1.
Unlock the tubing clamp, and route the indoor unit refrigerant piping and drain hose to the required
chassis access hole on the right side (A).
2.
Pull the field drain and refrigerant piping, and the connecting cable from the access hole in the wall.
3. Guide the connection cable into the indoor unit, but don’t attach to the terminals. (Make a small loop
in the cable for easy connection later.)
4.
Connect the indoor unit drain hose and piping to the field drain piping and refrigerant piping (B). (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 (B). (See the
“Piping Bundling” and “Insulating the Piping” sections for instructions.)
6.
Optional: Secure a clamp to the strap boss with a screw (C).
7. Reroute the field drain and refrigerant piping back into the wall, and, after connecting the power wiring
and communication cables to the terminals on the indoor unit, hang the indoor unit.
