It is a requirement that all TMV2 approved valves shall be veried against the original set
temperature results once a year.
On installation and on a yearly basis please perform the following check.
1. Cold water supply isolation test.
Isolate the cold water supply to the TMV, wait for ve seconds if water is still owing check that
the temperature is below 46°C.
If there is no signicant change to the set outlet temperature (±2°C or less change from the
original settings) and the fail-safe shut off is functioning, then the valve is working correctly and
no further service work is required.
If there is a residual ow during the commissioning or the annual check, this is acceptable
providing the temperature of the water seeping from the valve is no more than 2°C above the
designated maximum mixed water outlet temperature setting of the valve.
NOTE:
Temperature readings should be taken at the normal ow rate after allowing for the system to stabilise.
The sensing part of the thermometer probe must be fully submerged in the water that is to be tested.
