FULL COOL Mode
1. Unplug unit and turn off the CB located in the controller box.
2. Remove the Condenser Motor wires CF1, CF2, and CF3 from the input side of the compressor
contactor, installed during the Rotation Check. Re-tighten input wires.
3. Remove the Low Speed Evaporator wires EF1, EF2, and EF3 from J10 on the PM.
4. Connect the CF and EF wires to the output side (right side) of the compressor contactor. Be sure to
maintain wiring 1-1 2-2 3-3. See Figure 28 on page 60.
5. Locate J1 connector top left side of PM. Disconnect J1 connector from the PM. Install 3 18 GA 3”
long jumper wires on the J1 connector. Leave J1 disconnected during cool mode. See Figure 28 on
page 60.
a. Pin 1 (wire 29VAC 0) to pin 6 (wire CC1).
b. Pin 2 (wire 29VAC 1) to pin 3 (wire HPCO-0).
c. Pin 4 (wire HPCO-1) to pin 5 (wire CC0).
6. Plug unit into, turn main CB ON and OFF to maintain box temperature. If compressor runs backward
but the fans run correct, swap the Red and White wires on the output side of the compressor contactor.
If unit is running in high ambient with high box temperature, monitor compressor amperage using a amp
probe. Maintain <12 amp by closing suction service to limit capacity.
