Drain hose installation

1

If necessary, connect the 2-meter extension drain hose to the drain hose. 

2

If you use the extension drain hose, insulate the inside of the extension drain hose 

with a shield.

3

Fit the drain hose into 1 of 2 drain hose holes, then fix the end of the drain hose 

tightly with a clamp. 

  If you don’t use the other drain hose hole, block it with a rubber stopper. 

4

Pass the drain hose under the refrigerant pipe, keeping the drain hose tight.

5

Pass the drain hose through the hole in the wall. Check if it slants downwards as 

seen in the picture. 

   

The hose will be fixed permanently into position after finishing  
the installation and the gas leak test; refer to page 11 for further details.

When installing the drain hose for the indoor unit, check if condensation draining is adequate.   
When passing the drain hose through the 65-mm hole drilled in the wall, check the following:

The hose must  

 NOT slant upwards. 

The end of the drain 

hose must NOT be 

placed under water. 

Do NOT bend the hose 

in different directions.

 

Keep a clearance of at 

least 5cm between the 

end of the hose and 

the ground.

 

Do NOT place the end 

of the drain hose in a 

hollow.
