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 dif-
ferent 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 Wall Mounted Art Cool™ Premier air-source systems
offer the opportunity to minimize ductwork in the same configuration.
The systems offer zoning without the need for zone damper systems.
LG Single Zone Wall Mounted Art Cool Premier systems’ advanced
controls provide exceptional building dehumidification and tempera-
ture control, and can rapidly adapt system operating parameters
to the ever changing building load. LG Single Zone Wall Mounted
Art Cool Premier systems are easy to design, install, and maintain.
The modular design allows occupants to control their environmental
condition, providing individualized control of the setpoint temperature
and allowing occupants 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.

Convergence of Technological Innovation with Flexibility and Style
Single Zone Wall
Mounted Art Cool
Premier Systems
Choosing an LG Single Zone Wall Mount-
ed Art Cool Premier product provides a
system designer an edge to engineer
a system with individual control, and
design flexibility with advanced controls.
These single-zone systems are avail-
able in a nominal capacities of 3/4 to 2
tons. 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 Mounted Art Cool Premier out-
door and indoor units are available in
208–230V/60Hz/1Ph.
Adaptable and Flexible
Single zone wall mounted split systems
allow cooling or heating for the entire
residence or just a single room without
the need for invasive ductwork. 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
• House 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.

PRODUCT FEATURES AND BENEFITS
Single Zone
Wall Mounted Art Cool
Premier
Single zone systems 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. Single zone sys-
tems allow flexibility in interior design and
complement any decor.
Low Sound Levels
When outdoor units run at full load, they
have a quiet operating sound level. To pro-
mote a quiet, comfortable environment, the
LG single zone system indoor units operate
at sound levels as low as 25 dB(A) (17 dB(A)
in sleep mode) and the outdoor units as low
as 45 dB(A) at full load. All rotating compo-
nents are soft-started by the controller using
digitally controlled inverters, which reduce
undesirable noise caused by fans and com-
pressors 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.
LG single zone one-to-one systems continu-
ously measure the room temperatures and
adjust system operations accordingly to
maintain set temperature.
The outdoor unit responds by varying the
compressor speed and outdoor fan mo-
tors as needed to maintain system operat-
ing pressure. As a result, the single zone
systems deliver targeted space temperature
control.
Inverter Driven
The twin rotary compressors are optimized
to maximize compressor efficiency, which
reduces power consumption and monthly
utility bills. This latest inverter technology
allows single zone system outdoor units 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 us-
age.
Simplified Installation
Cooling and heating applications that use
single zone systems simplify and reduce the
mechanical 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
Single zone systems have a nominal capac-
ity range of 3/4 to 2 tons (depending on
outdoor/indoor units).
Outdoor unit operating ranges for single
zone systems:
Cooling: 14°F DB to 118°F DB
Heating: -13°F WB to 65°F WB
(Installing an optional Low Ambient Wind
Baffle Kit will allow operation down to 0°F in
cooling mode for these single zone sys-
tems.)
Compact Size
Single zone outdoor units have the following
footprint:
LAU090HYV1, LAU120HYV1:
(WxHxD [in.]) 30-5/16 x 21-1/2 x 11-5/16.
LAU150HYV2, LAU180HYV2
(WxHxD [in]) 34-1/4 x 31-1/2 x 12-5/8.
LAU180HYV1, LAU240HYV1
(WxHxD [in]) 34-1/4 x 31-1/2 x 12-5/8.
Fin Design with Gold-
Fin™ Coating
All single zone 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 single zone
outdoor unit coil fin surface is coated with
LG’s exclusive GoldFin™ anti-corrosive
coating designed to prevent natural surface
corrosion of the aluminum fins. This main-
tains 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.

Voltage tolerance is ±10%.
Maximum allowable voltage unbalance is 2%.
MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOP) is calculated as follows: (Largest motor FLA x 2.25) + (Sum of
other motor FLA) rounded down to the nearest standard fuse size.

• Measurements are taken 3.28 ft away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of ±3.
• Sound pressure levels are tested in an anechoic chamber under
ISO Standard 3745.
• Sound level will vary depending on a range of factors including the
construction (acoustic absorption coefficient) of a particular room in
which the unit was installed.
