The power must be turned ON in order to change the flap

angle. (Do not attempt to move the flap by hand. Doing so

Temporary latches

	may damage the flap.)

attach the ceiling panel in place. (Fig. 3-44)

● The ceiling panel must be installed in the correct direction

relative to the unit. Align the REF. PIPE and DRAIN marks

on the ceiling panel corner with the correct positions on the

unit.

(2) Align the panel installation holes and the unit screw

holes. (Fig. 3-45)

(3) Tighten the supplied washer head screws at the

4 panel installation locations so that the panel is

attached tightly to the unit.

(4) Check that the panel is attached tightly to the ceil-

ing. (Fig. 3-46)

● At this time, make sure that there are no gaps between the

unit and the ceiling panel, or between the ceiling panel and

the ceiling surface.

● If there is a gap between the panel and the ceiling, leave

the ceiling panel attached and make fine adjustments to

the installation height of the unit to eliminate the gap with

the ceiling.

(1)Open the cover of the electrical component box for control PCB.

(2)Connect the 7P wiring connector (red) from the ceil- ing panel to the connector on the control PCB in the

unit electrical component box. (Fig. 3-48)

●If the connectors are not connected, the Auto flap will not operate. Be sure to connect them securely.

●Check that the wiring connector is not caught between the electrical component box and the cover.

●Check that the wiring connector is not caught between the unit and the ceiling panel.

(Direction that the unit faces has been changed to facilitate explanation.)
