Introduction
About LG Electronics
LG Electronics is a global leader and technology innovator
in consumer 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 conditioning business unit was established in 1968 and has built
its lineup of residential and commercial products to include VRF,
Flex-Multi, duct-free split systems, packaged terminal air condition-
ers (PTACs), and room air conditioners. In 2011, the air conditioning
and energy solutions business unit grew to include LED lighting and
solar products. For more information, visit www.lg.com.
Duct Free Split Systems
LG HVAC systems offer a range of solutions that are cost efficient,
quiet and attractive. Duct Free Split 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 systems are available in a variety of configurations to suit
different cooling and heating situations. Installation by a qualified
HVAC contractor is safe and easy – little to no duct work or sheet
metal is required.
Inverter Systems
LG Single Zone Inverter Wall Mount air-source systems offer the
opportunity to minimize ductwork in the same configuration. The
system offers zoning without the need for zone damper systems.
The LG Single Zone Inverter Wall Mount system’s advanced controls
provide exceptional building dehumidification and temperature
control, and can rapidly adapt system operating parameters to the
ever changing building load. The LG Single Zone Inverter Wall Mount
system is easy to design, install, and maintain. The modular design
allows occupants to control their environmental condition, providing
individualized control of the set-point temperature and allowing oc-
cupants to condition only the occupied zones.
Quality Commitment
LG is committed to the success of Duct Free Split projects. We
provide industry leading technical support during installation and
commissioning. LG offers a variety of classes designed for installers
and servicers to ensure that every system installation is completed
successfully.
Classes are conducted at LG’s training centers and in field locations
at various times throughout the year and upon special request.

•All-season use - heat pump models for both
cooling and heating capabilities
•Operating ranges for Outdoor units of 14°F to
118°F (DB) for cooling; -13°F to 65°F (WB) for
heating
•Operating ranges for Indoor Units of 53°F to
75°F (WB) for cooling; 60°F to 86°F (DB) for

Convergence of Technological Innovation with Flexibility and Style
Single Zone Inverter
Wall Mount
Choosing an LG Single Zone Wall Mount
product provides a system designer an
edge to engineer a system with indi-
vidual control, and design flexibility with
advanced controls. The Art Cool Premier
Outdoor and Indoor units are available
in a nominal capacity range of 3/4 to 1
ton. These are best suited for applica-
tions with zones that require heating or
cooling, such as residential, and small
business office buildings.
Single Zone Wall Mount Outdoor
and Indoor units are available in
208–230V/60Hz/1Ph.
Adaptable and
Flexible
The Single Zone Wall Mount System
allows cooling or heating for the entire
residence or just a single room without
the need for evasive duct work. There is
minimal renovation needed.
Long refrigerant piping lengths allow
for extra design flexibility in indoor unit
installation.
These units may be used for a number of
residential or commercial environments
such as:
•Older homes
•New home construction
•Office buildings
•Restaurants
•Hospitals / Medical facilities
•Schools
•Nursing homes
•Retail establishments
•Houses of worship
Inverter Technology
Inverter variable-speed Duct Free Split
Systems are measurably quieter and
consume less energy than conventional
air conditioners. The Inverter compressor
ramps up or down to match the required
room capacity and maintain the comfort
level. When the selected temperature
is reached, the inverter compressor
operates at low speed to maintain that
comfort level, thereby using less energy.

Art Cool Premier Wall Mounted Engineering Manual
Due to our policy of continuous product innovation, some specications may change without notication.
Single Zone Art Cool
Premier Wall Mount
Single Zone Art Cool Premier Wall Mount
units are equipped with inverter components
that offer superior load matching and long
piping installation. The product works for
optimizing power consumption in residential
and small office buildings. Utilizing multiple
indoor wall mount units each with custom
temperature controls allow for precise
temperature settings in each zone of the
building. Art Cool Premier allows flexibility in
interior design and complements any decor.
Low Sound Levels
When outdoor units operate fully loaded, they
have one of the quietest sound levels. To
promote a quiet, comfortable environment, the
LG Single Zone Art Cool Premier indoor units
operate at sound levels as low as 25 dB(A)
(17dB(A) in sleep mode) and the outdoor
units as low as 45 dB(A) at full load.
All rotating components are soft-started by
the controller using digitally controlled invert-
ers, which reduce undesirable noise caused
by fans and compressors cycling on and off.
Comfort Control at Its
Best
Unlike traditional air conditioning control
systems, which use thermostatic controls
to maintain room temperatures, LG Single
Zone Inverter controls continuously vary the
indoor unit fan speed and refrigerant flow, in-
directly providing lower and more consistent
humidity levels in the conditioned space.
LG Single Zone one-to-one systems con-
tinuously measure the room temperatures
and adjust system operation accordingly to
maintain set temperature. The outdoor unit
adjusts operation by varying the compressor
speed and outdoor fan motors as needed
to maintain system operating pressure. As
a result, the Single Zone Art Cool Premier
Wall Mount system delivers targeted space
temperature control.
Inverter Driven
The twin-rotary compressor is optimized to
maximize compressor efficiency, which re-
duces power consumption and monthly utility
bills. This latest inverter technology allows
the LG Single Zone Art Cool Premier Wall
Mount outdoor unit to vary the compressor
motor shaft speed to deliver an appropriate
amount of cooling to the indoor unit. Precise
refrigerant volume delivery translates into
long periods with coil surface temperatures
below dew point and minimizes compressor
and fan component run time which may lead
to lower utility usage.
Simplified Installation
Cooling and heating systems that use the
LG Single Zone Art Cool Premier Wall Mount
product simplify and reduce the mechani-
cal and control system design time. The
designer no longer has to be concerned
with interconnecting chilled and condenser
water piping, air-distribution duct systems,
matching and selecting chillers, towers,
pumps, coils, fans, air handlers, or Variable
Air Volume (VAV) boxes.
Operating Range
The Single Zone Art Cool Premier Wall
Mount product has a nominal capacity range
of 3/4 to 1 ton (depending on outdoor/indoor
units).Operating ranges include:
Art Cool Premier Outdoor Units
Cooling: 14°F DB to 118°F DB
Heating: -13°F WB to 65°F WB
Compact Size
Single Zone Art Cool Premier Wall Mount
units are available in 3/4 to 1 tons. The out-
door units have a footprint of (WxHxD)
30 5/16 x 21 1/2 x 11 5/16.
Heat Transfer Efficiency
Fin Design with GoldFin™ Coating
All Single Zone Art Cool Premier Wall Mount
outdoor units are provided with large surface
coils made of copper tubes with louvered
aluminum fins designed to maximize unit
operating efficiency over a wide range of
ambient conditions.
Standard from the factory, every LG Single
Zone Art Cool Premier Wall Mount outdoor
coil fin surface is coated with LG’s exclusive
GoldFin™ anti-corrosive coating designed
to prevent natural surface corrosion of the
aluminum fins. This maintains heat transfer
properties of the coil for an extended time.
A hydrophilic coating is applied to the
outdoor unit coil fin surface over the GoldFin
coating. This coating enhances the develop-
ment of heavier water droplets gathering on
the fin surface. As a result, the droplets roll
off the fin surfaces, delaying the point when
frost forms on the coil surface during heat-
ing operation. This coating also makes it
possible to easily clean the outdoor unit coil
using a mild soap.
