Air conditioner Lessar Cool+ Inverter R32 LS-H18KFE2/LU-H18KFE2 18000 BTU

Lessar Cool+ LS-H18KFE2/LU-H18KFE2 18000 BTU is a powerful wall-mounted air conditioner designed to maintain a comfortable indoor climate in spacious residential and commercial premises. The model can be installed in a large living room, studio apartment, office, shop, salon, café, or another room with an approximate area of up to 45–50 m². The COOL+ series combines an affordable price, reliable construction, high energy efficiency, and a convenient selection of modes for everyday use.

The stated coverage area is approximate. When selecting an air conditioner, it is important to consider the ceiling height, building insulation, window size and orientation, number of people, operating equipment, and other heat sources. A professional capacity calculation is recommended for rooms with panoramic glazing, high ceilings, or intensive visitor traffic.

Efficient operation in a spacious room

The Lessar Cool+ 18000 BTU capacity allows the room temperature to be lowered quickly during hot weather. In cooling mode, the air conditioner operates until the selected value is reached and then maintains comfortable conditions. During transitional seasons, the model can be used in heating mode as an additional heat source.

Automatic mode simplifies operation: the air conditioner analyses the current temperature and selects a suitable operating algorithm. Ventilation mode circulates the air without starting the compressor. Several fan speeds allow users to select the airflow intensity — from powerful airflow for rapid cooling to gentler air distribution.

Dehumidification mode can be activated when humidity is high. It helps reduce the feeling of dampness and create a more comfortable indoor climate without a sudden drop in temperature. This function is particularly useful on rainy days, during transitional seasons, and in rooms with insufficient natural ventilation.

Automatic vertical louvre swing helps distribute air evenly. Users can select one of the fixed positions or activate smooth louvre movement to direct the airflow towards different areas of a spacious room.

Settings for comfortable rest

Night mode follows a special temperature programme, creating suitable conditions for sleep and reducing the likelihood of excessive cooling. This function is useful when the air conditioner is installed in a bedroom, studio apartment, or hotel room.

The 24-hour timer allows the split system to be programmed in advance to turn on and off. For example, the air conditioner can begin cooling an office before employees arrive or stop automatically after a shop closes. All functions and settings are controlled using the infrared remote control.

The automatic restart function saves the latest settings during a temporary power outage. Once power is restored, the air conditioner automatically resumes operation in the previously selected mode.

When heating mode is used, the “Smart Start” function delays the indoor unit fan until the heat exchanger has warmed up. This prevents cold air from entering the room. Automatic defrosting removes ice from the outdoor unit’s heat exchanger, maintaining system efficiency in cool weather.

Reliable compressor and protective functions

The split system uses a reliable GMCC rotary compressor designed for prolonged operation. The compressor start-delay function equalises the refrigerant pressure and reduces starting currents. This lowers the load on key components and helps extend the equipment’s service life.

The self-diagnostic system continuously monitors the operating parameters and condition of the air conditioner units. If deviations are detected, it helps identify the nature of the fault and simplifies subsequent technical maintenance. Refrigerant quantity monitoring allows an insufficient level to be detected promptly and helps prevent possible equipment damage.

Despite its increased output, the indoor unit features a clean design. Its pleasant light shade, well-defined geometric shape, and neat lines allow the Lessar Cool+ LS-H18KFE2/LU-H18KFE2 to blend harmoniously into an apartment, office, or commercial interior.

The Lessar Cool+ Inverter R32 18000 BTU air conditioner is suitable for customers who need a high-performance, functional climate-control system at an affordable price. The model provides cooling, heating, ventilation, and dehumidification, supports automatic airflow distribution, and includes functions for reliable operation.
