„ Installation of ceiling panel
(Sold separately)
Install the ceiling panel according to Installation
Manual attached with it after piping / wiring work has
completed.
Check that installation of indoor unit and ceiling
opening part is correct, and then install it.
REQUIREMENT
y Joint the connecting sections of ceiling panel,
ceiling surface, ceiling panel and indoor unit
closely.
Any gap between them will cause air leakage
and the generate condensation or water leakage.
y Remove the adjust corner caps at the four
corners of the ceiling panel, and then install the
ceiling panel onto the indoor unit.
y Make sure that the claws of the four adjust
corner caps are securely fit.
* Improper fitting of the claws may cause water
leakage.
„ Installation of remote
controller (Sold separately)
For installation of the wired remote controller, follow
the Installation Manual attached with the remote

„ Wireless type
(Sold separately)
The sensor of indoor unit with wireless remote
controller can receive a signal by distance within
approx. 7 m. Based upon it, determine a place where
the remote controller is operated and the installation
place.
y Operate the remote controller, confirm that the indoor
unit receives a signal surely, and then install it.
y Keep 1 m or more from the devices such as
television, stereo, etc.
(Disturbance of image or noise may generate.)
y To prevent a malfunction, select a place where is not
influenced by a fluorescent light or direct sunlight.

Drain piping

CAUTION
Following the Installation Manual, perform the
drain piping work so that water is properly
drained, and apply a heat insulation so as not to
cause a dew dropping.
Inappropriate piping work may result in water
leakage in the room and wet of furniture.
„ Piping / Heat insulating
material
Require the following materials for piping and heat
insulating at site.
Hard vinyl chloride pipe VP25
Piping
(Outer dia. : Ø32 mm)
Foam polyethylene :
Heat insulator
Thickness 10 mm or more
„ Flexible hose
Use the attached flexible hose to adjust centre
discrepancy of the hard vinyl chloride pipe or to adjust
the angle.
y Do not use the flexible hose as stretched, or do not
deform it more extent than that in the following figure.
y Be sure to fix the soft end of the flexible hose with
the attached hose band.
y Use the flexible hose on a horizontal level.

REQUIREMENT
y Be sure to perform heat insulation of the drain
pipes of the indoor unit.
y Never forget to perform heat insulation of the
connecting part with the indoor unit.
An incomplete heat insulation causes dew
dropping.
y Set the drain pipe with downward slope (1/100 or
more), and do not make swelling or trap on the
piping.
It may cause an abnormal sound.

y For length of the traversing drain pipe, restrict to
20 m or less.
In case of a long pipe, provide support brackets
with interval of 1.5 to 2 m in order to prevent
waving.

y Be sure not to apply force to the connecting part of
the drain pipe.
y The hard vinyl-chloride pipe cannot be directly
connected to the drain pipe connecting port of the
indoor unit.
For connection with the drain pipe connecting port,
be sure to use / fix the attached flexible hose with
the hose band, otherwise a damage or water leak
is caused on the drain pipe connecting port.
