TURN ALL POWER OFF BEFORE STARTING INSTALLATION.
SUGGESTION: Before starting, use hacksaw to cut off top
flange of SoftStartRV unit so that it will fit in space provided. Install
SoftStart unit on right side wall toward front of electrical box, but below the
wiring access hole. Cut Black, Yellow and Blue SoftStart wires to 12-14 inches
in length and strip ends of wire. Attach Connectors as shown above.
Route full-length Brown and Red SoftStart wires to the top
of the Compressor. Then attach Connectors as indicated in drawing above.
Step 1. Follow White Compressor Wire from Compressor to Run
Capacitor. Disconnect from terminal and connect it to Blue SoftStart wire. Tape
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 onto the terminal that
the Black Compressor Wire was on. Route Brown wire over to and 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 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.
