● Check that there are no gaps between the unit and the
ceiling panel, or between the ceiling panel and the ceiling
surface.
Gaps may cause water leakage and condensation.
● Check that the wiring is securely connected.
If it is not securely connected, the auto flap will not operate.
("P09" is displayed on the remote controller.) In addition,
water leakage and condensation may occur.

adjusted as follows.
● Adjust the louver to the desired angle using the remote controller.
The louver also has an automatic air-sweeping mechanism.

the layout of the room and furniture, etc. If cooling or heating
seems inadequate, try changing the direction of the airflow.
■ 4-Way Air Discharge Semi-Concealed Type (XM Type)
Checking the unit position
(1) Check that the ceiling hole is within this range:
600 × 600 mm
(2) Confirm that the positions of the indoor unit and the ceiling
are as shown in the diagram. If the positions of the ceiling
surface and unit do not match, air leakage, water leakage,
flap operation failure, or other problems may occur.
(Fig. 9-16)
A must be within the range of 13 – 18 mm.
If not within this range, malfunction or other trouble may
occur.

CAUTION
● Never place the panel face-down. Either hang it vertically
or place it on top of a projecting object. Placing it face-
