2.4.1 Compressed air shut-off valves
The compressed air shut-off valve
on the air maintenance unit (see
Fig. 2) interrupts the air supply for
the unit.
Furthermore, the unit is equipped
with a further compressed air shut-
off valve for interrupting the air
supply to the container ventilation.

installed on the unit is identical:

rying out maintenance and repair work, you must always carry out complete
pressure release!
