Piping and Drain Hose Installation
* Since dewing results in a machine trouble, make sure to insulate both
connecting pipes. (Use polyethylene foam as insulating material.)
Piping and drain hose forming
1. Die-cutting front panel slit
Cut out the slit on the leftward or right side of the front panel for the left
or right connection and the slit on the bottom left or right side of the front
panel for the bottom left or right connection with a pair of nippers.
2. Changing drain hose
For leftward connection, bottom-leftward connection and rearleftward
connection’s piping, it is necessary to change the drain hose and drain
cap.
How to remove the drain cap
Clip the drain cap by needle-nose
pliers and pull out.
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
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.
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 equivalent tool.
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.

How to install the air inlet grille on the indoor
unit
• When attaching the air inlet grille,
perform the same process as for
removal but in reverse order.

Remark
: 1. Recommend to use double insulation lead wire for connect
remote control and air conditioner.
2. For wire operation, 1 remote control can control only 1 indoor
unit.
3. In wire operation, remote controller will return to initial
condition (PRESET, TIMER and CLOCK will return to
initial condition) when user shutdown power supply of air
conditioner.

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.
