This document is the owner's manual for an LG Room Air Conditioner (Convertible Type), providing comprehensive information on its operation, maintenance, and troubleshooting.
Function Description:
The LG Room Air Conditioner is designed to provide cooling, heating (for heat pump models), and dehumidification for indoor spaces. It features various operation modes, including Cooling, Auto, Soft Dry, and Heating, allowing users to select the most suitable setting for their comfort. The "Convertible Type" designation suggests flexibility in installation or usage, though specific details on this convertibility are not explicitly detailed in the provided pages. The unit is controlled via a remote control that transmits signals to the system, enabling users to adjust settings from a distance.
Important Technical Specifications:
While detailed technical specifications like power consumption or BTU ratings are not fully available in the provided pages, some key operational parameters and model information are present:
- Temperature Range: The room temperature can be set within a range of 18°C to 30°C in 1°C increments for Cooling and Soft Dry modes, and 16°C to 30°C in 1°C increments for Heating mode.
- Fan Speed: The indoor fan speed can be selected in four steps: low, medium, high, or CHAOS mode. CHAOS Air mode is designed to economize power consumption and prevent overcooling by automatically changing fan speed based on ambient temperature, simulating a natural breeze.
- Timer Functions: The unit supports ON/OFF Timer operations, allowing users to set specific start and stop times. A Sleep Mode Auto button enables setting the unit to turn off automatically after 1 to 7 hours, with temperature adjustments for comfortable sleeping (1°C rise in 30 minutes, 2°C rise in 1 hour in cooling mode).
- Auto Restart: In case of a power failure, the Auto Restarting Operation function automatically resumes the previous operating conditions once power is restored.
- Safety Norm: Prior to installation, the unit must be submitted for approval by the utility service providing electricity, adhering to the EN 60555-3 Norm.
- Model Weight (Indoor/Outdoor):
- Cooling Model:
- LV-B18**C*: Indoor 30kg, Outdoor 55kg
- LV-B24**C*: Indoor 30kg, Outdoor 60kg
- Heat Pump Model:
- LV-B18**H*: Indoor 30kg, Outdoor 60kg
- LV-B24**H*: Indoor 30kg, Outdoor 62kg
- Remote Control Range: The remote control operates the air conditioner at a distance of up to 7m.
- Batteries: The remote control uses 2 AAA (1.5volt) batteries.
Usage Features:
- Remote Control: The primary interface for controlling the air conditioner. It features buttons for Start/Stop, Operation Mode Selection, Room Temperature Setting, Indoor Fan Speed Selector, Air Flow Direction, Sleep Mode Auto, Air Circulation, Room Temperature Checking, Time Setting, and Timer Set/Cancel. The remote has a flip-up door that covers some buttons when closed.
- Operation Modes:
- Cooling Operation: Sets the unit to cool the room.
- Auto Operation: Automatically sets temperature and fan speed based on room temperature. Users can make minor adjustments to the set temperature.
- Soft Dry Operation: Designed for dehumidification, automatically switching to low fan speed.
- Heating Operation (Heat Pump Model): Sets the unit to heat the room.
- Airflow Direction Control:
- Vertical Airflow: Adjustable up/down via the Chaos Swing button on the remote. Manual adjustment is discouraged to prevent damage.
- Horizontal Airflow: Adjustable left/right manually, but only when the unit is turned off and the vertical louver is open.
- Air Circulation Mode: Circulates room air without cooling or heating, with adjustable fan speeds.
- Forced Operation: A backup operation mode for when the remote control is unavailable. It sets predefined operating conditions (e.g., Cooling, High fan speed, 22°C setting temperature for room temp ≥ 24°C).
- Sleep Mode: Automatically adjusts temperature and turns off after a set period (1-7 hours) for comfortable sleep.
- Timer Setting: Allows scheduling of ON/OFF operations.
- Room Temperature Checking: A dedicated button on the remote to check the current room temperature.
Maintenance Features:
- Air Filter Cleaning: The air filters, located behind the front grille of the indoor unit, should be checked and cleaned every 2 weeks or more often if necessary. Cleaning involves removing the filter, washing it with a vacuum or warm, soapy water (lukewarm water with detergent for conspicuous dirt), drying it in the shade, and re-installing. Hot water (50°C or more) should be avoided as it can deform the filter.
- Indoor Unit Cleaning: The grille, case, and remote control should be wiped with a soft, dry cloth. Harsh chemicals, water hotter than 40°C, or volatile substances should not be used as they can cause deformation, discoloration, or damage. The main power supply must be disconnected before cleaning the indoor unit.
- Outdoor Unit Cleaning: The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, they should be professionally steam cleaned. Blockages reduce efficiency and increase operating costs.
- Long-Term Storage: If the air conditioner will not be used for a long time, it is recommended to operate it on Air Circulation mode for 2 to 3 hours to dry internal parts, then turn off the circuit breaker and remove batteries from the remote control.
- Pre-Use Check (After Storage): Before using the unit again, clean and re-install the air filter, and ensure the air inlet and outlet of both indoor and outdoor units are not blocked.
- Regular Ventilation: It is advised to ventilate the room occasionally, especially since windows are often kept closed during air conditioner operation.
- Air Filter Regular Cleaning: Regular cleaning of the air filter (at least once every two weeks) is crucial to maintain airflow and cooling/dehumidifying efficiency.
