NOTE: Route All Softstart wires into the electrical box, then crimp disconnects as shown in softstart box at top
Step 1) Follow the White Compressor wire to Run Capacitor “C” Terminal. Disconnect and connect it to the Blue SoftstartRV wire.
Step 2) Connect the Black SoftstartRV wire to the terminal the White wire was on.
Step 3) Follow the Red compressor wire from the compressor to the “HERM” terminal. At that point you will notice that the Red Compressor is on a Double Connector with a second Red wire. DO NOT DISCONNECT Either of the RED WIRES. Connect the Yellow SoftstartRV wire on the Terminal next to the Red compressor wire if it is available (see next step).
Step 4) IF you see a 2nd Red wire next to the Connector with the double Red wires, DISCONNECT it, tape the end and drop it. Then connect the Yellow SoftstartRV wire on the Terminal where you pulled off the second Red wire.
NOTE: IF you see a PTCR (see picture above), Pull it off the Terminal and remove the connector with the double red wires. Then put the connector with the double Red wires back on the Terminal where the PTCR was. If you then see another Red wire next to it, DISCONNECT it, tape the end and drop it. Then Connect the Yellow SoftstartRV wire on the Terminal where you just pulled off the Red wire.
Step 5) Follow the Black Compressor wire to the “PUR” Terminal (Purple wire will be directly across from it), Disconnect the Black wire and connect it to the Brown SoftstartRV wire.
Step 6) Connect the Red SoftstartRV wire on the Terminal that the Black compressor wire was on.
Before turning the power back on, secure wires to prevent the fan from pulling them in. Turn the Power and A/C breaker on, Turn the Fan on High until you hear it running, then Turn the A/C to Auto Cool and set the Thermostat to 55 degrees.
Look at the SoftstartRV for a Green light (There may be a full 3 min delay before the Green light comes on).
After you see the Green Light, Turn the power off, tidy up your wires and replace all covers. Then turn the A/C back on and allow it to run for 30 min at about 2 degrees below the outside temperature which should allow it to cycle a few times.
IF after 3 min you don’t have a green light, shut the A/C OFF and contact Tech Support, www.softstartrv.com/support and fill out a ticket.
