nents that may compromise proper unit operation.
For further information concerning alarms and operations, see the installed microprocessor operating manual.
12.1.2 MAINTENANCE ON THE AIR FILTERS
ATTENTION! DANGER!
Risk of immediate start-up after resetting the main switch if used as an emergency stop!
The main switch can be used as an emergency stop when the operator is near the machine (during start-
up, operation and maintenance). In this case, resetting the main switch will allow the machine to imme-
diately restart, without any additional action by the operator.
WARNING!
The lters are non-regenerable.
It is advisable to replace with original pieces only. Filters that do not conform to the original lters may
not be compatible with the unit performance and cause operating problems.
WARNING!
To guarantee the eciency of the lters, it is necessary to install
a 15 x 3 mm seal.
The Manufacturers air conditioners are equipped with, on all installed lters, dierential pressure sensors in order to mon-
itor pressure loss of the dirty lter. The microprocessor signals when the measured pressure dierence exceeds the set value. To
change the trip setting of a dierential pressure switch, simply unscrew the cover and turn the setting dial to the desired pressure
drop value.
