INTRODUCTION
SAFETY WARNINGS
This book contains all the necessary fitting and
operating instructions for your Triton Severn or
Thames concentric mixer shower. Please read
them carefully. Read through the whole of this
book before beginning your installation.
The shower installation must be carried out by a
suitably competent person and in sequence of
this instruction book.
a
Layout and sizing of pipework must be such
that when other services are used, pressures
at the shower control inlets do not fall
below the recommended minimum.
b
DO NOT choose a position where the
shower could become frozen.
c
DO NOT connect this mixer shower to any
form of tap or fitting not recommended by
the manufacturer.
d
The sprayhead must be regularly cleaned to
remove scale and debris.
e
Conveniently situated isolating valves in
each inlet supply must be fitted as an
independent method of isolating the
shower should maintenance or servicing be
necessary.
f
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, please contact Customer
Service.
g
Do not operate the shower outside the
guidelines as laid out in ‘site requirements’.
Care taken during the installation will ensure a
long and trouble free life from your shower.
For optimum performance within the specified
running pressure range a minimum flow of
8 litres per minute should be available to both
inlets.
The mixer shower MUST NOT be subjected to
water temperatures above 80°C. This mixer
shower is designed for use with traditional low
pressure ‘gravity’ water systems, using a cold
water cistern and hot water cylinder as well as
for the higher pressure systems found in the
U.K. up to a maximum of 5 bar running
pressure.
Important: When installing this mixer with
a combi boiler or multipoint water heaters,
the supplied flow limiters must be installed
in the inlet elbows.
This mixer shower is suitable for fully
modulating type combination boilers and multipoint hot water heaters. Also suitable for
thermal storage, unvented systems and
pumped gravity systems.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details
and part numbers.
Due to continuous improvement and updating,
specification may be altered without prior notice.
Important: Before installing with a gas
instantaneous water heater, ensure it is
capable of delivering hot water at a
minimum switch-on flow rate of 3 litres per
minute. At flow rates between 3 and 8 litres
per minute, the appliance must be capable of
raising the water temperature to a minimum
of 52°C. Water temperature at the mixer
inlet must remain relatively constant when
flowrate adjustments are made (refer to the
water heater operating manual to confirm
compatibility with this mixer shower).
To ensure the product suitability for
commercial and multiple installations, please
contact Triton’s specification advisory service
prior to installation.
Telephone: (024) 7632 5491

SITE REQUIREMENTS
Water temperature requirements
The installation must be in accordance with
Water Regulations and Byelaws.
Maximum hot water temperature = 80°C
Running water pressure:
Gravity fed – 0.1
1.0
Mains fed – 1.0
5.0
Minimum hot water temperature = 52°C

Recommended maximum = 65°C
min.
max.
min.
max.
Maximum cold water temperature = 20°C
BS6700 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.
Maximum static water pressure:
Gravity and mains – 10 bar
DO NOT connect the mixer shower to a gravity
hot supply and a mains cold supply (or vice
versa).
Temperature adjustment range
The mixed water temperature can be adjusted
from cold through to a top limit which must be
pre-set during installation with full anti-scald
protection throughout the range (35°C to
40°C) providing the hot water temperature at
the inlet remains 10°C above the outlet
temperature.
For optimum performance within the specified
running pressure range a minimum flow of
eight litres per minute should be available to
both inlets.
While the mixer shower is operational (open
outlet), inlet pressures must not be capable of
exceeding 7 bar. For effective operation of the
internal seals, the maximum static pressure
must not be exceeded.
NOTE: On sites where the running pressure is
above 5 bar, the use of a suitably sized pressure
reducing valve fitted in the cold mains supply
pipework can provide nominally equal pressures
at the mixer shower.
The pipework should be installed such that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on
the premises.
NOTE: Where thermal store systems and
instantaneous gas water heaters are used, if
excessive draw offs take place the boiler may
not be able to maintain an adequate output
temperature. This could result in the shower
temperature becoming noticeably cooler.

Instantaneous Gas Water Heaters
In order to ensure the optimum performance
from the shower when connected to an
instantaneous water heater, the appliance must
be capable of raising the temperature of the
incoming water to a minimum of 52°C (125°F)
and delivering a flow rate of not less than eight
litres per minute.
With the flow limiters fitted and when the
system is in use, the on/off flow control should
be turned fully anti-clockwise to full flow
setting.

hollow wall structure.
Face plate
If using the fixing bracket in a solid wall
(fig.12), ensure the available building in depth
is at least 55mm measured from the face of the
wall upon which the mounting bracket is
screwed.
SOLID WALL, HOLLOW WALL AND PANEL
MOUNTING
Fig.13
The building in depth for the fixing bracket is
typically 55mm from plaster finish but this is
dependant upon tile and adhesive thicknesses.
Decide upon the shower position and
determine whether the hot and cold water
supplies will enter from the top (falling),
bottom (rising) or rear.
NOTE: For the rear entry supplies, in order to
access the inlet elbow compression fitting
(fig.13), it is advisable to have the pipework
rising or falling from the elbows before routing
to the rear.
Using the template supplied, mark the hole
outline position onto the wall.
Remove the plaster and brickwork (or
plasterboard) to the depth required and chase
out the additional areas of wall to facilitate

The final separation between pipe centres needs
to be 160mm (fig.14).
160m
Offer the fixing bracket up to the wall.
Centralise and mark the four holes. Drill and
plug the holes using the wall plugs provided
(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 obtainable from most hardware stores).

IT IS PREFERABLE TO FLUSH THE
PIPEWORK (fig.15) TO CLEAR THE SYSTEM
OF DEBRIS AND CHECK FOR LEAKS BEFORE
CONNECTING TO THE MIXER.
Important: The inlet elbows contain water
filters that may become blocked if debris is
not flushed through prior to fitting.
Remove the plugs from the mixer valve inlets
and outlet. Fit the outlet adaptor for connection
to the bulkhead.
Make sure the inlet elbows are facing the
correct way. Offer the mixer up to the fixing
bracket, fit and secure using the grub screws
provided.
Complete the pipework to the mixer valve
marking off the length to enter the elbows.
NOTE: Sufficient free play must be left in the
pipework to allow withdrawal from the
compression fittings.
DO NOT secure the incoming pipes within one
metre of the shower mixer.
Remove the mixer and cut the pipes to length.
Refit the mixer to the fixing bracket and
pipework. Tighten the inlet nuts and valve body
grub screws.

MAKING GOOD
Place the tiling shroud over the shower mixer
and secure temporarily. Make good the
incoming and outlet pipe channelling and
around the bulkhead outlet. Plaster or tile up to
the edge of the shroud.
NOTE: The tiles must be accurately cut to
match the profile of the shroud. The outer
cover will then accurately seal the hole, and
enable the mixer unit to be removed from the
mounting bracket without the need to break
any tiles.
Ensure the grout lines are flush with the tiles in
order to provide a smooth sealing surface for
the outer cover. When complete, remove the
tiling shroud.
10
Concentric thermostatic mixer shower
FITTING THE FACE PLATE
Fit the face plate over the protruding controls
and slide tight to the wall. Ensure the seal in the
aperture stays in place as it slides over the valve
body. A smear of liquid soap on the seal will
ease this procedure.
Fig.18
The face plate incorporates a silicon sponge
backing that seals against a smooth wall.
On the Thames model remove the control
levers before attempting to fit the face plate.
Refit once the face plate is in place.
BULKHEAD ASSEMBLY
Fig.19
Screw the bulkhead elbow to the bulkhead
body with the three screws supplied.
Screw the completed assembly onto the
threaded connector temporarily to mark the
position of the two fixing holes (fig.18) for
securing the bulkhead to the wall.
NOTE: If screw thread protrudes too far out of
the wall, it can be be cut to the correct length
using a hacksaw.
Unscrew and remove the bulkhead assembly.
Check the location of the pipe in the wall
before drilling. Drill and plug the holes using
the wall plugs supplied.
(The wallplugs provided are suitable for most
brick walls – use an appropriate masonry drill,
but if the wall is plasterboard or soft building
block, you must use special wallplugs and an
appropriate drill bit obtainable from most
hardware stores).
If fitting to a hollow wall structure, it may be
preferable to secure the bulkhead by applying a
bead of silicon seal to the back of the bulkhead.
Apply PTFE tape to the threaded connector.
Screw the bulkhead assembly onto the threaded
connector until tight to the wall and the two
fixing holes are aligned. Secure to the wall with
the two screws supplied (fig.19).
Finally, finish by clipping the cover onto the
bulkhead ensuring the protruding legs locate in
the bulkhead body.
At this point, refer to the ‘commissioning
procedure’ in order to establish the correct
maximum shower temperature.

FITTING THE RISER RAIL
Fig.20
Fig.21
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.
Fig.22
Decide the position for the rail on the wall
within the shower area. Proceed as follows: The
sprayhead holder is supplied already attached
to the riser rail unit and the angle of the holder
dictates the rail top and bottom. The correct
orientation of the rail is when the sprayhead
holder is sloping DOWN (fig.20).
Slide the supplied soap dish onto the riser rail
below the sprayhead holder (fig.21).
Slide the top and bottom finishing trims onto
the riser rail (fig.22).
Push the two fixing brackets into the ends of
the riser rail (fig.23).
Offer the rail assembly to the wall (fig.24).
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. Ensure the rail is aligned
vertically.
Fig.24
Drill and plug the wall.
Fig.23
(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 obtainable from most hardware stores).
Screw to the wall with the fixing screws
supplied.
12
Concentric thermostatic mixer shower
Slide the finishing trims onto the brackets.
Ensure 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.25).
Fig.25
To remove a trim, push a small screwdriver or
similar through the slot in the trim end and
carefully pull away from the wall bracket.
Slide the soap dish down the rail so that its
bracket engages on top of the lower finishing
trim.
Adjusting the sprayhead holder
The holder is supplied already attached to the
rail unit. To adjust the height, press the button
underneath the holder to release the locking
mechanism (fig.26). Still pressing the button,
move the holder up or down to suit user’s
requirement.
Hose and sprayhead
Feed the flexible hose through the soap dish
aperture (fig.27) so the dish acts as a retaining
ring (Water Regulations).
Fig.26
Screw the flexible hose to the bulkhead and
sprayhead ensuring the supplied washers are in
place at both ends of the flexible hose (fig.28).
Place the sprayhead into the holder and check
that it fits correctly (fig.29).
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.

bezel anti-clockwise until a ‘stop’ is felt.
Overcome the ‘stop’ by continuing to turn anticlockwise until the cartridge and bezel come
out.
Clean the cartridge with a suitable brush or
preferably leave to soak overnight in a mild
proprietary descalent. Ensure all traces of scale
are removed and thoroughly rinse in clean
water afterwards.
Refit the cartridge by screwing in clockwise until
tight and replace the sprayhead on the hose.
