GENERAL
Isolate the electrical and water supplies before
removing the cover.
Read all of these instructions and retain them
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
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.
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.
To enhance electrical safety 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 other than waste
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
installation checked at least every two years by
a competent electrician to ensure there is no
deterioration due to age and usage.

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.
Temperature/flow rate
The temperature control on the unit can be
adjusted to provide shower temperatures to
meet individual needs.
Note: The maximum flow rate for the given
temperature will be greater in the summer
than in winter because of ambient temperature
variance of the mains water supply.
It is strongly advised to select economy power
during periods of hot weather, otherwise at all
other times, leave the power setting at full to
provide the maximum flow rate.
Safety cut-out
The unit is fitted with a non-resettable over-
temperature 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.

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.

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 with a maximum static pressure
of 1 000kPa (10 bar).
Note: If the stated flow rates are not available,
it may not be possible to achieve optimum
performance from the unit throughout the year.
Under site conditions where the power supply is
below 220 volts and the mains water pressure is
above 5 bar, it is recommended to fit a pressure
reducing valve set at 3.5 bar.
Fig.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.
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.

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 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.
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 can cause the PRD to operate.
Make sure the PRD outlet at the bottom of the
unit is not blocked (fig.7).
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 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.

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 lever is an integral part of the
cover — DO NOT attempt to remove it.
Unscrew the two top and one bottom retaining
screws. There is no need to completely remove
the screws, just enough to lift the cover from the
backplate. To allow access for the pipe and cable
connections, remove the trimplate by lifting it
away from the backplate.
Entry positions for the mains water are from the
top, bottom or back. Cable entry is via the top,
bottom or back.
Note: Deviations from the designated entry
points will invalidate product approvals.
If bottom surface entry is required, then the
necessary hole will need to be cut out in the
thinned section of the trimplate using a junior
hacksaw and file (fig.8).
If bottom or rear entry is chosen, the pipe trim
will need to be fitted in the top entry position on
the backplate (fig.9). The pipe trim is packaged
separately.
If installing a supply pipe from the bottom, the
centre of the inlet valve to the wall surface is
21 mm.
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 over the pipework to make the
nut accessible for future adjustments.
Note: the distance between the centre of the
inlet valve and the wall is 21 mm (fig.10).
To ease the installation of the unit remove the
shaded area shown in fig.11.

Slide the compression nut and olive onto the
unit inlet pipe. Make sure the inlet filter is in
place before attempting to fit onto the elbow
connector (fig.12).
Turn the unit at an angle similar to that shown in
fig.13. This will allow easier access for fitting the
inlet pipe onto the elbow connector.
Fit the unit, taking care to make sure that the
inlet pipe is connected to the elbow. Once the
inlet pipe is located, carefully turn the unit anti-
clockwise until it is level and push gently into
place onto the elbow (fig,14).
After choosing the site for the shower, use the
backplate as a template (fig.15) and mark the
three fixing holes.
Remove the unit. Drill and plug to suit the fixing
screws supplied. (The wall plugs provided are
suitable for most brick walls — use an appropriate
masonry drill. If the wall is plasterboard or soft
building block, you must use suitable wall plugs and
an appropriate drill bit).
Secure the unit in place using the screws
supplied. Do not fully tighten the screws at
this stage, as the fixing holes are elongated for
out of square adjustment after the plumbing
connections has been completed.

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.
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.
Procedure
Turn off the 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
compression fitting. The plastic filter protrudes
from the inlet (fig.16) so make sure it is in
place before connection.
The compression fitting must be pushed fully
home onto the inlet to ensure full engagement.
Note: The inlet fitting is designed to enter a
compression fitting only. DO NOT use push-
fit connectors as full engagement cannot be
guaranteed. DO NOT use excessive force when
making these connections.
IMPORTANT: Before completing the
connection of the water supply to the inlet
of the shower, and in compliance with Water
Regulations, 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.
Make sure the backplate is square on the wall
and tighten the three retaining screws which
hold it to the wall. Check the backplate is not
distorted when screws are fully tightened.
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: Using a suitable sealant,
always seal around the incoming pipework
to prevent water entering the wall.

Fig.17 shows a schematic wiring diagram.
The cable entry points are top, bottom or back.
The cable can be surface clipped, hidden or via
20 mm conduit.
Note: Conduit entry can only be from rear.
SWITCH OFF THE ELECTRICITY SUPPLY AT
THE MAINS.
Route the cable into the shower unit and
connect to the terminal block as follows:
Earth cable to terminal marked
Neutral cable to terminal marked N
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 to supply
power to other equipment i.e. extractor fans,
pumps etc. will invalidate the guarantee.
DO NOT switch on the electricity supply until
the cover has been fitted.
Note: The elements on UK models are to 240V
specifications and will give a lower kW rating if
the voltage supply is below 240V.

WARNING!
Before normal operation of the
shower, it is essential the following
commissioning procedure is completed
correctly.
The first operation of the shower is intended to
flush out any remaining system debris, to make
sure that water is purged through the unit and
that the heater unit contains water before the
elements are switched on.
Refit the trimplate by carefully guiding into the
locating slots in the backplate.
Temporarily fit the cover in order to carry out
the commissioning procedure.
a. Offer the cover to the unit. DO NOT
connect the 14-way ribbon cable at this
stage.
b. Make sure the valve spindle has the ‘flat’
and keyway slot uppermost (12 o’clock
position) as shown in fig.18.
c. Make sure the temperature control lever
is positioned correctly — the lever ‘flat’
inside the cover should be uppermost
(fig.19).
d. Carefully locate the cover tags into the
guide pockets on the backplate and make
sure the wires are not trapped.
e. Guide into position so that the control
spindle locates correctly (the ‘flats’ will
only allow the spindle and lever to fit one
way).
Should any difficulty arise, recheck the points
above.
While applying slight pressure to the front cover,
secure in position with the three retaining screws.
Fit the flexible hose (but without the
showerhead) to the shower outlet making sure
the outlet of the hose is directed to waste. Check
the supplied sealing washer is in place.
Turn on the water supply to the shower at the
isolating stopvalve. Switch on the electricity
supply to the shower at the isolating switch.
Water will start to flow through the unit and
discharge from the flexible hose.

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 a
smooth flow of water is obtained, disconnect the
electricity supply to the shower at the isolating
switch. This will stop the water flow. Unscrew
the cover retaining screws again and lift the
cover from the backplate.
Attached to the control PCB inside the cover
is a 14-way ribbon cable. The ribbon cable
connector must be plugged into the socket
located on the power PCB inside the unit
(fig.20). The connector can only be correctly
plugged in one way because of a location lug on
the plug. The ribbon cable also has a coloured
edge which is on the right-hand side when
correctly fitted to the socket.

Offer the cover to the unit. Carefully locate
the cover tags into the guide pockets on the
backplate and make sure wires are not trapped.
Guide into position so that the control spindle
locates correctly (the ‘flats’ will only allow the
spindle and knob to fit one way). While applying
slight pressure to the front cover, secure in
position with the three retaining screws.
The flexible hose can be left attached to the
shower outlet. Make sure the supplied sealing
washer is fitted.
Once the riser rail kit is installed, the shower is
ready for normal operation.
IMPORTANT: Before finally fitting the
cover, the following steps must be taken:
a. Check all plumbing connections are
watertight.
b. Check terminal block screws are fully
tightened.
c. Make sure the pipe and cable entering
the unit do not prevent the cover
locating correctly to the backplate.
d. Make sure the valve spindle has the
‘flat’ and keyway slot uppermost (12
o’clock position) as shown in fig.18.
e. Make sure the temperature control
lever has the ‘flat’ inside the cover
uppermost (fig.19).

The shower controls are shown in fig.21.
Make sure the water supply is turned fully on.
Switch the electric supply back on at the
isolating switch.
Immediately the start up routine commences
and the four LED’s flash simultaneously three
times (the Care Plus will also emit a single
‘bleep’).
Starting the shower
Press the START/STOP button and water will
begin to flow (the Care Plus will emit a single
‘bleep’). The two power indicators light, to show
the shower is running at full power.
Stopping the shower
Press the START/STOP button (the Care Plus will
emit a single ‘bleep’) and the phased shutdown
will begin. Water continues to flow for a few
seconds, flushing out any remaining hot water.
This guarantees that the next immediate user
does not receive a slug of hot water if standing
under the showerhead when starting the shower.
Using the control buttons
The shower has two control buttons — POWER
and COLD, as shown.
This symbol is for COLD water only.
When pressed, the LED above the button
lights up (the Care Plus will ‘bleep’
once). It will remain in this state until the
power button is pressed.
Note: Adjustment of the temperature control at
this setting has no effect on the force of water
from the showerhead.
This symbol is the POWER button, which
is a toggle switch between full power
and economy power.
Note: The shower automatically starts up on the
full power setting.
Economy is for using less power when the
ambient mains temperature is high during hot
months.
If the shower is on full power and the POWER
button is pressed, one of the LED’s below the
button goes out (the Care Plus will also emit a

single ‘bleep’). During this time, the flow rate
decreases to try to achieve the same temperature
as before.
Note: If the temperature setting was high at full
power, then it will not be possible to obtain the
same temperature as before on the economy
setting. The shower will attempt to provide the
highest temperature at the best flow rate.
Adjust the temperature 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 shower on economy
power during hot months because of flow rate
limitations entering the unit.
If the shower is on economy power or the cold
setting and the power button is pressed, both
LED’s will light up (and the Care Plus will emit
a single ‘bleep’). During this time, the flow
rate increases to achieve the same temperature
as before or to correspond to the current
temperature control position.
It is advisable to select full power at all times,
except during periods of hot weather.
Adjusting the shower temperature
The showering temperature is varied by turning
the temperature control which changes the mix
of hot water coming from the heater can and
the incoming cold water.
On the display circumference are ten marked
outer segments which represent the total
angular movement of the temperature control.
To increase the shower temperature turn the
temperature control clockwise (fig.22). (The
Care Plus will ‘bleep’ three times when an
outlet temperature of 41°C or above has been
reached).
To decrease the shower temperature turn the
temperature control anti-clockwise (fig.23).
After obtaining your preferred showering
temperature the control can be left as the
normal setting.
Setting the adjustable temperature stop
This shower unit is fitted with a temperature
stop. This is factory set to allow the full range
of temperatures to be selected. If required,
Fig.23
Fig.22

T100e thermostatic care & care plus
17
the temperature stop can be adjusted by the
installer to lock at a selected temperature setting,
according to individual needs.
Procedure
With the cover in place, start the shower as
normal. Set the temperature control to the
maximum required temperature. This can
be with the pointer positioned at any point
between 1 and 10 on the front cover markings.
Make a note of your chosen maximum position.
Turn off the shower and isolate the electricity
supply at the mains.
With a suitable screwdriver, unscrew the three
cover retaining screws and lift the cover from the
backplate.
Inside the cover is the temperature control
(fig.24). With a suitable screwdriver, remove
the centre screw from the adjustable stop.
IMPORTANT: Take care not to disturb the
temperature lever on the front cover from the
position selected.
Lift out the adjustable stop and reposition it at
position ‘A’ (fig.25). Screw the stop back into
position.
IMPORTANT: DO NOT rotate the valve
spindle when the cover is removed as this will
alter your selected temperature.
Offer the cover to the unit and carefully locate
the cover tags into the guide pockets, and the
control spindle into the cover correctly. While
applying slight pressure to the cover, secure in
place with the three retaining screws.
Switch on the electricity supply and start the
shower.
Check that the temperature control lever locks
at a position which provides a satisfactory
showering temperature for all users.
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 temperature
and the water reaching the stable selected
temperature.

Low pressure
indicator
Low pressure
When the low pressure indicator (fig.26)
flashes steadily (the Care Plus will also ‘bleep’
intermittently) it means the water pressure has
fallen below the minimum pressure required
for correct operation of the shower, resulting in
the low pressure switch operating. This switches
off power to the heating elements preventing
any maintained temperature rises. Water will no
longer flow until the unit has been reset.
Press the START/STOP button once to reset the
shower. The low pressure light will go out and
the unit will now be ready for normal operation.
Once normal water pressure is restored, the unit
can be restarted by pressing the START/STOP
button.
Phased shutdown
In use, when the START/STOP button is pressed,
power is switched off to the elements and the
power indicator will extinguish. Water continues
to flow for a few seconds, flushing out any
remaining hot water. This makes sure that the
next immediate user will not receive a slug of
hot water if standing under the showerhead
when starting the shower.
Safety cut-out
The shower is fitted with a 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
find out the nature of the fault and replace the
safety device, once the unit has been repaired.
Note: In normal use, it is normal to leave the
water supply permanently on to the shower unit,
but as with most electrical appliances, the unit
should be switched off at the isolating switch
when not in use.
