Evacuating the connected pipes

1.Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2. Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque.

• Excessive torque can be cause of gas leakage.

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

4.Open the valve of the low pressure side of manifold gauge counterclockwise.

5.Evacuate 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) 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.

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

Adding Refrigerant

Add refrigerant charge according to table below:

If you use a pipe longer than 5 m,

‘A’g of refrigerant R-22 must be added for each extra meter.

If you use a pipe shorter than 5 m,

The evacuating time is normal.

Refer to the Service Manual for further details.

AR18KPFNDWKNSG, AR24KPFNDWKNSG, AR12KPFNDWKXSG, AR12HPFSDWK/SG, AR24KPFNDWK/SG specifications

Samsung's AR series air conditioners, including models AR12KPFNDWKNSG, AR24KPFNDWK/SG, AR12HPFSDWK/SG, AR12KPFNDWKXSG, and AR24KPFNDWKNSG, represent a perfect blend of advanced technology, efficiency, and design, making them a vital component of modern home environments.

One of the standout features of these models is Samsung's Digital Inverter technology. This state-of-the-art system optimizes energy consumption by automatically adjusting the compressor speed depending on the cooling demand. As a result, these air conditioners not only provide powerful cooling when it's needed but also operate quietly and maintain energy efficiency, resulting in lower electricity bills.

Another notable characteristic is the Fast Cooling mode, which allows for rapid temperature adjustments. This is particularly advantageous during the sweltering summer months when immediate relief is desired. The AR series can quickly lower temperatures to provide comfort as soon as you enter the room.

These models also come equipped with Samsung's advanced filtration technology, which plays a significant role in maintaining indoor air quality. The air conditioners are designed with a multi-layer filtration system that traps dust, allergens, and other pollutants, creating a cleaner and healthier environment for occupants. This feature is increasingly essential, particularly for those with allergies or respiratory concerns.

The design of the AR series is sleek and modern, ensuring that they fit seamlessly into any interior decor. The front panel is smooth and simple, often available in neutral colors that allow it to blend effortlessly with various room styles. Furthermore, the compact form factor of these units makes them easy to install without compromising valuable floor space.

In terms of control, these air conditioners are user-friendly. They often come with a remote control for convenient operation from anywhere in the room, as well as smart features that enable control via smartphone apps. This compatibility with smart home systems provides added convenience for tech-savvy users.

Moreover, the models are designed with durability in mind. High-quality components and a robust build ensure that these air conditioners are built to last, handling the rigors of everyday use while minimizing maintenance needs.

In summary, the Samsung AR12KPFNDWKNSG, AR24KPFNDWK/SG, AR12HPFSDWK/SG, AR12KPFNDWKXSG, and AR24KPFNDWKNSG models epitomize modern air conditioning technology. With their efficient performance, advanced filtration, user-friendly controls, and stylish design, they cater to contemporary consumer needs while ensuring comfort and satisfaction.
