Turn Power and A/C Breaker on. Turn A/C to Auto Cool setting and set the thermostat to 55ºF (or as low as possible).

Look at SoftStart Marine RUN LED light (on left side). Green light should be “on”. Green light means the Compressor is running (there may be a full 3-minute “Test Mode” delay before Green light comes on). IF there is no Green light after 4 minutes, call SoftStart Tech Support for assistance.

After establishing Green light operation, 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.
