OPERATION
(AUTO MODE)
This procedure assumes that the pneumatic system is checked and set accord-
ing to AOM 16.2 PNEUMATICS.
Running a recirculation fan creates heat around the fan itself.
If a recirc fan is running (on ground) without the corresponding ACM more than
approx. 10 minutes (depending on OAT) a thermo switch will turn off the fan for a
considerable time until the temperature has decreased and the thermo switch au-
tomatically resets.
