LG LMU360HHV 36,000 BTU Configurable Five-Zone Multi F Mini-Split Air Conditioner Heat Pump - Energy Star
Year-round comfort with LG's NEW Multi-F Systems equipped with LGRED° Heat Technology for low temperature heating down to -13°F!
Year round comfort control is here. With the new LG LMU360HHV Multi-F mini split system, you can provide the right temperature and customize the look in up to five rooms. It is a 48,000 BTU configurable five-zone mini split air conditioning and heating system. LG's Flex Multi-Split Five-Zone air conditioner system gives you the opportunity to install as few as two or up to five independently operated, indoor units virtually anywhere in your home. This system is Energy Star Qualified when used with non-ducted or ducted units only. It is not Energy Star when used with mixed ducted and non-ducted units.
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 temperatures are as low as 5°F it will perform at 100% heating capacity! The system will also provide low ambient cooling with temperatures as low as 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.
This system combines individual room temperature control with low operating costs. The LMU360HHV can be easily installed without major renovations. Small line sets (sold separately), which only require about a 3” hole, are run from the outdoor unit to each indoor unit.
The LMU360HHV outdoor unit offers standard features including a super 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 147.6’ of line.
This system does require some additional installation items as pictured in the illustration above. In addition to the outdoor unit (LMU360HHV), a Y connector/branch, and up to 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. Each unit installed can be easily matched to your room requirements both in terms of decor and BTUs. 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 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.
Because of the complexity and flexibility of configuring the LG LMU360HHV and all the required components, we ask that you contact us for expert advice and purchasing.
LG offers ultimate flexibility and configurability in your selection of indoor unit. All indoor units offer a variety of fan speed options and auto restart operation. Need help deciding? Contact us for expert advice in putting together your custom system.
Indoor Unit Options
Standard Wall Unit (LMN079HVT, LSN090HSV5, LSN120HSV5, LMN159HVT, LSN180HSV5 and 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 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 (LMHN240HV) - 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 as well as wired thermostat for control.
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 (VAHU) (LMVN240HV, LVN180HV4, LVN240HV4) - LG currently offers two types of vertical air handlers. There is a 2-way air handler (LMVN240HV) that can be used for upflow and downflow installations only. Also available are 4-way, multi-position air handlers (LVN180HV4 and LVN240HV4). 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. 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.
