INTRODUCTION
pressure range a minimum flow of 8 litres per
minute should be available to both inlets.
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.
Water temperature requirements
Maximum hot water temperature: = 80°C
The shower installation must be carried out by
a suitably competent person and in sequence of
this instruction book.
= 65°C
Minimum hot water temperature:
= 52°C
Maximum cold water temperature: = 20°C
Minimum cold water temperature: = 5°C
Care taken during the installation will give a long
and trouble free life from your mixer shower.
Minimum temperature differential: = 10°C
The mixer shower MUST NOT be subjected
to water temperatures above 80°C.
SITE REQUIREMENTS
BS 6700 recommends that the temperature of
stored water should never exceed 65°C.
The installation must be in accordance with
Water Regulations and Bylaws.
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.
Water pressure requirements
Running water pressure:
Mains fed (HP)
TMV3 Recommended maximum:
- 1.0 bar min.
Water temperature adjustment and
thermal safety
5.0 bar max.
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 but with reduced flow rate.
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.
Water minimum flow rate
c. DO NOT allow the inlet pressure or flow
rates to operate outside the guidelines laid
out in ‘site requirements’.
b. DO NOT connect this mixer shower to any
form of tap or fitting not recommended by
the manufacturer.
For best performance within the specified running
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.

Thermostatic bar mixer shower
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.
• It is recommended that for all commercial
applications, 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.

fit an additional drop tight pressure-reducing
valve when the mains pressure is over 5 bar. The
drop tight pressure reducing valve MUST be
set at the same value as the unvented package
pressure reducing valve.
TO TAPS
Note: An additional expansion vessel may be
required if a second pressure-reducing valve is
installed. This does not apply to packages with a

PREPARING THE MIXER VALVE
Check the contents to make sure all items are
present.
Before starting, make sure all of the openings on
the valve are carefully covered to stop ingress
of any debris, etc. while routing the supply
pipework.
The shower valve is suitable for exposed
installation onto:
• Solid wall
• Stud partition wall
• Dry lined wall
• Laminate cubicle or panel.
Height of
showerhead
to suit user’s
requirements
SITING OF THE SHOWER & ACCESSORIES
Refer to (fig.4) for correct siting of the shower.
The mixer valve should be positioned, as
detailed, with all controls within comfortable
reach of the user.
The accessories (showerhead, riser rail and/or
fixed showerhead) can be positioned above or to
either side of the shower.
The valve must be installed in a position that
allows for easy access for future maintenance and
commissioning.
*IMPORTANT!
*SUPPLY PIPE WORK
BEFORE FIXING the supply pipework within
the wall, refer to the ‘SUPPLY PIPE WORK’
and ‘STRAIGHT FITTINGS’ sections.
See figures 5, and 6 to ensure
the MINIMUM of 7mm of thread is
available once the cover trims are fitted.
• Complete the pipework to the shower area
having decided on the position of the shower
and direction of pipe entry (for example
rising, falling or rear entry)
The hot and cold water pipes should be securely
attached within the wall or panel to support the
valve and prevent movement after installation.
THIS IS REQUIRED TO ALLOW THE
CORRECT FITTING OF THE MIXER VALVE.
Pipe fitting depth should be checked in
conjunction with the information given in
(fig.5) - a MINIMUM of 7mm of thread
MUST be available once the Straight Fitting is
secured into the wall end fitting and the cover
trim has been fitted. This is to allow the mixer to
be fitted correctly. Inlet pipe centres should be
approximately 150mm apart.

Thermostatic bar mixer shower
*STRAIGHT FITTINGS
Fig.5
The supply pipes can be routed from the side,
rising, rear or falling and must end in suitable
fittings (fig.5) to accept the long thread
connectors.
Appropriate
end fitting
The straight connectors can be used to connect
to ½” BSP female elbow fittings in solid wall
installations. The inlet centres on the shower
valves must be aligned horizontally and centred
to 150mm.
The hot and cold supply pipes MUST be
anchored rigidly to support the valve and stop
any movement after installation.
MAKING GOOD
• Make good the wall and complete the tiling.
Note: It is advised to use a suitable sealer around
the variable connector where it enters the wall to
stop water ingress (fig.6).

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.

MAINTENANCE
Cleaning
Maintenance of the unit is required to give
continued performance after installation and that
it continues to provide scald prevention.
It is recommended that all products are cleaned
using warm, soapy water.
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 TMV3 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.
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.
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 unit
from the inlet fittings.
• Remove the filter housing and disassemble.
• Wash the filters thoroughly under running
water, use a suitable brush to remove all debris.
• Reassemble and fit in reverse order.
Note: the filter
housing is Left
hand thread.
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.
‘O’ ring
Filter
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).
Filter housing
• 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.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement - please see
the spare parts list.

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.
WARNING!
DO NOT use ‘powerful’ abrasive or
solvent cleaning fluids when cleaning the
shower as they may damage the fittings.

Thermostatic bar mixer shower
IN SERVICE TESTING
With an acceptable mixed water temperature,
complete the following procedure:
Maintenance of the unit is required to give
continued performance after installation and that
it continues to provide scald prevention.
a) record the temperature of the hot and cold
water supplies
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.
b) record the temperature of the mixed water at
the largest draw-off flow rate
c) record the temperature of the mixed water
at a smaller draw-off flow rate, which shall be
measured
Purpose
d) isolate the cold water supply to the mixing
valve and monitor the mixed water
temperature
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.
e) record the maximum temperature achieved
as a result of (d) and the final stabilised
temperature
Procedure
f) record the equipment, thermometer etc.
used for the measurements
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:
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
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
c) record the temperature of the mixed water
at a smaller draw-off flow rate, which shall be
measured
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
Annex F of D 08 (informative)
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
18
Thermostatic bar mixer shower
FREQUENCY OF IN-SERVICE TESTS
General
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.

the back of the book for your use.

your details including post code, the model number and power
rating of the product, together with the date of purchase and, where
applicable, details of the particular fault.
2. If required, the Customer Service Advisor will arrange
for a qualified engineer to call.
3. All products attended to by a Triton service engineer must be
installed in full accordance with the Triton installation guide
applicable to the product. (Every product pack contains an
installation guide, however, they can also be downloaded free at
www.tritonshowers.co.uk).
4. Our engineer will require local parking and if a permit is required this
must be available to the engineer on arrival at the call.
5. It is essential that you or an appointed representative (who must
be over 18 years of age) is present for the duration of the service
engineer's visit. If the product is in guarantee you must produce proof
of purchase.
6. Where a call under the terms of guarantee has been booked and the
failure is not product related (i.e. scaling and furring, incorrect water
pressure, pressure relief device operation or electrical/plumbing
installation fault) a charge will be made. A charge will also be issued if
nobody is at home when the service engineer calls or adequate
parking/permit is not available.
7. If the product is no longer covered by the guarantee an up front fixed
fee will be charged before the site visit.
8. Should proof of purchase not be available on an “in-guarantee” call,
or should the service engineer find that the product is no longer
under guarantee, the engineer will charge the same fixed price and
the customer will be expected to pay the engineer before he leaves. If
payment is not made on the day an administration charge will be
added to the fixed charge.
9. If a debt is outstanding from a previous visit, or from any other Triton
purchase, Triton reserves the right to withhold service until the debt
has been settled.

or physically, Triton reserves the right to withhold service and will
support the employee with a legal prosecution.
