The timer can be set from 1 to 7 hours. ● In the Cool, Energy Saver, Dry Mode, the setting temperature increases by 1 °C after 30 minutes and additional 1 °C after another 30 minutes for a more comfortable sleep. ● The setting temperature increases up to 2 °C from the preset temperature. 3 Delay ON/OFF Timer Delay ON - When the air conditioner is off, set it to automatically turn on from 1 to 24 hours later, at its previous mode and fan settings. Delay OFF - When the air conditioner is on, set it to automatically turn off from 1 to 24 hours later. NOTE ● Each press of the Timer button advances the timer by 1 hour. After the last press the display returns to the temperature setting. 4 Operation Mode Press the Mode button to cycle between 4 types of air conditioner operation: Cool / Energy Saver / Fan / Dry. Cool - This mode is ideal on hot days to cool and dehumidify the room quickly. Use the Temp buttons to set the desired room temperature and use the Fan Speed button to set the desired fan circulation speed. Energy Saver - In this mode the compressor and fan turn off when the set temperature is achieved. Approximately every 3 minutes the fan turns on to allow the unit sensor to accurately determine if more cooling is needed. Fan - In this mode the fan circulates air but the compressor does not run. Use the Fan Speed button to set fan speed to High, Medium or Low. In this mode, you cannot adjust the set temperature. Dry - This mode is ideal for rainy and damp days to dehumidify the room rather removed from the room by the combination of compressor operation and the fan speed off once the set temperature is reached. Fan speed cannot be adjusted in Dry mode. 5 Wi-Fi Enables connection of the air conditioner to the home Wi-Fi. ● Wi-Fi Pairing : Mode + Fan Speed ● Wi-Fi Off : Power + Fan Speed OPERATION 13 6 Clean Filter The Clean Filter LED lights up to notify you and Temp together on the control panel to turn off the Clean Filter light.

Insert AAA (1.5 V) batteries before using the remote control. 1 Ventilation Push the ventilation lever in to the closed position to maintain the best cooling performance. Pull the ventilation lever out to open the vent and draw fresh air into the room. Remove the cover on the back of the remote control. Close Open 2 Insert the new batteries and make sure that the + and - terminals of the batteries are installed correctly. NOTE ● New batteries are supplied with the air conditioner for use in the remote control. ● Do not use a rechargeable battery. Make sure that the battery is new. ● In order to prevent discharge, remove the battery from the remote control if the air conditioner is not going to be used for an extended period of time. ● Keep the remote control away from extremely hot or humid places. ● To maintain optimal operation of the remote control, the remote sensor should not be exposed to direct sunlight. OPERATION 15 Air Direction of the air conditioner’s louvers. Direction Slinger Fan This air conditioner is equipped with a slinger fan. (See drawing.) The fan’s outer ring picks up the condensed water from the base pan if the water level gets high enough. The water is then picked up by the fan and expelled through the condenser, making levers of the vertical louvers to the left or right. Ring Direction up or down. NOTE ● When the weather is extremely hot, the unit may turn off automatically to protect the compressor. 16 SMART FUNCTIONS SMART FUNCTIONS Using LG SmartThinQ Application Things to check before using LG SmartThinQ • For appliances with the logo 1 Check the distance between the appliance and the wireless router (Wi-Fi network). • If the distance between the appliance and the wireless router is too far, the signal strength becomes weak.
