The flexibility of installation options with LG's new Multi F Max Mini Split Air Conditioner and Heat Pump System is hard to compare. The LG LMU601HV outdoor compressor is compatible will all 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. Some units, such as the Vertical Air Handler (must be ducted) or the Ceiling Units (can be ducted), give you the ability to cool more than one space with a single unit. This innovative system is perfect for offices, retail establishments, new homes, additions or retrofitting older homes.
The rated cooling capacity of the LMU601HV is 60,000 BTUs with a maximum connected capacity of 81,000 BTUs. It is an excellent solution for heating and cooling several spaces at one time. Although the unit must be connected to a minimum of 2 units with a combined minimum BTU rating of 24,000 BTUs, the allowable combinations gives you the opportunity to customize every space where you need conditioned air.
The LG Multi F Max units are a great solution for colder weather climates. They 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 LMU601HV can be used as the primary heat source for your installation. 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 (LMU601HV), a Y connector/branch, two Branch Distribution Boxes and the indoor units. 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 through small 3" holes drilled behind for each unit.
LG gives you several indoor unit options to help you customize the look in every room. An example of the variety of connectable indoor units includes this six unit installation. As shown, it includes a Ceiling Cassette, an Art Cool Gallery unit, a Concealed Ceiling Low Static unit, a Standard Wall unit, a Mirrored Art Cool unit and a Vertical Air Handler. Each unit installed can be easily matched to your room requirements both in terms of decor and BTUs. Although the high static concealed ceiling unit is not pictured in the above installation, it is compatible as well. Each indoor unit has its own temperature control, allowing each room to be individually controlled at different temperatures.
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 24,000 BTU 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.
Because of the complexity and flexibility of configuring the LG LMU601HV and all the required components, we ask that you contact us for expert advice and purchasing.
Indoor Unit Options
Standard Wall Unit (LMN079HVT, LSN090HSV5, LSN120HSV5, LMN159HVT, LSN180HSV5, LMN249HVT) - 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, 15,000, 18,000, and 24,000 BTUs.
Art Cool Wall Unit (LAN090HSV5, LAN120HSV5, LAN180HSV5) - 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. These units have built-in WiFi! Available in 9,000, 12,000, and 18,000 BTUs.
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, LDN187HV4)- 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, 12,000, and 18,000 BTUs.
Ceiling Concealed Ducted High Static Unit (LHN248HV, LHN368HV) - 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 high static 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. A controller is required to operate each indoor unit as well as a wireless remote control. 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).
Ceiling Cassette Unit (LMCN078HV, LCN098HV4, LCN128HV4, and LCN188HV4) - 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 (VAHU) (LVN181HV4, LVN241HV4 and LVN361HV4) - Vertical Air Handlers are 4-way, multi-position air handlers. 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. The 24,000 BTU unit 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, a wall mounted thermostat will control that zone. 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).
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. On a system such as the LMU601HV, 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.
