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. As a guide the
flow should be less than 0.2 litre/min following the isolation.
Monitor the maximum outlet flow temperature, record this on
the Commissioning Report (page 20). 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 - as a guide typically less than 0.4 litre/
min@500kPa down to less than 0.2litre/min@100kPa following
the isolation. Restore the hot water supply to the valve and
measure and record in the Commissioning Report (page 20)
the outlet temperature after the mixed water temperature has
stabilised ensuring the outlet temperature has re-established.
• Ensure that all details of the Commissioning Report are
completed & signed by the relevant signatories & 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.
