INTRODUCTION
Water temperature requirements
This book contains all the necessary fitting and
operating instructions for your mixer shower.
Please read them carefully and read through
the whole of this book before beginning your
installation.
Recommended maximum:
= 65°C
Minimum hot water temperature:
= 55°C
Maximum cold water temperature: = 25°C
NOTE: Valves operating outside these conditions
cannot be guaranteed by the Scheme to operate
as Type 2 valves.
The shower installation must be carried out by
a suitably competent person and in sequence of
this instruction book.
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.
Care taken during the installation will give a long
and trouble free life from your mixer shower.
SITE REQUIREMENTS
Water temperature adjustment and
thermal safety
The installation must be in accordance with
water supply (water fittings) regulation 1999
and/or local Bylaws.
The mixed water temperature can be adjusted
from cold through to a top limit which must
be preset 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.
Water pressure requirements
Running water pressure:
Low pressure*
- 0.1 bar min.
Should there be a loss of flow to either incoming
supply then- water from the shower will stop or
be reduced until both supplies are restored.
1.0 bar max.
High pressure
- 0.5 bar min.
5.0 bar max.
SAFETY WARNINGS
Maximum static water pressure:
Low & High pressure
- 10 bar
a. DO NOT choose a position where the shower
could become frozen.
*This mixer shower is designed for high pressure
systems found in the UK, but can be installed
with low pressure gravity water systems with
reduced flow rates.
b. DO NOT connect this mixer shower to any
form of tap or fitting not recommended by
the manufacturer.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
c. DO NOT allow the inlet pressure or flow
rates to operate outside the guidelines laid
out in ‘site requirements’.
Pressure reducing valve
d. DO NOT connect the mixer shower to a
gravity hot supply and a mains cold supply
(or vice versa).
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 pipe work
can provide nominally equal pressures at the
mixer shower.
Water minimum flow rate
For best performance within the specified running
pressure range a minimum flow of 8 litres per
minute should be available to both inlets.
Replacement parts can be ordered from Triton Customer
Service. See ‘spare parts’ for details and part numbers.

PLUMBING REQUIREMENTS
Hard water areas
DO NOT use jointing compounds on any pipe
fittings for the installation.
a. 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 scale
inhibitor, please contact Customer Service.
DO NOT solder fittings near the mixer unit
as heat can transfer along the pipework and
damage the mixer valve.
b. For best performance the showerhead MUST
be regularly cleaned to remove scale and debris.
DO NOT subject the unit to a water temperature
above 80°C during installation, use, maintenance
or disinfection.
WATER SYSTEM REQUIREMENTS
IMPORTANT:
This mixer shower is suitable for:
• The layout and sizing of pipework MUST
be such that nominally equal inlet supply
pressures are achieved and the effects of
other draw-offs are minimised.
• Gravity water systems.
• Pumped gravity systems.
• Fully modulating type combination boilers.
• The pipe-work should be installed such
that other taps and appliances being
operated elsewhere on the premises do not
significantly affect the flow.
• Multi-point hot water heaters.
• Thermal storage.
• Unvented systems.
• When connecting pipe-work avoid using
tight 90° elbows; swept or formed bends will
give the best performance.
When installing this mixer with a Combination or
multi-point boiler, it may be necessary to install
flow regulation.
• The hot water pipe entry MUST be made to
the left-hand side inlet, marked HOT, ‘H’ or
with a red/orange label.
Check that the appliance 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 52°C
(minimum).
• Suitable isolating valves (complying with
Water Regulations and Bylaws) 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.
Water temperature at the inlet of the mixer valve
MUST remain relatively constant when flow rate
adjustments are made (refer to the applianceoperating manual to confirm compatibility with
this mixer shower).
• It is preferable to flush the pipe-work to clear
the system of debris and check for leaks
before connecting to the mixer.
(Commercial applications)
Where thermal store systems and instantaneous
gas water heaters are used, if excessive drawoff take place the appliance may not be able to
maintain an adequate output temperature.
This could result in the shower temperature
becoming noticeably cooler.
• Triton recommends for all commercial
applications that, easily accessible, in-line
filters are used to aid maintenance.
Flow regulators can be fitted with high-pressure
water systems to reduce flow rate and assist
economy.
• The mixer inlets contain removable filters
that may become blocked if debris is not
flushed through before fitting.
The hot supply temperature MUST remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.

The following are typical thicknesses and are
given as a guide only:
Tile
6 − 10mm
Adhesive
2 − 3mm
Plasterboard
9.5 − 12.5mm
Plaster finish
2 − 3mm
Maximum tile thickness to be 10mm.
When installing into a stud partition or other
hollow wall structure, the installer may wish to
consider building rear supports or other options
for fitting the mounting plate. Such options are
beyond the scope of this guide.
Use the cover plate or tiling shroud (if supplied)
as a template when cutting the opening for
installing the shower into a solid wall, stud
partition or hollow wall structure.
Max
Min
65
The building-in depth for the mounting plate is
given in (fig.11) from the plaster finish but this
is dependent upon tile and adhesive thicknesses.
90
The inlet elbows allow for either rising, falling or
rear entry hot and cold water supplies.
NOTE: To ease future requirements for cleaning
and maintenance of the unit, it is advisable to
route both the incoming and outgoing pipework
from the same direction. Access to the integral
strainers will also be improved with this layout.
Installation in a solid wall
• Decide on the shower position and determine
whether the hot and cold water supplies will
enter the shower from top (falling) or bottom
(rising) or rear.
• As a guide for the size of hole, it should be
large enough to accept the valve complete
with the inlet and outlet fittings and also
allow access for connection to the pipework.
• Remove the plaster and brickwork to the
required depth and chase out any additional
areas of the wall to give access to the
pipework to and from the valve plus any
outlet fittings. Note that the valve body
requires a deeper recess than the inlet and
outlet fittings.
9
Dual control built-in thermostatic mixer shower with diverter
NOTE: The outlet pipework must end in a suitable
female thread parallel 15mm x ½” BSP fitting
(not supplied).
• Offer the valve body up to the wall and mark
the fixing holes. Remove the valve, drill and
plug the wall. Route the pipework to valve
body position.
Installation in a hollow wall
• 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 (fig.12).
• When installing into a stud partition or other
hollow wall structures, the installer will need
to consider fabricating rear supports or other
options. Such options are beyond the scope
of this guide.
• Mark the route of the incoming and outgoing
pipework.
• Take out the plasterboard (use the cover plate
as a template). Offer the valve body up to the
fabrication and mark the fixing holes.
Fig.12
• Remove the valve and drill the holes. Route
the pipework to the valve position.
Installation in a panel wall or cubicle
When installing into a panel or cubicle structure
the installer will need to consider fabricating
rear supports or other options. Such options are
beyond the scope of this guide.
Typically, there should be at least 65mm space
from the surface of the panel to the rear of the
valve body.
IMPORTANT: Access to the rear of the valve
must be available.
• The controls require two holes to be cut out
of the panel or cubicle. Use the face plate as
a template to mark the hole positions then
extend further to allow access for the filters.
• Route the pipework to valve position.
10
Dual control built-in thermostatic mixer shower with diverter
FITTING THE MIXER
Fig.13
• Mark the position of two locating screws.
• Drill and plug the holes. (Use an appropriate
masonry drill, but if the wall is plasterboard or
a soft building block, use special wall plugs and
a suitable drill bit).
IMPORTANT: Make sure that all supply
pipework has been flushed through before fitting
the mixer (fig.13).
• Connect the hot water supply to the inlet
marked HOT, ‘H’ or red/orange label and
connect the cold water supply to the inlet
marked COLD, ‘C’ or blue label.
• Tighten all compression fittings
• Secure the mixer to the wall.
FITTING THE BULKHEAD PIPEWORK
• Complete the outlet pipework ending in
a 15mm x ½” BSP female thread elbow
(fig.14).
Fig.14
Note: This fitting is not supplied as variations
in installations require the selection of a suitable
solder or compression fitting.
• Screw the supplied male-thread connector
into the female fitting (fig.15) using PTFE
tape to give a watertight joint.
Appropriate
fitting
NOTE: The male-thread connector supplied has
a shoulder. If fitting into a flush wall, make an
additional 8mm allowance for this shoulder at
the finished surface. The connector can be cut to
size if required.
• The threaded connector should protrude from
the finished wall surface between 8mm and
13mm.
LEAK TESTING
Direct the outlet of the mixer to waste. Open the
isolating valves to the shower and check for leaks.
Remedy any leaks found.
11

BULKHEAD ASSEMBLY
• Screw the bulkhead elbow to the bulkhead
body with the three screws supplied.
Fig.16
• Screw the completed assembly onto the
threaded connector temporarily to mark the
position of the two fixing holes for securing
the bulkhead to the wall.
NOTE: If screw thread protrudes too far out of
the wall, it can 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 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).
• 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.16).
• Finish by clipping the cover onto the
bulkhead, making sure the protruding legs
locate in the bulkhead body.

Flow regulation
A flow regulator is supplied for use with highpressure water systems and may be fitted with
any of the systems listed to reduce flow rate and
assist economy.
To fit the flow regulator
To fit the flow regulators (flexible hose
connection) press it into the outlet of the
bulkhead, correctly. Please note the flow
regulator is only designed to work in one
direction (fig.17).
ANTI-SCALD PROTECTION
It is important that the mixer valve is tested
regularly to prevent the risk of scalding and
guarantee user safety. This can be carried out as
follows: with the mixer blend temperature set
at 38°C isolate the cold water supply. The outlet
flow rate will reduce to a safe level.

Fig.18
The BuildCert TMV scheme recommends the
following set maximum mixed water outlet
temperatures for use in all premises:
44°C - for bath fill but see notes below.
41°C - for showers.
41°C - for washbasins.
38°C - for bidets.
The mixed water temperatures must never
exceed 46°C at terminal fitting.
The British Burns Association recommends 37 to
37.5°C as a comfortable bathing temperature
for children. In premises covered by the Care
Standards Act 2000, the maximum mixed water
outlet temperature is 43°C.
Fitting the coverplate
Fit the coverplate over the valve body and slide
tight to the wall.
Rubber seals
Make sure the seals in the openings stays in
place as it slides over the valve body. A smear of
liquid soap on the seal will ease this procedure
(fig.18).

APPROVALS
This mixer valve is approved to the requirements of:
*BS EN 1111
*On pressures above 0.5 bar.
*WRAS
Designation:
HP-S (high pressure shower only)
TMV2 REQUIREMENTS (12 MONTHLY VERIFICATION)
It is a requirement that all TMV2 approved valves shall be verified against the original set
temperature results once a year.
On installation and on a yearly basis please perform the following checks:
1. Cold water supply isolation test
Isolating the cold water supply to the TMV, wait for five seconds if water is still flowing check that
the temperature is below 46C.
If there is no significant change to the set outlet temperature (±2°C or less change from the
original settings) and the fail-safe shut off is functioning, then the valve is working correctly and
no further service work is required.
If there is a residual flow during the commissioning or the annual check this is acceptable
providing the temperature of the water seeping from the valve is no more than 2C above the

MAINTENANCE
Cleaning
The following maintenance procedure must
be carried out for commercial and health care
premises, but is not necessarily required for
domestic installations.
It is recommended that all products are cleaned
using warm, soapy water.
Maintenance of the unit is required to give
continued performance after installation and that
it continues to provide scald prevention.
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.
It is a requirement that all TMV2 approved
valves shall be verified against the original set
temperature results once every 12 months.
a) Initially check the filters for debris once every
three months and clean if necessary.
Do not use abrasive or aggressive chemical
cleaning products as this may affect the product
surface finish and invalidate your guarantee.
Cleaning the filters (fig.A)
It is advised that this should be carried out by a
qualified person.
• Turn off the water supplies before starting.
• To gain access to the filters remove the filter
housings from the front of the unit.
• Remove the retaining clip and filter.
• Wash the filter thoroughly under running
water, use a suitable brush to remove all debris.
• Reassemble in reverse order.
Fig.A
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 readjustment of the maximum
temperature setting if required.
Circlip
Wire filter
c) If the maximum water temperature varies
by more than 2°C from the commissioned
setting then carry out the following checks
• Check the isolating valves are fully open.
• Check the internal surface for scaling.
NRV
If the body requires descaling then it should be
removed from the pipework to carry this work
out (all rubber parts MUST be removed before
descaling).
• Check the function of the non-return valves.
The non-return valves (NRVs) prevent cross-flow
between hot and cold supplies under unequal
pressure conditions. They are designed for long
life with no maintenance.
NOTE: the (NRV’s) will only operate in one direction
- water should be able to flow into the unit from the
inlets, but NOT back out through the inlets.
Filter housing
Disinfection
Where chlorine is used for the disinfection
of water systems all relevant guidelines and
approved codes of practice must be strictly
followed. Failure to comply with the relevant
guidelines and approved codes of practice may
invalidate your guarantee.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement - please see
the spare parts list.
WARNING!
DO NOT use ‘powerful’ abrasive or
solvent cleaning fluids when cleaning the
shower as they may damage the fittings.
