GENERAL 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 water supply will be cooler
than in the summer. 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.
NOTE: 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.
ADVISORY - CLEANING
It is recommended that all products
are cleaned using warm, soapy water.
DO NOT use abrasive or aggressive
chemical cleaning products as this may
affect the product surface nish and
invalidate your guarantee.
IMPORTANT ADVICE TO USERS
COMMISSIONING ADVICE
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.
Please read this book thoroughly and familiarise yourself with all instructions before
commencing installation and keep it for future reference
The shower installation MUST be carried out by a suitably qualified person, in the sequence of
this instruction book.

CIRCUIT PROTECTION
Fig.4Schematic of installation circuit
ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufcient 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 toaring 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
able, but out of reach of a person
uxed 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 (see
Table B), 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.

11
SITING OF THE SHOWER
SITING OF THE SHOWER
The installation must be in accordance with
Water Regulations/Bylaws - see page 7 and
below for water specifications.
• To ensure activation of the heating elements,
the shower must be connected to a cold
water supply which is gravity fed from a
static cold water storage cistern with a
minimum capacity of 114 litres (25 gallons)
that will deliver a MINIMUM of 8 litres per
minute to the shower water inlet.
• There must be a maximum head of water of
10 metres and a minimum head of 8 cm as
measured between the bottom of the cistern
and the top of the shower unit. There must
be no other cold water draw-offs between
the cistern and the unit and the pipe must
not supply water to any other tap or fitting
at a lower level.
• Pipework to the shower unit MUST be
routed where it remains below the level of
the water cistern.
• If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service
for advice.
• If the stated flow rates are not available,
it may not be possible to achieve optimum
performance from the unit throughout
the year.
• During periods of high ambient temperatures
it may be necessary to select the economy
power setting to achieve your preferred
shower temperature.
Fig.5 shows a typical system layout.
• 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.
• Mark out entry points and routing of the
water and electric supplies into the shower.

Fig.5
ADVISORY NOTE
The supply pipe from the cistern should be
on the opposite side to the oat operated
valve to prevent air being drawn into the
pipe when the cistern is lling.
If it is intended to operate the shower in
hard water areas (above 200 ppm temporary
hardness) a scale inhibitor should be tted.

12
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 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’.
• If the riser kit is supplied with a ‘soap dish
hose retainer’ or bespoke ‘hose retainer’, it
will in most cases meet this requirement. If
the showerhead 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 showerhead.
This may cause the PRD to operate.
• When commissioning, the showerhead
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 stop valve.
Contact Customer Service for advice on
replacing the PRD.
SITING OF THE SHOWER 4

PLUMBING INSTALLATION
PLUMBING INSTALLATION
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 (fig.7).
Push-on fittings must NOT be used as full
engagement cannot be guaranteed.
• If installing a feed pipe from the back or
bottom, the centre of the inlet valve to the
wall surface is 21mm (fig.7).
NOTE: If entry is from the back, the nut of the
compression fitting will be partially behind the
surface of the wall. This area MUST be left clear
when plastering and tiling around the pipework
in order to make the nut accessible for future
adjustments (fig.7).
NOTE: A fullway isolating valve (complying with
Water Regulations) must be fitted in the 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 water supply
long enough to clear the debris to waste.
IMPORTANT: A suitable sealant should always
be used to seal around the incoming pipework to
prevent water entering the wall.
IMPORTANT INFORMATION
The outlet of the shower acts as a vent
and must not be connected to anything
other than the hose and showerhead
supplied.

Fitting Procedure
• Turn off water supply at the isolating stop
valve.
• Temporarily connect the water supply to the
inlet of the shower using a 15mm x 15mm
compression fitting.
• Use the backplate as a template making sure
it is level and mark the fixing holes (fig.9).
• Remove the unit from the wall. Drill and
plug the wall. An appropriate drill bit should
be used. If the wall is plasterboard or a soft
building block, appropriate wall plugs should
be fitted.
• Screw the top middle (no2) 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 other fixing screws into position, but
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 connection has been completed.
• Connect the water supply to the inlet DO
NOT use excessive force when making the
connection.
• Make sure the backplate is square on the
wall and tighten the retaining screws which
hold it in place.
• Turn on the water supply and check for leaks
in the pipework connection to the shower.
IMPORTANT: A temporary locking screw is
fitted to the power selector spindle at the factory
(fig.10). This is to make sure the spindle is held
in the COLD position whilst the commissioning
procedure is carried out.
DO NOT remove the locking screw before
the commissioning procedure has been
successfully completed.

Earth cable to terminal marked
Neutral cable to terminal marked N
• Fig.12 shows a schematic wiring diagram.
IMPORTANT: When connecting the cable 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 use of connections within the unit or
other points in the shower circuit to supply
power to other equipment i.e. extractor fans,

TO DO BEFORE FITTING THE COVER
1. Make sure the water supply is turned on to
the shower.
2. Open the bleed screw on the pump unit
(fig.13) by rotating two revolutions. When
water flows from the opening, this indicates
that any trapped air is vented and that the
pump unit is primed. The bleed valve MUST
now be closed by rotating in the opposite
direction.
3. Make sure the temporary locking screw on
the power selector is in place - see fig.10.

COMMISSIONING PROCEDURE
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.
Make sure the outlet of the flexible hose is
directed to waste.
1. Before turning on the electric supply to the
shower, make sure that the power selector is
at the ‘COLD‘ position and the temperature
control is turned to fully anti-clockwise to
‘MAXIMUM’ flow (fig.17).
2. Turn on the electric supply to the shower at
the isolating switch.
3. Press the Start/Stop button and wait until
water starts to flow from the flexible hose. At
least 30 seconds
4. Once flushing out has been completed, stop
the water flow by pressing the Start/Stop
button.
WARNING
Before normal operation of the shower, it
is essential the following commissioning
procedure is completed correctly.
