General characteristics


With LG Multi Split systems, you don't need to purchase multiple outdoor units to air condition all the rooms in your home. All you need to do is install a single unit to have the optimal climate in 9 different environments. LG's cutting-edge technologies achieve the lowest energy consumption, in particular the SEER rating regarding ErP regulation is positive.

Style and design

With their design, LG internal units embellish environments: choose the inimitable style of Artcool Gallery and Artcool Mirror to give a unique touch to your home.

BLDC (Brushless Direct Current Motor) Compressor

The outdoor units of the Multi range are equipped with BLDC compressors equipped with motors with neodymium magnets. These compressors are characterized by higher energy efficiency than traditional inverter compressors, and operate optimally in all rotation conditions. This guarantees high seasonal energy efficiency values .

The components of the BLDC Inverter Twin Rotary compressor have been improved to ensure a longer product life cycle.

Smart Load Control

  • Energy saving at start-up By choosing the Smart Load Control function via the outdoor unit micro-switches, the refrigerant temperatures on the heat exchangers are automatically changed based on the outdoor temperature and the set room temperature. During the first 30 minutes of operation, it is possible to achieve energy savings of up to 35% compared to traditional products, also improving the perceived level of comfort. This function allows you to keep the maximum electrical consumption of the outdoor unit within a pre-established limit, to avoid automatic disconnection of the meter or to limit absorption.
  • Energy saving during operation After 30 minutes from start-up in Smart Load Control mode, the outdoor unit continues to modify the temperature of the refrigerated unit according to the thermal load.

Inverter compressor guaranteed for 10 years

LG, which places great trust in the quality and reliability of its products, offers a 10-year warranty on the Inverter compressor of all mono and multi-split models.

*The aforementioned warranty covers the costs of the Inverter compressor part only for a total period of 10 years from the date of purchase of the air conditioner. Any other cost other than the value of the replaced component alone is to be considered excluded from coverage.

Safety and Durability Assured
- Optimized BLDC Inverter Twin Rotary Compressor
- Pressure controlled operation via Smart Sensor
- Black Fin heat exchanger

Other characteristics..

Wide Louver Plus Fin heat exchanger

The Wide Louver Plus Fin heat exchanger is applied to the outdoor units. The particular configuration of the fins allows the exchange capacity of the radiator to be significantly improved compared to a traditional exchanger, up to 11% at full load and up to 6% in terms of COP.

Wide operating range

The outdoor units in the Multi Pipe range can operate in cooling and heating modes in the most extreme conditions. The presence of the condensation control for the cooling mode as standard equipment makes them compatible with all applications where it is necessary to refresh the air even at low external temperatures (e.g. restaurants, gyms, server rooms).

Pressure controlled operation
via Smart Sensor

The new units in the Multi multiple pipe range operate with a control based on the pressures of the refrigerant in the circuit: this type of control ensures better management of the peripherals contained in the units compared to traditional temperature controls. This control mechanism is more precise and refined, without being negatively affected by external temperature variations. The new technology applied to these products allows the desired results to be obtained in shorter times, to better manage the operation of the compressor at partial load conditions, and to achieve significant reductions in the electrical current absorbed.

Black Fin heat exchanger

The black coating with reinforced epoxy resin is applied to ensure protection from various corrosive external conditions such as salt contamination and air pollution, including factory exhaust fumes. Additionally, the hydrophilic film prevents water from accumulating on the heat exchanger fin, minimizing moisture buildup and further increasing corrosion resistance.

Noise reduction mode

Thanks to a series of settings applicable to the units via the electronic board, it is possible to reduce the noise of the external units at night, to the benefit of the comfort and liveability of residential complexes. The adoption of a new fan protection grille and the use of fans with details specifically designed for aerodynamic optimization have allowed a reduction in the noise level of the external units in the order of approximately 2 dB(A) at nominal conditions of detection.

Energy saving

The inverter compressor constantly adjusts the rotation speed to maintain the desired temperature level. Furthermore, the DUAL Inverter compressor, thanks to its energy saving features, allows you to reduce energy consumption compared to a traditional compressor

The Dual Inverter compressor allows stable and balanced operation, with a consequent reduction in vibrations when starting and stopping the air conditioner, the main cause of noise. This also reduces the possibility of any breakage or damage to the pipes.

Fast cooling

The low temperature air jet reaches every corner of the room, making the environment comfortable and welcoming.

How does it work:

A 25% larger fan emits more powerful air blasts. A wider and perfectly designed flow of fresh air allows you to reach even the furthest corners and cool the room more quickly.

Smart Energy Display


Save energy by monitoring the consumption level directly from the indoor unit display and enjoy fresh and comfortable environments while saving.

How does it work

By pressing the 'ENERGY CTRL' button on the remote control, the indoor unit display shows the instant energy consumption, allowing the user to be informed about the consumption of the product and to change, if necessary, the settings to reduce electrical absorption


- in normal mode, the display shows the operating temperature

- Electrical consumption, The display shows the instantaneous electric current absorbed

Additional benefits

- Fan speed display

Maximum silence

LG air conditioners ensure reduced noise thanks to the special Skew Fan and the Inverter compressor, which eliminate unnecessary noise and allow the product to operate as silently as possible.

Skew Fans - The fans of the internal units are made with the use of blades inclined with respect to the axis of rotation, in order to reduce friction with the air, which causes noise

Low vibration Twin Rotary Compressor - The adoption of two opposing rotors in the compressor cylinders allows the torque to be reduced by 40% compared to traditional rotary compressors. The double rotor ensures stability and minimizes vibrations.

Active control of capabilities

The Active Capacity Control function allows you to select the level of energy consumption based on the usage situation. Enjoy a fresh and comfortable energy-saving environment.

Concept and Advantages

Simultaneous operation of multiple household appliances could cause the meter to come off. With the Active Capacity Control function you can take advantage of the 4-step consumption control system and use multiple appliances at the same time, remaining within the standard capacity of 3kWh

2 levels of energy consumption (80% and 60% compared to normal operating conditions), settable via infrared command.


LG air conditioners cool rooms quickly and effectively, to allow you to enjoy fresh and comfortable environments for longer


During the night, the air conditioner can lower body temperature and cause discomfort for people in the room, especially if the air blows directly on them. In order to avoid this, the Comfort Air mode adjusts the angle of inclination of the deflector and ensures a peaceful sleep.

The Comfort Air function regulates the inclination of the deflector, avoiding direct flows towards people present in the room.

Easy installation

LG air conditioners are designed to be installed simply and efficiently, regardless of the environment in which they are placed and the number of people involved in the installation process, allowing a reduction in installation times.
