Install a new fine oil separator.
·
Pivot the reservoir cover back to the starting
position.

Screw the cheese-head screws (- 8 - Fig. 20)
counter-clockwise until the reservoir cover is lying
loosely on the pressure reservoir flange
·
Screw in and tighten crosswise all hex. screws
except for the two screws in the pivot area of the
PMV.

reservoir cover (- 8 - Fig. 20) for rotary protection
(clockwise).
·
Properly reinstall all lines to the pressure reservoir
and the oil extractor which have been removed.
Changing times for the fine oil separator
Operating conditions (e.g., coolant temperatures), the
type of operation and the quality of the intake air (e.g.,
dust content, ratio of gaseous foreign substances such
as SO
and solvent vapors) have a strong influence on
2
the filter lifespan (air filter, oil filter, fine separator).
In these cases the intervals between changes may be
shorter

10.7 Change of air intake filter

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!
NOTICE

1 Air intake filter
2 Intake filter monitor (visual)
As a standard, the air filter is provided with a visual in-
take filter monitor (-2- Fig. 21), 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 10.1. 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
substances such as SO and solvent vapors, etc.) have
2
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.
