Cooling

Take advantage of our smart solutions for residential & commercial air conditioning applications.

LG HVAC systems offer a range of solutions that are cost-efficient, quiet, and attractive.They provide a smart alternative to both central HVAC and window-mounted air conditioners,and are available in a variety of configurations to suit different cooling and heating situations.

Split Systems

These innovative systems are “split”into indoor and outdoor units. The interior units are available in several different configurations: Art Cool, standard wall-mounted, floor standing and ceiling cassettes. All interior units have remote controls for easy use. Installation by a qualified HVAC contractor is safe and easy—no duct work or sheet metal is needed. Single, dual and tri-zone systems,as well as cooling only and heat pump models are available.

Through-The-Wall Models

LG’s Through-The-Wall models offer versatile, energy efficient solutions for residential and light commercial applications. Both cooling and heat/cool models are available in a variety of capacities, with most models ENERGY STAR

qualified.The standard size

chassis fits into any competitive sleeve, making upgrades a breeze.

PTAC Models

LG’s new PTAC units are perfect for lodging and healthcare applications.These units have an extremely low decibel level and outstanding sound prevention rating. Plus, LG models have efficiency ratings up to 12.7 EER, which translates into excellent energy savings.

Feature Advantages:

Look for these key features throughout the LG line.

• Attractive, customizable indoor units. Art Cool provides

numerous options to compliment any décor. The Art Cool Customizable Art Panel works like a picture frame – any art or photograph can be displayed. Other Art Cool units come in a variety of beautiful colors and finishes to suit any room.

• Multi Power System.

™

Energy-saving twin compressors: one provides power at 60% capacity until the system reaches a desired

temperature.Then the smaller compressor takes over to provide sustained operation at 40% capacity.

• R-410A Refrigerant. Environmentally friendly

refrigerant utilized in the majority of LG systems.

• Patented Plasma Air Purifying System. The 4-stage system

features a large, permanent filter and an electronic air purifier that captures microscopic contaminants like dust, mite, pollen, and pet fur.

• Triple-Filter Air Purifying System. An electrostatic filter removes

dust, pollen and smoke; an anti-fungal filter prevents bacteria and mold from forming; and a deodorizing filter freshens the air.

• Art Cool Self-Cleaning Indoor Coil. Drives dirt and moisture

from coil surface leaving it clean and fresh smelling.

• Dehumidifying Mode. Indoor unit accurately senses room

temperature and controls humidity by shutting down the compressor before a room is over-cooled.

• Chaos Swing. Electronically controlled louvers and fan speeds

create a more natural, random flow of air, reducing temperature stratification.

• Art Cool Three-way Cooling. Air flows out of the unit from

three directions, creating more natural circulation.

• Jet Cool. Operates at high speed for up to 30 minutes to quickly

cool a room down to 65° F.

• Swirl Wind. Four-way controlled louvers and fan speeds create

a stronger, wider air flow and reduce temperature stratification.

• Auto Operation. Provides three levels of comfort from which to

choose.Temperature and fan speed will set automatically.

• Manual Power Switch. Easily accessed button that allows for

continued operation if the remote control is misplaced.

• Defrost Control. Shuts down the indoor fan to prevent cold air

from being blown into the house. Removes frost from outdoor coil when the outdoor temperature is low (Heat Pump only).

• Temperature Display. Shows room temperature of interior unit.

• Auto Sleep Mode. Automatically increases the temperature

setting 2° F twice (after 1/2 hour and one hour). The interior unit shuts off when the timer setting is reached.

• Auto Restart. Automatically restarts a unit to programmed

setting when the electricity comes on after a power failure.

The LG HVAC Advantage

NOTE:All features are not available on all models. See product pages for details.

NOTE: R-410A service port access will require a special adapter to attach standard 1/4” hoses. Ask your equipment supplier for more details.

***Each system is pre-charged with enough refrigerant to charge 25 ft.of line and the interior unit.

NOTE: Systems having the outdoor unit mounted above the indoor unit (e.g. basement installations) have the following additional requirement: For systems with maximum elevation of 25 ft. (see chart above and Figure A),refrigerant lines must be oil trapped between 8 ft. and 16.4 ft. of elevation. For systems with elevation of greater than 25 ft. (see chart above), refrigerant lines must be oil trapped at least every 16.4 ft. of elevation.

Figure A. Example: 25 ft. maximum elevation.
