WARNING!
During periods of high ambient water
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 (fifteen metres for the 10.5kW rated
shower). It must be an independent supply to
the shower only.

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.

Important: The unit must be mounted
on a flat surface which covers the full width
and length of the backplate, otherwise
difficulty may arise when fitting the cover
and subsequent operation of the unit may
be impaired.
Liquid Crystal Display
This shower unit has a LCD which has an
optimum viewing angle that is slightly below eye
level. Therefore position the unit so the display
is at nose level. For multiple users of varying
heights, an optimum shower height must be
arrived at.
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.
7
Thermostatic electric shower
Make sure the PRD outlet at the bottom of the
unit is not blocked (fig.7).
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.

Note: The control knob 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 to the pipe and cable
connections remove the trimplate by lifting 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.
21mm
Note: Deviations from the designated entry
points will invalidate product approvals.
Fig.11
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).
If installing a supply pipe from the rear or
bottom, 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. This area must be left clear
when plastering over the pipework in order to
make the nut accessible for future adjustments.
After choosing the site for the shower, use the
backplate as a template and mark the three wall
fixing holes (fig.11).
Drill and plug the wall.
(An appropriate drill bit should be used. If the
wall is brick, plasterboard or a soft building block,
appropriate wall plugs and screws should be fitted).
Screw the top left-hand fixing screw into
position leaving the base of the screw head
protruding 6 mm out from the wall.
Hook the backplate over this screw, then fit the
other two fixing screws into position.
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
connections have been completed.

warning!
The outlet of the shower acts as a
vent and must not be connected to
anything other than the hose and
showerhead supplied.
Note: An additional stopvalve (complying with
Water Bylaws/Regulations) must be fitted in
the mains water supply to the shower as an
independent means of isolating the water in
order to carry out maintenance or servicing.
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. To do this,
connect a hose to the pipework and turn on
the mains water supply long enough to clear
the debris to waste.
Procedure
Turn off the water supply either at the mains
stopvalve or the isolating stopvalve. Connect
the mains water supply to the inlet (fig.12) of
the shower via 15 mm copper, stainless steel
or plastic pipe using a 15 mm x 15 mm brass
compression fitting. The plastic filter protrudes
from the inlet so check it is in place before
connection.
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.
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.
IMPORTANT: Using a suitable sealant, always
seal around the incoming pipework to
prevent water entering the wall.
Note: At this stage no water can flow through
the unit.

Thermostatic electric shower
WARNING!
Before normal operation of the
shower, it is essential the following
commissioning procedure is completed
correctly.
Fig.14
COMMISSIONING
Commissioning
The first operation of the shower is intended to
flush out any remaining system debris and to
make sure water is purged through the unit so
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.
Valve
spindle
At this stage, the cover is temporarily fitted 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).
See fig.14.
Fig.15
c. Make sure the temperature control knob
on the cover has ‘TRITON’ horizontal with
the blue/red graphics at the top – the knob
‘flat’ inside the cover should be uppermost
(fig.15).
d. Carefully locate the cover tags into the guide
pockets on the backplate and check the wires
are not trapped.
e. Guide into position so that the control
spindle locates correctly (the ‘flats’ only allow
the spindle and knob only 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, without the showerhead, to
the shower outlet, with the outlet of the hose
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.
12
Thermostatic electric shower
Unscrew the cover retaining screws again and lift
the cover from the backplate.

COVER
Replacing theTHE
cover
Important: Before finally fitting the cover,
the following steps must be taken:
a. Check all plumbing connections are water
tight.
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).
e. Make sure the temperature control knob
on the cover has ‘TRITON’ horizontal
with the blue/red graphics at the top
(the knob ‘flat’ inside the cover should be
uppermost).
Offer the cover to the unit. Carefully locate
the cover tags into the guide pockets on the
backplate and check the wires are not trapped.
Guide into position so that the control spindle
locates correctly (the ‘flats’ only allow the spindle
and knob will only 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.

Control buttons
Fig.21
Apart from the Start/Stop button, there are
two other control buttons – power and cold.
The button marked
is for cold water only.
When pressed the current display is replaced
by ‘CLD’ (fig.23). It remains in this state until
the power button is pressed. Adjusting the
temperature control at this setting has no effect
on the force of the water from the showerhead.
The button marked
is the power button
which is a toggle switch between full power and
economy power.
Fig.22
Economy is for using less power when the
ambient mains water temperature is high during
hot months.
If the shower is on full power and the power
button is pressed, the current display is replaced
by ‘ECO’ for five seconds (fig.24). During this
time, the flow rate decreases to try to achieve
the same temperature as before.
Fig.23
Note: If the setting was high at full power,
then it will not be possible to obtain the same
temperature on economy power. The shower
will try to provide the highest temperature at the
best flow rate.
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.
Fig.24
Full is the maximum power setting which allows
the highest flow achievable for your preferred
temperature.
If the shower is on economy power or the
cold setting and the power button is pressed,
the current display is replaced by ‘FUL’ for five
seconds (fig.25). During this time the flow
rate increases to achieve the same temperature
as before or to correspond to the current
temperature control position.
Fig.25
It is advisable to leave the power setting at full at
all times, except during periods of hot weather.
15
Thermostatic electric shower

Fig.27
To adjust 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 eleven outer segments which
represent the total angular movement of the
temperature control. Rotating the temperature
control causes inner segments to fill, indicating
the actual position of the control relative to its
minimum and maximum limits.
Minimum temperature (fig.26) position (one
inner segment full that corresponds to the
control position).
Maximum temperature (fig.27) position (all
inner segments full that corresponds to the
control position).
Fig.28
To decrease the shower temperature
Turn the temperature control anti-clockwise; the
current temperature display is replaced by two
flashing ‘down arrows‘ (fig.28). Five seconds
later the display shows the revised temperature.
To increase the shower temperature
Fig.29
Turn the temperature control clockwise; the
current temperature display is replaced by two
flashing ‘up arrows‘ (fig.29). A few seconds
later the display shows the revised temperature.
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.

Fig.30
Clean showerhead
After a preset number of Start/Stop button
operations (nominally 75), the start up routine
acts as normal but instead of a blue ‘OK’ the
display backlight turns red and a flashing ‘CS’
alternating with a flashing ‘showerhead symbol’
and ‘CLEAN’ appear (fig.30).
This is a reminder to clean the showerhead. It
does not indicate a defect to the shower.
Fig.31
To remove the red ‘CS’ from the display, press
the power and cold buttons simultaneously for
three seconds. Alternatively you can choose
not to remove the flashing indication and carry
on by pressing the Start/Stop button and
showering as normal, but the ‘symbol’ and
‘CLEAN’ will continue to flash at the side of the
°C figure for a further five shower operations
after which time it will stop (whether you clean
the showerhead or not). The shower will then
reset automatically for a further preset number
of shower operations before flashing the
reminder again.
Low pressure
When the display backlight turns red and
‘LP’ and ’low pressure’ flash alternately, it
means the water pressure has fallen below the
minimum required for correct operation of the
shower (fig.31). This causes the low pressure
switch to operate and this turns 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 shower will shut down and then
begin its start up routine.
If there is still not enough pressure for correct
operation the ‘low pressure’ display will flash
once more and the shower will require resetting
again.
If there is enough pressure the display will
change to show ‘ok’ in a blue backlight and the
shower will run as normal.
17
Thermostatic electric shower
Phased shutdown
Fig.32
In use, when the Start/Stop button is pressed,
power is switched off to the elements and the
power indicator will extinguish. The display
will change to a flashing ‘SD’. Water continues
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.
Safety cut-out
WARNING!
After any servicing of mains water
supply, always make sure the unit is
started on COLD in order to purge any
air in the pipework.
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
determine the nature of the fault and replace the
safety device, once the unit has been repaired.
Changing the fascia
This shower unit has the facility for the coloured
fascia to be simply changed for another colour of
your choice. The coloured options are available
as low cost accessories and are listed in the ‘parts
list’ section at the rear of this booklet.
The top of the fascia has a recessed cutaway.
With your finger, just press down in the cutaway
and pull away (fig.32). To replace the fascia,
position the lower end into the recess of the
cover and push fit the top into position.
Note: In normal use, it is in order to leave the
water supply permanently on to the shower
unit, but as with most electrical appliances,
the unit must be switched off at the
isolating switch when not in use.

CLEANING
Cleaning
WARNING!
Before cleaning, turn off the unit at the isolation
switch to avoid the shower being accidentally
switched on.
Do not use abrasive or aggressive
cleaning products when cleaning the
shower as they may damage the unit.
Triton recommends 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 finish and invalidate your guarantee.
It is important to keep the showerhead
clean to maintain the performance
of the shower. The hardness of the water
will determine the frequency of cleaning. For
example, if the shower is used every day in a
very hard water area, it may be necessary to
clean the showerhead on a weekly basis.
