Installation and operation
5.1.10 Direction of rotation
Check the direction of rotation of the main motor when
starting the compressor for the first time. You do this by
switching on the compressor and switching it off within 5
sec. Press the green start button to power on and the red
mushroom stop button to power down the compressor.
The motor must rotate in the clockwise direction when
viewed from the main motor cooling fan side. If the
direction of rotation is not correct, isolate the machine
from the electrical lines and interchange any two phases.
Restart the compressor and ensure that the direction of
rotation of the main motor is counterclockwise and the fan
motor is clockwise.
Switch on the compressor after ensuring all the above
points and let it run at the rated speed.
In case of problems during the compressor operation, note
the fault message in the controller display of the
compressor. Refer to the Functional Description and
Operation sections of this manual to know more about the
fault.
If you hear any abnormal noise when you run the
compressor, switch it off immediately and contact the ELGi
service engineer.
Follow all above points when you reinstall the compressor
at a different location.
If the compressor had been in storage for an extended
period before commissioning, contact the ELGi service
engineer.
