The LG UBN36R is a slim reverse cycle ducted air conditioning system designed for homes, apartments, and offices where ceiling space is limited. Its compact low-profile indoor unit makes it ideal for shallow roof cavities, narrow bulkheads, and tighter ceiling spaces while still delivering strong whole-home heating and cooling performance. With 9.5kW cooling and 10.8kW heating capacity, this model is ideal for larger open-plan living areas, medium to large homes, offices, and spaces around 45–70m² depending on insulation and layout. The system can modulate from 4.5kW up to 13.0kW in cooling mode and from 5.0kW up to 13.7kW in heating mode, helping maintain more stable temperatures while reducing running costs.

Key Features & Benefits

Slim Low Profile Indoor Unit

The indoor unit measures approximately 270mm high, 1250mm wide, and 700mm deep, making it ideal for installations where roof space is limited. Despite its slim design, it still provides strong airflow performance for larger homes and multiple rooms.

Mid Static Pressure Performance

The system uses LG’s E.S.P. (External Static Pressure) Control, allowing installers to adjust airflow using the controller without additional accessories. The BLDC fan motor helps maintain more consistent airflow regardless of duct resistance or static pressure.

Strong Airflow Performance

The larger chassis and variable fan control help deliver strong airflow across multiple rooms and open-plan areas. This makes the UBN36R suitable for homes with longer duct runs and multiple outlets.

Single-Phase Power Supply

This model operates on standard 220–240V single-phase power, making it suitable for most residential properties without requiring a 3-phase electrical upgrade. Rated running current is approximately 10.8 amps in cooling mode and 12.7 amps in heating mode.

Energy Efficient Inverter Technology

The system uses LG inverter technology to automatically adjust compressor speed based on room conditions, helping maintain more consistent temperatures and lower running costs compared to fixed-speed systems. It delivers an EER of approximately 3.91 and a COP of approximately 3.79.

Quiet Operation

Indoor sound levels are approximately 36dBA on high fan speed, 34dBA on medium, and 33dBA on low fan speed. Outdoor sound levels are approximately 52dBA in cooling mode and 54dBA in heating mode, helping maintain quieter day-to-day performance.

Wi-Fi Smart Control Compatible

The system is compatible with LG ThinQ® smart control through an optional Wi-Fi dongle module, allowing users to remotely control temperature, operating modes, and timers from their smartphone.

High Head Drain Pump Compatible

The optional high head drain pump accessory can automatically drain water up to 700mm, helping simplify drainage in tighter ceiling cavities and difficult installation areas.

Zone Control Compatible

The system supports optional zone control for up to eight zones, allowing users to independently manage airflow to different areas of the home for improved comfort and energy savings.

R32 Refrigerant

The system uses modern R32 refrigerant, which provides improved efficiency and lower environmental impact compared to older refrigerants.

Ideal Applications

• Apartments
• Townhouses
• Medium to large homes
• Open-plan living areas
• Offices
• Properties with limited ceiling space
• Zoned ducted systems
