1.3 Notes on possible property damage
NOTICE
!
Incorrect control due to the formation of ice on the regulator.
Medium temperatures below 0 °C may cause ice to form on the regulator, depending
on the air humidity. This may affect, in particular, the functioning of the plug or dia-
phragm stem guide.
Î
Prevent the formation of ice by taking appropriate precautions (e.g. enclosure,
trace heater etc.). The plant operator is responsible for selecting and implementing
appropriate precautions. See section 5.4.3.
