1. Measure & record supply temperature and
pressures, if possible (see Commissioning 4.2(a)).
2. Measure & record blend temperature & flow rate
@ maximum flow (see Commissioning 4.2(b)).
3. Measure & record blend temperature & flow rate
@ minimum flow (see Commissioning 4.2(c)).
Has mixed water
temperature changed by
more than 1K?
No
8. Ensure supply temperatures & pressures and flow
rate at time of test are within valve specification (see
Operating Parameters). Record all these.
9. Isolate CW supply (see Commissioning 4.2(d)).
10.Measure & record max & final blend temp. (see
Commissioning 4.2(e)).
Is max. Blend temp. >2K
above previous recorded
value?
No
Is final blend temp.
>2K above set blend temp?
No
Note! K = Kelvin, the unit of thermodynamic temperature. The unit "Kelvin" is equal
to the unit of "Degree Celsius". Kelvin is used for a difference of Celsius
temperature.
