2.
Pull the field drain piping and refrigerant piping, and the connecting cable from the access hole in the

Connect the indoor unit drain hose and piping to the field drain piping and refrigerant piping (C). (See
the “Connecting the Indoor Unit Piping to Field Piping” section for instructions.)
5. Tape the drain hose, piping, and the connecting cable together, and install insulation (C). (See the
“Piping Bundling” and “Insulating the Piping” sections for instructions.)
6.
Reroute the indoor unit drain hose and refrigerant piping across the back of the indoor unit, and lock
