Maintenance and Service

TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.

AirFilterCleaning

The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the filter will build up and block the airflow. This reduces the cooling capacity and also causes an accumulation of frost on the cooling coils.

If the filter becomes turn or damaged you should replace immediately. Replacement filters are available from your salesperson, dealer, and the authorized customer service centers.

1. Remove the air filter from the front grille assembly by pulling the air filter up slightly.

2. Wash the filter using lukewarm water below 40° C (104° F).

3. Gently shake the excess water from the filter completely. Replace the filter.

ENGLISH

VentFilter

Before cleaning the vent filter, disconnect power to the unit by unplugging the power cord at the wall outlet or subbase, or disconnect power at the fuse box or circuit breaker. If unit is operated with vent door closed, the vent filter does not need to be cleaned.

1.Remove the cabinet front as described in Front Removal.

2.Remove the six screws securing the chassis to the wall sleeve with a Phillips-Head screwdriver.

3.Slide the chassis out of the wall sleeve far enough so that the vent filter is accessible as shown in Figure A.

4.Remove the vent filter by unscrewing the two screws at the top of the filter and gently pulling the filter away from the partition panel. Refer to Figure B.

5.Clean and replace the filter by reattaching the hook to the bottom of the vent door and replacing the two screws, slide the chassis back into the wall sleeve, secure it in place with six screws and reinstall the front cabinet.

PACKAGED TERMINAL AIR CONDITIONER/HEAT PUMP specifications

LG Electronics is a leading name in the HVAC industry, well-known for its innovative solutions such as the Packaged Terminal Air Conditioner/Heat Pump (PTAC/HP). The PTAC units from LG are designed to deliver efficient heating and cooling in a compact form, making them ideal for hotels, healthcare facilities, and residential applications.

One of the main features of LG's PTAC units is their self-contained system, which allows for easy installation and maintenance. The units are designed to fit into a standard wall sleeve, which simplifies the replacement process in existing buildings. LG offers a range of models, with cooling capacities typically ranging from 7,000 to 15,000 BTU; this ensures that users can select the perfect size for their specific requirements.

Efficiency is a hallmark of LG’s PTAC models, with many units rated with high Energy Efficiency Ratios (EER) and Seasonal Energy Efficiency Ratios (SEER). This efficiency not only results in lower energy bills but also contributes to a more sustainable operation, aligning with modern environmental standards. Some advanced models feature inverter technology, which allows for variable speed control of the compressor, significantly reducing energy consumption while providing optimal comfort levels.

The PTAC units come equipped with a multi-functional remote control, allowing for convenient operation without the need to manually adjust settings. This user-friendly feature helps to improve the overall comfort experience for guests or residents. Additionally, LG’s units often include a gold fin coating on the coils to resist corrosion, ensuring longevity and reliability even in harsh environments.

A notable characteristic of LG’s PTAC/HP units is their silent operation. Designed to minimize noise disruption, these units are perfect for settings where peace and quiet are paramount, such as hotels and bedrooms. Furthermore, many models feature a "sleep mode" function, which subtly adjusts the temperature while minimizing noise during nighttime hours.

LG also prioritizes indoor air quality, integrating advanced filtration systems that help capture dust and allergens, promoting a healthier indoor environment. The units are designed to provide consistent airflow, ensuring even temperature distribution and enhancing overall comfort.

In conclusion, LG Electronics Packaged Terminal Air Conditioner/Heat Pump units represent a perfect blend of efficiency, comfort, and convenience, making them a top choice for various applications. Their self-contained design, energy-saving technologies, and user-friendly features ensure that they are suitable for a wide range of indoor climates, meeting the modern demands of energy-conscious consumers.
