1. With power door removed, remove junction box cover
adjacent to female plug on casing upper channel. (See Fig.
10.)

upper hole on the side channel adjacent to the furnace. Be
sure bushing projects into furnace opening protecting wires
from sharp edges on cabinet opening.

10.
4. Plug unused hole on top of unit with plug provided in parts
bag.
5. Route power wires through bushing channel at top of
