If it is intended to operate the shower in areas
of hard water (above 200 ppm temporary
hardness), a scale inhibitor may have to be
fitted. For advice on the Triton Scale Inhibitor,
contact Triton Customer Service.
The showerhead must be cleaned regularly
with descalent to remove scale and debris,
otherwise restrictions to the flow on the outlet
of the unit will result in higher temperatures
and could also cause the Pressure Relief Device
in the unit to operate.
This product is not suitable for mounting into
steam rooms or steam cubicles.
PLUMBING
The plumbing installation must comply with
Water Regulations, Building Regulations or any
particular regulations as specified by Local
Water Company or Water Undertakers and
should be in accordance with BS 6700.
The supply pipe must be flushed to clear
debris before connecting to the shower unit.
DO NOT solder pipes or fittings within
300mm of the shower unit, as heat can
transfer along the pipework and damage
components.
DO NOT fit any form of outlet flow control as
the outlet acts as a vent for the heater can.

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.
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.

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.
5For 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.
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.

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 ensure activation of 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 for the 9.5kW rated
model.
The maximum static pressure must be no
greater than 1000kPa (10 bar).
If in any doubt, the pressure should be
checked.
Note: If the stated flow rate is not available, it
may not be possible to achieve optimum per-
formance from the unit throughout the year.
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 mini-
mum head of ten metres. Minimum head is the
vertical distance from the base of the cistern
to 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 Triton Customer
Service for advice.
(Fig.5) shows a typical system layout.
Do not use jointing compounds on any pipe
fittings for the installation.

P-001-A
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.

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 25 mm 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.

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.
Note: The control knob is an integral part of the
cover – DO NOT attempt to remove it.
Lift the cover from the backplate. To access the
pipe and cable connections lift off the trimplate
(fig.7).
Entry positions for the mains water are from the
bottom, rear or side. Cable entry is via the top
or rear.
Note: Deviations from the designated entry
points will invalidate product approvals.
If bottom or side surface entry is required for the
mains cold water, then the necessary opening
will need to be cut out in the trimplate (fig.8).
If surface cable entry from the top is required
then a small area will need to be cut out in the
backplate (fig.9).
If installing a feed pipe from the rear, bottom
or side the centre of the inlet valve to the wall
surface is 21 mm (fig.10).
Note: If entry is from the rear, the nut of the
compression fitting will be partially behind the
surface of the wall (fig.10). This area MUST
be left clear when plastering over the pipework
in order to make the nut accessible for future
adjustments.
IMPORTANT: Always seal around the
incoming pipework to prevent water entering
the wall.
After choosing the site for the shower, use the
backplate as a template and mark the three
fixing holes (fig.11).
Drill and plug to suit the fixing screws supplied.
(The wall plugs provided are suitable for most
brick walls – use an appropriate masonry drill, but
if the wall is plasterboard or a soft building block,
you must use suitable wall plugs and a suitable

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 15 mm copper, stainless steel or plastic pipe
using a 15 mm x 15 mm brass elbow or straight
coupler 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.
Note: At this stage no water can flow through
the unit.
W-004-A
WARNING!
The outlet of the shower acts as a
vent and MUST NOT be connected to
anything other than the hose and
showerhead supplied.

WARNING!
Before normal operation of the
shower, it is essential the following
commissioning procedure is completed
correctly.
When the electricity supply to the shower is
switched on at the isolating switch, the POWER
indicator will light.
To start the shower
Press the START/STOP button and water will
begin to flow.
Note: The default start up setting is the HIGH
setting.
To stop the shower
Press the START/STOP button and the phased
shutdown will begin. Water will cease to flow
after a few seconds.
To use the control buttons
There are two control buttons – HIGH/
ECONOMY and COLD (fig.20).
The upper button is for switching between the
HIGH and ECONOMY power setting.
The HIGH setting allows the highest flow
achievable for your preferred temperature. This
setting should normally be regarded as optimum
shower performance throughout the year.
The ECONOMY setting uses less energy when
the ambient mains water temperature is high
during hot months.
Note: When starting the shower, the default
setting is HIGH. The upper button alternates
between the two settings. Press the button
once to select the ECONOMY setting; press the
button again to reselect HIGH.
Temperature adjustment at this setting is via the
temperature control.
The lower button is for COLD water only.
Adjusting the temperature control at this setting
will only increase or decrease the flow of the
water from the showerhead. (It will not alter the
water temperature.)

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.21).
After finding a suitable showering temperature,
the temperature control can be left as the
normal setting and should only need altering
to compensate for seasonal changes in ambient
water temperature.
Note: The preferred position on ECONOMY will
give a different temperature to the same position
on HIGH.
To decrease the shower temperature
Turn the temperature control anti-clockwise; this
will increase the flow of water through the shower.
To increase the shower temperature
Turn the temperature control clockwise; this will
decrease the flow of water through the shower.
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.

Operating functions
OPERATING FUNCTIONS
Power on indicator (fig.22)
When the electricity supply to the shower is
switched on at the isolating switch, the POWER
indicator will light.
Low pressure indicator (fig.22)
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. The shower will operate
on the COLD setting until there is adequate
water pressure which automatically restores the
power to the elements.
Selector mode indicators (fig.23)
Next to each control button there is an indicator
that lights when the button is pressed, indicating
which shower mode is in operation.
On the HIGH setting both indicators next to the
upper button are lit. On the ECONOMY setting
the lower indicator only is lit.
Phased shutdown
In use, when the START/STOP button is pressed,
power is switched off to the elements. Water
will continue to flow for a few seconds, flushing
out any remaining hot water. This makes sure
the next immediate user will not receive a slug
of hot water if standing under the showerhead
when starting the shower.
Temperature limiter
During normal operation if an overheat
temperature is sensed, power to the elements
will be reduced. Water will continue to flow.
When the temperature has cooled sufficiently
power to the elements will be automatically
restored to the setting at the time of
interruption.
