APPROVALS
This mixer valve is approved to the requirements of:
*
BS EN 1111
*On pressures above 0.5 bar.
* WRAS
Designation:
HP-S
(high pressure shower only)
It is a requirement that all TMV2 approved valves shall be verified against the original set
temperature results once a year.
On installation and on a yearly basis please perform the following checks:
1. Cold water supply isolation test
Isolating the cold water supply to the TMV, wait for five seconds if water is still flowing check that
the temperature is below
46C
.
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.
If there is a residual flow during the commissioning or the annual check this is acceptable
providing the temperature of the water seeping from the valve is no more than
2C
above the
designated maximum mixed water outlet temperature setting of the valve.
Note:
Temperature readings should be taken at the normal flow 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.
