The LG B62AWY-9L6 is a high static reverse cycle ducted air conditioning system designed for very large homes, offices, retail spaces, and commercial buildings that require strong airflow, long duct runs, and flexible zoning. Its high static pressure capability and compact indoor unit make it ideal for demanding ducted installations across multiple rooms and larger open-plan areas. The system includes LG’s PREMTB001 backlit wired wall controller for easy day-to-day operation. With 18.0kW cooling and 20.6kW heating capacity, this model is ideal for very large homes, offices, retail spaces, and areas around 90–130m² depending on insulation and layout. It is designed to deliver strong airflow and stable temperatures across larger zoned systems and longer duct runs.

Key Features & Benefits

High Static Pressure Performance

The system supports strong airflow for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 533 litres per second on high fan speed down to 333 litres per second on low fan speed, helping maintain even air distribution throughout larger homes and commercial spaces.

3-Phase Power Supply

This model operates on 380–415V 3-phase power, making it suitable for larger homes and commercial properties with 3-phase electrical supply. The 3-phase configuration helps spread electrical load more evenly, making it ideal for larger capacity systems.

Energy Efficient Inverter Twin Rotary Compressor

The system uses an inverter twin rotary compressor to automatically adjust output based on room conditions. This helps provide more stable temperatures, quieter operation, and lower running costs compared to fixed-speed systems.

Compact Indoor Unit Design

The indoor unit measures approximately 1320mm wide, 400mm high, and 534mm deep, while the outdoor unit measures approximately 950mm wide, 834mm high, and 330mm deep. Despite its larger capacity, the system remains compact enough for many residential and commercial roof spaces.

Quiet Operation

Indoor sound levels are approximately 41dBA on high fan speed, 40dBA on medium, and 39dBA on low fan speed. Outdoor sound pressure levels are approximately 51dBA in cooling mode and 52dBA in heating mode, helping maintain quieter day-to-day operation for a system of this size.

Zone Control Compatible

The system supports optional zoning for up to eight zones, allowing users to independently control airflow to different areas of the property. This can help improve comfort and reduce unnecessary energy use in unused rooms.

Wi-Fi Smart Control Compatible

The LG ThinQ® app allows remote control of the system through an optional Wi-Fi module, making it easy to adjust temperature, operating mode, and timers from a smartphone.

Backlit Controller Included

The included LG PREMTB001 wired wall controller features a backlit display, timer functions, fan speed adjustment, filter reminders, and simple operating controls for day-to-day use.

Wide Operating Range

The unit can operate in outdoor temperatures from -15°C to 48°C in cooling mode and from -18°C to 18°C in heating mode, making it suitable for Australian climate conditions year-round.

R410A Refrigerant

The system uses R410A refrigerant and comes pre-charged for pipe lengths up to 10 metres. It supports maximum pipe runs of up to 30 metres with a height difference of up to 30 metres between indoor and outdoor units. 5 Year Manufacturer Warranty LG ducted systems include a 5-year manufacturer warranty when installed by a licensed technician in accordance with manufacturer guidelines.
