Concentric built-in thermostatic mixer valve
INTRODUCTION
Water minimum flow rate
This book contains all the necessary fitting and
operating instructions for your Triton mixer
shower. Please read them carefully and read
through the whole of this book before beginning
your installation.
For best performance within the specified running
pressure range a minimum flow of 8 litres per
minute should be available to both inlets.
The shower installation must be carried out by
a suitably competent person and in sequence of
this instruction book.
Maximum hot water temperature: = 80°C
Care taken during the installation will give a long
and trouble free life from your mixer shower.
Maximum cold water temperature: = 20°C
Water temperature requirements
Minimum hot water temperature:
= 52°C
Minimum temperature differential: = 10°C
The mixer shower MUST NOT be subjected to
water temperatures above 80°C.
The installation must be in accordance with
Water Regulations and Bylaws.
BS 6700 recommends that the temperature of
stored water should never exceed 65°C.
Water pressure requirements
Running water pressure:
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.
- 0.2 bar min.
1.0 bar max.
Mains fed (HP)
= 65°C
Minimum cold water temperature: = 5°C
SITE REQUIREMENTS
Gravity fed (LP)
TMV3 Recommended maximum:
- 1.0 bar min.
Water temperature adjustment and
5.0 bar max.
thermal safety
Maximum static water pressure:
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.
Gravity and mains - 10 bar
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 UK up to a maximum of 5 bar running
pressure.
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.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
Pressure reducing valve
SAFETY WARNINGS
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.
a. DO NOT choose a position where the shower
could become frozen.
b. DO NOT connect this mixer shower to any
form of tap or fitting not recommended by
the manufacturer.
c. DO NOT allow the inlet pressure or flow
rates to operate outside the guidelines laid
out in ‘site requirements’.
d. DO NOT connect the mixer shower to a
gravity hot supply and a mains cold supply
(or vice versa).
Replacement parts can be ordered from Triton Customer
Service. See ‘spare parts’ for details and part numbers.

Concentric built-in thermostatic mixer valve
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 Triton
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.
IMPORTANT:
b. For best performance the showerhead MUST be
regularly cleaned to remove scale and debris.
• 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.
WATER SYSTEM REQUIREMENTS
This mixer shower is suitable for: -
• The pipe-work should be installed such
that other taps and appliances being
operated elsewhere on the premises do not
significantly affect the flow.
• Gravity water systems
• Pumped gravity systems.
• Fully modulating type combination boilers
• When connecting pipe-work avoid using
tight 90° elbows; swept or formed bends will
give the best performance.
• Multi-point hot water heaters.
• Thermal storage,
• The hot water pipe entry must be made to
the left-hand side inlet, marked HOT, ‘H’ or
with a red/orange label.
• Unvented systems
When installing this mixer with a Combination or
multi-point boiler, it may be necessary to install
flow regulation.
• 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.
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 backflow prevention devices must be
installed with this product in accordance with the
water supply (water fittings) Regulations 1999.
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.
• The mixer inlets contain removable filters
that may become blocked if debris is not
flushed through before fitting.
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.
(Commercial applications)
• 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 hot supply temperature MUST remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.

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.

Concentric built-in thermostatic mixer valve
Note that the valve body requires a deeper recess
than the inlet and outlet fittings.
Fig.8
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.8).
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 or
tiling shroud as a template). Offer the valve body
up to the fabrication and mark the two fixing
holes.
Remove the valve and drill the holes. Route the
pipework to the valve position.
Installation in a panel 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 one hole to be cut out of the
panel or cubicle. Use the coverplate as a template
to mark the hole positions then extend further to
allow access for the filters.
Route the pipework to valve position.

Mark the position of the four locating screws
for the mounting plate, although if installing to
a solid brick wall using two diagonal holes will
usually be enough.
Drill and plug the holes using the wall plugs
provided. (The wall plugs 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 wall plugs and a
suitable drill bit).
Fit the mounting plate using the screws supplied
(fig.9).
The inlet elbows allow for either rising, falling
or rear entry hot and cold water supplies. The
elbows have ‘O’ ring seals (fig.6) to the body
and do not require PTFE tape or other means of
sealing.

MAKING GOOD
Make good the wall and complete the tiling.
• This product is supplied with a tiling shroud
to prevent damage to the product.
• If the tiles are accurately cut, then the
faceplate will seal around the hole in the
tiles, and the valve unit will be able to be
removed from the wall without the need to
break any tiles.
Make sure the grout lines around the valve are
flush with the tiles in order to provide a smooth
sealing surface for the coverplate.

BULKHEAD ASSEMBLY
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 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 holes using the wall plugs
supplied. (The wall plugs 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 wall
plugs and a suitable drill bit).
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.15).
Finish by clipping the cover onto the bulkhead,
making sure the protruding legs locate in the
bulkhead body.

Flow regulation
Fig.17
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 a flow regulator
To fit the flow regulators, unscrew the elbows.
Place the flow regulator, correctly, into the inlet
nut connector followed by the retaining washer.
Reassemble the elbows (fig.16).
ANTI-SCALD PROTECTION
Grub screws
(2 off)
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.
Fitting the coverplate
Fit the coverplate over the valve body and slide
tight to the wall.
Make sure the seal in the opening stays in place
as it slides over the valve body. A smear of liquid
soap on the seal will ease this procedure.
The coverplate incorporates a silicon sponge
backing that seals against a smooth wall.
Once the plate has been fitted, the two
adjustment levers will need to be fitted into the
body of the mixer and tightened (fig.17).

COMMISSIONING (TMV3)
The following conforms to NHS Estates Model Engineering Specification D08 for when
the mixer has been installed in healthcare premises.
Important: Make sure that all supply pipework has been flushed through before
commissioning.
The maximum temperature should not exceed 41°C.
Start the water flow by rotating the flow control.
Make sure that both the 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.
Make sure the temperatu­re control is at the maximum temperature setting.
Allow the shower to run at the maximum temperature setting until the water temperature
has stabilised. Rotate the temperature control until your desired maximum showering
temperature is reached.
The mixer has a temperature stop to prevent accidental rotation to higher
temperatures. This is adjustable to provide a maximum temperature of 41°C
and should be checked on site to guarantee user safety.
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
stopping 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 46°C.
Temperature adjustment range
The mixed water temperature can be adjusted from cold through to a top limit (which can be
pre-set during installation – factory set at approximately 38°C) with full anti-scald protection
throughout the range.

ADJUSTING THE MAXIMUM
TEMPERATURE SETTING
(and fitting the levers)
Fig.18
The mixer valve is supplied with the flow and
temperature control fitted and the maximum
temperature stop factory set to 38°C (this can be
adjusted during installation).
The levers are supplied loose in the box.
To adjust the maximum temperature setting
remove the temperature control using a
suitable allen key. Allow the water to run until
the temperature has stabilised. Adjust the
temperature control spindle by hand (fig.18).
When the showering temperature is satisfactory
turn off the shower.
Refit the temperature control, making sure the
maximum temperature stop pin is as close to
the flat edge of the over ride stop as possible
(fig.19).

IN SERVICE TESTING
With an acceptable mixed water temperature,
complete the following procedure:
The following procedure must be carried out for
commercial and health care premises, but is not
necessarily required for domestic installations.
a) record the temperature of the hot and cold
water supplies
b) record the temperature of the mixed water at
the largest draw-off flow rate
Maintenance of the unit is required to give
continued performance after installation and that
it continues to provide scald prevention.
c) record the temperature of the mixed water
at a smaller draw-off flow rate, which shall be
measured
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.
d) isolate the cold water supply to the mixing
valve and monitor the mixed water
temperature
e) record the maximum temperature achieved
as a result of (d) and the final stabilised
temperature
Purpose
The purpose of in-service tests is to regularly
monitor and record the performance of the
thermostatic mixing valve. Deterioration in
performance can indicate the need for service
work on the valve and/or the water supplies.
f) record the equipment, thermometer etc.
used for the measurements
If at step (e) the final mixed water temperature
is greater than the values in Table 17 and /
or the maximum temperature exceeds the
corresponding value from the previous results by
more than about 2 K, the need for service work
is indicated
Procedure
Using the same measuring equipment or
equipment to the same specification as used
in the commissioning of the valve, adjust the
temperature of the mixed water in accordance
with the manufacturer’s instructions and the
requirement of the application. Carry out the
following sequence:
NOTE: In-service tests should be carried out
with a frequency, which identifies a need
for service work before an unsafe water
temperature can result. In the absence of any
other instruction or guidance, the procedure
described in Annex F of D 08 may be used
a) record the temperature of the hot and cold
water supplies
b) record the temperature of the mixed water at
the largest draw-off flow rate
Annex F of D 08 (informative)
c) record the temperature of the mixed water
at a smaller draw-off flow rate, which shall be
measured
If the mixed water temperature has changed
significantly from the previous test results (e.g.>
1 K) 5), record the change and before readjusting the mixed water temperature check:
a) that any in-line or integral strainers are clean
b) any in-line or integral check valves or other
anti-back siphonage devices are in good
working order
c) any isolating valves are fully open

In the absence of any other instruction or
guidance on the means of determining the
appropriate frequency of in-service testing, the
following procedure may be used:
a) 6 to 8 weeks after commissioning carry out
the tests detailed in
“In-Service Tests”
b) 12 to 15 weeks after commissioning carry
out the tests detailed in
“In-Service Tests”
Depending on the results of the above tests,
several possibilities exist:
a) If no significant changes (e.g. ≤ 1 K) in
mixed water temperatures are recorded
between commissioning and 6 to 8 week
testing, or between commissioning and
12-15 week testing the next in-service test
can be deferred to 24 to 28 weeks after
commissioning.
b) If small changes (e.g. 1 to 2 K) in mixed
water temperatures are recorded in only one
of these periods, necessitating adjustment of
the mixed water temperature, then the next
in-service test can be deferred to 24 to 28
weeks after commissioning.
c) If small changes (e.g. 1 to 2 K) in mixed
water temperatures are recorded in both of
these periods, necessitating adjustment of
the mixed water temperature, then the next
in-service test should be carried out at 18 to
21 weeks after commissioning.
d) If significant changes (e.g. > 2 K) in mixed
water temperatures are recorded in either
of these periods, necessitating service work,
then the next in-service test should be carried
out at 18 to 21 weeks after commissioning.
The general principle to be observed after the
first 2 or 3 in-service tests is that the intervals of
future tests should be set to those which previous
tests have shown can be achieved with no more
than a small change in mixed water temperature.
Note: A testing record page has been added to
the back of the book for your use.
