In Service Testing
Purpose
The purpose of in-service tests is to regularly monitor and record the
performance of the thermostatic mixing valve. Deterioration in performance
can indicate the need for service work on the valve and/or the water
supplies.
Procedure
Using the same measuring equipment or equipment to the same
specification as used in the commissioning of the valve, adjust the
temperature of the mixed water in accordance with the manufacturer’s
instructions and the requirement of the application. Carry out the following
sequence:
a) Record the temperature of the hot and cold water supplies.
b) Record the temperature of the mixed water at the largest draw-off flow
rate.
c) Record the temperature of the mixed water at a smaller draw-off flow
rate, which shall be measured if the mixed water temperature has
changed significantly from the previous test results (e.g.> 1 K), record the
change and before re-adjusting the mixed water temperature check:
a)
That any in-line or integral strainers are clean.
b) Any in-line or integral check valves or other anti-back siphonage devices
are in good working order.
c) Any isolating valves are fully open
