for later use.
DO NOT take risks with plumbing or electrical
equipment.
Isolate electrical and water supplies before
proceeding with the installation.
The unit must be mounted onto the finished
wall surface (on top of the tiles). Do not tile up
to unit after fixing to wall.
Contact Customer Service (see back page), if
any of the following occur:
If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated.
If the unit shows a distinct change in
performance.
If the shower is frozen.
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
300mm 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.
DO NOT use excessive force when making
connections to the flexible hose or
showerhead, finger tight is sufficient.
All plumbing connections must be completed
before making the electrical connections.
ELECTRICAL
The installation must comply with BS 7671
‘Requirements for electrical installations’ (IEE
wiring regulations), building regulations or any
particular regulations as specified by the local
Electrical Supply Company.
This appliance MUST be earthed.
In accordance with ‘The Plugs and Sockets etc.
(Safety) Regulations 1994’, this appliance is
intended to be permanently connected to the
fixed wiring of the electrical mains system.
Make sure all electrical connections are tight
to prevent overheating.
Fuses do not give personal protection against
electric shock.
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.
Switch off immediately at isolating switch if
water ceases to flow during use.
Other electrical equipment i.e. extractor fans,
pumps must not be connected to the circuits
within the unit.
Switch off at isolating switch when not in use.
This is a safety procedure recommended with
all electrical appliances.
As with all electrical appliances it is
recommended to have the shower and

T90xr pumped electric shower
This book contains all the necessary fitting and
operating instructions for your Triton pumped
electric shower. Take time to read this book
thoroughly and familiarise yourself with all
instructions before installing. Please keep it for
future reference.
The shower installation must be carried out in
the sequence of this instruction book.
Do not attempt any electrical or plumbing work
necessary to install this product unless you
have good practical experience and adequate
understanding of the IEE regulations and water
regulations
Care taken during the installation will provide a
long, trouble-free life from your shower.
Meets with Compliance with European
Community Directives (CE).
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 unit which determines the shower
temperature at any given setting. (The slower
the flow the hotter the water becomes, and
the faster the flow the cooler the water.)
b.
During winter, mains water supply will
be cooler than in summer. Therefore,
the temperature of the shower will vary
between seasons on any one setting of the
temperature control, e.g. if you have chosen
setting number 6 as your preferred shower
temperature in the summer, you will have
to increase that number during winter by
adjusting the temperature control clockwise
(which in effect slows the water flow).
c. If for any reason there is a sudden rise in water
temperature, the unit has thermal cut-out
devices built-in (see items 3 and 4 under ‘Fault
Finding’).
d. Switch off immediately at the isolating switch
if water ceases to flow. Press the Start/Stop
button and contact Customer Service for
advice.
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:
1 The 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.
2 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.
3 The 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.
4 Check 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.
6 A 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.
7 Where shower cubicles are located in any
rooms other than bathrooms, all socket
outlets in those rooms must be protected by
a 30mA RCD.
8 The 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.
9 The 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 the
Water Regulations/Bylaws.
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).
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.
Note: The supply pipe from the cistern should be
on the opposite side to the float operated valve
to prevent air being drawn into the pipe when
the cistern is filling.
If it is intended to operate the shower in
hard water areas (above 200 ppm temporary
hardness) a scale inhibitor should be fitted.
Fig.4 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.
WARNING!
Under no circumstances must this
shower be connected directly to the
mains water supply.

WARNING!
The shower must not be positioned
where it will be subjected to freezing
conditions.
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.5 for 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.
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 soap dish 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.
Allow enough room between the ceiling and the
shower to access the cover top screws.
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. Failure to follow
this procedure may also result in causing 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.
