LG's NEW Multi-F Systems now include LGRED° Heat Technology featuring low temperature heating down to -13°F!
LG's new line of energy efficient multi-zone systems is here. The entire line features LGRED° Heat Technology, making each unit a perfect solution for cold weather climates. The LG LMU300HHV can be operated in the heating mode when temperatures get down as low as -13°F and it 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 LG LMU300HHV is a 30,000 BTU, configurable, multi-zone mini split air conditioning and heating system. Flexibility is part of the name with LG's Flex Multi-F Quad Zone Multi-Split air conditioner. The LMU300HHV gives you the flexibility of choosing two, three or four indoor units. Mix and match units to fit your room size and decor. This four-port system offers a combined BTU connectivity rating of up to 40,000 BTUs. With a focus on energy efficiency, this mini split system offers a high SEER rating and is Energy Star Qualified when used with non-ducted indoor units such as wall units and ceiling cassettes.
The improved heating range on this system allows for operation in the heat mode when outdoor temperatures are as low as -13°F. With heating possible when it is that cold, this unit is a feasible option as a primary heat source for much of the country. And, if you need to keep an area cool even when it is cold outside, this system will operate in the cooling mode with temperatures as low as 14°F.
Each unit comes with its own remote or thermostat giving you the utmost in comfort flexibility. Each space can be adjusted individually or completely off. Another advantage of adding a mini-split system like the LMU300HHV is the ease of installation. No ductwork is needed and, while each indoor unit requires a line set and wire (sold separately), only a small 3” hole is required to connect each indoor unit to the outdoor unit.
In addition to being an energy efficient way to heat and cool your home, the LMU300HHV outdoor unit offers many other standard features including a variable speed inverter compressor, defrost/deicing capabilities, three minute restart delay, and a self diagnosis system. The LG Multi-F compressor uses a soft start in an effort to reduce power surges on the electrical system. The outdoor unit will operate in the cooling mode when the outside temperature is as low as 14°F. In the heating mode perform with temperatures ranging from -13°F to 75°F. To top it all off, it uses environmentally friendly R-410A refrigerant and is pre-charged for up to 98 feet of line.

THIS IS THE INDOOR UNIT ONLY. PLEASE SEE BELOW FOR THE FULL SYSTEM (INCLUDING THE INDOOR AND OUTDOOR UNITS). IT IS ALSO COMPATIBLE WITH THE MULTI-ZONE SYSTEMS
The Standard Wall Unit is available in several different sizes: LMN078HVT 7,000 BTUs, LSN090HSV4 9,000 BTUs, LSN120HSV4 12,000 BTUs, LMN157HVT 15,000 BTUs, LSN180HSV4 18,000 BTUs, and LMN247HVT 24,000 BTUs.This wall unit features 12000 BTUs and can be used in a single zone application with the LG LSU120HSV4 outdoor unit or as part of a multi zone system. LG's flex, multi-split systems operate 2 to up to 8 interior units. Each indoor unit is mounted in a separate room and is operated totally independently from one another. All indoor units are connected to a single exterior unit.
Features of the Standard Wall unit include:
- Chaos Swing: Electronically controlled louvers and fan speeds create a more natural, random air flow thereby reducing temperature stratification.
- Jet Cool/Jet Heat: Operates at high speed for up to 30 minutes to quickly cool a room down to 64°F
- Self-Cleaning Indoor Coil: Drives dirt and moisture from coil surface leaving it clean and fresh smelling.
- Auto Operation (Artificial Intelligence): Provides three levels of comfort from which to choose. Temperature and fan speed will set automatically.
- Auto Restart Operation: Automatically restarts a unit to programmed setting when the electricity comes on after a power failure.

LG's LSN180HSV4 18,000 BTU indoor wall unit can be used with either the LSU180HSV4 single zone or multi zone (3 unit or more) outdoor units. SEER and EER are dependent on your system setup. The technical specs shown for this indoor unit reflect use in a multi-zone system. One of the main differences is the line set size used. When the LSN180HSV4 is used in a multi-zone application, it uses 1/4" x 1/2" line set. When used in a single zone application, it uses 3/8" x 5/8" line set.The LG split systems include an inverter heat pump. Air conditioners with inverter technology use a variable speed compressor which continues to operate at a low speed to maintain the temperature. Conventional Air Conditioners use a constant speed compressor that completely shuts off once the temperature is achieved. A mini split is also quieter to operate and uses less energy than conventional air conditioners
