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
mechanism.
