5 Operating instructions
5.1 Initial start-up
Warning
The operator must apply all relevant Safety precautions.
Switch off the voltage before making any adjustment.
Outdoor/altitude operation
If the compressor is installed outdoors or if the air inlet temperature can be below freezing point, precautions
must be taken. In this case, and also if operating at high altitude, consult Atlas Copco.
Moving/lifting
The compressor can be moved by a lift truck using the slots in the frame. Make sure that the forks protrude
from the other side of the frame. The compressor can also be lifted after inserting beams in the slots. Make
sure that the beams cannot slide and that they protrude from the frame equally. The chains must be held parallel
to the bodywork by chain spreaders in order not to damage the compressor. The lifting equipment must be
placed in such a way that the compressor is lifted perpendicularly. Lift gently and avoid twisting.
General preparations for GA VSD compressors
Step Action
1 Install the compressor, see the sections Dimension drawing, Installation proposal and
Electric cable size.
2 Stick labels near the control panel to warn the operator that:
•
the compressor may start automatically after a voltage failure
•
the compressor is automatically started and stopped
•
the compressor may be remotely controlled
3 A number of VCI (Volatile Corrosion Inhibitor) plates are provided inside the bodywork to
protect the compressor against corrosion. Remove the plates.
4 If the compressor has not run for the past 6 months, it is required to improve the lubrication
of the compressor element before starting. Fill up the compressor element as described
in section Oil change (paragraph: Filling the compressor element with oil).
5 Check that the compressor is filled with oil; the pointer of the oil level indicator should be
in the green range (see the section Oil change).
