Installing and connecting the assembly pipe of the indoor unit

Connect indoor and outdoor units with field-supplied copper pipes by means of flare connections. Use insulated seamless refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be used.

There are 2 refrigerant pipes of different diameters:

•The smaller one is for the liquid refrigerant

•The larger one is for the gas refrigerant

A short pipe is already fitted to the air conditioner. You may need to extend the pipe using the assembly pipe (optional).

The connection procedure for the refrigerant pipe varies according to the exit position of the pipe when facing the wall:

• Right(A)

B

• Left(B)

• Underside(C)

• Rear

 

1.Cut out the appropriate knock-out piece (A or B) on the rear of the indoor unit unless you connect the pipe directly from the rear.

2.Smooth the cut edges.

3.Remove the protection caps of the pipes and connect the assembly

pipe to each pipe. Tighten the nuts first with your hands, and then with a torque wrench, applying the following torque:

• If you want to shorten or extend the pipes, refer to page 37~38.

4.Cut off the remaining foam insulation.

5.If necessary, bend the pipe to fit along the bottom of the indoor unit. Then pull it out through the appropriate hole.

The pipe should not project from the rear of the indoor unit.

The bending radius should be 100 mm or more.

7.For further details on how to connect to the outdoor unit and evacuate the air, refer to page 41~43.

• The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test;

refer to page 45 for further details.

• Tighten the flare nut with torque wrench according to specified method.

If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage.

•DO NOT WALL UP THE PIPE CONNECTION !

All refrigerant pipe connection must be easy accessible and serviceable.

AR07JSFPEWQNEU, AR09JSFPEWQNET, AR12JSFPEWQNZE, AR09JSFPEWQNZE, AR12JSFPEWQNET specifications

Samsung has long been a leader in innovative technologies, and their line of air conditioners, including the AR12JSFPEWQNET, AR09JSFPEWQNET, and AR07JSFPEWQNEU, exemplifies this dedication to quality and performance. These models are specifically designed to provide optimum comfort, energy efficiency, and advanced features, making them ideal for home and office environments.

One of the standout features of these Samsung air conditioners is their use of Digital Inverter Technology. This technology ensures that the compressor operates at variable speeds rather than turning on and off frequently. By maintaining a more consistent temperature, this not only enhances comfort but also significantly reduces energy consumption, leading to lower electricity bills. Additionally, the inverter technology contributes to a quieter operation, allowing users to enjoy a peaceful indoor environment.

Another notable technology is the Triple Protection Filter. This specialized filter system effectively captures airborne dust, allergens, and particulate matter, resulting in cleaner and healthier indoor air quality. The filter is also easy to clean and maintain, ensuring that the air conditioning system operates efficiently over time.

These air conditioning units also feature a sleek, modern design that can seamlessly blend into various interior styles. The compact size of the AR07JSFPEWQNEU makes it particularly suitable for smaller spaces, while the AR12JSFPEWQNET and AR09JSFPEWQNET models are designed to cater to larger rooms with more powerful cooling capabilities.

Samsung has also integrated user-friendly controls into these models, providing convenience and ease of operation. With features like the SmartThings app, users can monitor and control their air conditioning units remotely through their smartphones. This means that the air conditioning can be switched on before arriving home, ensuring a comfortable environment upon entering.

Energy efficiency is further enhanced with the Energy Saving Mode, which optimizes performance to reduce unnecessary power draw while maintaining comfort levels.

In conclusion, the Samsung AR12JSFPEWQNET, AR09JSFPEWQNET, and AR07JSFPEWQNEU air conditioners are equipped with cutting-edge technologies and features that make them exceptional choices for effective cooling. With their energy efficiency, advanced filtration systems, and smart controls, they provide both comfort and convenience, reflecting Samsung’s commitment to quality and innovation in home climate solutions.
