a patient or cause disturbances or interference in video broadcasting equipment.
Never operate the air conditioner with the air filter removed.

Turning off the power supply before that time could result in water
leakage or damage.
Never install the unit where run-off could result in damage.
If the humidity in the room exceeds 80% or if the drain becomes
clogged, water may drain off of the indoor unit. When the unit is
used for heating, there may be drainage from the outdoor unit. If
