- Location:
- Indoor Unit (Evaporator): Choose a location that allows for even air distribution throughout the room, away from direct sunlight or heat sources. Ensure there is enough space for maintenance and filter cleaning.
- Outdoor Unit (Condenser): Select a well-ventilated area, away from obstacles that could block airflow. Ensure it is placed on a stable, level surface and protected from extreme weather conditions if necessary.
- Room Size Recommendation: The cooling capacity of 12,000 BTUs is generally suitable for rooms between 16 m² and 20 m². Refer to the table below for more detailed guidance based on room size and sun exposure.
| Room Size | Morning Sun | Afternoon Sun or All Day |
|---|---|---|
| Up to 10m² | Up to 7,500 BTUs/h | Up to 7,500 BTUs/h |
| 15m² | 10,000 BTUs/h | 10,000 BTUs/h |
| 20m² | 12,000 BTUs/h | 12,000 BTUs/h |
| 25m² | 12,000 BTUs/h | 15,000 BTUs/h |
| 30m² | 15,000 BTUs/h | 18,000 BTUs/h |
| 40m² | 18,000 BTUs/h | 21,000 BTUs/h |
| 50m² | 21,000 BTUs/h | 30,000 BTUs/h |
Consult with your installation technician to determine the optimal BTU capacity for your specific room conditions.
5. Operating Instructions
Your LG air conditioner is operated primarily using the provided remote control. Ensure the remote control has fresh batteries installed.
5.1 Basic Operation:
- Power On/Off: Press the POWER button to turn the unit on or off.
- Mode Selection: Use the MODE button to cycle through available modes (e.g., Cool, Fan). This model primarily features a Cold cycle.
- Temperature Adjustment: Use the TEMP ▲ / ▼ buttons to set your desired temperature. The operating temperature range is 18°C to 48°C.
- Fan Speed: Adjust the fan speed using the FAN SPEED button.
- Swing Function: Activate the automatic air output (swing) function for even air distribution.
5.2 Advanced Features:
- Active Energy Control: This feature allows you to manage energy consumption. Press the ENERGY CONTROL button on the remote control to cycle through different power consumption levels:
- 100% (Normal operation)
- 80% (Reduced consumption)
- 60% (Further reduced consumption)
- 40% (Maximum energy saving)
Selecting a lower percentage will reduce the unit's power consumption, leading to energy savings, though it may slightly affect cooling performance.

- Open the front panel of the indoor unit.
- Gently remove the air filter(s).
- Clean the filter(s) using a vacuum cleaner or wash them with lukewarm water and a mild detergent.
- Rinse thoroughly and allow the filter(s) to dry completely in a shaded area before reinstalling. Do not expose to direct sunlight.
- Reinstall the dry filter(s) and close the front panel.
6.2 Indoor Unit Cleaning:
- Wipe the indoor unit's exterior with a soft, dry cloth. For stubborn dirt, use a cloth dampened with lukewarm water and a mild detergent, then wipe dry.
- Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the unit's surface.
6.3 Outdoor Unit Cleaning:
The outdoor unit should be inspected and cleaned periodically by a qualified technician to remove dirt, leaves, and other debris that can accumulate on the coils and fan blades, which can impede performance.
