COMMISSIONING THE TMV
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. Use the
“Commissioning Report” form at the back of this manual.
The following instructions should be read and understood prior to commissioning the Caleffi
2522TM 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 thoroughly 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 installations shall deliver
hot water at the outlet of the sanitary fixtures used primarily for personal hygiene purposes
at a temperature not exceeding:
a) 45°C for general Health applications;
b) 43.5°C advisable for childhood centres, primary and secondary schools and nursing
homes or similar facilities for aged, sick or disabled persons and
c) 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 occur 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.
6. Turn OFF the warm water ring main circulator(s) and close the isolation valve on at least one
(1) side of the circulator(s).
7. Close the hot and cold isolation valves on all TMV’S (if applicable) except the one which is to
be adjusted.
8. Open the warm water outlet nearest to the Warm Water System so that a flow rate of
approximately 8 litres per minute is achieved.
9. 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 the water discharging from the warm water
outlet and ensure the required blend temperature is achieved.
c) Measure and record the temperature of hot and cold water supplies at the
connections to the valve.
d) Measure and record the temperature at the TMV test point in the warm water unit
for the appropriate valve.
e) Create a higher flow rate that corresponds to maximum design flows by opening
additional outlets. Measure and record the temperature at the TMV test point for
the appropriate valve.
