INTRODUCTION
This book contains all the necessary fitting and
operating instructions for your Triton dual control
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.
Care taken during the installation will ensure a
long and trouble free life from the shower.
This thermostatic shower valve has been
independently tested and approved to all the
requirements of
Specification D08 Thermostatic Mixing Valves
(Healthcare Premises) to the following
designations and for the following applications:
HP-S Shower with supply pressures of
LP -S Shower with supply pressures of
For optimum performance within the specified
running pressure range a minimum flow of 8 litres
per minute should be available to both inlets.
The valve is suitable for fully modulating
type combination boilers and multi-point hot
water heaters. Also suitable for thermal
storage, unvented systems and pumped
gravity systems.
Important: Before installing with a gas
instantaneous water heater, ensure the
appliance is capable of hot water delivery at
a minimum switch on flowrate 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 by 45°C.
Water temperature at the inlet to the mixer
must remain relatively constant when
flowrate adjustments are made.
The valve unit can be fitted in any orientation. For
a wall mounted sprayhead installation, the
plumbing will be simplified if the outlet is fitted
upwards.
The valve is supplied with an integral single check
valve and integral large area filter on each inlet.
Inlet connections are by compression fittings for
NHS Estates Model Engineering
1 - 5 Bar and unrestricted flow rate.
0.2 - 1 Bar and unrestricted flow rate.
15mm copper pipe.
This valve unit is supplied with a mounting bracket
to suit installation in a chased out cavity in a solid
wall, a stud partition wall, dry lined wall or fixing
to a shower cubicle or panel. It is also supplied
with an attached tiling shroud which provides
protection for the unit.
SAFETY WARNINGS
1
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.
2 DO NOT choose a position where the shower
could become frozen.
3 The outlet of this appliance must not be
connected to any form of tap or fitting not
recommended by the manufacturer.
4 The sprayhead must be cleaned regularly to
remove scale and debris.
5 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.
6 If it is intended to operate the shower in areas
of hard water it is advisable to fit a scale
inhibitor.
7 If it is intended to operate the shower outside
the guidelines laid out in the requirements
then see NOTE below.
NOTE: In the event of items 2 and 7, contact
Triton Customer Service for advice.

SITE REQUIREMENTS
The installation must be in accordance with Water
Regulation Byelaws and BS6700.
Minimum running water pressure: 0.2 bar.
Maximum running water pressure: 5 bar.
Maximum static water pressure: 10 bar.
For optimum performance within the specified
running pressure range a minimum flow of 8 litres
per minute should be available to both inlets.
Whilst the mixer valve 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 valve.
For optimum performance of this shower both hot
and cold water supplies to the shower valve
should be fed at nominally equal pressures.
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/combi boilers or
multi-point 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.
Water temperature requirements
Maximum hot water temperature 80°C
Recommended maximum 65°C
Minimum hot water temperature 52°C
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 affects of scale in hard water areas.

INSTANTANEOUS WATER HEATERS
APPLIANCE CAPABILITIES
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 by
45°C (81°F) and delivering a flow rate of not less
than 8 litres per minute.
A flow limiter is supplied for the insertion into the
shower head which controls the maximum flow of
8 litres per minute.
To fit the flow limiter unscrew the shower head
from the ball joint. Insert the flow limiter flat face
up into the shower head (fig.5) fit the flat face
washer and refit the shower head to the ball joint.
With the flow limiter fitted and when the system
is in use, the on/off flow control should be turned
fully anti-clockwise to full flow setting.

PREPARING THE MIXER VALVE
Check the contents to ensure all parts are present.
Ensure the supplied metal fixing bracket, tiling
shroud, cranked spanner, lock nut key and allen
key are all to hand.
Before commencing the installation, make sure all
the apertures on the valve are carefully covered to
prevent ingress of any debris etc.
The valve unit is supplied with a mounting bracket
to suit installation in a chased out cavity in a solid
wall, a stud partition wall, dry lined wall or fixing
to a shower cubicle or panel. It is also supplied
with an attached tiling shroud which provides
protection for the valve both for transit and on
site. It should be left on at all times until such time
when it is being installed.
The hot and cold water pipes should not be
permanently attached to the wall closer than 2m
from the valve prior to installation to allow for
final adjustment of the valve position.
SITING OF THE SHOWER
WARNING:
THE SHOWER MUST NOT BE
POSITIONED WHERE IT WILL BE SUBJECT TO
FREEZING CONDITIONS.
Refer to fig.6 for correct siting of the shower.
Position the shower and sprayhead on the wall so
that all controls can be comfortably reached whilst
using the shower. The spray head can be
positioned either side of the shower.
The valve unit can be fitted in any orientation. For
a wall mounted sprayhead installation, the
plumbing will be simplified if the outlet is fitted
upwards.

a) General conditions
NOTE: The outlet of the shower must not be
connected to any tap or fitting not
recommended by Triton Plc.
DO NOT use jointing compounds on any pipe
fittings for the installation.
Use only the compression fittings supplied. DO
NOT solder fittings within the vicinity of the
valve unit as heat transfer can damage the seals
and thermostatic components.
NOTE: Suitable isolating valves (complying with
Water Regulation Byelaws) 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.
When connecting pipework avoid using tight
90° elbows. Swept or formed bends will ensure
optimum performance.
The valve unit can be fitted in any orientation
(fig.7), but for a wall mounted sprayhead
installation, the plumbing will be simplified if
the outlet is fitted upwards. Access to the
integral strainers will also be improved with this
configuration.
The hot water inlet is identified with a red mark,
the cold water inlet with a blue mark. The
swivel inlets allow for either rising or falling hot
and cold water supplies. Note the swivel inlets
have ‘O’ seals to the body and do not require
PTFE tape or other means of sealing.
Gently screw the swivel inlets into the body of
the valve unit and stop as soon as resistance is
felt. Then back off by up to 1.5 turns to align
the inlet with the hot and cold supply pipes.
THE SWIVEL INLETS MUST NOT BE TIGHTENED
AGAINST THE VALVE BODY TO MAKE A SEAL
(fig.8).
The Triton dual control mixer valve includes a
mounting bracket which allows the installer to
mount the shower into a solid, stud partition or
other hollow wall structures. The bracket can
also be used for fitting in a shower cubicle or
panel providing the back of the cubicle or panel
is accessible.

When installing into a stud partition or other
hollow wall structure the installer may wish to
consider fabricating rear supports or other
options. Such options are beyond the scope of this
guide.
Before starting, ensure the available depth of
recess or cavity is at least 65 mm (fig.9) measured
from the face of the wall upon which the
mounting bracket is screwed (excluding the tile
thickness).
The allowance for varying thickness of tiles up to
10mm is accommodated by a limited degree of
tolerance between the control knobs and their
trim rings.
If the valve unit is to be fitted behind an existing
wall panel, use the supplied self-adhesive template
(fig.16) as a guide when cutting the aperture.

b) Valve installation in a solid wall
Remove the tiling shroud if fitted to the valve unit.
The shroud is retained by a 2.5mm hex socket
screw, replace the screw in the valve immediately
to avoid it being lost.
Decide on the shower position and determine
whether the hot and cold water supplies will enter
the shower from the top (falling) or bottom
(rising) or rear.
The building depth should be at least 70mm deep
from the surface of the wall. It is recommended to
use the supplied mounting bracket (fig.10) at all
times when installing the shower valve. It provides
the correct visible amount of shower control
through the face plate when the installation is
complete. There is limited tolerance between the
control knobs and trim rings to allow for varying
thickness of tiles up to 10mm.
As a guide for the size of hole, place the tiling
shroud on the wall and trace around it (fig.11).
Remove the plaster and brickwork to the required
depth and chase out any additional areas of the
wall to facilitate pipework to and from the valve.
Offer the mounting bracket up to the wall and
mark the four outer plain holes (fig.12). Remove
the bracket then drill and plug the wall. Screw the
bracket to the wall. Route the pipework to valve
position.
Flush out the pipework in accordance with
Water Regulation Byelaws .
Offer the valve up to the mounting bracket, and
secure using the four screws provided.

c) Valve installation in a hollow wall
The wall mounting bracket supplied with the
shower is suitable for use on a plasterboard wall
of 10mm - 13mm thickness.
Decide on the shower position and determine
whether the hot and cold water supplies will enter
the shower from the top (falling) or bottom
(rising) or rear.
The hollow cavity should be at least 65mm deep
from the surface of the wall. It is recommended to
use the supplied mounting bracket (fig.10) at all
times when installing the shower valve. It provides
the correct visible amount of shower control
through the face plate when the installation is
complete. There is limited tolerance between the
control knobs and trim rings to allow for varying
thickness of tiles up to 10mm.
Mark the route of the incoming and outgoing
pipework. As a guide for the size of hole, place
the tile shroud on the wall and trace around it
(fig.11).
Take out the plasterboard and offer the mounting
bracket up to the wall and mark the four outer
plain holes (fig.13). Remove the bracket and drill
the wall.
Two additional flat brackets are supplied for
hollow wall fixing. Slide the ‘T’ piece section
through the slot either side of the mounting
bracket then insert it into the wall cavity and
position the two flat brackets in line with the
outer holes (fig.14). Secure using the bolts
provided. Route the pipework to the valve
position.

d) Valve installation in a panel or cubicle
To use the wall mounting bracket supplied with a
shower cubicle or a laminated panel, wooden
blocks are required to increase the depth of the
bracket. These blocks need to increase the depth
of the bracket to between 70.5 mm and 76.5 mm
from the finished surface (fig.15).
Decide on the shower position and determine
whether the hot and cold water supplies will enter
the shower from the top (falling) or bottom
(rising) or rear.
Mark the route of the incoming and outgoing
pipework. Only the two holes for the control
knobs require to be cut out of the panel or
cubicle. Use the supplied template as a guide
(fig.16).
After cutting the two holes, fit the valve to the
mounting bracket and secure using the four
screws provided.
Offer the valve and mounting bracket up to the
back of the panel ensuring the thermostatic and
on/off assemblies are protruding and centralised
through the apertures. Mark the four inner tapped
holes (fig.17). Remove the valve and bracket and
drill the panel and wooden blocks. Route the
pipework to valve position.
Flush out the pipework in accordance with
Water Regulation Byelaws .

CONNECTING THE SUPPLY PIPES
Gently screw the swivel inlets into the body of the
valve unit and stop as soon as resistance is felt.
Then back off by up to 1.5 turns to align the inlet
with the hot and cold supply pipes. THE SWIVEL
INLETS MUST NOT BE TIGHTENED AGAINST THE
VALVE BODY TO MAKE A SEAL.
Connect the hot water supply to the inlet marked
RED, and connect the cold water supply to the
inlet with the BLUE mark.
Remember the swivel inlet has an ‘O’ ring seal and
that no other sealing means is required.
Tighten the compression fittings with the cranked
spanner, supplied for when access is restricted.
Ensure the on/off assembly is turned to the off
position by temporarily fitting the on/off control
and turning clockwise until resistance is felt.
Open the supplies and test for leaks in the
pipework upstream of the valve.
OUTLET ADAPTOR
The mixed water outlet adaptor needs to be
removed and replaced using PTFE tape to ensure a
water tight seal.
NOTE: The outlet adaptor is reversible with one
side suitable for connection to a flexible hose –
flat end (fig.18), and the other is a chamfered end
for a 15 mm compression fitting.

FITTING THE FIXED HEAD
Complete outlet pipework from the valve ending
in a 1/2” BSP female threaded fitting – not
supplied (fig 19).
Note the depth of thread on the fixed head unit
from the finished wall surface is 10mm (fig 20). It
is advisable that pipework installed in solid walls
be provided with sufficient free play inside a cavity
to enable any slack to be accommodated.
At this point it is advisable to fit a blanking plug in
the female fitting, turn on the valve and check for
leaks from the outlet fittings.
Make good the wall, tiling etc.
Screw in place the showerhead arm and mark the
position of the three fixing holes (fig 21).
Drill and plug the holes using the plugs supplied.
NOTE: If fitting to a hollow wall structure, use
suitable cavity wall fixtures.
Apply PTFE tape to the 1/2” BSP thread on the
shower head arm before fitting.
Secure the showerhead arm to the wall with the
three screws supplied (fig 22) .
Screw the ball swivel and locking ring onto the
end of the showerhead arm (fig 23) ensuring the
‘O’ ring is in place.
NOTE: The ball swivel must be screwed on tight in
order to provide a water tight connection. The use
of an appropriate tool may be used if necessary.
Screw on the fixed showerhead ensuring the
supplied tapered sealing washer is in place as
shown in (fig 24). The showerhead must be
screwed on tight in order to ensure a water tight
connection.

USING THE TILING SHROUD
The tiling shroud will need a section removed
(fig.25) in order to accommodate the mounting
bracket.
Replace the tiling shroud over the mixer valve.
Plaster or tile up to the edge of the shroud. Note
that if the tiles are accurately cut to match the
profile of the shroud, then the face plate will seal
around the hole in the tiles, and the valve unit will
be able 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
face plate.
FITTING THE FACE PLATE AND KNOBS
Unscrew the face plate retaining rings from the
valve unit (if fitted).
See fig.26 for the assembly of parts. Position the
face plate over the valve unit and place the trim
rings onto the face plate ensuring the indicator
notch is in the 12 ‘o’ clock position. It must be in
this position regardless in which orientation the
unit is mounted.
Secure by screwing on the two brass face plate
retaining rings.
Gently tighten the rings by hand until the face
plate clamps gently against the wall. Do not overtighten or the face plate may distort. The face
plate incorporates a silicon sponge seal which will
satisfactorily seal against a smooth wall.
Temperature control knob assembly
Place the temperature knob temporarily onto the
splined adaptor, and rotate fully anti-clockwise.
Remove the knob and reposition onto the splined
adaptor again, but this time ensuring the ceramic
tap handles are in a 2 o’clock and 10 o’clock
position (fig.27).
Screw the locknut down against the knob and
tighten using the key supplied. Do not fit the
finishing cap just yet as when the commissioning
is carried out, the maximum temperature
adjusting screw may have to be altered.

COMMISSIONING
(The following conforms to NHS Estates Model
Engineering Specification D08 for when the mixer
has been installed in healthcare premises).
ENSURE THAT ALL SUPPLY PIPEWORK HAS BEEN
FLUSHED THROUGH PRIOR TO COMMISSIONING.
Ensure that both hot and cold water supplies are
fully open and at (or near to) their design
temperature and pressures and are within the
requirements as stated.
Set the temperature control to the maximum
temperature setting – by rotating the knob fully
anti-clockwise until resistance is felt.
Open the on/off control by turning it anticlockwise. Placing a burst polythene bag over the
shower head will catch and deflect the spray
during commissioning.
Allow the shower to run at maximum temperature
setting until the water temperature has stabilised.
Should the temperature rise in an uncontrolled
manner, then the hot and cold supplies are
probably reversed. This must be corrected before
proceeding further.
The mixer valve is factory set to provide a
maximum outlet temperature of 39°C but this
should be checked on site to ensure the setting
has not been altered and also to ensure user
safety.
Should the maximum temperature require
adjustment, remove the temperature knob
finishing cap (if it has been placed in position
when assembling the temperature controls
previously) . Adjust the small slotted screw in the
centre of the spindle (fig.28) – anti-clockwise to
increase the temperature, clockwise to decrease
the temperature.
The maximum temperature should not exceed
41°C. For installations complying with NHSE
specifications.
After setting the maximum temperature, turn the
shower on and off several times and check the
maximum setting is correct. Record the
commissioning data on the maintenance record at
the rear of this book in order for the in-service
performance of the mixer valve to be assessed.
Finally, check the thermal shut off facility of the

valve by performing a thermal shut off test. Shut
off the cold supply. The flow from the shower
should stop immediately or reduce to a trickle in
which case the water temperature should be less
than 43°C.
In either case there is no risk of scalding.
If however the temperature is above 43°C then it
is likely there is contamination in the valve
preventing it from shutting off the hot supply. In
this case refer to the maintenance section or
contact Customer Service.
In domestic installations where D08 specification is
not required, the maximum temperature setting
should not exceed 45°C.
OPERATING THE SHOWER
To start the shower, rotate the on/off control fully
anti-clockwise (fig.29) for maximum flow.
To stop the water flow, rotate the on/off control
fully clockwise (fig.30) until resistance is felt.
To adjust the water temperature, rotate the
temperature control – clockwise in the direction of
the cold arrow (fig.31) for a cooler shower or anticlockwise in the direction of the hot arrow (fig.32)
for a hotter shower.

When cleaning the external faceplate and
knobs, never use cleaners containing
abrasives or solvents as they may damage
the chrome plating. Use only soap and a
soft cloth.
MAINTENANCE
(The following maintenance procedure must be
carried out for commercial and health care
premises, but is not necessarily required for
domestic installations).
Maintenance of the unit is required to ensure
continued performance after installation and that
it continues to provide scald prevention.
The frequency of routine maintenance of the
internal of the valve will depend mainly on the
water supply condition. Local knowledge will
dictate suitable intervals. In addition, the following
precautions should be observed:
a) Initially check the strainer baskets (fig.33) for
debris once every three months and clean if
necessary. This period can be increased if
appropriate once the general condition and
cleanliness of the water is established. Where the
water supplies come from beneath (rising) the
mixer valve, lifting out the strainer basket may not
remove all of the trapped debris. Full flushing out
may be necessary if debris is found or suspected.
b) Perform a thermal shut off test every three
months, and check the maximum temperature
setting. See the ‘Commissioning’ section for the
details of this test and re-adjustment of the
maximum temperature setting if required.
c) If the maximum water temperature varies by
more than 2°C from the commissioned setting
then ensure the strainers are clean and that the
isolating valves are fully open. Test the non return
valves as described below. If these tests do not
highlight the reason for the temperature variation,
then follow the procedure below for investigating
failure of the thermal shut off test.
d) If the mixer valve fails the thermal shut off
test then remove the knobs, faceplate and control
valve cover. Check the internal surface for scaling.
If the body requires descaling then it should be
removed from the pipework to carry this work out
– the valve should be able to be removed through
the aperture without breaking tiles. All rubber
parts must be removed prior to descaling. The
slide valve seal (fig.34) located inside the body
should always be replaced with a new seal after
removal. Maintenance kits are available which
contain ‘O’ rings and/or the thermostatic element.

DC7000 ANTIQUE
Smear all ‘O’ rings with silicon grease prior to
installing them. Torque the valve cover to 13 Nm
(10 lb.ft.). This is to prevent inadvertently
unscrewing the cover during temperature
adjustment. Do not over-tighten the valve cover or
the mounting arrangement may be damaged.
e) Replace the ‘O’ rings every three years –
maintenance kits with spare ‘O’ rings are
available. Smear silicon grease on all ‘O’ rings
before assembling. At the same time replace the
slide valve assembly (fig.34). Lightly smear the
outside diameter with silicon grease before
installing.
f) Replace the thermostatic element (fig.34) at
least once every six years, or more often if
problems are experienced or in installations where
water is particularly hard.
g) The on/off mechanism (fig.35) has a 1/2” tap
washer which should be replaced when it is found
to be leaking. Remove the trim plate and unscrew
the on/off assembly. The washer is retained by a
small nut. When replacing, do not overtighten –
torque to 25Ncm. Ensure the on /off assembly is
torqued down to 13Nm (10 lb.ft.) to prevent the
user from inadvertently unscrewing the assembly
during flow control. Do not over-tighten the
assembly or the mounting arrangement may be
damaged.
h) The non return valves (NRVs) prevent crossflow between hot and cold supplies under
unequal pressure conditions. They are designed
for long life with no maintenance. Their function
can be tested as follows:
i) To test the NRV on the hot side, shut off the
hot supply and ensure the cold supply is open. Be
prepared for leakage of trapped water in the pipe
and remove the strainer basket on the hot side.
Evidence of continuing leakage from the strainer
body is coming through the hot supply NRV.
j) To test the NRV on the cold side, shut off the
cold supply and ensure the hot supply is open. Be
prepared for leakage of trapped water in the pipe
and remove the strainer basket on the cold side.
Evidence of continuing leakage from the strainer
body is coming through the cold supply NRV.
If either NRV is leaking then the inlet elbow –
complete with NRV and strainer basket, should be
replaced. It is not possible to satisfactorily remove
the NRV itself from the elbow and should not be
attempted.
IN-SERVICE TESTING
Periodic testing should be undertaken to check
whether deterioration has occurred in the
performance of the mixer valve.
A thermal shut off test, as described under
maintenance, should be carried out. If water
coming from the shower head is at a temperature
of more than 2°C above the maximum mixed
water temperature setting then the valve unit is
due for maintenance.
NOTE: A thermostatic mixing valve in need of
maintenance can be undetectable in normal use
and only becomes apparent when a disruption
occurs in the hot or cold water supply
temperatures or pressures.
The frequency of in-service testing depends upon
the water condition passing through the unit. Inservice testing should be between six to twelve
months, but less than six month intervals in areas
of hard water.
Experience of local conditions and the in-service
testing record will dictate the frequency of inservice testing.
