Commissioning
The pipes must be flushed thoroughly before
commissioning a JRGUMAT LF thermostatic mixing
valve. When the installation is commissioned, the
mixing valve is ready for use.
Maintenance
JRGUMAT LF thermostatic mixing valves require no
maintenance. No attempts should be made to
repair JRGUMAT LF thermostatic mixing valves.
Malfunctions
If your JRGUMAT LF thermostatic mixing valve mal-
functions at any time, please contact your plumber.
Compare the installation with the examples. Check
whether the required blended water temperature is
not attained when enough is removed or whether
the temperature fluctuates when idle. In this case,
the circulation has not been adequately adjusted.
For further useful tips on possible causes and
their elimination, please refer to the document
"JRGUMAT Trouble shooting", which is available in
the download area of our homepage www.gfps.com.
