TURN OFF ALL POWER AND BREAKERS BEFORE STARTING INSTALLATION.

Route all SoftStart wires into the electrical box, then crimp Connectors onto all SoftStart Home wires as indicated in drawing.

Step 1. Follow Red Compressor wire FROM Compressor TO Run Capacitor. Disconnect Red wire from Run Capacitor and connect it to Blue SoftStart wire. Tape connection.

Step 2. Connect Black SoftStart wire onto the terminal that the Red Compressor wire was on.

Step 3. Connect Yellow SoftStart wire onto an empty HERM terminal next to the Yellow Compressor wire.

Step 4. Since there is no Start Capacitor, this step is skipped.

Step 5. Follow Black Compressor wire FROM Compressor TO the Compressor Contact Relay. Cut Eye Ring from Black Compressor wire. Crimp Female connector onto Black Compressor wire and connect it to Brown SoftStart wire. Tape connection.

Step 6. Connect Red SoftStart wire onto the terminal that the Black Compressor wire was on.

Secure all wires. 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. Run LED 1 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.
