9.1 Maintenance recommendations
Note
The screw compressor unit can only operate to your
complete satisfaction when the maintenance work is
carefully carried out at the specified intervals.
In order to facilitate this task, the scope of supply of the
screw compressor unit comprises the “Maintenance and
inspection manual for CompAir compressors”, in which
you can list your performed maintenance work at the
specified intervals.
You can also have this maintenance work performed by
our trained technicians. Please ask your CompAir
distributor for a maintenance contract.
Only for AirStation L07FS-L11FS series:
Please refer to the enclosed operating instructions for
further information on maintenance.

9.2 Maintenance electric motor
The maintenance of the electric motor is to be

9.3 Maintenance and inspection
schedule
Danger
When performing control, adjusting and mainte-
nance work, be careful with hot surfaces of
machine parts.
Checks and maintenance work may only be carried
out when the following points are observed:
• Press the STOP button on the control panel and
wait until the screw compressor unit has come
to rest and the screw compressor unit is
depressurized
• The pressure display does no longer indicate
pressures < 0.3 bar/4.4 PSI.
• Shortly after switching the screw compressor
off, the system can contain a low residual
pressure.
• The screw compressor unit must therefore be
depressorized prior to any maintenance work by
slowly opening the lock (oil filler cap) with
integral vents
• The customer-installed main switch is set to "O"
(OFF) and locked off
• Warning:
Electrical voltage: Only work on the screw
compressor unit when it is disconnected.
• Only L07RS-L11RS and L07RS FS-L11RS FS:
Danger of electric shock from loaded
condensers!
Please always first disconnect the system from
the power supply and wait another 10 minutes
before touching the electrical components. The
power condensers require this time in order to
discharge!

Intervals are valid for normal industrial environments
and operating conditions. When in doubt, check the oil
change intervals by carrying out an oil analysis.
In the case of a very dirty atmosphere, the maintenance
intervals have to be shortened as required.
