This document is an owner's manual for an LG Wall Mounted Air Conditioner. It provides detailed information on safety precautions, product introduction, operating instructions, and maintenance.
Function Description:
The LG Wall Mounted Air Conditioner is designed to provide cooling, heating (for heat pump models), dehumidification, and air circulation for indoor spaces. It incorporates various features to enhance comfort and air quality, such as a Plasma Purification function and an Energy-Saving Cooling Mode. The unit can be controlled via a wireless remote controller, offering a range of settings and operational modes.
Important Technical Specifications:
- Type: Wall Mounted Air Conditioner
- Power Supply: Uses 2 AAA (1.5 volt) batteries for the wireless remote controller.
- Temperature Settings:
- Cooling: 18°C to 30°C
- Heating: 16°C to 30°C
- Jet Cool: 18°C setting temperature for 30 minutes.
- Jet Heat (available on some models): 30°C setting temperature for 60 minutes.
- Fan Speeds: Four steps: low, medium, high, and CHAOS (natural breeze logic).
- Timer: Programmable in one-hour increments for 1 to 7 hours in Sleep Mode.
- Refrigerant: The manual emphasizes checking the refrigerant type on the product label and warns against mixing air or gas other than the specified refrigerant.
- Electrical Safety: Requires proper grounding, use of correctly rated circuit breakers/fuses, and dedicated circuits. Power cords should not be modified or extended.
Usage Features:
- Wireless Remote Controller: The primary interface for controlling the air conditioner. It features buttons for:
- START/STOP
- OPERATION MODE SELECTION (Cooling, Auto Operation/Changeover, Healthy Dehumidification, Air Circulation)
- ROOM TEMPERATURE SETTING
- INDOOR FAN SPEED SELECTOR (low, medium, high, CHAOS)
- JET COOL (for rapid cooling/heating)
- AUTO SWING (for horizontal vane movement)
- ON/OFF TIMER
- TIME SETTING
- TIMER SET/CANCEL
- SLEEP MODE AUTO
- ENERGY-SAVING COOLING MODE
- ROOM TEMPERATURE CHECKING
- PLASMA (for air purification)
- VERTICAL AIRFLOW DIRECTION CONTROL (optional)
- RESET
- 2nd F (to access blue-printed functions on buttons)
- AUTO CLEAN
- LCD LUMINOSITY (optional)
- Operation Modes:
- Cooling Operation: Sets desired indoor temperature and fan speed.
- Auto Operation/Changeover (Optional): Automatically adjusts operation mode (heating or cooling) to maintain temperature within ±2°C of the setting.
- Healthy Dehumidification Operation: Automatically sets room temperature and airflow for optimal dehumidification, especially in humid seasons. The setting temperature is not displayed or controllable in this mode.
- Air Circulation Mode: Circulates air without cooling or heating, with selectable fan speeds. CHAOS Air mode optimizes power consumption and prevents overcooling by automatically changing fan speed.
- Auto Clean Operation: Removes moisture from indoor units after cooling or dehumidification to prevent mold and odors. The indoor fan runs for about 30 minutes after the unit is turned off.
- PLASMA Purification Operation: Utilizes a plasma filter to generate high-charge electrons, killing and destroying microscopic contaminants for clean and hygienic air. Can be used in any operation mode and with any fan speed.
- Energy-Saving Cooling Mode: Saves energy by adjusting desired temperature based on time and temperature changes for efficient operation.
- Sleep Mode: Automatically stops the unit after a set time (1-7 hours). Operates at slow fan speed in cooling and medium speed in heating for pleasant sleep. In cooling/healthy dehumidification, the setting temperature rises automatically by 2°C over 1 hour for comfort.
- Jet Cool Operation: Provides rapid cooling (18°C, super high fan speed for 30 min) or heating (30°C, super high fan speed for 60 min) for quick temperature adjustments.
- Forced Operation: Allows basic operation (cooling or heating) even without the remote controller by pressing the ON/OFF button on the unit.
- Test Operation: Operates in cooling mode at high fan speed for 18 minutes, primarily for testing purposes.
- Auto Restart Function: Restores previous operating conditions after a power failure.
- Airflow Control:
- Horizontal Vane Control: Adjusts up/down airflow direction manually or automatically via the AUTO SWING button.
- Vertical Vane Control: Adjusts left/right airflow direction manually or automatically via the VERTICAL LOUVER button.
- Time Setting: Allows setting the current time on the remote controller.
Maintenance Features:
- Indoor Unit:
- Cleaning: Use a soft dry cloth. Avoid bleach, abrasives, water hotter than 40°C, or volatile substances.
- Air Filters: Check and clean every 2 weeks or more often. Remove, clean with a vacuum cleaner or warm soapy water (with detergent if needed), dry in shade, and reinstall.
- Plasma Filter: Check and clean every 3 months or more often. Remove, clean with a vacuum cleaner or water, dry in shade, and reinstall. Caution: Do not touch the plasma filter within 10 seconds of opening the inlet grille due to electric shock risk.
- Allergy Free Filter + Triple Filter: Remove and expose to direct sunlight for 2 hours, then reinstall.
- Outdoor Unit:
- Cleaning: Heat exchanger coils and panel vents should be checked regularly. If clogged with dirt or soot, professional steam cleaning is recommended. Dirty coils reduce efficiency.
- Self-Diagnosis Function: The unit has an inbuilt error diagnosis capability, indicated by blinking LEDs. Users are advised to contact a serviceman/dealer in such situations.
- Troubleshooting Tips: Provides a chart for common problems (e.g., unit not starting, not cooling) and their possible causes and solutions (e.g., checking power plug, circuit breaker, air filter, temperature settings, airflow restrictions).
- Service Calls: Advised for abnormal situations like burning smell, loud noise, damaged power cord, error codes, water leaks, or switch/breaker failures. Routine checkups and cleaning are user responsibilities, but special situations require professional service.
