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 mains 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.
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.
NOTE: If ever the water becomes too hot and
you cannot obtain cooler water, first check
that the sprayplate in the shower head 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.
To check the product suitability for commercial and multiple installations, please contact Triton’s
specification advisory service before installation. Please see back of book for contact information.
Please read this book thoroughly and familiarise yourself with all
instructions before commencing installation and keep it for future reference.

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 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
2
on the rating label (Fig.3) within the unit.
Before 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 3mm 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.

SITING OF THE SHOWER
The installation must be in accordance with
Water Regulations/Bylaws - see page 2 for
water specifications
• 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.
NOTE: The control knobs are an integral part of
the cover. Do not attempt to remove them.
• Lift the cover from the backplate and remove
the trimplate.
• 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
shower head. 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.

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 shower head 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 ‘soapdish
hose retainer’ or bespoke ‘hose retainer’, it
will, in most cases, meet this requirement. If
the shower head 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 shower head.
This may cause the PRD to operate.
• When commissioning, the shower head
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 stopvalve.
Contact Customer Service for advice on
replacing the PRD.
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.
IMPORTANT: If installing onto a tiled wall,
ALWAYS mount the unit on the surface of
the tiles. NEVER tile up to the unit.

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.
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.
IMPORTANT INFORMATION
The outlet of the shower acts as
a vent and must not be connected
to anything other than the hose
and shower head supplied.

ELECTRICAL INSTALLATION
IMPORTANT: Switch off the electricity supply at
the mains before proceeding.
• The supply cable MUST be secured either by
routing through conduit, in trunking, or by
embedding in the wall, in accordance with
IEE regulations.
NOTE: Conduit entry can only be from rear.
NOTE: Deviations from the designated entry
points will invalidate product approvals. The
cable entry points are listed on page 3.
• Seal around rear entry cable to prevent water
ingress into the wall.
FIT TO THE WALL & CONNECT THE

Fitting Procedure
• Turn off water supply either at the mains
stopvalve or the isolating stopvalve.
• Temporarily connect the mains 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.10).
The top and one of the bottom two fixing
holes should be sufficient to hold the shower.
• 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 fixing screw into position
leaving the base of the screw head protruding
around 6mm out from the wall. Hook the
backplate over the top screw and fit the
bottom fixing screw/s into position.
• Connect the mains 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 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.
IMPORTANT: A suitable sealant should always
be used to seal around the incoming pipework to
prevent water entering the wall.
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 when
using power tools.

water supplies to the shower, make sure that
the power selector is at the OFF position
and the temperature control is turned fully
clockwise to MINIMUM flow (fig.17).
2. Turn on the mains water supply to the shower
at the isolating stopvalve and then turn on the
electric supply to the shower at the isolating
switch.
3. Turn the power selector to COLD (fig.17)
and wait until water starts to flow from the
flexible hose.
4. Slowly rotate the temperature control fully
anti-clockwise to the maximum flow
position (fig.18). It will take about thirty
seconds for a smooth flow of water to be
obtained while air and any debris is flushed
from the shower.
• When a smooth flow of water is obtained,
rotate the temperature control from
minimum to maximum several times to
release any trapped air within the unit.
•Once flushing out has been completed turn
the power selector to OFF.
• Fit the shower head to the flexible hose and
place in the shower head holder.
The shower is now ready for normal operation.
WARNING
Before normal operation of the shower, it
is essential the following commissioning

OPERATING THE SHOWER (fig.19)
Make sure the commissioning procedure
has been carried out.
To start the shower
• Turn the power selector to either Cold,
Economy or High and the water will flow.
To stop the shower
• Turn the power selector to the OFF position.
• After stopping the unit MUST be isolated via
the 45amp-isolating switch.
To use the power selector
The power selector has three positions - COLD,
ECONOMY and HIGH.
• Cold setting - single blue line: The cold
setting does not provide any heat from the
heater can to the incoming water.
• Economy setting - single red line: Uses
only one of the elements within the heater
can.
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.
• High setting - double red lines: Uses both
of the elements within the heater can.
IMPORTANT: It will take a few seconds for the
temperature to stabilise once changes have been
made.
To adjust the shower temperature -
Economy and High settings only
• The water temperature is altered by increasing
or decreasing the flow rate of the water
through the shower via the temperature
control (g.19).
• After obtaining your showering temperature,
the knob can be left as the normal setting
