Commissioning
Upon completion of the installation, the valve should be tested and commissioned in
accordance with AS 4032.3 as per the procedure outlined below or as specified by the local
authority.
The following instructions should be read and understood prior to commissioning the Caleffi
5213TM series valve. If, under any circumstances, there are aspects of the installation/system
which do not comply with our requirements or the specifications as laid down, the valve must
not be put into service until the installation/system does comply.
1) Ensure that the system is throughly clean and free from debris prior to commissioning the
thermostatic mixing valve.
2) We recommend that the commissioning of temperatures are carried out using a suitably
calibrated and accurate digital thermometer.
The valve is commissioned by measuring the mixed water temperature at the outlet.
3) In accordance with the requirements of AS/NZS 3500, all new water installation shall deliver
hot water at the outlet of the sanitary fixtures used primarily for personal hygiene purposes
at a temperature not exceeding:
· 43.5°C for childhood centres, primary and secondary schools and nursing homes or
similar facilities for aged, sick or disabled persons and
· 50°C in all other classes of buildings
4) The temperature at the outlet of each valve must be set taking into consideration any
fluctuations which may occurr within the system due to simultaneous demand.
5) Once the supply temperatures are stabilised and the normal operating conditions are
established, the valve can be commissioned. Due to the unique design of the cap, the
temperature setting can be adjusted by removing the cap from the valve body and
reversing the cap onto the temperature adjustment spindle. We suggest that the following
sequence is followed when commissioning the valve.
a) Set the mixed water discharge temperature to the required temperature.
b) Measure and record the temperature of hot and cold water supplies at the connections to
the valve.
c) Measure and record the temperature of the water discharging from the largest and smallest
volume draw off points.
d) Perform the thermal shut-off test. Isolate the cold water supply to the Caleffi valve and
monitor the mixed water temperature. The outlet flow should quickly cease flowing.
e) Measure and record the maximum mixed water temperature. The temperature should not
exceed that allowed by the applicable standard or code of practice for each state.
f) Restore the cold water supply to the valve and measure and record the outlet temperature
after the mixed water temperature has stabilised. The final temperature found during this
test should not exceed the permitted 2°C.
6) Once the desired temperature has been reached, the adjustment spindle can be locked in
position using the locking nut supplied with the valve.
7) Once the desired temperature is established, remove the cap from the temperature
adjustment spindle and secure the head back on to the valve into its original position to
prevent tampering by unauthorised persons.
We recommend that the above information is recorded in the Commissioning Report and
updated on the Service Report when any work is carried out on the valve.
