Step 3.3 Evacuating the air

The outdoor unit is loaded with sufficient R-410A refrigerant. Do not vent R-410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 2088. You should evacuate the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction

of cooling capacity and malfunction. Use a vacuum pump.

CAUTION

When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the stop valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.

1Leave the system in the standby mode.

WARNING

Do not turn on the system! This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve).

2Connect the charging hose of the low pressure side of manifold gauge to a gas service port as seen in the picture.

AR24MRFHRWKNMG, AR24MQFHRWK/MG, AR24KQFHRWKNMG, AR18MRFHCWKNMG, AR18MQFHCWKNMG specifications

The Samsung AR24MRFHRWK/MG, AR24MRFHRWKXMG, AR24KRFHRWKNMG, AR24MQFHRWKNMG, and AR24KRFHRWK/MG are part of Samsung's innovative line of air conditioning units designed to deliver optimal cooling and heating performance. These models cater to diverse consumer needs, featuring advanced technology, energy efficiency, and user-friendly designs.

One of the standout features of these air conditioning units is the Digital Inverter Technology. This technology allows the compressor to operate at variable speeds, significantly reducing energy consumption while maintaining a consistent temperature. Unlike traditional air conditioners that frequently turn on and off, the inverter compressors adjust their speed according to the cooling demand. This not only saves energy but also enhances the lifespan of the unit.

These models also emphasize air quality through a multi-stage filtration system. The filters effectively capture dust, allergens, and other particles, ensuring that the air circulated within the room is clean and healthy. The long-lasting filters are designed for ease of maintenance, allowing users to replace or clean them with minimal effort.

Moreover, the cooling efficiency is backed by a range of features aimed at enhancing comfort. The models come with a fast cooling mode that allows users to achieve desired temperatures quickly, ideal for those hot summer days. Additionally, the units are equipped with a Quiet Mode, ensuring minimal noise levels, making them suitable for use in bedrooms or workplaces.

Energy efficiency is a key characteristic of the Samsung AR24 series. With a high Energy Efficiency Ratio (EER) and seasonal energy efficiency ratings, these models not only lower energy bills but also contribute to a reduced environmental impact.

Smart technology integration is another compelling aspect of these units. Users can control their air conditioning systems remotely via smartphone applications, allowing for temperature adjustments and scheduling from anywhere. This feature enhances convenience and ensures that spaces are pre-cooled or heated before arriving home.

Further enhancing user experience, the sleek design of these models ensures they fit seamlessly into modern interiors. Their compact and stylish appearance makes them a visually appealing addition to any space, whether residential or commercial.

In summary, the Samsung AR24 series showcases advanced air conditioning technology combined with energy efficiency, ease of use, and superior air quality features, establishing it as an excellent choice for consumers looking for reliable and stylish climate control solutions.
