For safety reasons, take care of the drain/vent valves position
so that when the process fluid is removed during the drain/
vent operation it is directed down and away from technicians. It
is recommended to mount the transmitter to prevent this
possible source of damage for unskilled operators.

IMPORTANT
In case of a High Static differential pressure transmitter,
please notice that the Vent/Drain valves can be configured
only on the process axis (V1).
