1. Assemble the Temperature handle to the Thermostatic cartridge.
2. Using the handle rotate anti-clockwise until the Handle temperature stop meets the Cartridge temperature stop and will
not turn anymore anti-clockwise. This is the maximum hot water temperature -
The maximum temperature should not
exceed 41°c.
3. To adjust the maximum temperature - Remove handle, re-position the Handle temperature stop by rotating the handle,
re-fit handle and turn to stop position, re-test.
If using for a Bath filler see
IMPORTANT
page for advised maximum temperatures.
Commissioning notes for Thermostatic Mixing Valves, please check the following
(a) The designation of the Thermostatic Mixing Valve matches the application. (b) The supply pressures are within the valve
operating range.(c) The supply temperatures are within the valve operating range. (d) Isolating valves are fitted.
If all these conditions are met set the temperature as per installation instructions.
It is a requirement that all TMV2 approved valves shall be verified against the original set temperature results once a
year. When commissioning/testing is due the following performance checks should be done.
Measure the mixed water temperature at the outlet. Carry out the cold water supply isolation test by isolating the cold
water supply to the TMV, wait for five seconds if water is still flowing check that the temperature is below 46°C. If there
is no significant 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.
Notes;
If there is a residual flow during the commissioning or the annual verification (cold water supply isolation test)
then 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. Temperature should be taken at normal flow
rate after allowing for the system to stabilise. The sensing part of the readings thermometer probe must be fully
submerged in the water that is to be tested. Any TMV that has been adjusted or serviced must be re-commissioned and
re-tested in accordance with the installation instructions. The installation of the thermostatic mixing valve must
comply with the requirements of the Water Supply (Water Fittings) Regulations 1999.
