9.3 Maintenance and inspection
schedule
Warning
When performing control, adjusting and
maintenance 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 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 L90RS-L132RS:
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!
Important
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
depressurised prior to any maintenance work by
slowly opening the lock (oil filler cap) with integral
vents

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.
For order numbers see the spare parts list.
