10.1 Maintenance recommendations
NOTICE
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
Gardner Denver 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 Gardner Denver distributor for a
maintenance contract.
10.2 Maintenance Electric Motor
The maintenance of the electric motor is to be
performed in line with the motor operating instructions.
The drive motor is permanently lubricated.
10.3 Maintenance and inspection
schedule
DANGER
High voltage – Hazard of shock, burn, or
death
•
Be careful with electricity: only work on
screw compressors which are not
powered.
•
Only for L30RS-L45RS: There is a risk of
electric shock from charged capacitors!
Disconnect the system from the mains
and wait 10 minutes before touching
electrical components. The power
capacitors need this time to discharge.
WARNING
Some parts of the system will still be
pressurized after the system has been
switched off. Small parts propelled at high
speed by compressed air can penetrate the
skin or destroy an eye.
Only perform checks and maintenance after
observing the following:
•
Press the STOP button on the control
panel and wait until the screw
compressor comes to a stop and the
screw compressor unit is depressurized.
•
The pressure gauge shows no more than
< 4.4 PSI.
•
Shortly after shutting off the screw
compressor unit a small residual
pressure may remain.
•
Therefore, before any maintenance work,
the screw compressor unit must be
relieved by slowly opening the screw
plug (oil filling opening) with integrated
air vent slots.
•
Set the on-site main switch to “0” (OFF)
and secure it against being switched on.
CAUTION
Burn hazard – Hot surfaces
•
Be careful of the hot surfaces of machine
parts when carrying out checks, making
settings and doing maintenance.
Intervals are valid for normal industrial environments
and operating conditions. If there is some uncertainty,
set the oil change interval by performing oil analysis.
In the case of a very dirty atmosphere, the cleaning
intervals have to be shortened as required.
For order numbers see the spare parts list.
