Piping and drain hose installation
Piping and drain hose forming
* Apply heat-insulation for both refrigerant pipe and drain hose surely so that no dew generates inside of the
equipment. (use polyethylene foam for insulating material.)
1. Remove the front panel
2. 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.
3. 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.
Without changing the drain hose position, the indoor unit will not fit to the wall.
How to remove the drain hose
The front panel must be removed for piping
connections in the left, bottom left, and rear left
directions.
• Open the air intake grille upward.
• Remove the four screws securing the front panel.
• Slightly open the lower part of the front panel, and
then pull the upper part of the front panel toward you
to remove it from the rear plate.
• 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 firmly until the connection part
contacts with heat insulator, and the secure it with original screw.

In case of right or left piping
After scribing slits of the front panel with a knife or a
marking-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 connection pipe within a radius of 30 mm.
To connect the pipe after installation of the unit (figure)
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 pipe to the auxiliary pipes and
wrap the facing tape around them.
