• Bundle the piping and drain hose together by wrapping

them with vinyl tape for enough to cover where they fit into
the rear piping housing section.

Connecting the pipings to the indoor unit and
the 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.

Wrap the insulation material around the con-
necting portion.

• Overlap the connection pipe heat insulation and the indoor

unit pipe heat insulation material. Bind them together with
vinyl tape so that there is no gap.

Route the indoor tubing and the drain hose to
the required piping hole position.

Insert the piping, drain hose, and the connect-
ing cable into the piping hole.

Insert the connecting cable into the indoor unit.

• Don't connect the cable to the indoor unit.

• Make a small loop with the cable for easy connection later.

Indoor unit installation

• Hang the indoor unit from the hooks at the top of the instal-

lation plate.

• Insert the spacer etc. between the indoor unit and the

installation plate and separate the bottom of the indoor unit
from the wall.

Tape the drain hose and the connecting cable.
