Step 4.3 Performing final check and trial operation

1Check the following:

•Strength of the installation site

•Tightness of pipe connection to detect gas leak

•Electric wiring connection

•Heat-resistant insulation of the pipe

•Drainage

•Grounding conductor connection

•Correct operation (Take the following steps.)

2Press the (Power) button on the remote control to check the following:

•The indicator on the indoor unit lights up.

•The airflow blade opens and the fan gears up for operation.

3Press the (Mode) button to select Cool or Heat mode. Then take the following sub-steps:

•In Cool mode, use the Temperature button to set the set temperature to 16 °C.

•In Heat mode, use the Temperature button to set the set temperature to 30 °C.

•Check whether, approximately 3 to 5 minutes later, the outdoor unit starts, and a cool or warm air blows out.

•After12 minutes of stationary condition, check the indoor unit air treatment.

4Press the (Air swing) button to check whether the airflow blades work properly.

5Press the (Power) button to stop the trial operation.

Pumping down refrigerant

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.

1Shut off the liquid valve with the Allen wrench.

2Turn on the air conditioner in cooling with fan operating at high velocity. (Compressor will immediately start, provided 3 minutes have elapsed since the last stop.)

3After 2 minutes of operation, shut the suction valve with the same wrench.

4Turn off the air conditioner and switch mains supply off.

5Disconnect tubing. After disconnection, protect valves and tubing ends from dust.

CAUTION

•Compressor damage may occur if the compressor is run at a negative suction pressure.

Pumping down for removing the product

1Turn on th air conditioner and select Fast Cool mode.

2Let the compressor run for more than 5 minutes. If the compressor does not operate for more than 5 minutes due to protection control, wait about 2 minutes, and then carry out the next procedure.

3Release the valve caps on High and Low pressure side.

4Use L-wrench to close the valve on the high pressure side.

5After approximately 1 minute, close the valve on the low pressure side.

6Stop operation of the air conditioner by pressing the (Power) button on the indoor unit or remote control.

7Disconnect the pipes.

AR24MRFHRWKNMG, AR24MQFHRWK/MG, AR24KQFHRWKNMG, AR18MRFHCWKNMG, AR18MQFHCWKNMG specifications

The Samsung AR24MRFHRWK/MG, AR24MRFHRWKXMG, AR24KRFHRWKNMG, AR24MQFHRWKNMG, and AR24KRFHRWK/MG are part of Samsung's innovative line of air conditioning units designed to deliver optimal cooling and heating performance. These models cater to diverse consumer needs, featuring advanced technology, energy efficiency, and user-friendly designs.

One of the standout features of these air conditioning units is the Digital Inverter Technology. This technology allows the compressor to operate at variable speeds, significantly reducing energy consumption while maintaining a consistent temperature. Unlike traditional air conditioners that frequently turn on and off, the inverter compressors adjust their speed according to the cooling demand. This not only saves energy but also enhances the lifespan of the unit.

These models also emphasize air quality through a multi-stage filtration system. The filters effectively capture dust, allergens, and other particles, ensuring that the air circulated within the room is clean and healthy. The long-lasting filters are designed for ease of maintenance, allowing users to replace or clean them with minimal effort.

Moreover, the cooling efficiency is backed by a range of features aimed at enhancing comfort. The models come with a fast cooling mode that allows users to achieve desired temperatures quickly, ideal for those hot summer days. Additionally, the units are equipped with a Quiet Mode, ensuring minimal noise levels, making them suitable for use in bedrooms or workplaces.

Energy efficiency is a key characteristic of the Samsung AR24 series. With a high Energy Efficiency Ratio (EER) and seasonal energy efficiency ratings, these models not only lower energy bills but also contribute to a reduced environmental impact.

Smart technology integration is another compelling aspect of these units. Users can control their air conditioning systems remotely via smartphone applications, allowing for temperature adjustments and scheduling from anywhere. This feature enhances convenience and ensures that spaces are pre-cooled or heated before arriving home.

Further enhancing user experience, the sleek design of these models ensures they fit seamlessly into modern interiors. Their compact and stylish appearance makes them a visually appealing addition to any space, whether residential or commercial.

In summary, the Samsung AR24 series showcases advanced air conditioning technology combined with energy efficiency, ease of use, and superior air quality features, establishing it as an excellent choice for consumers looking for reliable and stylish climate control solutions.
