28 P5417054Use Conditions and Precaution Statements1. The motion sensor operates by detecting minute changes in temperature in the infrared spectrum.Moving objects or human activity with temperature differences can be distinguished from thetemperature of the surrounding body.DO NOT install the decorative panel equipped with motion sensor (P-AP160NAE1) in the followingplaces: It can result in poorly identified or defined motion, or degraded performance of the motionsensor.2. Human activity or moving objects can set off the motion detector. The sensor inside a suspendedunit has a range of 13 ft (4m). Assuming there is human activity in the area, a signal is sent toactivate the unit, and the temperature of the area is cooled to the set temperature. When activityceases, the unit is signaled to relax, and the ambient air temperature rises. Thus, energy efficiencyis achieved.8.4.3 Caution for Electrical WiringDo not connect the power supply wiring and the communication cable into one terminal.The manual switchbox is required when a communication cable is required.Indoor UnitSwitchboxSIndoor Unit Indoor Unit Indoor UnitIndoor UnitIndoor UnitSGFCIGFCIR L1 SL2 MpNR L1 SL2 MpN R L1 SL2 MpN R L1 SL2 MpNR L1 SL2 MpN R L1 SL2 MpN▫ Where ambient temperature changes drastically.▫ Where excessive force or vibration is applied to the sensor.▫ Where static electricity or electromagnetic waves may generate.▫ Where interference of infrared light such as glass or mist is in the detecting area.▫ Where the lens for sensor is exposed in high temperature and humidity for a long time.▫ Where fluid and corrosive gas exist.▫ Where direct light such as sunlight or headlights affect the sensor.▫ Where hot air from a heater, etc. directly affects the sensor.▫ Where the air flow returns to the sensor indirectly by hitting obstacles such as shelf, locker, etc.▫ Where the blower devices such as ceiling fan, ventilating fan, etc. affect the air flow from theindoor unit.▫ Where weather directly affects the surface of the sensor.▫ Where the lens surface may be smudged or damaged, such as from a dusty environment.Detecting function will decrease if the lens for sensor smudges.In this case, wipe off smudges using a cotton swab soaked with alcohol (Isopropyl alcohol isrecommended) or a soft cloth. (When wiping off smudges on the lens of the sensor, do not applyexcessive force. If excessive force is applied, the resin lens may be damaged and this may causemalfunctions such as misdetection or undetectable motion.)
