3-6-5. Checking After Installation
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 fl ap will not operate. (“P09” is displayed on the remote controller.) In addition,
water leakage and condensation may occur.
3-6-6. When Removing the Ceiling Panel for Servicing
When removing the ceiling panel for servicing, remove the air-intake grille and air fi lter, disconnect the wiring connector
inside the electrical component box, and then remove the 4 mounting screws.
3-6-7. Adjusting the Auto Flap
The air-direction louver on the ceiling panel outlet can be adjusted as follows.
Adjust the louver to the desired angle using the remote controller. The louver also has an automatic air-sweeping
