This document is an owner's manual for an LG wall-mounted air conditioner, providing comprehensive information on its operation, smart functions, and maintenance.
Function Description
The LG air conditioner is designed to provide cooling, heating (for cooling & heating models), and dehumidification, ensuring a comfortable indoor environment. It features various modes of operation including Cooling, Heating, Dehumidification, Fan, and Auto Changeover/Auto Operation. The unit can be controlled via a wireless remote control or an on/off button on the indoor unit itself for emergency use.
Key functions include:
- Cooling Mode: Reduces indoor temperature.
- Heating Mode: Increases indoor temperature (available on cooling & heating models).
- Dehumidification Mode: Removes excess moisture from the air, preventing mold and maintaining optimal humidity.
- Fan Mode: Circulates indoor air without cooling or heating.
- Auto Changeover/Auto Operation Mode: Automatically selects the appropriate mode (cooling or heating) to maintain a set temperature.
- Jet Mode: Quickly changes room temperature (cooling or heating).
- Air Flow Direction Function: Adjusts the vertical and horizontal air flow direction using deflectors (horizontal adjustment may be model-dependent).
- On/Off Timer: Sets the air conditioner to turn on or off automatically at a desired time.
- Sleep Function (Optional): Automatically turns off the air conditioner when you go to sleep, adjusting temperature for comfortable sleep. In Cooling and Dehumidification Modes, the temperature increases by 1 °C after 30 minutes and another 1 °C after another 30 minutes (up to 2 °C from preset temperature).
- Simple Timer Function (Optional): Automatically turns off the air conditioner after a set number of hours (up to 7 hours).
- Energy Display Function (Optional): Displays instantaneous (kW) and cumulative (kWh) power consumption on the indoor unit.
- Light Off Function (Optional): Adjusts the brightness of the indoor unit's display screen.
- Comfort Air Function (Optional): Sets the vane to a preset position to deflect air away from occupants.
- Energy Saving Function (Optional): Minimizes power consumption during Cooling by increasing the set temperature to an optimal level (automatically settles at 22 °C if ambient temperature is below 22 °C).
- Energy Control Function (Optional): Decreases power input by 20%, 40%, or 60% compared to rated power input, available in Cooling Mode.
- Special Functions (Optional):
- Air Purification Function: Purifies air using ion particles (Ionizer) and filters (Plasma), removing bacteria, harmful substances, and microscopic contaminants. Can be used without turning on the air conditioner.
- Silent Function: Reduces noise from outdoor units, preventing potential claims by neighbors. Available in Cooling, Heating, Auto Changeover, and Auto Operation Modes.
- Ion Care Function: Keeps skin moisturized by generating ion clusters. Available in Cooling, Fan Mode, and Air Purification functions.
- Jet Dry Function: Maximizes dehumidification performance. Available in Cooling, Dehumidification, Auto Operation, and Fan Mode.
- Low Heating Function: Maintains a minimum room temperature to prevent objects from freezing, useful in unoccupied spaces.
- Auto Clean Function: Removes remaining moisture inside the indoor unit to prevent mold and odors.
- Mosquito Away Function: Generates a high-frequency wave to scare away mosquitoes. Can be used without turning on the air conditioner.
Important Technical Specifications

Usage Features
- Remote Control: The primary interface for operating the air conditioner, offering control over modes, temperature, fan speed, air flow direction, and various special functions.
- Emergency On/Off Button: Allows basic operation (on/off) of the indoor unit if the remote control is unavailable. The fan speed is set to high, and temperature cannot be altered (fixed at 22 °C for cooling-only, 22 °C to 24 °C for cooling & heating models).
- Auto Restart: After a power failure, the unit resumes its last operation several minutes after power is restored, if the function is enabled.
- Smart ThinQ Application: Enables smart control of the air conditioner via a smartphone. Users can register the appliance, connect to Wi-Fi, and access various settings and features.
- Smart Diagnosis™: A function accessible via the Smart ThinQ app that provides useful information for troubleshooting malfunctions. It requires the appliance to be connected to power and the phone to correctly receive buzzer beeps from the indoor unit.
- °C/°F Conversion Function (Optional): Allows switching the temperature unit between Celsius and Fahrenheit by pressing and holding the SWING button for 5 seconds.
Maintenance Features
Regular maintenance is crucial for optimal performance and longevity of the air conditioner.
- Air Filter: Clean every 2 weeks by vacuuming or hand washing.
- Triple Filter (Optional): Clean every 3 months by vacuuming or brushing. Do not wash with water.
- 3M Filter (Optional): Clean every 6 months by vacuuming or brushing. Do not wash with water.
