TURN ALL POWER OFF BEFORE STARTING
INSTALLATION.
NOTE: The instructions for diagrams A and B are the same. The difference is the type of Start Relay used in the A/C system.
Route all SoftStart wires into the electrical box. Crimp connectors onto ends of SoftStart wires as indicated in drawing.
Step 1. Follow White Compressor wire from Compressor to 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 Start Relay and disconnect it. Connect Black wire to the Brown SoftStart wire. Tape connection.
Step 6. Connect the Red SoftStart wire onto the terminal that the Black Compressor wire was on.
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.
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.
