Commissioning
IMPORTANT – The following instructions must be read and understood prior to the commissioning
of a Thermostatic Mixer. If under any circumstances there are aspects to the installation/system which
do not comply with the specification laid down, the valve MUST NOT is put into operation until the
system/installation complies with our specification.
1. Ensure that the system is thoroughly cleaned and free from any debris prior to the
commissioning of the valve. (See page 13)
2. The commissioning of the temperature must be carried out using a suitably calibrated
thermometer – preferably a digital thermometer. (See page 10)
3. In the absence of other temperatures being specified we recommend that the outlet
temperatures quoted in table 1 are used, extracted from the "National Health Service –
Health Guidance Note – Safe Hot Water and Surface Temperatures".

4. Each valve must be commissioned taking into consideration any fluctuations, which may
occur within the system due to simultaneous demands. It is advisable that any outlets which
are connected to the same supply as the mixing valve are opened during setting of the
mixed water temperature. It is advisable to ensure that the water temperatures are
established before any attempt to commission.
5. Once the supply temperatures are stable and the normal operating conditions are
established, the valve can be commissioned. We suggest that the following sequence is
followed when commissioning the valve:
5.1 Wave your hand in front of the sensor to activate the tap, the mixed water temperature
should be preset (see page 8).
5.2 Measure and record the temperature of the hot and cold water supplies at the
connections to the valve.
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.
