Maintenance and Service

OutdoorUnit

The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, the heat exchanger

and panel vents may be professionally steam cleaned.

CommonProblems And Solutions

Before calling for service

If you have problems with your air conditioner, read the following information and try to solve the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.

Air conditioner does not operate

1.Ensure that the air conditioner is plugged into a proper outlet.

2.Check the fuse or circuit breaker.

3.Check whether the voltage is unusually high or low.

Air does not feel cold enough on the cooling setting

1.Ensure that the temperature settings are correct.

2.Check to see if the air filter is clogged with dust. If so, replace the filter.

3.Ensure that the air flow from the outside is not obstructed and that there is a clearance of over 20" between the back of the air conditioner and the wall or fence behind it.

4.Close all doors and windows and check for any source of heat in the room.

Before calling for service, please review the following list of common problems and solutions.

The air conditioner is operating normally when:

You hear a pinging noise. This is caused by water being picked up by the fan on rainy days or in highly humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.

You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit.

You hear the fan running while the compressor is silent. This is a normal operational feature.

EN 61000-3 Norm), EN 61000-2 specifications

LG Electronics is committed to delivering cutting-edge technology while ensuring compliance with international standards. Among these standards are the EN 61000-2 and EN 61000-3 norms, which address electromagnetic compatibility (EMC) and are critical in defining how electrical and electronic devices interact with their electromagnetic environment.

EN 61000-2 focuses on the environment within which devices operate. This standard outlines the general requirements for the compatibility of various electrical devices in residential, commercial, and industrial environments. It specifies the necessary electromagnetic interference (EMI) levels to protect devices from disturbances that could impact their functionality. For LG Electronics, adherence to EN 61000-2 means engineering products that minimize the potential for EMI disruptions, thereby ensuring reliable performance in diverse settings.

On the other hand, EN 61000-3 addresses the emission limits for harmonic currents in electrical systems and equipment. It focuses on ensuring that devices do not generate excessive current harmonics that could disrupt the normal operation of other equipment. For LG, compliance with EN 61000-3 involves implementing technologies that reduce harmonic distortion, which improves the overall power quality in electrical systems. This aspect is particularly important for ensuring energy efficiency and enhancing the longevity of both LG products and the systems they are integrated into.

One of the main features of LG’s products that adhere to these standards is the incorporation of advanced filtering technologies. These filters are designed to suppress harmful electromagnetic emissions and ensure that devices operate within permissible limits. Furthermore, LG employs superior circuit designs that prioritize efficient power management, helping to minimize harmonic generation.

Moreover, LG’s commitment to sustainability is reflected in its adherence to these norms. By reducing electromagnetic emissions and improving power quality, LG Electronics not only complies with regulations but also contributes to a greener environment. This aligns with the company’s broader vision of producing environmentally friendly and energy-efficient products.

In summary, LG Electronics continuously invests in technologies that ensure compliance with EN 61000-2 and EN 61000-3 norms. Through advanced filtering solutions and efficient circuit designs, the company demonstrates its dedication to electromagnetic compatibility, reliability, and sustainability, reinforcing its position as a leader in the global electronics market.
