3 OPERATING INSTRUCTIONS
Safety precautions
The operator must apply all related safety precautions including
those mentioned in this book.
Outdoor/altitude operation
If the compressor is installed outdoors or if the air inlet
temperature can be below 0°C (32°F), 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 will be lifted
perpendicularly. Lift smoothly and avoid twisting.
3.1 Preparation for initial start-up
1. Consult section 2 for the electric cable size, installation
proposal and dimension drawings.
2. Read the "User manual for Elektronikon
®
regulator" to
familiarize yourself with all regulator functions.
3. A sticker dealing in short with the operation instructions
is delivered with the literature set. Affix the sticker next
to the control panel.

that:
- the compressor may automatically restart after voltage
failure
- the compressor is automatically started and stopped
- the compressor may be remotely controlled
See section 1.2.
5. The gear casing supports and motor support are secured
to the frame, immobilizing the vibration dampers during
transport. Remove stud and nuts (3-Fig. 11a) of both gear
casing supports as well as bushes (1-Fig. 11b) of the motor
support.
6. Check the wires at transformer (T1-Fig. 2) for correct
connection, the settings of overload relay (F21) and circuit
breakers (Q15/16) 1), and that overload relay (F21) is set
for automatic resetting (indicated on the relay by "A").
