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.

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.

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.

AR12HSSDPWKNEE, AR09HSSDPWKNEE specifications

The Samsung AR09HSSDPWKNEE and AR12HSSDPWKNEE are part of Samsung's high-efficiency air conditioning lineup, designed to provide superior comfort while ensuring energy savings. These models are particularly popular for their advanced technologies and user-friendly features, making them ideal for residential and small commercial spaces.

One of the standout features of both models is the Digital Inverter Technology. This innovative technology maintains the desired temperature without the constant on-and-off cycling typical of conventional air conditioning units. As a result, these units provide a more stable cooling experience, while significantly reducing energy consumption. The Digital Inverter also helps in minimizing wear and tear, leading to increased lifespan and reduced maintenance needs.

The AR09HSSDPWKNEE and AR12HSSDPWKNEE are equipped with the Triple Protector Plus technology, which offers enhanced durability and reliability. This feature protects the compressor and provides safety against voltage fluctuations. Additionally, the units are designed to operate in extreme weather conditions, ensuring consistent performance even in high temperatures or low-voltage situations.

Another notable feature is the Fast Cooling mode. This allows the air conditioner to cool the room quickly to the desired temperature, making it incredibly convenient during hot weather. The units also come with a Quiet Mode, which minimizes noise levels, making them suitable for bedrooms or quiet spaces.

Energy efficiency is a critical characteristic of these models. With high energy efficiency ratings, they help in lowering electricity bills while being environmentally friendly. The units are also designed to be eco-conscious, with R32 refrigerant, which has a lower global warming potential than traditional refrigerants.

In terms of user interface, the AR09HSSDPWKNEE and AR12HSSDPWKNEE come with a sleek and intuitive remote control, allowing users to manage settings conveniently from anywhere in the room. Additionally, they feature a filtration system that improves indoor air quality by removing dust and allergens, creating a healthier living environment.

Overall, the Samsung AR09HSSDPWKNEE and AR12HSSDPWKNEE air conditioners combine cutting-edge technology, efficiency, and user-friendly features, making them an excellent choice for anyone looking to enhance their home’s comfort while keeping energy costs in check.
