Piping and Drain Hose Installation
* Since dewing results in a machine trouble, make sure to insulate both con-
necting 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.

Drain hose
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 the 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.
Do not apply lubricating oil
(refrigerant machine oil) when
inserting the drain cap. Application
causes deterioration and drain
leakage of the plug.
Insert a hexagon
wrench (4 mm).
No gap
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,
the contrary of the removed
operation is performed.
Wiring Connection
Wiring of the connecting cable can be carried out without removing the
front panel.
1. Remove the air inlet grille.
Open the air inlet grille upward and pull it toward you.
2. Remove the terminal cover and cord clamp.
3. Insert the connecting cable (according to the local cords) into the pipe hole
on the wall.
4. Take out the connecting cable through the cable slot on the rear panel so
that it protrudes about 15 cm from the front.
5. Insert the connecting cable fully into the terminal block and secure it tightly
with screws.
6. Tightening torque : 1.2 N·m (0.12 kgf·m)
7. Secure the connecting cable with the cord clamp.
8. Fix the terminal cover, rear plate bushing and air inlet grille on the indoor
unit.
How to connect the connecting cable
• Be sure to refer to the wiring system diagram labeled inside the front
panel.
• Check local electrical cords and also any speci
fi
c wiring instructions or
limitations.
NOTE
• Use stranded wire only.
• Wire type : More than H07RN-F or 245 IEC66 (1.0 mm
2
or more).
