 3.14 = 1.41mm2
3. Multiply this by the number of wire strands
(usually 7), e.g: 1.41mm2x 7 = 9.87mm2.
4. The number obtained would suggest
10mm2wiring.
*PLEASE NOTE: If unsure, consult a qualified Electrician.
6A 45 amp double pole isolating switch with
a minimum contact gap of 3 mm in both
poles must be incorporated in the circuit.
6.1 It must have a mechanical indicator showing
when the switch is in the OFF position, and
the wiring must be connected to the switch
without the use of a plug or socket outlet.
6.2 The switch must be accessible and clearly
identifiable, but out of reach of a person
using a fixed bath or shower, except for the
cord of a cord operated switch, and should
be placed so that it is not possible to touch
the switch body while standing in a bath or
shower cubicle. It should be readily accessible
to switch off after using the shower.
7Where shower cubicles are located in any
rooms other than bathrooms, all socket
outlets in those rooms must be protected by
a 30mA RCD.
8The current carrying capacity of the cable
must be at least that of the shower circuit
protection (see Table B).
8.1 To obtain full advantage of the power
provided by the shower, use the shortest
cable route possible from the consumer unit
to the shower.
8.2 It is also necessary to satisfy the disconnection
time and thermal constraints which means
that for any given combination of current
demand, voltage drop and cable size, there is
a maximum permissible circuit length.
9The shower circuit should be separated from
other circuits by at least twice the diameter
of the cable or conduit.
9.1 The current rating will be reduced if the
cabling is bunched with others, surrounded
by thermal loft or wall insulation or placed
in areas where the ambient temperature
is above 30°C. Under these conditions,
derating factors apply and it is necessary to
select a larger cable size.
9.2 In the majority of installations, the cable
will unavoidably be placed in one or more
of the above conditions. This being so, it is
strongly recommended to use a minimum
of 10mm cabling throughout the shower
installation.
9.3 In any event, it is essential that individual
site conditions are assessed by a competent
electrician in order to determine the correct
cable size and permissible circuit length.

WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations/Bylaws.
To guarantee activating the heating elements,
the shower must be connected to a mains water
supply with a minimum running pressure of
100kPa (1.0 bar) at a minimum flow rate of nine
litres per minute. The maximum static pressure
must be no greater than 1 000kPa (10 bar).
Note: If the stated flow rates are not available,
it may not be possible to achieve the best
performance from the unit throughout the year.
For guidance on the running and static pressures
contact the local Water Authority or consult a
competent plumber.
During periods of high ambient temperatures it
may be necessary to select a low power setting
to achieve your preferred shower temperature.
The water supply can be taken from a cold
water storage cistern provided there is a
minimum head of ten metres above the
showerhead. It must be an independent supply
to the shower only.
If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service for
advice.
Fig.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.

SITING OF THE SHOWER
IMPORTANT: If installing onto a tiled wall
always mount the unit on the surface of the
tiles. NEVER tile up to the unit.
Refer to fig.6 for the correct siting of the
shower. Position the unit where it will NOT be in
direct contact with water from the showerhead.
Position the shower unit vertically.
Allow enough room between the ceiling and the
shower to access the cover top screws. Leave
enough space between the left-hand side of the
unit and the wall to allow access to the pressure
relief device (PRD) in the future.
Note: Water regulations require the showerhead
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 gel
hanger/hose guide will in most cases meet this
requirement, but if the showerhead 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 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
showerhead which can cause the PRD to
operate.
When commissioning, the showerhead 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.
Fig.6 Diagrammatic view (not to scale)
WARNING!
The shower MUST NOT be positioned
where it will be subjected to freezing
conditions.
IMPORTANT: 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.

FITTING THE SHOWER TO THE WALL
Note: The control knobs are an integral part of
the cover – DO NOT attempt to remove them.
Lift the cover from the backplate (fig.7) to
access the pipe and cable connections then lift
off the trimplate.
Entry positions for the mains water are from the
bottom, rear or right. Cable entry is via the top
or rear.
Note: Deviations from the designated entry
points will invalidate product approvals.
If bottom or right surface entry is required
for the mains cold water, then the necessary
opening will need to be cut out in the cover
(fig.8) and the trimplate (fig.9).
Fig.7

WARNING!
Check there are no hidden cables or
pipes before drilling holes for wall
plugs. Use great care when using
power tools near water. The use of
a residual current device (RCD) is
recommended.

If surface cable entry from the top is required
then a small area will need to be cut out in the
backplate (fig.10).
If installing a feed pipe from the rear or bottom,
the centre of the inlet valve to the wall surface is
21mm (fig.11).
Note: If entry is from the rear, the nut of the
compression fitting will be partially behind the
surface of the wall (fig.11). This area MUST
be left clear when plastering over the pipework
in order to make the nut accessible for future
adjustments.
After choosing the site for the shower, use the
backplate as a template and mark the three
fixing holes (fig.12).
Drill and plug the wall.
(An appropriate drill bit should be used. If the
wall is brick, plasterboard or a soft building block,
appropriate wall plugs and screws should be
fitted).
Screw top fixing screw into position leaving the
base of the screw head protruding 6mm out
from the wall.
Hook the backplate over the top screw and
fit the bottom fixing screw into position. DO
NOT fully tighten the screws at this stage,
as the fixing holes are elongated to allow for
out of square adjustment after the plumbing
connections have been completed.

PLUMBING CONNECTIONS
Plumbing to be carried out before wiring
DO NOT use jointing compounds on any pipe
fittings for the installation.
DO NOT solder fittings near the shower unit
as heat can transfer along the pipework and
damage components.
Compression fittings MUST be used to connect
to the inlet of the shower. (Push-on fittings must
NOT be used as full engagement cannot be
guaranteed).
Note: An additional stopvalve (complying with
Water Regulations) MUST be fitted in the mains
water supply to the shower as an independent
means of isolating the water supply should
maintenance or servicing be necessary.
IMPORTANT: Before completing the
connection of the water supply to the inlet
of the shower, flush out the pipework to
remove all swarf and system debris. This can
be achieved by connecting a hose to the
pipework and turning on the mains water
supply long enough to clear the debris to
waste.
Procedure
Turn off water supply either at the mains
stopvalve or the isolating stopvalve. Connect the
mains water supply to the inlet of the shower
via 15mm copper, stainless steel or plastic pipe
using a 15mm x 15mm elbow compression
fitting.
DO NOT use excessive force when making these
connections.
Make sure the backplate is square on the wall
and tighten the two retaining screws which hold
it to the wall.
Turn on the mains water supply and check for
leaks in the pipework connection to the shower.
IMPORTANT: Using a suitable sealant,
always seal around the incoming pipework to
prevent water entering the wall.
Note: At this stage no water can flow through
the unit.
WARNING!
The outlet of the shower acts as a
vent and must NOT be connected to
anything other than the hose and
showerhead supplied.

Live cable to terminal marked L
IMPORTANT: Fully tighten the terminal
block screws and make sure that no cable
insulation is trapped under the screws. Loose
connections can result in cable overheating.
Note: The supply cable earth conductor must
be sleeved. The outer sheath of the supply cable
must be stripped back to the minimum.
The supply cable must be secured either by
routing through conduit or in trunking or by
embedding in the wall, in accordance with
current IEE regulations.
The use of connections within the unit, or other
points in the shower circuit, to supply power to
other equipment i.e. extractor fans, pumps etc.
will invalidate the guarantee.
DO NOT switch on the electricity supply until

COMMISSIONING
IMPORTANT: The first operation of
the shower is intended to flush out any
remaining unit debris, and to make sure
the heater unit contains water before the
elements are switched on.
This operation must be carried out with
the flexible hose screwed to the outlet but
WITHOUT the showerhead attached.
The COLD position must be used. Make sure the
outlet from the flexible hose is directed to waste.
Before turning on the electric and mains water
supplies to the shower, check that the power
selector is in the COLD position (fig.21) and
the temperature control is turned to position
‘10’, the minimum flow position (fig.21).
Note: Failure to turn the control to ‘10’ may
cause the PRD to operate.
Turn on the electric and mains water supplies to
the shower.
Press the START/STOP button (fig.21) and wait
until water starts to flow from the flexible hose.
Slowly turn the temperature control fully
anti-clockwise to ‘1’, the maximum flow
position (fig.22).
It will take about thirty seconds for a smooth
flow of water to be obtained while air and any
debris is being flushed from the shower.
When there is a smooth flow of water turn the
temperature control from ‘1’ to ‘10’ and back
again several times to release any trapped air
within the unit.
Once flushing out has been completed, stop the
water flow by pressing the START/STOP button.
Fit the showerhead to the flexible hose and
place in the showerhead holder.
The shower is now ready for normal operation.

OPERATING THE SHOWER
To start the shower
Press the START/STOP button and water will flow.
To stop the shower
Press the START/STOP button once more and
water will cease to flow.
To use the power selector
The power selector has three positions – COLD,
ECONOMY and HIGH (fig.23).
The blue symbol is for COLD water only.
Adjusting the temperature control at this setting
will only change the force of the water from
the showerhead. (It will not alter the water
temperature).
The grey symbol is the ECONOMY setting for
using less energy when the ambient mains water
temperature is high during warmer months.
Temperature adjustment at this setting is via the
temperature control.
Note: If the stated flow rate required for the
unit cannot be met due to low water pressure,
it will be necessary to operate the unit on this
setting during the warmer months because of
flow rate limitations entering the unit.
The red symbol is the HIGH power setting
which allows the highest flow achievable for
your preferred temperature. This setting should
normally be regarded as optimum shower
performance throughout the year. Temperature
adjustment at this setting is via the temperature
control.

To adjust the shower temperature
The water temperature is altered by increasing
or decreasing the flow rate of the water
through the shower via the temperature control
(fig.23).
After obtaining your showering temperature, the
number can be left as the normal setting and
should only need altering to compensate for
seasonal changes in ambient water temperature.
Note: The preferred number on ECONOMY
will give a different temperature to the same
number position on HIGH.
To decrease the shower temperature
Turn the temperature control anti-clockwise;
this will increase the flow of water through
the shower therefore decreasing the water
temperature, and is indicated by lower numbers.
To increase the shower temperature
Turn the temperature control clockwise; this will
decrease the flow of water through the shower
therefore increasing the water temperature, and
is indicated by higher numbers.
Note: It is advisable to be certain that the
showering temperature is satisfactory by testing
with your hand before stepping under the
showerhead. There will always be a time delay
of a few seconds between selecting a flow rate
and the water reaching the stable temperature
for that flow rate.
CAUTION: It is recommended that persons
who may have difficulty understanding or
operating the shower controls should not
be left unattended while showering. Special
consideration should be given to young
children and the less able bodied.
WARNING!
After any servicing of mains water
supply, always make sure the unit is
started on COLD in order to purge
any air in the pipework.
Note: In normal use, it is in order to leave
the water supply permanently on to the
shower unit, but as with most electrical
appliances, the unit must be switched
off at the isolating switch when not
in use.

OPERATING FUNCTIONS
Power on indicator (fig.24)
When the electricity supply to the shower is
switched on at the isolating switch, the neon
power indicator will light.
Low pressure indicator (fig.24)
If this indicator lights, this means the water
pressure has fallen below the minimum required
for correct operation of the shower, resulting in
the low pressure cut-out operating. This switches
off power to the heating elements preventing
any undue temperature rises (water will continue
to flow). Power will automatically be restored
when adequate water pressure returns.
Temperature limiter
During normal operation if an overheat
temperature is sensed power to the elements
will be reduced, although water will continue
to flow. When the temperature has cooled
sufficiently, power to the elements will be
automatically restored to the settings at the time
of interruption.
Safety cut-out
The unit is fitted with a non-resettable
thermal cut-out safety device. In the event of
abnormal operation which could cause unsafe
temperatures within the unit, the device will
disconnect the heating elements. It will require a
visit from a qualified engineer to determine the
nature of the fault and replace the safety device,
once the unit has been repaired.

CLEANING THE INLET FILTER
It is recommended that the filter is periodically
cleaned in order to maintain the performance of
the shower. It is essential that this operation is
carried out by an installer or service engineer.
IMPORTANT: Before servicing, switch off
both the electricity supply and water supply
at the mains.
The inlet filter is situated at the bottom of the
inlet pipe (fig.25).
To gain access to the filter, remove the trimplate
and then unscrew the retaining nut from the
bottom of the inlet pipe.
When cleaning the filter, DO NOT use a sharp
object, as it will cause damage. It is preferable to
use an old toothbrush or similar.
