15. For models with the control box in the outdoor section, route the wires through the wire access
opening in the divider panel, then up to the unit control box entering through the bottom wire
access opening on the left side. See
Figure 8
. For models with the control box above the heat
exchanger section, route the wires through the hole in the panel separating the heater
compartment and the control box compartment. See
Figure 9
. Secure wires to the existing
harness.
16. In the unit control box, route the wires along the existing harness to contactor CC1. Secure wires
to existing harness.
