 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 pip-

ing may not deflect. 

(Refer to Fig. 14)

• 

Make sure to use the attached drain hose (1) and the 
metal clamp (2). 
Insert the drain hose (1) into the drain socket up to the 
point where the socket diameter becomes larger.  

  Put the metal clamp (2) to the taped hose end and 

tighten the metal clamp (2) with torque 1.35±0.15 N·m 

(135±15 N·cm).

 CAUTION

• 

Do not tighten the metal clamp (2) with the torque more 

than the specified value.

 

The drain hose (1), the socket or the metal clamp (2) may 
be damaged.

• 

Wrap the vinyl tape around the end of the metal clamp 
(2) so that the sealing material (Large) (10) to be used at 
the next process may not be damaged with the clamp 
end or bend the tip of the metal clamp (2) inward as 
shown.

• 

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.

Level or upward 

inclination

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 may flow oppositely when 

the drain pump stops and generate abnormal sound.
