Route ALL SoftStart wires into the electrical box. Then crimp Connectors onto all SoftStart wires as indicated in drawing.
Step 1. Follow White Compressor wire to Terminal Board. Disconnect from Terminal Board and connect to Blue SoftStart wire.
Step 2. Connect Black SoftStart wire to the terminal on the Terminal Board that the White Compressor Wire was on.
Step 3. Disconnect the PTCR and remove the double Red wires. Connect double Red wires to terminal that the PTCR was on. Connect Yellow SoftStart wire on terminal that the Red wire was on.
Step 4. Disconnect the single Red wire that was next to PTCR. Connect Yellow SoftStart wire where the single Red wire was.
Step 5. Disconnect Black Compressor Wire from Terminal Board. Connect Black Compressor Wire to Brown SoftStart wire and tape connection with electrical tape.
Step 6. Connect Red SoftStart wire to the Freeze terminal that the Black Compressor Wire was on.
Secure wires to prevent Fan from pulling wires in. Tape connections with electrical tape.
Turn Power and A/C Breaker on. Turn A/C to Auto Cool setting and set 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.
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.
