(3) Installation of ceiling panel
Be sure to change angle of the flap while the power supply is
turned on.
(Never move the flap forcibly with hands; otherwise the flap may
be broken.)
1. Hang tentatively the tentative metal (stainless) of the indoor unit to
hanging section of the ceiling panel. (Fig.2)
• The ceiling panel has the directive performances against the indoor
unit. Mount the ceiling panel with arranging the tentative hanging
position.
• When removing the ceiling panel, push the tentative hanging metal
toward outside while holding the ceiling panel.
2. Match the mounting hole of the panel with the screw hole of the indoor
unit.
3. Using the attached washer based screw, tighten 4 positions at 4 corners
of the suction port until the panel is fitted closely to the main unit. (Fig. 3)
4. Check the panel is fitted closely to the ceiling.
• In this time, check there is no clearance between the indoor unit and
the ceiling panel, and also between the ceiling panel and the ceiling
surface. (Fig.4)
(Fig. 3)
• As shown in the following figure, a trouble may be
caused if the screws are incompletely tightened.

(4) Cabling of ceiling panel
1. Open cover of the electric parts box.
2. Connect the flap motor wiring connector which
comes forth from the ceiling panel to the connector
5P (CN33: white) on the P.C. board of the indoor unit.
• Connect the connector surely because the
flap does not work if the connector is
incompletely connected.
3. Mount cover of the electric parts box in the
reverse procedure of opening of the cover.
• Check whether the wiring connector is not
pinched between the electric parts box and
the cover.
• Check whether the wiring connector is not
pinched between the indoor unit and the
ceiling panel.
