The split system under consideration consists of two blocks:

1. Indoor module, which is intended to be installed indoors, has the shape of an elongated rectangle made of durable, shiny, high-quality plastic. The dimensions of the block are 722*290*187 mm, weight – 7.8 kg.
2. External device – a rectangular “box” with parameters and weight 700*550*270 mm/26 kg – mounted outdoors. The module is covered with an anti-corrosion, moisture-resistant coating, which allows it to withstand precipitation well, maintaining functionality for many years.

A line is laid between the devices, which includes a drain pipe, a hose for supplying refrigerant, and electrical cables.The track has a maximum length of 20 m, and the permissible height difference for this model is 8 m.

The remote control comes with a special case that can be mounted on a wall or other surface, which increases the level of comfort in using the equipment.

The split system also includes an infrared remote control Intelligence, designed to control basic modes and other functions: raising/lowering the temperature, setting a timer, enabling additional settings, and so on.

The execution of commands is accompanied by a sound signal, which can be turned off if desired. The remote control has a yellow-orange backlight, making it convenient to use even in the dark.

If the remote control is unavailable, it is possible to control the device using a button located on the indoor unit: in this case, the mode can be turned on AUTO.

Main technical specifications

Although the split system uses a conventional motor rather than an inverter, its high-tech design contributes to economical electricity consumption. The power consumption for cooling is 0.822 kW and 0.812 kW for heating.

Detailed information about the differences between an inverter split and a conventional split is given in this article.

Other fundamental characteristics include:

• cooling capacity – 2.63 kW;
• heating capacity – 2.93 kW;
• maximum air flow speed – 7.55 m³/min;
• serviced area – up to 27 square meters.

The device operates in cooling mode in the temperature range +18 ∼+43 °C; when heating from –7 to +24°C.

It is possible to combine the model with a special kit that allows you to use the technology Winter Master. In this case, the split system will operate in cooling mode until the outside temperature reaches –43°C.

The model has a flexible installation system, thanks to which the indoor unit can be connected from different sides. This provides greater freedom of choice when placing the air conditioner

The low noise level of the unit in question, varying from 26 to 36 dB, attracts attention. The lower limit of the range is typical when the device is operating in the most economical, night mode.

Split system functionality

Despite the fact that the device belongs to the Economy class, which implies a minimum number of functions, the device has all the necessary settings to ensure efficient operation and comfortable use.

Basic air conditioner modes

The LESSAR LS H09KPA2 device can operate in four main modes, namely:

• heat the air;
• cool the room;
• dry, removing excess moisture;
• ventilate the space without decreasing/increasing the temperature.

There are also two additional modes with preset settings. By default, the unit operates in automatic mode, which assumes the most comfortable temperature at +22∼23°C.

It is recommended to install it during sleep "night mode", which is characterized by a decrease t air by 2°C, reduced noise levels, reduced electricity consumption.

Comfort features

For user convenience, the following options are provided:

• timer;
• smart start;
• automatic swing of blinds;
• auto restart;
• changing the rotation speed of the ventilation blades.

Timer allows you to program in advance the exact time to turn on/off the device for a daily period.The selected values ​​are set using the remote control.

The split system kit includes instructions in Russian, which contain comprehensive information about installation, operation and safety measures. Please note that a number of functions mentioned in the manual are not available for the LS H09KPA2 model

Smart start — the option prevents the supply of cold air to the room if the device is turned on in heating mode.

Automatic swing of blinds — the function involves automatic movement of the flaps up and down, which allows you to change the direction of the air flow. The smooth oscillation of the blinds contributes to the uniform distribution of the treated air masses within the room.

Autorestart allows you to save the last settings set by the user for the air conditioner. If the electricity suddenly goes out and then turns on again, the air conditioner will automatically continue to operate in the previously set mode.

In the model, it is possible to select three options for the rotation speed of the ventilation blades: low, medium and high. Thanks to this, you can control the level of air flow, choosing the most comfortable option.

System protective functions

For reliable operation of the device, it provides a number of important options, namely:

• refrigerant content control;
• compressor start delay;
• auto defrost;
• self-diagnosis.

Refrigerant level control. The option is aimed at monitoring the amount of refrigerant in the system, thereby reducing the risk of equipment failure.

The manufacturer strongly recommends that maintenance be performed twice a year by qualified personnel.This procedure includes both complete cleaning of system parts and monitoring of system operation

Compressor start delay. The option helps equalize the refrigerant pressure in the system and reduce starting currents. This reduces the load on the motor, which contributes to its uniform, stable operation and increased service life.

Auto-freeze prevents the formation of ice crystals on the external unit. At the first sign, the compressor automatically turns off and the heating mode begins to operate.

After complete cleaning of the surface, during which the formation of steam and water droplets may be observed, the device again begins to operate according to the previously specified settings.

Device self-diagnosis. The design of the device includes a special microprocessor, the task of which is to monitor operating modes, as well as the state of the system blocks.

If malfunctions are detected, information is displayed on the display. Often this allows air conditioner owners to correct the situation on their own.

Despite the fact that the attached instructions discuss in detail the process of installing indoor/outdoor units, the manufacturer advises using the services of professionals for installation work

For stable operation and long service life of the air conditioner, you must strictly follow the instructions supplied with the system. For example, you must not block the air intake and outlet openings or place the device near heat sources.
