NOTE

If you want to shorten or extend the pipes, see Step 2.9 Shortening or extending the refrigerant pipes (assembly pipe) on page 14.

4Cut off the remaining foam insulation.

5If 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.

6Pass the pipe through the hole in the wall.

7Fix the indoor unit on the wall.Pass the cables, pipes and hose through the knock-out hole which would be connected to the outdoor unit .

8Use 2 screws to fix the indoor unit as shown in the picture 2.

9Assemble the Guide into the position of A or B as shown in the picture 3.

NOTE

The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test. For further details. see Step 4.1 Performing the gas leak tests on page 21.

CAUTION

Tighten the flare nut with a torque wrench according to specified method. If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage.

Do not box in or cover the pipe connection. All refrigerant pipe connection must be easily accessible and serviceable.

The Samsung AR09MSPXBWKNEU and its counterparts, the AR12MSPXBWKXEU, AR12MSPXBWKNEU, and AR09MSPXBWKXEU, are part of Samsung’s innovative range of air conditioning units designed for superior performance and energy efficiency. These models represent a combination of sleek design, advanced technology, and user-friendly features, catering to residential and commercial cooling needs.

One of the standout features of these units is their powerful inverter technology. This technology allows the air conditioner to automatically adjust its power based on the room's cooling needs, ensuring consistent temperature levels while minimizing energy consumption. As a result, users benefit from lower electricity bills and a reduced environmental footprint.

Another significant characteristic is the Triple Protector Plus technology. This feature enhances the durability of the units by providing protection against voltage fluctuations, operating without stabilizers, and preventing corrosion on the unit's surface. This ensures that the air conditioners can withstand varying weather conditions and are built to last longer.

The Wind-Free cooling technology further sets these models apart. It enables a comfortable environment by dispersing cool air through micro-holes, creating a gentle breeze without the uncomfortable direct airflow. This results in a more pleasant indoor climate and can contribute to better overall health and comfort for occupants.

In addition, the AR09MSPXBWKNEU and AR12MSPX series are equipped with a user-friendly Smart Things application that allows users to control their air conditioning units remotely. This capability offers convenience and flexibility, enabling scheduling, temperature adjustments, and even monitoring of energy consumption directly from a smartphone.

Furthermore, these models come with easy-to-clean filters that are washable, promoting better air quality by trapping dust and allergens, which can be particularly beneficial for individuals with allergies or respiratory conditions.
