About LG Electronics, Inc.
LG Electronics is a global leader and technology innovator in con-
sumer electronics, mobile communications, and home appliances.
LG Electronics comprises five business units—Home Entertainment,
Mobile Communications, Air Conditioning, Business Solutions, and
Home Appliance. LG is one of the world’s leading producers of flat
panel televisions, audio and video products, mobile handsets, air
conditioners, and washing machines. LG’s commercial air condition-
ing business unit was established in 1968 and has built its lineup of
residential and commercial products to include VRF, Multi F, duct-
free split systems, packaged terminal air conditioners (PTACs), and
room air conditioners. In 2011, the air conditioning and energy solu-
tions business unit grew to include LED lighting and solar products.

Multi-Zone Systems
LG HVAC systems offer a range of solutions that are cost efficient,
quiet and attractive. Multi-zone systems are “split” into indoor and
outdoor units, and provide a smart alternative to both central HVAC
and window-mounted air conditioners. These inverter heat pump sys-
tems are available in a variety of configurations to suit different cool-
ing and heating situations. Installation by a trained HVAC contractor
is safe and easy – little to no duct work or sheet metal is required.
Multi F Systems
LG’s inverter heat pumps can support two, three, or four indoor
units that are typically installed in separate rooms. Indoor units can
be used with different controllers, allowing the customer to set the
temperature individually. Indoor units are available in several different
congurations: Art Cool™ Mirror-mounted, Art Cool Gallery wall-
mounted, standard wall-mounted, low wall console, four-way ceiling
cassettes, ceiling-concealed duct (high and low static), and vertical-
horizontal air handling models. Multi F MAX systems can operate up
to eight indoor units through two-, three-, or four-port branch distribu-
tion units.
Adaptable and Flexible
Multi F outdoor units can be adapted to a wide range of building ap-
plications and sizes such as schools, hotels, hospitals, ofces, and
residences. The system components are lightweight and compact so
they can be placed in buildings without expensive cranes, they easily
fit into most service elevators, and they can be set in place with
minimal structural reinforcements requirements.
Multi F technology allows you to pipe farther by reaching areas of the
building that would require the installation of a second system when
using traditional direct-expansion cooling and heating equipment. Multi
F provides the designer with uncompromised pipe system engineering
exibility—long pipe runs and large elevation differences. Whether your
building is a condominium, a hotel, a school, or an ofce complex, Multi
F is best suited to reach the farthest corners and elevations.
Smaller Chases and Plenums
LG Multi F systems use refrigerant piping to move heat, resulting in
smaller space requirements for piping as compared to chilled water
or roof top systems. This helps reduce the overall construction and
material cost of the building, and gives back leasable space. Flexible
and logical placement of system components, reduced back-and-
forth pipe lengths, and fewer joints lowers installation costs and
minimizes potential leaking.
Quality Commitment
LG is committed to the success of duct-free projects. We provide
technical support during installation and commissioning. LG offers
a variety of classes designed for
installers and servicers on Multi
F installation. Classes are con-
ducted at LG’s training centers
and in field locations at various
times throughout the year and on
special request.
Benefits of Multi F Systems
• Individual zone control
• Long refrigerant piping lengths
• High refrigerant piping elevation differences
• Maximum flexibility
• Operating ranges of 14°F to 118°F (DB) in cooling and -4°F to
75°F (DB) in heating if connected to standard Multi F Outdoor Units
or -13°F to 75°F (DB) in heating if connected to Multi F with LG
REDº Outdoor Units.
