compressed air at the specified intervals (never
direct compressed air towards persons) paying
particular attention to:

Regulating elements

Fittings

Compressor block

Cooler

Electric motor

Danger
Only perform filter mat change after the
compressor system has been shut down and
depressurized!
a) Perform filter mat change as follows:

Remove mounting bolt (- 2 - Fig. 23).

Remove filter mat (- 1 - Fig. 23) and clean,
exchange if damaged.

Re-insert filter mat in the bottom access panel
(- 3 - Fig. 23).

Secure filter mat by means of the mounting bolt.
Cleaning:
Clean the filter mat by brushing or washing.
Important
Never install the filter mat in a wet or moist state!
b) Inlet filter and outlet filter of control cabinet
(only L07RS-L11RS):

Open the louvred grilles of the inlet filter
(-4- Fig. 23) and of the outlet filter (-5- Fig. 23).

Remove the filter pad.

Insert the new filter pad into the louvred grille.
Ensure that the smooth side (-A- Fig. 23) of the
filter pad faces the air inlet side.

Place the louvred grille back onto the filter
housing.
Changing times for the filter mat
The operating modes and the quality of the suctioned
air (e.g. dust content) has a strong influence on the filter
service life.
The filter should be checked on a weekly basis,
eventually daily basis, for dust build-up.
In these operational cases, shorter change intervals are
possible.
