Get year-round comfort in all areas of your home!

With LG's new Multi F Max Mini Split Air Conditioner and Heat Pump System, flexibility is the name of the game, so to speak. The LG LMU480HV outdoor compressor is compatible with many LG indoor unit styles and capacities. With the ability to connect and operate up to 8 interior units, either independently or all at once, you get all of the advantages of central air, typically without any duct work. However, units such as the vertical air handler (must be ducted) or the concealed ceiling units (can be ducted) give you the ability to cool more areas with a single unit. When the LMU480HV is installed with non-ducted indoor units only, it is Energy Star Rated. This innovative system is perfect for offices, retail establishments, new homes, additions, or retrofitting older homes.

The LMU480HV has a rated cooling capacity of 48,000 BTUs. It can be connected to almost any combination of indoor units up to 8. The maximum connected capacity is 65,000 BTUs. The unit must be connected to a minimum of 2 units with a combined minimum BTU rating of 21,000 BTUs.

The Multi F Max units also feature expanded heating capabilities for outside temperatures down to -4°F and up to 64°F. For most of the United States, a system such as the LMU480HV can be used as the primary heat supply for your space. Additionally, in the cooling mode, the capabilities range from 14°F - 118°F.

As you can see in the illustration, this system does require some additional installation items. This installation, as shown, would require one outdoor unit (LMU480HV), a Y connector/branch, two Branch Distribution Boxes and the indoor units. The indoor units shown include two ceiling cassettes, two concealed ceiling low static units, two standard wall units, and two mirrored art cool units. Although neither the Art Cool Gallery Unit, high static concealed ceiling unit, nor the Vertical Air Handler Unit are pictured, they are compatible. Each indoor unit has its own temperature control, allowing each room to be individually controlled at different temperatures.

LG 8 Zone System

The Y Branch splits the initial line, each line connects to a Branch Distribution Box and then each indoor unit is connected via its own line to a Branch Box. Line sets and communication wire (sold separately) connect to each indoor unit.

Four branch distribution boxes are available to customize your installation. Each branch distribution unit is specific to the number of indoor units you will be using. There is a 2 unit (PMBD3620), offering two 24,000 BTU ports for a maximum of 48,000 BTU capacity. The 3 unit (PMBD3630), offers three 24,000 BTU ports for a maximum of 72,000 BTU capacity. And there are two options of 4 port units. The PMBD3640 offers four 24,000 BTU ports for a maximum of 73,000 BTU capacity and the PMBD3641 offers four ports including three standard ports and one 36,000 BTU port for a maximum of 73,000 BTU capacity. Depending on how many indoor units you will be installing, the correct size distribution unit needs to be installed. However, you do not need to use all the ports available at the time of your initial installation. If you think you will be adding additional indoor units in the future, you can "cap off" the unused ports on the branch distribution units until that later time.

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. These units have built-in WiFi! Available in 9,000, 12,000, and 18,000 BTUs.

Art Cool Gallery

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 Low Static Unit

Ceiling Concealed Low Static Unit (LDN097HV4, LDN127HV4, LMDN186HV)- 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 as well as wired thermostat for control. Available in 9,000, 12,000, and 18,000 BTUs.

Ceiling Concealed High Static Unit

Ceiling Concealed High Static Unit (LMHN240HV, LMHN360HV) - High Static Concealed Ceiling units are installed in a ceiling and hidden from view. They require ducting as well as registers to allow the conditioned air to come into the space. Depending on the space you are trying to condition, a this unit allows for longer duct runs from the unit itself. This way, you can install the unit and duct off into several individual areas, wherever the air is needed. This may be one large space or multiple rooms. The 24,000 BTU unit will provide comfort control up to about 1100 sq. ft. A drain pump is included with this unit as well as wired thermostat for control. Available in 24,000 and 36,000 BTUs.

Ceiling Cassette Unit

Ceiling Cassette Unit (LMCN077HV, LCN097HV4, LCN127HV4, and LMCN185HV) - 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 control. Available in 7,000, 9,000, 12,000, and 18,000 BTUs.

Vertical Air Handler Unit

Vertical Air Handler Unit (VAHU) (LMVN240HV, LMVN360HV, LVN180HV4, LVN240HV4, LVN360HV4) - LG currently offers two types of vertical air handlers. The 2-way air handlers (LMVN240HV, LMVN360HV) that can be used for upflow and downflow installations only. Also available are 4-way, multi-position air handlers (LVN180HV4, LVN240HV4 and LVN360HV4). A multi-position air handler can be installed as an upflow, downflow, horizontal left or horizontal right installation. This allows for attic or basement installations. A vertical air handler may be used as a way of replacing a conventional air handler currently being used as part of a central system. Another possibility may be that you are looking to zone your dwelling with a mini split system regardless of whether you are using existing ductwork or adding new. The 18,000 BTU multi-position unit will add comfort control to a space that is about 800 sq. ft. Either of the 24,000 BTU units can be ducted units into several rooms totaling about 1100 sq ft. With 36,000 BTUs, you can control about 1600 sq. ft. of space. All units will heat and cool your space both appropriately and efficiently. Regardless of the number of spaces you are cooling/heating, an included wall mounted thermostat will control that zone.


Line Sets

Example of Line Set without wire

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. On a system such as the LMU480HV, every indoor unit is connected to the outdoor unit through a branch distribution box. The branch distribution box is then connected to the outdoor unit through a "y" connector, as shown in the sample installation. Each indoor unit uses its own line set. Distribution boxes require line sets as well. 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.


LG Multi Zone LayoutThe LMU480HV can be used with 2-8 indoor units. Above is an example of a 4 zone layout.
