Please record the testing done during the commissioning and record the temperature of the hot and cold-water
supplies and the temperature of the mixed water at the full hot setting.
A calibrated digital thermometer having rapid response time with maximum temperature hold will be required
to check and set the outlet mixed temperature of the mixer.
To Commission
To test the temperature, open the valve and allow the mixed heated water to flow for at least 30 to 60 seconds
so the temperature can stabilise before taking a temperature reading at the outlet with a digital thermometer.
The flow rate should be at least 4L/min.
The temperature should be taken
close to the mixer’s outlet and if the outlet temperature requires adjustment
then follow the temperature adjustment in the installation instructions.
Shut Down Test
Once the correct outlet temperature has been achieved, the valves internal mechanism should be exercised at
least 3 times by alternately shutting off the hot and cold supplies while the mixer is set in the full hot position.
Shut Down Test 1
With the mixer still on and with both supplies turned on, allow the mixed water temperature to stabilise for at
least 15 seconds 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 reduce to be less than 0.1L/min following the isolation. Recording of the
temperature should continue after isolation and should not exceed the maximum temperature set out in 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. The time taken to stabilise the temperature
should not exceed the maximum time set out in the applicable standard or code of practice for each state.
Shut Down Test 2
With the mixer still on and with both supplies turned on allow the flow to stabilise for at least 15 seconds and
record the temperature. Quickly isolate the hot water supply to the valve.
