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.
9.2
Maintenance electric motor
The maintenance of the electric motor is to be
performed in line with the motor operating instructions.
9.2.1
Motor lubrication system
The screw air compressor unit
ʼ
s drive motor is fitted
with an automatic motor lubrication system.
Function of the motor lubrication system
The automatic motor lubrication system ensures that
the motor mounting is lubricated at all times. The
installed lubricators are powered (24 V DC) via the
compressor control when the drive motor is running.
The volume of grease set on the lubricator is dispensed
over several cycles depending on the motor runtime
measured.
An empty LC unit or a fault on the lubricator is indicated
on the compressor control by means of a message
[Warning: Mot.lubr. sys] (also refer to the operating
instructions for the compressor control DELCOS XL).

Changing the LC unit
An empty LC unit or a fault on the lubricator is indicated
on the compressor control by means of a message
[Warning: Mot.lubr. sys] (also refer to the operating
instructions for the compressor control DELCOS XL).
Important
Regularly check the level of grease in the
transparent LC unit.
The red and green LEDs will light up
simultaneously to indicate when the empty LC unit
needs replacing. This indication will only appear
when the screw air compressor unit
ʼ
s drive motor
is running.
The drive system and control plate must be
protected from dampness.
