the Commissioning test sequence detailed above. If
the final mixed water temperature is greater than the
values in Table 3 and/or the maximum temperature
exceeds the corresponding value from the previous
test results by more than about 2°C the need for
service work is indicated (see TMV servicing and
cleaning instructions).
In-service tests should be carried out with a frequency
which identifies a need for service work before an
unsafe water temperature can result.
Frequency of in-service testing
6 to 8 weeks after commissioning carry out the test
sequence detailed above.
12 to 15 weeks after commissioning carry out the test
sequence detailed above.
Depending on the results obtained, the following
course of actions must be followed:
After correct commissioning secure the protective cap
using the supplied screw. The Bulldog TMV model is
supplied with two protective caps. One blue TMV 3 cap
and one white TMV 2 cap. Ensure that the blue colour
TMV 3 cap is fitted as this will indicate the valve has
been commissioned to the TMV 3 standard.
•

•
•
In Service Testing (TMV 3)
The purpose of in-service testing 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 water supplies.
Carry out the test sequence detailed below using
the same or equivalent equipment as used for
commissioning the valve.
•
•
•
•
Check the designation of the thermostatic valve matches the application.
Check that the supply pressures and temperatures are within the operating range of the valve.
Check that the supply temperatures are within the range permitted for the valve and by guidance
information on the prevention of legionella etc
Check there have been no significant changes in inlet supply temperatures and pressures since
commissioning or the previous in service test.
If significant changes have occurred it is
recommended to re-commission the valve.
If the mixed water temperature has changed
significantly from the previous test results (e.g.>1°C),
record the change and before re-adjusting the mixed
water temperature carry out the following checks;
•
•
•
If no significant changes (e.g.<1 °C) in mixed
water temperature are recorded between commissioning and testing at 6 to 8 weeks, or between commissioning and testing at 12 to
15 weeks, the next in-service test can be deferred to 24 to 28 weeks after commissioning.
If small changes (e.g.1 to 2 °C) in mixed water temperature are recorded in only one of
these periods, necessitating adjustment of the mixed water temperature, then the next inservice
test can be deferred to 24 to 28 weeks after commissioning.
If small changes (e.g.1 to 2 °C) in mixed water temperature 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.
If significant changes (e.g. >2 °C) in mixed water temperature are recorded in both 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 test 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.
It is recommended that In-Service Tests are carried out once every 6 months as a minimum.
Note:
All in-line or integral strainers are clean
Any in-line or integral non-return valves or other anti-backsiphonage devices are in good working order.
Any isolation valves are fully open.
5
If there is a residual flow during the commissioning or in
service test during the cold water supply isolation test
then this is acceptable providing the temperature of the
water seeping from the valve is no more than 2°C above
the designated maximum mixed water outlet temperature
setting of the valve as defined in Table 2.
Temperature readings should be taken at the normal flow
rate after allowing the system to stabilise. The sensing
part of the thermometer probe must be fully submerged
in the water that is to be tested.
The mixing valve is supplied with filter elements but
it is advisable to additionally install Y-strainers on the
hot and cold water supplies. The isolating valves and
strainers should be installed as close as practicable to
the location of the mixing valve and should always be
in an accessible location.
Any TMV that has been adjusted or serviced must be
re-commissioned and re-tested in accordance with the
manufacturer’s instructions.
Before installation, the hot and cold water supply
systems must be thoroughly flushed to remove any
dirt/debris that may have accumulated. Failure to do
so may adversely affect the performance of the mixing
valve.

The above temperatures are recommended by the Thermostatic Mixing Valve (manufacturers) Association
as relevant settings for the varying applications shown. This is the maximum commissioning temperature
but valves may exceed this by 2°C in use.
The range of available temperature adjustment is 35°C to 48°C but
46°C is the maximum recommended mixed water temperature from a bath tap. The maximum temperature
takes account of the allowable temperature tolerances inherent in thermostatic mixing valves and temperature
losses in metal baths.

to the correct application temperature by turning the
spanner counter clockwise. If the valve overshoots this
temperature, return the valve to the full cold
condition, and reset it to the correct temperature
+0-2°C. Do not set a valve on a lowered temperature
as this will not provide consistent operation.
The British Burns Association recommends 37°C 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.
Remove the plastic protective cap on top of the valve with the supplied Allen key or other suitable
tool.
COMMISSIONING (TMV 2)
The valve must be commissioned under normal site
system conditions and after establishing supply
conditions with the hot and cold water supplies open,
leave the system running to allow temperatures and
pressures to stabilise and be checked.
When the valve is set to the required temperature for
the application carry out 5 cold water isolation tests
to further exercise the valve.
•
Prior to commencing commissioning, the following
checks should be carried out.
•
•
•
The designation of the thermostatic mixing valve matches the application.
The supply pressures and temperatures are within the operating range of the valve.
Isolating valves and strainers are provided.
If all these conditions are met, proceed to set the temperature as described below.
Set the mixed water temperature to the required value. It is advisable to use a calibrated digital
thermometer for checking the inlet and outlet temperatures.
• Measure and record the temperature of the hot and cold water supplies at the inlets to the valve.
• Measure and record the temperature of the water discharging from the valve at the greatest draw-off
flow rate.
• In the absence of other temperatures being specified those detailed in Table 5 are the desired settings.
The Bulldog TMV thermostatic mixing valve is supplied
factory set at 43°C but the valve may be simply
adjusted after installation.
The set mixed water temperature at the terminal
fitting must never exceed 46°C
Once the required mixed outlet temperature has been
achieved, isolate the cold water supply and monitor
and record the mixed water temperature including the
maximum and final temperatures achieved. The mixed
water temperature should never exceed 46°C.
• Remove the plastic protective cap on top of the valve with the supplied Allen key or other suitable
tool.
8
Isolate the cold water supply and RECORD the
maximum temperature achieved. After 5 seconds, if
water is still flowing RECORD the temperature of the
flow. Restore the cold water supply and RECORD the
stabilised mixed water outlet temperature.
After correct commissioning secure the protective cap
using the supplied screw. The Bulldog TMV is supplied
with two protective caps. One blue TMV 3 cap and one
white TMV 2 cap. Ensure that the white colour TMV 2
cap is fitted as this will indicate the valve has been
commissioned to the TMV 2 standard.
•
If there is no significant change to the stabilised set outlet temperature (±2°C or less deviation from the original setting) and the fail safe shut-off is functioning, then the valve is working correctly and no further service work is required.
• If the maximum mixed water temperature exceeds the previous test results by more than 2°C then the
need for service work on the valve is indicated.
• The equipment used in these In-Service Tests should be RECORDED and should preferably be the same as that used at installation.
Note:
Record all the equipment used during commissioning.
If there is a residual flow during the commissioning
or the annual verification (cold water supply isolation
test) then this is acceptable providing the temperature
of the water seeping from the valve is no more than
2°C above the designated maximum mixed water
outlet temperature setting of the valve (See Table 5).
In Service testing (TMV 2)
The Bulldog TMV thermostatic mixing valve will
provide satisfactory service and a high level of
protection, provided it is maintained and subjected
to In-Service Testing.
Temperature readings should be taken at the normal
flow rate after allowing the system to stabilise. The
sensing part of the thermometer probe must be fully
submerged in the water that is to be tested. Any TMV
that has been adjusted or serviced must be
re-commissioned and re-tested in accordance with the
manufacturer’s instructions.
Approximately 6-8 weeks after commissioning, the
following tests should be undertaken.
•
•
•
Check the temperature of the hot and cold water supplies - RECORD
Check the temperature of the mixed water
temperature at the greatest draw off flow rate – RECORD
Check there have been no significant changes in inlet supply temperatures and pressures since
commissioning or the previous in service test.
If significant changes have occurred it is
recommended to re-commission the valve.
In the absence of any other instruction or guidance,
it is recommended that In-Service Tests are carried
out once every 12 months as a minimum. If the
temperature is outside of the expected range it will be
necessary to remove and clean the valve in accordance
with the following instructions.
TMV Cleaning and Servicing Instructions
(TMV 2 & TMV 3)
If the mixed water temperature has significantly
changed from that measured at installation
(e.g. > 1°C), RECORD the change and before making
any adjustments to the valve confirm that:-
Most domestic water supplies contain calcium which
will separate out when the water is heated in a
system. The degree and speed of scaling may vary
depending on factors such as water flow rates,
system design, the hardness of the water and the
temperature to which the water is heated.
Deposits of scale may over time form in the valve,
particularly at the hot inlet. The formation of the
scale may adversely affect the performance of the
valve which will be detected during the in-service
testing. If this occurs it will be necessary to remove
the valve for de-scaling and servicing.
• Strainer elements in the hot and cold water supplies
are clean and undamaged.
• Non-return valves are clean and operating correctly.
• Isolation valves are operating correctly and are set in the fully open position.
If the mixed water temperature is acceptable, the
following additional observations should be made:9
• Isolate the hot and cold supply.

• Remove the valve to a clean working area.
• Remove the protective cap.
• Unscrew the headwork of the valve.
• Carefully remove the element and valve assembly and put to one side.
