suppled harness. Route wires from heater assembly to
indoor options module in main control box. Refer to
Figure 19 for indoor option module location. Stage 1 to J6
and stage 2 (if installed) to J7. Refer to included schematic

12. After heater is installed and before applying power, verify
the following:
a. Heating elements are not damaged or pinched.
b. Heating elements are not short circuited to each other
or to the heater frame or equipment cabinet.
