Commissioning
5.3 Measure and record the temperature of the water discharging from the valve for the
largest and smallest draw off point.
5.4 Isolate the cold water supply to the valve and monitor the mixed water temperature.
5.5 Measure and record the maximum mixed water temperature and the final temperature.
The final temperature found during the test should not exceed the values quoted in
table 2.
5.6 Record all the equipment used during the commissioning.
6. Ensure that the application, to which the valve will be used, is appropriate for the approved
designation.
7. The above information must be recorded and updated on every occasion when any work is
carried out on the valve.
In Service Testing
To ensure that the Thermostatic Mixer maintains a high level of protection, we advise the following in
service testing is followed (the same equipment used to commission the valve initially must be used in
the following tasks).
1. After a period of between 6 and 8 weeks after commissioning carry out the following.
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 the smallest draw off flow rate.
2. If the mixed water temperature has changed significantly from the previous test results
(e.g. > 1 k), record the change and before re-setting the mixed water temperature check that:
a) All the strainers are clean
b) All the check valves are in good working order
c) The isolation valves are fully open.
