Route Black, Yellow and Blue SoftStart wires into the
electrical box. Then crimp Connectors onto SoftStart wires as indicated in drawing.

Route Brown and Red SoftStart wires to the top of the
Compressor. Then attach Connectors as indicated in drawing.

IF there are 3 Capacitors, perform Step 4. If there are NOT
3 Capacitors, skip Step 4.

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. Remove the Compressor Cap. Disconnect Black wire
and connect to Red SoftStart wire. Tape connection.

Step 6. Connect Brown SoftStart wire (with Female Flag
connector) onto the terminal that the Black Compressor Wire was on. Route Brown
wire out with Red and White Compressor wires. Replace cap.

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.

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.
