•
The maximum height of the drain riser is 675 mm. Since
the drain pump mounted on this indoor unit is a high
head type, from the characteristic point of view, the
higher the drain riser the lower the draining noise.
Therefore, the drain riser of 300 mm or higher is recom-
mended.
•
For upward drain piping, keep the horizontal piping dis-
tance of 300 mm or less between the drain socket root
to the drain riser.

Keep the drain hose level or make a slight up-grade so
that air may not stagnate in the drain hose.
If air stagnates, the drain ma y flo w oppositely when
the drain pump stops and generate abnormal sound.

CAUTION
If drain stagnates in the drain piping, the piping may be

• If downward inclination cannot be ensured,
carry out upward drain piping.
• Install supports at a distance of 1 to 1.5 m so that the pip-

Make sure to use the attached drain hose (2) and the
metal clamp (1).
Insert the drain hose (2) into the drain socket up to the
point where the socket diameter becomes larger.
Put the metal clamp (1) to the taped hose end and
tighten the metal clamp (1) with torque 1.2~1.5 N·m
(120~150
N·cm).

CAUTION
• Do not tighten the metal clamp (1) with the torque more
than the
value.
The drain hose (2), the socket or the metal clamp (1) may
be damaged.
• Wrap the vinyl tape around the end of the metal clamp
(1) so that the sealing material (Large) (6) to be used at
the next process may not be damaged with the clamp
end or bend the tip of the metal clamp (1) inward as
shown.
