The angle change of the flap is possible while the power supply is turned
on. (Do not move forcibly the flap with hands. It may break the flap.)
1. For tentative hanging, insert the tentative hanging metal (stainless) inside of
the ceiling panel into the square hole of the indoor unit. (Fig. 2)
• The ceiling panel has directional ability against the indoor unit. Direct the
mark of refrigerant pipe at the ceiling panel corner toward the pipe side.
• Holding the ceiling panel, remove it while pushing the tentative hanging
metal toward the outside. Corner of drain pipe

corners of the suction port until the panel is fitted closely to the
main unit. (Fig. 3)

(4) Cabling of ceiling panel
1. Open cover of the electric parts box.
2. Connect the flap motor wiring connector out
of the ceiling panel to the connector 5P
(CN33: white) on P.C. board of the indoor unit.
• Connect the connector surely because
the flap does not work if the connector
is not connected.
3. Mount cover of the electric parts box in the
reverse procedure of opening of the cover.
• Check whether the wiring connector is
pinched between the electric parts box
and the cover or not.
• Check whether the wiring connector is
pinched between the indoor unit and the
ceiling panel or not.
As shown in the figure, pass the clamping material through inside of the slit.
After connection, store the connector section in the electric parts box.

ceiling panel.
2. Install the adjust corner cap to the ceiling panel, and fix it with
the mounting screws. (accessory part)
B. Installation of suction grille
• To install the suction grille, follow to the reverse procedure of the
removal. This ceiling panel can be installed from anyone of 4
directions by turning the suction grille. Change the direction on
the customer’s demand or according to the direction matching of
the suction grille when multiple units are installed.
• When installing the suction grille, be sure not to pinch the
flap motor wiring connector.
• Be sure to attach a strap to prevent falling of the suction grille to

3. Others
After confirmation of the above items, hand a set of this manual, manuals for the indoor unit,
manual for products sold separately, etc. to the customer. For cleaning of the filter, be sure to
ask the maintenance professional.
Pin
Install the adjust corner cap horizontally
to the ceiling surface so that 3 hooks of
the adjust corner cap are set in holes of
the ceiling panel. And then fix it with the
mounting screws (accessory part).
A. Check after installation
• Check again there is no clearance between the
indoor unit and the ceiling panel, and between
the ceiling panel and the ceiling surface.
* A clearance causes water leak or dewing.
• Check the cables are connected surely.
* Incomplete connection causes a trouble such as the flap does not work.
B. For wireless remote controller
• For details of installation, refer to the Installation Manual attached to the
wireless remote controller kit (sold separately).
Positions of suction grille hooks at shipment from the factory
* Although the suction grille can be installed from any
