Note: When viewed from the front of the indoor unit.
A: Route the indoor tubing and the drain hose to the
required piping hole position in the direction of left.
Tubing retainer
B: Insert the connecting cable into the indoor unit from
the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy
connection later.
C: Tape the 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.
G: Connecting the piping to the indoor unit and the drain
hose to drain pipe.
• Align the centre of the piping and sufficiently tighten the
flare nut by hand.
• Tighten the flare nut with a wrench, in accordance with
the following table.

• When extending the drain hose of the indoor unit,
install the drain pipe extension as shown in
diagram below.
H: Wrap in the insulation material around the
connecting 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.
• Wrap the area which accommodates the rear piping
housing section with vinyl tape.
• Bundle the piping and drain hose together by wrapping
them vinyl tape over the range within they fit into the rear
piping housing section.
C: 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 insulation material so that dripping from “sweating”
(condensation) will not damage furniture or floors.

F: Locating the indoor unit
• Hook the indoor unit onto the upper portion of
the installation plate (Engage the two hooks of the
installation plate into the openings at the rear top of
the indoor unit). Ensure that the hooks are properly
seated on the installation plate by moving the indoor
unit left and right.
• Press the lower left and right sides of the unit against the
installation plate unit until the hooks engage into their
slot (clicking sound).
Connection of pipes - Indoor
• Prepare the indoor unit’s piping and drain hose for
installation through the wall.
• Remove the tubing retainer (see illustration below)
and pull the tubing and drain hose away from chassis
(if required). For some models this is not needed.
• Replace the tubing retainer in its original position.

caution
When installing the indoor unit, be sure to remove the
relavant sections where required (see adjacent diagram
for example). This will allow piping and cable routing to
be completed without damaging the unit.
For rear right piping
Note: When viewed from the front of the indoor unit.
A: Route in indoor tubing and the drain hose in the
direction of rear right.
B: Insert the connecting cable into the indoor unit from
the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy
connection later.
