Servicing and maintenance schedule
Danger
.
When carrying out control, adjusting and mainte-
nance work, be careful with hot surfaces of machine
parts.
Checking and maintenance work may only be car-
ried out when :
• Press the OFF-key on the control panel and wait
until the screw compressor unit has come to rest;
• the screw compressor unit is depressurized,
• the pressure display does no longer indicate pres-
sures < 0.3 bar.
• Shortly after switching the screw compressor off,
the system can contain a low residual pressure.
• The screw compressor unit must therefore be un-
loaded prior to any maintenance work by slowly
opening the plug (oil fill port) with integral venting
bore.
• The customer-installed main switch is set to "O"
(OFF);
• Warning : Electrical voltage:
Only work on the screw compressor unit when it
is disconnected.
8. Servicing and maintenance
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.
The operating hours stated herein are recommended
maintenance intervals for average operating condi-
tions. Depending on the intake conditions, the operat-
ing times may differ.
You can also have this maintenance work performed
by our trained technicians. Please ask your technical
adviser for a maintenance contract.
