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.
NOTE: If the drain hose is routed inside the room,
insulate the hose with an insulation material* so that
dripping from "sweating"(condensation) will not damage
furniture or floors.
*Foamed polyethylene or equivalent is recommended.
3) Connecting the pipings to the indoor unit and drain
hose to drain pipe.
• Align the center of the pipes and sufficiently tighten
the flare nut by hand.
• Tighten the flare nut with a wrench.
• When extending the drain hose at the indoor unit,
install the drain pipe.
4) Wrap the insulation material around the connecting
portion.
• Overlap the connection pipe insulation material and
the indoor unit pipe insulation material. Bind them
together with vinyl tape so that there is no gap.
• Wrap the area which accommodates the rear piping
housing section with vinyl tape.
• Bundle the piping and drain hose together by wrap-
ping them with vinyl tape for enough to cover where
they fit into the rear piping housing section.
