However, do not set to the FACE mode with the vents closed.

NOTICE
If operations are continued for a long time with the air conditioner set to the lowest temperature and minimum air flow, there is
danger that the receiver drier may freeze.
If it freezes and no cold air comes out, stop using the cooling, and set to a higher temperature and the maximum air flow. Run for
a short time under these conditions, then return to the cooling operation.
