screw securing the drain hose and then pulling out 
the drain hose.

•  When removing the drain hose, be careful of any 

sharp edges of steel plate. The edges can injuries.

•  To install the drain hose, insert the drain hose 

fi

 rmly until the connection part contacts with heat 

insulator, and then secure it with original screw.

How to 

fi

 x the drain cap

1)  Insert hexagon wrench (4 mm) 
  in a center head.

2)  Firmly insert the drain cap.

Firmly insert the drain hose and drain cap; otherwise, water may leak.

CAUTION

Left-hand connection with piping

•  Bend the connecting pipe so that it is laid within 43 mm above the wall 

surface. If the connecting pipe is laid exceeding 43 mm above the wall 
surface, the indoor unit may unstably be set on the wall.

  When bending the connecting pipe, make sure to use a spring bender so 

as not to crush the pipe.

Bend the connecting pipe within a radius of 30 mm.

NOTE

If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the 
connecting pipes to the auxiliary pipes and wrap the facing tape around 
them.

In case of right or left piping

•  After scribing slits of the front panel 

with a knife or a making-off pin, cut 
them with a pair of nippers or an 
equivalent tool. 

In case of bottom right or bottom left piping

•  After scribing slits of the front panel 

with a knife or a making-off pin, cut 
them with a pair of nippers or an

•  Carefully arrange pipes so that any pipe does not stick out of the rear 

plate of the indoor unit.

•  Carefully connect the auxiliary pipes and connecting pipes to one 

another and cut off the insulating tape wound on the connecting pipe 
to avoid double-taping at the joint; moreover, seal the joint with the 
vinyl tape, etc.

•  Since dewing results in a machine trouble, make sure to insulate both 

connecting pipes. (Use polyethylene foam as insulating material.)

•  When bending a pipe, carefully do it, not to crush it.

1.  Pass the pipe through the hole in the wall and hook the indoor unit on the 

installation plate at the upper hook.

2.  Swing the indoor unit to right and left to con
