Installation
2. Art Cool Type Indoor Unit
• Preparing the indoor unit's piping and drain hose for
installation through the wall.
1) Route the indoor tubing and the drain hose in the
direction of rear left or right.
2) Tape the tubing, drain hose, and the connecting
cable. Be sure that the drain hose is located at the
lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the
unit.

insulate the hose with an insulation material* so that
dripping from "sweating"(condensation) will not damage
furniture or floors.
