Maintenance and Service

Whentheair conditioner is not going tobeused for along time.

When air conditioner is not going to be used for a long time.

1.Operate the air conditioner on Air circulation mode (Refer to page 21) for 2 to 3 hours.

• This will dry out the internal mechanisms.

2.Turn off the circuit breaker, and disconnect the power cable.

CAUTION: Turn off the circuit breaker when the air conditioner is not going to be used for a long time.

Dirt may collect and may cause a fire.

3.Remove the batteries from the Remote Controller.

When the air conditioner is to be used again.

1.Clean the air filter and install it in the indoor unit.

(Refer to page 23~25for cleaning filters.)

2.Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.

OperationTips

Do not overcool the room.

Keep blinds or curtains

closed.

uniform.

This is not good for the health and wastes electricity.

Do not let direct sunshine enter the room when the air conditioner is in operation.

Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.

Make sure that the doors and windows are shut tight.

Avoid opening doors and windows if possible to keep the cool air in the room.

Clean the air filter regularly.

Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

Ventilate the room occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

EN 61000-3, EN 61000-3 NORM specifications

LG Electronics has consistently been at the forefront of technological innovation, and its commitment to compliance with international standards is evident in its adherence to EN 61000-3 norms. The EN 61000-3 series focuses on electromagnetic compatibility (EMC) concerning emissions and immunity, particularly in residential, commercial, and light-industrial environments. This standard is critical for ensuring that electronic devices do not generate excessive electromagnetic interference (EMI), while also ensuring their proper functioning in the presence of such interference from other devices.

One of the main features of the EN 61000-3 standard is the regulation of harmonic emissions. Devices must limit the levels of harmonic currents they introduce into the power system. This requirement is crucial for maintaining the integrity of electrical networks and preventing issues that could arise from harmonics such as overheating and equipment failures. LG Electronics ensures that its products, including appliances and electronic devices, are designed to stay within the specified limits of the norm, thereby promoting energy efficiency and longevity.

Another characteristic of the EN 61000-3 standard is its focus on voltage fluctuations and flicker. Voltage fluctuations can lead to flickering lights and other undesirable effects. By adhering to these requirements, LG Electronics demonstrates its dedication to providing products that enhance user experience and reduce discomfort. This is especially critical in environments where stable power supply is essential, such as in home theaters or professional audio setups.

In terms of technologies, LG incorporates advanced filtering techniques and power management systems in its devices to ensure compliance with the EN 61000-3 norms. These technologies help mitigate EMI and ensure that the devices operate effectively in varied electrical environments. Furthermore, LG's commitment to research and development allows the company to innovate continuously, ensuring that its future products will not only comply with current standards but also embrace ongoing changes in global regulations.

In conclusion, LG Electronics' adherence to the EN 61000-3 norms underscores its commitment to producing high-quality, reliable, and efficient electronic devices. By prioritizing harmonics control and mitigating voltage fluctuations, LG not only enhances user experience but also contributes to a sustainable future. Through ongoing technological advancements and compliance with stringent international standards, LG reinforces its position as a leader in the electronics industry.
