Step 1. Follow White Compressor wire to “C” terminal on Run Capacitor. Disconnect from terminal and connect it to Blue SoftStart wire. Seal connection with electrical tape.
Step 2. Connect Black SoftStart wire to the terminal that the White Compressor wire was on.
Step 3. Connect Yellow SoftStart wire on terminal next to Red Compressor wire on HERM side of Run Capacitor.
Step 4. IF there is a second Red wire next to Red Compressor wire on HERM side of Run Capacitor, disconnect it, seal end with tape and drop it.
Step 5. Follow Black Compressor wire to the COMP Relay. Disconnect Black wire from Relay and connect to Brown SoftStart wire.

Secure all wires. Tape connections with electrical tape.
Turn Power and A/C Breaker on. Turn A/C to Auto Cool setting and the thermostat to 55ºF.
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.
