COMMISSIONING OF THE VALVE
SHUT DOWN TEST
Now that the mixing valve has been set and locked it is
necessary to perform a shut down check. Allow the mixed water
temperature to stabilise and note the outlet temperature. While
holding a digital thermometer in the outlet flow, quickly isolate
the cold water supply to the valve. The outlet flow should quickly
cease flowing. The flow should be less than 0.1L/min following
the isolation. Monitor the maximum outlet flow temperature,
and record this on the Commissioning Report. The temperature
should not exceed that allowed by the applicable standard or
code of practice for each state. Restore the cold water supply
to the valve. After the mixed water temperature has stabilised
note the outlet temperature ensuring the outlet temperature has
re-established.
Repeat the above test, except this time quickly isolate
the hot water supply to the valve. The outlet flow should quickly
slow to a trickle. The trickle should typically be less than 0.4L/
min@500kPa down to less than 0.1L/min @100kPa following the
isolation.
Restore the hot water supply to the valve. After the mixed water
temperature has stabilised, measure and record the outlet
temperature, ensuring the outlet temperature has re-established.
Ensure that all details of the Commissioning Report are
completed and signed by the relevant signatories, and a copy is
kept with the installer and owner of the premises.
The valve is now commissioned and it can be used within
the technical limits of operation.
