When performing electrical and earthing works, be sure to comply with the 'technical standards of electrical installations' and the 'wiring regulations' in the local regulations.

Tighten the terminal block screw to 1.2-1.8 N•m (1.2-1.8 kgf•cm).

NOTE

Each wire is labelled with the corresponding terminal number.

Use shield cable (Category 5; less than 50pF/m) for noisy environmental site.

Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. (Code designation IEC: 60245 IEC66/CENELEC: H07RN-F, IEC: 60245 IEC57 CENELEC: H05RN-F, IEC: 60227 IEC53: H05VV-F)

Power & Communication cable shall not exceed 30m.

CAUTION

For the terminal block wiring, use a wire with a ring terminal socket only. Regular wires without a ring terminal socket may become a hazard due to overheating of the electrical contact during installation.

If you need to extend the pipe, be sure to extend the cable, too.

Do not connect two or more different cables to extend the length. This connection may cause fire.

Each circular terminal must match the size of its corresponding screw in the terminal block.

After connecting the cables, make sure that terminal numbers on the indoor and outdoor units match.

Ensure that power and communication cables are separated, they must not be in the same cable.

AR09MSPXAWKXEU, AR12MSWXBWKNEU, AR12MSPXASIXEU, AR09MSPXASIXEU, AR07MSWXBWKNEU specifications

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.

Lastly, the modern and minimalist design of the Samsung air conditioning units ensures that they seamlessly blend into any interior decor, making them not just functional appliances but also aesthetic additions to the space.

In summary, Samsung’s AR09MSPXBWKNEU, AR12MSPXBWKXEU, AR12MSPXBWKNEU, and AR09MSPXBWKXEU air conditioners showcase cutting-edge technology, robust features, and energy efficiency, making them excellent options for consumers looking to enhance their indoor climate conditions.
