● Hold the air filter and the air inlet grille securely by hand when attaching or removing it. If not, it may

cause the unit to fall, resulting in serious injury.

● Use light pressure with a clean soft cloth when cleaning the lens of the motion sensor. The surface

material of the lens is easily scratched, blemished, and can result in degraded performance of the sensor.

NOTICE

● Turn OFF the power source before maintenance work. If the power source is not turned off, a fire or an

electric shock may result.

● Perform the maintenance work with a stable foothold or foundation. This may prevent falling or injury.
