Installation

3Open the valve of the low pressure side of manifold gauge anticlockwise.

4Evacuate the air in the connected pipes using the vacuum pump for about 15 minutes.

Make sure that pressure gauge shows -0.1 MPa (-76 cmHg, 5 torr) after about 10 minutes. This procedure is very important to avoid a gas leak.

Close the valve of the low pressure side of manifold gauge clockwise.

Turn off the vacuum pump.

Check for 2 minutes if there is any pressure change.

Remove the hose of the low pressure side of manifold gauge.

5Set a valve cork of liquid and gas service port to the open position.

Step 3.4 Adding refrigerant

If you use a pipe longer than the length specified in the piping codes and standards, you must add 20g of refrigerant R-410A for each extra meter. If you use a pipe shorter than the length specified in the piping codes and standards, the evacuating time is normal.

Refer to the Service Manual for further details.

CAUTION

The remaining air in the Refrigeration cycle, which contains moisture, may cause malfunction on the compressor.

Always contact the service centre or a professional installation agency for product installation.

R-410A is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid. When recharging refrigerant from the refrigerant cylinder to the equipment.

Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the

refrigerant:

NOTE

If R-410A refrigerant is charged with gas, the composition of the charged refrigerant changes and the characteristics of the equipment vary.

During the measuring operation of refrigerant quantity added use electronic scales. If cylinder doesn't have siphon, upset it.

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.
