MAINTENANCE
Thermostatic Mixing Valves are precision products and as such any maintenance needs to be undertaken in
e n env r nment nd n rd n e w th the m nuf turer’s nstru t ns
The purpose of servicing regularly is to monitor any changes in performance due to changes in either the
system or the product. This may highlight the need to adjust either the supply system or the product. These
products should be checked at 6 to 8 weeks and again at 12 to 15 weeks after commissioning. The results
are to be compared against original commissioning settings.
If there are no significant changes at the mixed temperature outlet then a 6 monthly servicing cycle may be
adopted. Otherwise, servicing checks should be carried out more frequently (e.g. every 4 months).
Follow the recommended maintenance procedures detailed in this section.
During servicing, note the following:
1. Repeat the procedure of recording and checking supply temperatures. (The same type of measuring
equipment should be used)
2. If the temperature has changed significantly from the previously recorded values, the following should
be checked:
a. All integral valve filters are clear of obstruction.
b. All integral check valves are clean and working properly to prevent backflow.
c. Any isolating valves are fully open.
d. The thermostat is free of debris.
When satisfied with the mixed outlet temperatures re-record the temperatures.
