Danger
Only perform checks and carry out work on the
screw compressor when the unit is out of
operation, depressurized, and secured from being
switched on again!
Important
Never operate the screw compressor unit without
the air filter (even a short operating time without
this filter can result in considerable damage to the
machine)!
As a standard, the air filter is provided with a visual in-
take filter monitor, which indicates clogging of the air
filter cartridge.
When the red service field of the intake filter monitor is
visible and remains clicked into position while the screw
compressor is out of operation, replace the air filter
cartridge.
However, the air filter cartridge should be replaced at
the latest as specified in chapter 9.3. Check air filter at
least once a week or, if required, daily for the accu-
mulator of dust. When carrying out maintenance work,
make sure that no dirt gets to the clean air side of the
air filter.
Changing intervals for air filter cartridge
The operating conditions (e.g. coolant temperatures),
the operating modes and the quality of the intake air
(e.g. content of dust, content of gaseous foreign matter
such as SO
2
, solvent vapours, etc.) have a strong
influence on the service life of the filters (air filters,
water filters, fine separators).
Where such conditions exist the filter element may
require changing more frequently.
Change the air filter as follows:
•
Pull snap latch outward and remove housing base.
•
Detach air filter cartridge while slightly turning it.
•
Carefully insert new air filter cartridge in the housing.
•
Close air filter with housing base. The snap latches
must click into position.
