The equipment is designed to provide a warning
if the air flow is obstructed.
Provoke an air flow stoppage by gripping the top
part of the bag or by shutting off the flow meter
outlet. The fan unit should then initiate alarms
by sound, light and vibrations. In usage of
compressed air the control valve SR 348 will
warn by sound.
If necessary, adjust the head harness. There are
a lot of adjustment options, see fig. 11. To adjust
the head harness easier, remove the head
harness from the face shield, see “To change the
head harness”.
