Maintenance and service 8
January 2017 America 51 /72
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, heavy moisture content in the suction air and
condensation build-up within the machine have
an impact on the service life of the lubrication oil,
meaning shortening 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.
When changing oil, drain used oil as completely as
possible, as used oil greatly reduces the service
life of the new oil charge.
You must refrain from mixing different lubrication
oils. When changing oil types, the oil must be
completely drained from the oil circuit.
You can find the maintenance intervals in the
maintenance plan.
Replacement times for the lubrication oil
Operating conditions (e.g. cooling medium
temperatures), the type of operation and the
quality of the suction air (e.g. dust content, content
of gaseous foreign substances such as SO2,
solvent vapours, etc.) have a significant impact on
oil change intervals.
In such instances of usage, the permitted duration
of use of the oil must be checked with the help of
an oil analysis.
NOTE
Collect the used oil. Do not let it drain into the
soil.
Dispose of the oil in accordance with
regulations. Do not discard any oil. Immediately
capture any used oil! Ensure leak-tightness!
Changing oil
1
Lockout and Tagout.
2 Wait for compressor to cool down
3 Open the enclosure, create access.
4 Open oil filler neck carefully. Allow any
residual pressure to be released.
5 Provide an oil collecting vessel.
6 Place oil drain hose over the collecting vessel.
7 Open oil drain valve.
8 Drain oil completely.
9 Close oil drain valve.
10 Top up with oil until the max. mark is reached.
11
Shut oil filler neck.
12
Close the enclosure.
13
Switch on the main disconnect switch.
14
Switch on screw compressor for approx. 2 min.
15
Switch off screw compressor.
16
Switch OFF the main disconnect switch and
secure it against switching on again.
17
Open the enclosure.
18
Check the oil level. If necessary, correct oil
level.
19
Close the enclosure.

WARNING
Scalding hazard
Scalding hazard from hot oil.
➯
Change the oil only when the
compressor is stopped and not
pressurized.
➯
Use caution when draining out the
hot oil.
The compressor is equipped with two oil filters.
The oil filter elements must be changed, if the
message [
Service due
] or [
Oil filter
] is displayed
on the electronic control unit.
Replacing oil filter elements
1
Switch OFF the main disconnect switch and
secure it against switching on again.
2 Wait for compressor to cool down
3 Open the enclosure, create access.
