Affix the above sheet, explaining the procedure for checking the motor rotation direction, to the cooling
air outlet of the compressor. Consult section
Switch on the voltage. Start the compressor and stop it immediately. Check the rotation direction of
drive motor (M1) while the motor is coasting to a stop.
Check the rotation direction of the motor. If the motor rotation direction is correct, the sheet on the top
grating will be blown upwards. If the sheet remains in place, the rotation direction is incorrect.
If the rotation direction of the drive motor is incorrect, open the isolating switch and reverse two incoming
electric lines.
Incorrect rotation direction of the drive motor may cause damage to the compressor.
- Check the programmed settings. Consult section
- Start and run the compressor for a few minutes. Check that the compressor operates normally.
