The location of the electrical service entrance is
illustrated in Figure 58, p. 75. It’s important to complete
the unit power wiring connections onto either the main
terminal block or the factory mounted, non-fused
disconnect switch. The disconnect switch is inside the
unit control panel. Refer to the component location
diagrams that shipped with the unit for specific
termination points.
Provide proper grounding for the unit in accordance
with local and national codes.
