- Blower device such as ceiling fan or ventilating fan
a󰀨ects the airow from the indoor unit.
- Ambient temperature changes drastically.
- Excessive force or vibration is applied to the motion
sensor kit.
- Fluid or corrosive gas exists on the installing site.
- Continuous use of the indoor unit in a high humidity
environment.
- Weather a󰀨ects directly to the surface of the motion
sensor.
- Static electricity or electromagnetic wave is generated on

Pay attention that the detecting function is decreased if the lens
for sensor smudges.
In this case, wipe o󰀨 smudges by a cotton swab soaked alcohol
(Isopropyl alcohol is recommended.) or a soft cloth.
(When wiping o󰀨 smudges on the lens for sensor, do not apply
