Step Action
6 Check the oil level. The oil level should reach the bottom of the oil filler neck (FC).
Minimum level should reach the oil sight glass (GI) when the compressor is stopped.
If needed, top up the oil.
Take care that no dirt drops into the oil system.
Refit and tighten the filler plug (FC).
7 Provide labels, warning the operator that:
• The compressor may automatically restart after voltage failure (if activated, consult Atlas
Copco).
• The compressor is automatically controlled and may be restarted automatically.
• The compressor may be remotely controlled.
8 Check the rotation direction of the fan motor. For this purpose, a sheet is fixed to the top
grating of the compressor.
1. Switch on the voltage.
2. Start the compressor and stop it immediately.
If the rotation direction is correct, the sheet will be blown upwards. If the sheet remains in
place, the rotation direction is incorrect.
3. If the rotation direction is wrong, open the isolating switch in the voltage supply line and
reverse two incoming electric lines.
4. Remove the label.
