• For left drain pipe outlet, remove the rubber plug and the 

insulation on the drain pipe connecting opening on the 
left side of the unit and change the position to the right 
side.

• Insert the rubber stopper securely, all the way to the 

base, in order to prevent water leakage.

• The diameter of the drain pipe should be greater than or 

equal to the diameter of the connecting pipe. (Vinyl tube; 
pipe size: 20 mm; outer dimension: 26 mm)

• Keep the drain pipe short and sloping downwards at a 

gradient of at least 1/100 to prevent air pockets from 
forming. 

(Refer to Fig. 21)

• Use the drain hose (1) and the metal clamp (2). 

Insert the drain hose into the drain socket, up to the gray 
tape. 

(Refer to Fig. 22)

 

Tighten the metal clamp until the screw head is less than 
4 mm from the hose. 

(Refer to Fig. 23)

(Be careful of the installation direction. Install so that the 
metal clamp does not contact the intake grill.)

• Wrap the sealing pad (8) (accessory) over the clamp and 

drain hose to insulate. 

(Refer to Fig. 23)

• No folding of drain hose inside the indoor unit. 

(Refer to Fig. 24)

(If there is slack in the drain hose, it may cause damage 
to the intake grill.)

NOTE

NOTE

NOTE

NOTE

• To ensure no excessive pressure is applied to the included 

drain hose (1), do not bend or twist when installing. (This may 
cause leakage.)

• If converging multiple drain pipes, install according to the 

procedure shown below.

Select converging drain pipes whose gauge is suitable for the 
operating capacity of the unit.

(2) Confirm that smooth drainage is achieved after the pip-

ing work.

• Add 0.6 liter of water in the drain pan from the air outlet 

for confirming drainage. 

(Refer to Fig. 25)

CAUTION

• Drain piping connections

Do not connect the drain piping directly to sewage pipes that 
smell of ammonia. The ammonia in the sewage might enter 
the indoor unit through the drain pipes and corrode the heat 
exchanger.

• Keep in mind that it will become the cause of getting drain 

pipe blocked if water collects on drain pipe.
