Look at SoftStart LED lights. Green light should be “on”. Green light means the Compressor is running (there may be a full 3-minute delay before Green light comes on). IF there is no Green light after 4 minutes, call SoftStart Tech Support for assistance.
Re-install all A/C covers.
Turn A/C on, set near to outdoor temperature and run for 30 minutes.
After 30 minutes, operate A/C normally.
