Cut out the slit on the left or right side of the back body for the left or right
connection and the slit on the bottom left or right side of the back body
for the bottom left or right connection with a pair of nippers.
2. Changing drain hose
For leftward connection, bottom-leftward connection and rear leftward
connection's piping, it is necessary to change the drain hose and drain cap.
How to remove the drain hose
The drain hose can be removed by removing the
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 remove the drain cap
Clip the drain cap by needle-nose
pliers and pull out.
How to fi x the drain cap
1) Insert hexagon wrench (4 mm)
in a center head.
2) Firmly insert the drain cap.
Do not apply lubricating oil
(refrigerant machine oil)
when inserting the drain
cap. Application causes
deterioration and drain
leakage of the plug.
CAUTION
Firmly insert the drain hose and drain cap; otherwise, water may leak.

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.
CAUTION
Bind the auxiliary pipes (two) and connecting cable with facing tape
tightly. In case of leftward piping and rear-leftward piping, bind the
auxiliary pipes (two) only with facing tape.
Auxiliary pipes
Installation plate
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.
