LG's NEW Multi-F Systems are equipped with LGRED° Heat Technology featuring low temperature heating down to -13°F!
LG's new line of multi-zone systems is here! With lower operating temperatures, these new Flex Multi Systems can provide year round comfort virtually anywhere in the US.
The Multi-F / Flex Systems are not only cost and energy efficient, they are also able to offer comfort year round with enhanced cooling and heating ranges. Featuring LGRED° Heat Technology, this system can be used as a primary heat source in most of the country. It can be operated in the heating mode when temperatures get down as low as -13°F. When the temperatures are as low as 5°G, this system will perform at 100% heating capacity! The system will also provide low ambient cooling to 14°F. Add a Low Ambient Kit (sold separately) for cooling operation down to -4°F. The new LGRED° Heat Technology Systems also include a factory installed Base Pan Heater to ensure better heat performance in colder weather.
The LG LMU180HHV is an 18,000 BTU configurable dual-zone mini split air conditioning and heating system. LG's Flex Multi-Split Dual Zone air conditioner system gives you the opportunity to install two indoor units in separate areas of your home. With a combined connectivity BTU rating of up to 24,000 the LMU180HHV can be configured to include a combination of wall mounted and ceiling units. When connected with non-ducted units only, the system is Energy Star Qualification.
Each unit operates with its own remote or thermostat (depending on the units you choose), so there is no need to condition the room you are not using. The LMU180HHV can be easily installed without major renovations. Individual line sets are required for each indoor unit (sold separately), and only require about a small 3” hole for each unit. The line sets run from each indoor unit to the outdoor unit.
Standard features of the LMU180HHV outdoor unit include an energy efficient variable speed inverter compressor, defrost/deicing capabilities, three minute restart delay, and a self diagnosis system. It also includes soft start which reduces power surges on the electrical system. It operates when the outside temperature is as low as 14°F in the cooling mode (down to -4°F with a low ambient kit installed) and from -13°F to 75°F in the heating mode. To top it all off, it uses environmentally friendly R-410A refrigerant and is precharged for up to 49.2’ of line.
LG offers ultimate flexibility and configurability in your selection of the two indoor units required for this system. All indoor units offer a variety of fan speed options and auto restart operation. You can use the dropdown boxes above to customize your system. Need help deciding? Contact us for expert advice.
Indoor Unit Options
Standard Wall Unit (LMN079HVT, LSN090HSV5, LSN120HSV5, LMN159HVT) - The standard wall unit comes in a white finish and will blend quietly and seamlessly into any room decor. It is installed high on a wall. It connects to the outdoor compressor through a small opening in your wall, drilled behind the unit. The line set and wire (required, sold separately) are sent through the opening and connect to the compressor outside. A wireless remote is included for convenient operation from anywhere in the room. These units have built-in WiFi! Available in 7,000, 9,000, 12,000, and 15,000 BTUs for use with the LMU180HHV.
Art Cool Wall Unit (LAN090HSV5, LAN120HSV5) - The Art Cool wall unit comes in a reflective, smoky black, mirrored finish that will add a modern flare to any decor, while still blending quietly into any room. Like the standard wall unit, it is installed high on a wall and connects to the outdoor compressor through a small opening drilled in your wall, behind the unit. The line set and wire (required, sold separately) connect to the compressor outside through this opening. A wireless remote is included for convenient operation anywhere in the room. Available in 9,000, and 12,000 BTUs for the LMU180HHV.
Art Cool Gallery (LMAN097HVP, LMAN127HVP) - An Art Cool Gallery unit can be a beautiful, non-obtrusive way to get conditioned air into any room of your choice. A 2’ x 2’ frame allows you to display a personal piece of artwork (or the included piece). The air is dispersed quietly and efficiently from the edges and bottom of the frame into your room. It is installed on a wall and connects to the outdoor compressor through a small opening drilled in your wall, behind the unit. The line set and wire (required, sold separately) connect to the compressor outside through this opening. A wireless remote is included for easy control. Available in 9,000 or 12,000 BTUs.
Ceiling Concealed Ducted Low Static Unit (LDN097HV4, LDN127HV4)- Low Static Concealed Ceiling units are installed in a ceiling and hidden from view. They require ducting as well as registers. The registers allow the conditioned air to come down into the space. Depending on the size and shape of your space, a concealed unit can be ducted for multiple rooms or one single room. As an example, an 18000 BTU unit will provide comfort control up to about 825 sq. ft. A drain pump is included with this unit. A controller is required to operate each indoor unit. One is not included with the unit. Available controllers include a wired simple controller PREMTC00U, or a wired, touchscreen controller PREMTA000 (each sold separately). Wire required to connect the Indoor unit to the wired controller is not included (PZCWRC1 - sold separately). Available in 9,000, and 12,000 BTUs for the LMU180HHV.
Ceiling Cassette Unit (LMCN078HV, LCN098HV4, LCN128HV4) - A ceiling cassette installs into the ceiling and offers 4-way airflow into your space. A grille is required on a ceiling unit (standard white grille included) and air is dispersed from all 4 sides of the grille. A ceiling cassette can be installed in the center of a room, allowing airflow all around. Alternatively, it can be installed along the edge of a room, closing off 1 or more "vents" for customized air flow. A drain pump is included with this unit as well as a wireless remote controller. Available in 7,000, 9,000, and 12,000 BTUs for the LMU180HHV.
Low Wall Console (LQN090HV4, LQN120HV4, and LMQN150HV) - A low wall console unit unit can be installed as a flush or recessed mounted wall/floor standing unit. The air is dispersed quietly and efficiently from the bottom of the unit and into your room. It is installed low on a wall and connects to the outdoor compressor through a small opening drilled in your wall, behind the unit. The line set and wire (required, sold separately) connect to the compressor outside through this opening. A wireless remote is included for easy control. Available in 9,000, 12,000 and 15,000 BTUs.
Mini Split Line Sets - Line sets are a requirement when installing a mini split system. They are the connection between the outdoor unit and the indoor units of your system. Every indoor unit needs to be connected directly to the outdoor unit with its own line set. Most Mini Split Line Sets come with flared connectors attached and are ready to install. Our line sets are offered with and without control wire and are available in various connection sizes and lengths to meet your installation needs. The line set shown in the photo does not include the control wire.
