Training
The LG US Air Conditioning division is headquartered near Atlanta in Alpharetta, Georgia, along with a full training
academy. Additional training academies are located in California, Texas and New Jersey. Since 2008, our academies have
trained thousands on the advantages of LG air conditioning systems, and even more have been trained through LG’s
online training modules. World class trainers with years of experience teach classes in ductless technology, with topics
covering everything from installation to service for the full range of LG air conditioning products. LG also has several
strategically placed partner academies throughout the United States that offer a number of LG training classes as well.
For HVAC professionals, LG offers online instruction via our Learning Management System and classroom training at our
training academies, strategically placed throughout the country. Training is open to all contractors; ask your LG Electronics
authorized distributor for details. For more information and to nd out how you can be part of the next training class near
you, visit lg.learnernation.com.
Service Tools
As part of our commitment to innovation, LG has developed innovative ways to enhance the service technician’s experience
during routine maintenance or service with these tools:
• LG Monitoring View (LGMV) Software and Mobile App both connect to LG Multi V Systems to allow technicians
to troubleshoot accurately and evaluate equipment performance by interfacing directly with the unit. The software
provides an accurate picture of an operating system without the need to check system temperatures manually, access
the refrigerant circuit for system pressures, or perform time-consuming resistance and voltage tests. This service tool
provides the most effective troubleshooting method for LG Multi V equipment.
• LG Telepresence connects technicians in the eld directly to LG Technical Assistance representatives via a live video
feed through the technician’s smartphone, allowing you to bring LG technical support with you to any jobsite.

LG Air Conditioning Technologies
Performance
Expansive operating range in cooling and heating without
adding accessories
• LG Multi V 5 uses vapor injection technology for
improved heating performance in ambient conditions
as low as -13˚F.
• Using a variable path heat exchanger, LG Multi V 5
performs in low ambient conditions to provide cooling
down to 5˚F.
Design Flexibility
• Higher-Elevation Piping Technology
More floors with fewer systems. LG Multi V 5
eliminates the need to invest in extra systems
and saves on installation. Enjoy no heating
capacity losses due to long pipe length.
• Compact & Lightweight
More indoor zones, less outdoor space. When
space or access is at a premium, Multi V 5 offers
significant cost advantages on large projects.
Efficiency
Advanced features for superior efficiency
• Advanced Smart Load Control
Automatically adjusts system target pressures based
on outdoor temperature and humidity for increased
cooling performance.
• Active Refrigerant Control
Depending on the operating mode and conditions,
the system refrigerant level is automatically adjusted
for increased part load and heating efciency.
• Variable Path Heat Exchanger
Depending on the operating mode and conditions,
both the refrigerant ow path and velocity are
adjusted for improved efciency.
• Advanced PCB Cooling
Improved cooling performance of the inverter PCB
by using liquid refrigerant instead of heat sink
cooling methods.
• LG Inverter Scroll
Innovative high side-shell design creates a more compact
unit providing the same capacity output, with greater
reliability in cold climates.
• HiPOR™ (High-Pressure Oil Return)
Oil is returned to the compressor through a separate
inlet pipe, ensuring that compressor energy is used to
compress refrigerant only.
• Smart Oil Control
Eliminates timed oil-return cycles and takes hours off of
the time required to return oil compared to systems that
use a timed oil-recovery cycle.
• Intelligent Heating
By monitoring the outdoor humidity, system target
pressures can be reduced to extend heating operation,
delay defrost operation and reduce power consumption.
Comfort
• Quiet Operation
Multi V indoor units are among the quietest in the
industry, with rated sound levels as low as 23dB(A). In
addition to temperature, airflow and dehumidication,
extremely low sound levels contribute to a relaxing
environment.
• Individualized Zone Control
Multi V systems allow the user to control the space to
the exact temperature desired. This further enhances
comfort while promoting reduced power consumption.
• Indoor Air Quality
All Multi V indoor units incorporate a reusable,
washable lter. Since distribution and return ducts
are not required for this system, dust and duct mold
accumulation are reduced, contributing to improved
indoor air quality.
