Performing the gas leak tests

Make sure to check for gas leaks before completing the installation process (connecting the assembly pipe and hose between indoor unit and outdoor unit, insulating the cables, hose and pipe, and fixing the indoor unit to the installation plate).

Before inspecting the leakage, use a torque wrench to close the cap for the service valve. (Comply with a tightening torque for each size of the diameter,and tighten the cap firmly to prevent any leakage.).

To check for any possible leakage, insert inert gas into the pipes connected to indoor/outdoor units and check the connection part of the indoor/outdoor units with soap lather or liquid for leakage test.

To check for gas leaks on the outdoor unit,

( 1 N•m = 10 kgf•cm )

Check the valve A and B using a leak detector.

 

To check for gas leaks on the indoor unit,

 

Check the flare nut C and D using a leak detector.

 

Leak test with nitrogen (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-22.

Leak test (after opening valves)

Before opening valves, discharge all the nitrogen from the system and create vacuum according to page 47~48. After opening valves, check leaks using a leak detector for refrigerant.

Pump down (before disconnecting the refrigerant connections for unit repair, removal or disposal) Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit.

This operation must be carried out before disconnecting the refrigerant tubing in order to avoid refrigerant loss to the atmosphere.

Shut off the liquid valve with the Allen wrench.

Turn the system on in cooling with fan operating at high velocity.

(Compressor will immediately start, provided 3 minutes have elapsed since the last stop).

After 2 minutes of operation, shut the suction valve with the same wrench.

Turn the system off and switch mains supply off.

Disconnect tubing. After disconnection, protect valves and tubing ends from dust.

Compressor damage may occur if run at a negative suction pressure.

AR24HPSDBWKNMG, AR24HCSDBWKXMG, AR18HPSDBWKXMG, AR18HCSDBWKNMG, AR18HPSDBWKNMG specifications

Samsung has long been a leader in home appliances and HVAC solutions, and their range of air conditioners, including the AR18HCSDBWKXMG, AR24HPSDBWKXMG, AR24HCSDBWKNMG, AR18HPSDBWKNMG, and AR18HCSDBWKNMG, is no exception. These models combine innovative technology with user-friendly features to provide efficient cooling and heating options for any space.

One of the standout features of these models is Samsung's Digital Inverter technology. This technology allows the air conditioners to adjust their compressor speed to maintain the desired temperature more efficiently. By reducing energy consumption, the Digital Inverter technology not only helps in lowering utility bills but also minimizes noise levels, providing a more comfortable environment.

Another important aspect is the Smart Installation feature, which simplifies the setup process. Once the unit is installed, the system runs a diagnostic check to ensure everything is functioning correctly. This feature helps users avoid potential issues and provides peace of mind regarding their investment in a Samsung air conditioner.

The AR series also comes with Samsung's unique Wind-Free cooling technology. This innovation ensures that cool air is distributed uniformly throughout the room without the discomfort of cold drafts. The air flows through micro holes in the front panel, providing a gentle and consistent cooling experience.

Energy efficiency is a top priority for modern consumers, and these Samsung air conditioners are designed with eco-friendly R32 refrigerant. This refrigerant has a lower Global Warming Potential (GWP) compared to traditional refrigerants, making it a more sustainable choice for the environment.

In terms of design, these models boast a sleek and modern aesthetic that fits seamlessly into any interior decor. The easy-to-clean filters and anti-bacterial coating ensure that the air quality in your home is not compromised, providing a healthy living environment for you and your family.

Moreover, user convenience is enhanced with the presence of smart controls via Samsung's SmartThings app. Users can easily monitor and control their air conditioners from their smartphones, allowing for precise temperature management and efficiency even when away from home.

In conclusion, the Samsung AR18HCSDBWKXMG, AR24HPSDBWKXMG, AR24HCSDBWKNMG, AR18HPSDBWKNMG, and AR18HCSDBWKNMG air conditioners are designed with cutting-edge technology, energy efficiency, and user-friendly features in mind. These models not only enhance home comfort but also promote sustainability, making them an excellent choice for modern households looking to balance performance with environmental responsibility.
