Procedure:
1. Unscrew the cover from the
pressure switch.
2. As long as the plant exhaust
system is switched on, the air

pressure capsule must be read-
justed.

capsule and check to see
whether or not the exhaust
alarm is displayed in red. If no
alarm is displayed, the pressure
capsule must be adjusted.
4. Reconnect the tube.
