Commissioning

Important:

-  The following instructions must be read and understood prior to commissioning the

    thermostatic shower valve. If under any circumstances there are aspects to the installation / 
    system which do not comply with the specification laid down, the valve 

MUST NOT

be put

     into operation until the system / installation complies with the specification. However if all 
    these conditions are met, proceed to set the temperature as follows;

   1.  Ensure that the system is thoroughly cleaned and free from any debris prior to 
        commissioning the thermostatic shower valve.

   2.  Commissioning the temperatures must be carried out using a suitably calibrated 
        thermometer, preferably a digital thermometer. The sensing part of the thermometer probe 
        must be fully submerged in the water when testing.

   3.  The 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 shower valve are open during setting of the mixed 
        water temperature. It is advisable to ensure that the water temperatures are established 
        before any attempt to commission.

   4.  Once the supply temperatures are stable and the normal operating conditions are 
        established, the shower valve can be commissioned. The following sequence should be 
        followed when commissioning the valve;

        4.1 The first step in commissioning a thermostatic shower valve is to check the following:

• The designation of the thermostatic shower valve matches the application

• The supply pressures are within the valve’s operating range.

• The supply temperatures are within the valve’s operating range.

• Isolating valves (and ‘Y’ strainers preferred) are provided.

        4.2 If all these conditions are met, proceed to set the temperature following the procedure 
        

described earlier in the Calibration section. 

        4.3 Measure and record the temperature of the hot and cold water supplies at the 
        

connection to the valve.

        4.4 Measure and record the temperature of the water discharging from the valve. 

        4.5 Isolate the cold water supply to the valve and monitor the mixed water temperature.

        4.6 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.

        4.7 Record all the equipment used during the commissioning.

        4.8 The mixed water temperature at the terminal fitting must never exceed 2˚C above the 
        

set temperature.
