Change inlet filter
1. Pivot open the louvred grille of the inlet filter.
2. Remove dirty filter.
3. Insert new filter.
4. Close louvred grille.
Replacement times for the inlet filter elements
The operating modes and the quality of the suction
air (e.g. dust content) have a significant impact on
the service life of the filter elements.
The filter elements should be inspected for dust
accumulation at least weekly; daily if possible.
If usage scenarios transpire with, for example, a
high rate of dust accumulation, the replacement in-
tervals must be shortened in relation to the main-
tenance plan.

WARNING
Risk of scalding
Risk of scalding by hot oil.
➯
Only change the oil when the com-
pressor is stationary and depres-
surised.
➯
Caution when draining hot oil.
Oil must be changed if the message [
Service due
]
is displayed on the electronic control unit.
With these compressors, the time for changing oil
is heavily dependent on the degree of soiling of
the circulating oil. It is vital you ensure that no oil-
harming foreign substances (dust, vapour, gas)
get into the oil circuit of the compressor system
through the air suction filter with the suction air.
Also, high humidity in the suction air and conden-
sate build-up within the machine have an impact
on the service life of the lubrication oil, meaning
that shortening of the oil replacement times may
be necessary. The replacement intervals specified
are based on suction air which is normally present
and no large ratios of foreign substances (dust,
vapour, gas) arising.
