CAUTION----------­
If drain stagnates in the drain piping, the piping may be
clogged.
• If sufficient downward inclination cannot be ensured,
carry out upward drain piping.
• Install supports at a distance of 1 to 1.5 m so that the
piping may not
deflect(Refer Fig. 10)
• 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 .Be sure to
fasten the screw of the metal clamp(1 )until the margin
of the screw thread decreases to 4 mm or less.

CAUTION-----------
• Tighten the metal clamp (1) on specified above otherwise.
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) (5) 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.

• The maximum height of the drain riser is 467 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
recommended.
• For upward drain piping, keep the horizontal piping
distance of 300 mm or less between the drain socket
root to the drain riser.
