1 PLUMBING NOTES
1.1 All installations must comply with Water
Regulations or Water Byelaws.
1.2 Supply pipes must be flushed to clear
debris before connecting the shower unit.
1.3 DO NOT connect the shower unit to the
mains cold water supply as it would
damage the unit and also, the installation
would be in breach of Water Regulations.
1.4 DO NOT use excessive force when making
connections to the flexible hose or
sprayhead – finger tight is sufficient.
1.5 ALL plumbing connections are to be
completed and water supplies turned on
BEFORE switching on the electricity supply.
The shower must not be operated dry
without water.
1.6 DO NOT solder pipes or fittings within
300mm of the shower appliance, as heat
transfer can damage components.
1.7 When installed, the top of the shower unit
must be at least 75mm lower than the base
of the cold water storage cistern to prevent
the pump being run dry without water.
1.8 A dedicated cold water supply must be
taken directly from the cold water cistern
to the shower. This draw-off must be on
the opposite side of the cistern to the float
operated valve to reduce the risk of air
entering the unit.
1.9 The action of the pump is to increase the
flow rate. If the supply pipework cannot
handle the resulting flow rate then:
1.9.1 The anticipated flow rate may not
be achieved.
1.9.2 Air may be drawn into the hot
supply from the vent pipe causing
spluttering and temperature fluctuations at
the sprayhead.
1.10 A high level hot feed pipe run will result in
air locking and must be avoided.
1.11 Fullway isolating valves MUST be fitted on
the hot and cold water supplies to the
shower as an independent means of
isolating the water supplies should
maintenance or servicing be necessary. DO
NOT use stop taps or ball-o-fix type valves
which restrict flow.
2 ELECTRICAL NOTES
2.1 The installation must comply with BS 7671
‘Requirements for electrical installations’
(IEE wiring regulations). Make sure the
incoming hot and cold water supplies to
the shower are adequately earth bonded.
2.2 DO NOT turn on the electrical supply until
the plumbing connections have been
completed. Only then can the electricity be
switched on in order to power the solenoid
to turn water on to the shower when
commissioning. The shower must not be
operated dry without water.
2.3 The mains supply must be 230/240V, at
50Hz, connected to the unit via a double
pole switched 3 Amp fused connection
unit (not supplied) with a minimum 3mm
contact separation gap in each pole.
2.4 In accordance with ‘The Plugs and Sockets
etc. (Safety) Regulations 1994’, this unit is
intended to be permanently connected to
the fixed electrical wiring of the mains
system.
2.5 Fuses do not give personal protection
against electric shock.
2.6 It is strongly recommended to fit a 30mA
residual current device (RCD). This may be
part of the consumer unit or a separate
unit.

INTRODUCTION
This book contains all the necessary fitting and
operating instructions for your Triton Power
Shower. Please read them carefully.
The shower installation must be carried out by
suitably competent person and in sequence of
this instruction book.
Care taken during the installation will ensure a
long and trouble free life from your shower
IMPORTANT: All plumbing connections must
be completed BEFORE making the electrical
connections.
Please read through the whole of this book
before beginning your installation.
IMPORTANT: The fittings on the pipe inlet
elbows are of the push-in type. The pipework
must be cut with a pipe cutter and all burrs
and rough edges removed from the end of
the tube. The fittings can be used with
copper and plastic pipe.
Where chrome plated pipe is used, remove
the first 25mm of plating.
Note: The pump inside this product is rated 15
minutes on / 45 minutes off duty cycle.
SAFETY WARNINGS
a. Do not insert fingers into the push-in inlet
fittings. Doing so could cause injury.
b. Under no circumstances must this
product be connected to mains cold or
hot water supplies. Failure to comply will
invalidate the guarantee.
c. The shower MUST NOT be used if suspected
of being frozen.
d. The outlet of this appliance must not be
connected to any form of tap or fitting not
recommended by the manufacturer.
e. The sprayhead cartridge must be cleaned
regularly to remove scale and debris.
f. This appliance must be earthed.
g. Switch off immediately at the isolating
switch if water ceases to flow during use.
h. Do not operate the shower outside the
guidelines laid out in ‘site requirements’.
In the interest of electrical safety a 30mA
residual current device (RCD) should be
installed in all UK 230V electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details and part
numbers.
Due to continuous improvement and updating,

Hot water temperature
Maximum temperature 65°C.
BS 6700 recommends that the temperature of
stored water should never exceed 65°C. A stored
water temperature of 60°C is considered
sufficient to meet all normal requirements and
will minimise the effects of scale in hard water
areas.
Temperature control
To obtain the maximum performance, this unit
should be installed, operated and maintained as
instructed in this book. The full performance
specification as below for the unit is achieved
with a blend set between 35°C – 40°C and
supplies of 15°C cold and 65°C hot with
nominally equal pressures.
1) The blended water temperature is
maintained within 2°C with a 10°C change in
the hot and cold water supply.
2) The sensor effects a shut down to seepage in
about 2 seconds if the cold supply fails.
3) Shut down to seepage is achieved even if the
hot supply is only 12°C above the blend
temperature.
4) The blended water temperature is
maintained within 1°C when the pressure
between inlet and outlet is halved (defined as
a pressure loss ratio of 2:1) on either the hot
or cold side.
Maximum static inlet pressures
1 bar or 10m (supplies must be gravity fed at
nominally equal pressures).
Minimum static inlet pressure
0.0075 bar or 75mm (required to prime the
integral centrifugal pump).

tee.
Fig.3 illustrates all the incorrect connections
that must be avoided.
All pipework to the shower unit must be routed
where it remains below the level of water in the
cistern. In the case of horizontal sections of
pipework in lofts, it may be necessary to fit
automatic air vents at high points on the
supplies to remove the possibility of air locks.
For the operation of the shower only, it is
recommended that the cold water storage
cistern is capable of holding at least 114 litres
(25 gallons). Where other hot and cold outlets
are likely to be in use simultaneously, the storage
capacity should be increased to 228 litres (50
gallons) in accordance with BS 6700.

SITE REQUIREMENTS
Water
The installation must be in accordance with
Water Regulations/Byelaws and BS 6700.
For correct operation of this shower unit, both
hot and cold water supplies to the appliance
must be gravity fed, at nominally equal
pressures, from a cold water storage cistern and
a hot water storage cylinder.
The water circuit should be installed so that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on the
premises.
Fig.2 shows a recommended installation where
the hot water supply for the shower is made via
a tee connection on the underside of the
horizontal section of pipework from the cylinder.
Alternatively, the connection can be taken from
the hot supply pipe to other outlets as long as it

unless there is a guaranteed 114 litre cold supply
to the cylinder as the shower can deliver up to
14 litres per minute. It is advisable to check that
the infill rate from the float operated valve meets
the output requirements..
It is recommended that there is a minimum of
approximately 114 litres (25 gallons) of hot
water storage per appliance.
The shower MUST NOT be connected to
the mains cold water supply.
DO NOT use jointing compounds.

5The unit must be mounted onto the finished
wall surface (on top of tiles).
DO NOT tile up to the unit after fixing to
the wall.
6If installing with rear inlet supplies, it is
recommended the supply pipework is sealed
to the wall so as to prevent water from
leaking back into the wall.
7In solid wall installations, the supply
pipework should be housed within ducting
in order to allow some free lateral
movement when making connections and
to ensure compliance with requirements of
accessibility of pipes and pipe fittings.

SITING OF THE SHOWER
IMPORTANT: If fitting to 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 vertically where it will NOT be
in direct contact with water from the sprayhead.
Note: Allow sufficient room between the ceiling
and the shower unit to access the top cover
screw.
Position the shower and sprayhead on the wall
so that all controls can be comfortably reached
when using the shower.
The sprayhead and riser rail can be positioned
either side of the shower unit.
Note: Water Regulations require the sprayhead
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’. The use of the supplied soap dish will
in most cases meet this requirement, but if the
sprayhead can be placed within a bath, basin or
shower tray, then a device must be fitted to
prevent back-flow.

REMOVING THE COVER
To remove the cover, first pull off the cover trim
from the temperature control (fig.6) and undo
the retaining screw. Pull off the temperature
control.
This will reveal the maximum temperature stop
(fig.7). This should be left in position.
Note: If adjustment of the maximum
temperature stop is required, refer to section
’Adjusting the maximum temperature stop’.
Remove the two cover fixing screws – top and
bottom (fig.8).
Carefully lift the cover away from the backplate.
Lay aside the cover and screws until the unit is
fully installed.
Note: When removing the cover for future
maintenance purposes, be aware of the lead
connected to the PCB unit. Carefully pull off the
lead from the PCB.
DO NOT let the cover dangle by the lead.
PLUMBING CONNECTIONS
Plumbing to be carried out before wiring
Note: The outlet of the shower must not be
connected to anything other than the hose and
sprayhead supplied.
DO NOT use jointing compounds on any pipe
fittings for the installation.
When connecting pipework avoid using tight
90° elbows. Swept or formed bends will give
optimum performance.
Isolate the mains water supply to the cold water
cistern. Drain the hot and cold pipes by opening
all taps.
The hot water supply can be taken from the hot
supply pipe from the cylinder. Make sure that it
is the first draw-off below the ventilation pipe
tee in order to minimise the effects of water
draw-off elsewhere in the house (see fig.2).
Note: There must not be any other draw-offs
between the take-off point and the shower.
A dedicated cold water supply must be taken
directly from the cold water cistern to the
shower. This draw-off must be positioned 25mm
below the cold feed connection to the hot water

cylinder on the opposite side of the cistern to
the float operated valve (see fig.2). This
minimises air ingress into the pipework.
Plumbing options other than those outlined in
these fitting instructions could impair the
performance. For example, if hot and cold
connections are made after draw-off points to
other outlets, (eg. washing machine, taps, etc.)
it could result in unstable flows and
temperatures should other appliances operate at
the same time.
Run the hot and cold pipework to the shower
position, making sure that the pipework does
not rise above the level of water in the cold
cistern at any point to avoid air locks. Under
normal site conditions 15mm pipework will be
adequate.
Decide the position of the shower. Cut the
pipework to the dimensions relevant to the
chosen direction of water entry into the shower.
IMPORTANT: For rear entry only, the
supplied elbows must be used. For ease of
installation, the backplate area adjacent to
the top pipe inlet must be cut out, including
the top left wall fixing hole.
When fitting the elbows to incoming pipework,
ensure the elbow collets are fully engaged with
the pipe.
Dimensions are shown in fig.9 and fig.10.
Note: The pipe inlets are marked for hot and
cold connections – left-hand side for hot inlet on
bottom entry (fig.11), but right-hand side for
hot inlet on top or rear entry (fig.12).
IMPORTANT: The fittings on the inlet elbows
are the push-in type. The pipework must be
cut with a pipe cutter and all burrs and rough
edges removed from the end of the tube. The
fittings can be used with copper and plastic
pipe.
If using chrome plated copper pipe, remove
the first 25mm of plating completely from the
connecting surfaces. If not completely removed
then the collet will not grip the pipe and
under pressure the pipe may be forced out.
Note: Pipework must be clipped or fixed to the
wall so that it cannot be moved or removed
without the aid of a tool.

Note: The pipe inlets contain filters. These
should be periodically removed and cleaned in
order to maintain the performance of the
shower. See section ‘cleaning’ on how to access
the filters.
IMPORTANT: The inlets contain check valves,
so before completing the connection of the
water supplies to the shower flush out the
pipework to remove all swarf and system
debris that may cause damage to internal
parts. This can be achieved by connecting a
hose to the pipework and turning on the
water supplies long enough to clear the
debris to waste.
IMPORTANT: Two factory fitted blanking
plugs are fitted to the top pipe inlets. These
should be left in position if bottom pipe entry
is required.
For top or rear pipe entry, the two plugs
MUST be removed and refitted into the
bottom pipe inlets. Failure to fit the blanking
plugs will result in the unit working
erratically.
Insert the pipe removal tool supplied between
the flange of the plug and the grey collet and
lever the plug outward (fig.13). Whilst holding
back on the collet, pull out each plug by hand.
When refitting the plugs in the bottom pipe
inlets, make sure they are pushed fully home.
Note: The unit is supplied with a splash guard
(fig.14) to prevent water ingress when top
entry pipework is used. If fitting top entry
pipework, make sure the splash guard is
correctly fitted (fig.14) before replacing the
cover.

FITTING THE SHOWER TO THE WALL
IMPORTANT: Prior to fitting the shower,
ensure plumbing is flushed out, removing all
debris, flux etc.
For top pipe entry or top cable entry, remove
the relevant cut-outs by either breaking out or
by using a knife or junior hacksaw (fig.15).
If top entry for both pipe and cable is required,
then additionally remove the shaded area
(fig.15) by using a knife or junior hacksaw.
For bottom pipe entry, remove the cut-out and
break off the two circular parts (fig.16).
Replace the cut-out.
For rear pipe entry only, the supplied elbows
must be used with the necessary portion of
backplate cut away as shown in fig.9.
It will be necessary if rear cable entry is required,
for conduit or other routing of the electrical
cable to be completed before fixing the shower
to the wall.
Offer the backplate unit up to the completed
pipework and manoeuvre so that the end of the
pipes enter fully into the inlet fittings.
Mark positions for wall fixing holes using
backplate as template (fig.17). Note that four
fixing holes are provided but using only two
should be adequate for most site conditions.
Using the pipe removal tool supplied, push back
and hold the collets from the pipework (fig.18)
to disengage the pipework from the inlet elbows.
Remove unit from the wall.
Drill and plug the fixing holes using the screws
and plugs supplied. (The wallplugs 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 special wallplugs
and an appropriate drill bit).
Note: If fitting rising supplies to the unit, ensure
debris does not enter the pipes when drilling the
wall.
Offer the backplate unit up to the completed
pipework and manoeuvre so that the end of the
pipes enter fully into the inlet fittings.
Check the backplate is square and the fixing
holes are aligned (fig.17).
Secure to the wall with fixing screws supplied.

ELECTRICAL CONNECTIONS
The supply cable must conform to relevant
tables in current IEE regulations. In most cases
1mm2twin and earth will be adequate.
The electrical rating of the shower is on the
rating label within the unit.
SWITCH OFF THE ELECTRICITY SUPPLY AT THE
MAINS.
Cable entry points are shown in fig.1. Conduit
entry can only be from the rear.
Route the cable into the shower, taking care to
avoid the area of the wall fixings and connect to
the terminal block (fig.19) as follows:
Earth cable to terminal marked E
Neutral cable to terminal marked N
Live cable to terminal marked L
IMPORTANT: Fully tighten the terminal block
screws and check that no cable insulation is
trapped under the screws.
Note: The supply cable earth conductor must
be sleeved.
The earth continuity conductor of the electrical
installation must be effectively connected
electrically to all exposed metal parts of other
appliances and services in the room in which the
shower is to be installed, to conform to current
IEE regulations.
Note: Fuses do not ensure user protection
against electric shock. In the interest of electrical
safety, all mains electric and pumped showers
should be fitted with a 30mA residual current
device (RCD). This may be part of the consumer
unit or a separate unit.
DO NOT switch on the electricity supply
until the water has been turned on to the
unit and connections have been tested for
leaks.

COMMISSIONING
IMPORTANT: The cover may be left off
initially only for commissioning.
The first operation of the shower is intended to
flush out any remaining system debris and to
ensure water is purged through the unit. This
operation must be carried out with the flexible
hose screwed to the shower outlet but without
the sprayhead attached.
Make sure the outlet of the flexible hose is
directed to waste.
Make sure the isolating valves controlling the
water supply to the unit are fully open.
Note: There is no need to fit the cover at this
stage but be aware of live parts when the
electricity is switched on temporarily.
Fit the temperature control onto the spindle
(fig.20).
On the PCB, position the commissioning link on
the middle two pins (fig.21).
Switch on electric supply at isolating switch.
Water will begin to flow under gravity pressure.
In order to dispel air and to prime both supplies
to the shower unit, turn the temperature control
several times within its rotational limits. ONCE
RESISTANCE IS FELT, DO NOT FORCE THE
CONTROL FURTHER.

Note: The temperature control rotates less than
one complete turn (fig.22) – from 3 o’ clock
(cold) anti-clockwise to 6 o’ clock position (hot)
and vice versa. DO NOT force it beyond these
limits.
To stop the water flow, switch off the electricity
supply at the isolating switch.
Check for leaks in the pipework and remedy if
necessary. If rear entry has been used then seal
around pipes with mastic to prevent the
possibility of water entering the wall cavity. DO
NOT use plaster as this could cause difficulties if
maintenance is required at a later date.
Setup procedure
MAKE SURE THE ELECTRICITY TO THE UNIT IS
SWITCHED OFF.
Pull off the temperature control.
Remove the commissioning link from the PCB
(fig.23) and store safely for future use.
Offer the cover to the unit. Make sure the
Start/Stop button is in the ‘off’ position - flush
with the cover. Attached to the flow control
potentiometer inside the cover is a 4-wire lead.
Fit the connector on the end of this lead to the 4
pins on the PCB (fig.24) – it can fit either way.
Replacing the cover
Check the valve spindle is correctly positioned
before refitting the cover. See the section
‘Temperature control spindle setting’ for further
details.
Fit the cover, ensuring the connector is fitted to
the PCB and the wires are clear of the cover.
Secure with the top and bottom fixing screws
(fig.8).

FITTING THE RISER RAIL
Decide the position for the rail on the wall
within the shower area. Proceed as follows:
Fit the sprayhead holder onto the riser rail. The
correct orientation of the holder is when the
sprayhead holder is sloping DOWN (fig.27).
To fit the sprayhead holder onto the riser rail
unit, press and hold the button on the
underneath of the sprayhead holder to release
the locking mechanism, then slide onto the rail.
Slide the supplied soap dish onto the riser rail
below the sprayhead holder (fig.28).
Slide the top and bottom finishing trims onto
the riser rail (fig.29).
Push the two fixing brackets into the ends of the
riser rail (fig.30).
Offer the rail assembly to the wall (fig.31).
Using the brackets as templates, mark two upper
holes and two lower holes. Note there are four
provisions for screws per bracket – select the two
most suitable for your requirements. Make sure
the rail is aligned vertically.
Drill and plug the wall. (The wallplugs provided
are suitable for most brick walls – use an
appropriate masonry drill, but if the wall is
plasterboard or a soft building block, use special
wallplugs and an appropriate drill bit).
Screw to the wall with the fixing screws
supplied.
Slide the finishing trims onto the brackets. Make
sure the lug on each rail bracket end engages
into the slot on the fatter end of each trim
before push fitting the thinner ends in place
(fig.32).
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.

Adjusting the sprayhead holder
To adjust the height, press the button
underneath the holder to release the locking
mechanism (fig.33). Still pressing the button,
move the holder up or down to suit user’s
requirement.
Fitting the hose and sprayhead
Feed the flexible hose through the soap dish
aperture (fig.34) so the dish acts as a retaining
ring (Water Regulations).
Screw the flexible hose to the shower outlet and
sprayhead, checking the supplied washers are in
place at both ends of the flexible hose (fig.35).
Place the sprayhead into the holder and check
that it fits correctly (fig.36).
Note: The holder is slightly tapered and the
sprayhead and hose will only fit from one
direction.
IMPORTANT: It is the conical end of the hose
which grips into the holder. The sprayhead
will not fit in the holder without the hose
attached. At this stage, disconnect the
sprayhead and lay aside until the shower unit
has been commissioned.

OPERATING THE SHOWER
Make sure all plumbing and electrical supplies
are connected and switched on.
To start the shower, press the Start/Stop button
(fig.37).
Adjust the flow control (fig.38) until the flow
rate is satisfactory.
For maximum flow, turn the flow control fully
clockwise. For minimum flow, rotate the flow
control fully anti-clockwise.
To adjust the water temperature, rotate the
temperature control (fig.39). The temperature
is numbered for ease of use, ranging from ‘1’ –
fully cold to ‘9’ – fully hot.
Once the preferred temperature is reached, no
further adjustment is required, providing the hot
and cold water supplies remain constant.
To stop the shower, press the Start/Stop button
once more. This stops the pump and water flow.
Unless the shower is to be used again
immediately, the shower should also be
switched off at the electricity isolating switch.
As a safety feature, the temperature control has
a built-in stop to prevent you accidentally
exceeding your highest desired temperature. If
adjustment is required see section ‘Adjusting the
maximum temperature stop’.
To override this stop, press the button (fig.40)
while the control is up against the stop and turn
the control anti-clockwise to the higher settings
(pressing the button before the stop will not
operate the override mechanism even if the
control is turned with the button depressed).
To return to the normal temperature range just
turn the temperature control clockwise until it is
past the maximum temperature stop. Make sure
that the temperature control is in the normal
temperature range when the shower is switched
off. The stop comes in a factory set position
based on 65°C stored hot water temperature.
CAUTION: It is recommended that persons who
may have difficulty understanding or operating
the shower controls should not be left
unattended whilst showering. Special
consideration should be given to young children
and the less able bodied.

ADJUSTING THE MAXIMUM
TEMPERATURE STOP
As a safety feature the shower has a built-in
maximum temperature stop to prevent you
accidentally exceeding your highest desired
temperature. This is set in the factory to provide
a maximum temperature based on the hot and
cold water supplies being 65°C and 15°C
respectively.
Procedure
Rotate the temperature control to setting ’5’ on
the temperature scale.
Remove the cover trim to gain access to the
retaining screw. Unscrew the retaining screw
and pull off the temperature control (fig.41).
Carefully pull off the maximum temperature
stop mechanism.
To increase the temperature stop setting,
reposition the mechanism anti-clockwise within
the arc of the grooves (fig.42).
To decrease the temperature stop setting,
reposition the mechanism clockwise within the
arc of the grooves (fig.42).
Replace the temperature control by push fitting
onto the spindle, making sure the pointer relates
to the ‘5’ on the temperature scale.
Refit the retaining screw and push the cover trim
into place.
IMPORTANT: Only adjust the maximum
temperature stop when the hot water is at its
usual storage temperature.
