Dual Inverter compressor guaranteed for 10 years

 Garanzia 10 anni

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 in this catalogue.

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.

LG Multisplit Systems

LG is among the most important companies in the world for the production of air conditioners.
The range of MULTISPLIT products is characterized by high flexibility, very high energy efficiency and low noise levels.
Multisplit solutions allow you to address both the needs of small residential systems and the needs of commercial spaces.

Quality and Safety Guarantee

LG is extremely attentive to the quality of its products and environmental issues. LG offers on its air conditioners, in addition to the 24-month legal guarantee, an additional 3-year guarantee on compressors, an exclusive formula to let you choose fully
safety. All LG air conditioners have obtained the most important international quality and safety certifications.
All LG air conditioners are made with environmentally friendly technologies and use R-410A refrigerant which does not produce deleterious effects on the ozone layer. The high energy efficiency that characterizes them helps to reduce CO2 emissions.
LG adheres to collective collection systems that guarantee a completely safe disposal service for end-of-life products.

Seasonal energy efficiency
The outdoor units of the new multi-pipe Multi range are characterized by seasonal energy efficiency levels already in line with the European standards in force starting from 2014. The SEER level is higher than 6.10 and will allow these products to obtain the A++ classification for their seasonal cooling energy efficiency. The new Multi range with multiple pipes allows you to reduce energy consumption by 37% (average) compared to the previous series. Multi outdoor units are characterized by extremely high levels of energy efficiency. Thanks to this assumption they contribute very significantly to the reduction of carbon dioxide emissions.
Wide Louver heat exchanger
Thanks to this assumption they contribute very significantly to the reduction of carbon dioxide emissions
The heat exchanger with Wide Louver fins is applied to the external units. The particular processing of the fins allows the exchange capacity of the radiator to be improved by 28% with the same surface area compared to a traditional exchanger.
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
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 important reductions in
electrical current absorbed.
Wiring error checking function
Thanks to this function, at the end of the installation work it is possible to verify that the electrical and piping connections are correctly associated. Through this control function, which can be activated from the external unit's electronic board, it is possible to achieve a correct and perfectly functioning installation quickly and easily.
Reduced electricity consumption in Stand-by
An innovative function allows the electrical power supply to the system components to be removed during the stand-by phase of the system. In this way, the stand-by electricity consumption of the new multi-pipe Multi outdoor units is 90% lower than the previous versions.

Reduced sound level

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.

LG Atmosphere Clean and fresh

LG air conditioners are characterized by a 2-in-1 purification system (air cooling and filtration) capable of filtering fine dust, germs and pollutants such as PM 1.0.


4-color smart display

The PM 1.0 sensor detects ultra-fine dust in real time and shows the air quality level in 4 different colors


Energy saving

Inverter technology is able to modulate the power supplied based on actual needs; this allows you to keep the temperature constant, avoiding energy waste, in favor of greater efficiency and maximum energy savings

Fast cooling

A wider and perfectly designed air flow allows you to reach even the furthest corners and cool the room more quickly.

Check how much energy you consume

The slim and modern designs of LG air conditioners make installation easier and cleaning the product more convenient thanks to the EZ sliding filters. Furthermore, the pop-up display is perfect for conveniently controlling the energy 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.

Massima silenziosità

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.

Facile Installazione

• Perfect adhesion to the wall

• Greater space for piping

• Installation plate with anchoring screws

• Removable bottom panel

• Lifting clip

6-step vertical flow control

You can choose from 6 preset positions that meet your different needs in terms of air flow direction.

Car Cleaning

The efficient Auto Cleaning function prevents the formation of bacteria and mold on the heat exchanger, creating a more pleasant and comfortable environment.
