The mixed water temperature at terminal fitting should
never exceed 46ºC.
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.
Temperature readings should be taken at the normal flow
rate after allowing for 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
manufacturers' instructions.
Commissioning and in-service
tests
Commissioning
Purpose
Since the installed supply conditions are likely to be diffe-
rent from those applied in the laboratory tests it is appro-
priate, at commissioning, to carry out some simple checks
and tests on each mixing valve to provide a performance
reference point for future in-service tests.
Procedure
1.
Check that:
a) the designation of the thermostatic mixing valve
matches the intended application
b) the supply pressures are within the range of ope-
rating pressures for the designation of the valve
c) the supply temperatures are within the range per-
mitted for the valve and by guidance information
on the prevention of legionella etc.
2.
Adjust the temperature of the mixed water in accor-
dance with the manufacturer’s instructions (page
63) and the requirement of the application and
then carry out the following sequence:
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 measu-
red
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
NOTE: The final stabilised mixed water temperature
should not exceed the values in Table A.
f) record the equipment, thermometer etc. used for
the measurements
