Duct-Free Split (DFS) Systems
LG HVAC systems offer a range of solutions that are cost efficient,
quiet and attractive. Duct-Free Split (DFS) 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 occupants to condition only the occupied zones.
Quality Commitment
LG is committed to the success of DFS 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 DFS 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.

Wall Mount
The Single Zone Art Cool Mirror Wall
Mount Duct Free Split (DFS) System is
among the industry’s best air-conditioning units. Choosing an LG Single Zone
Wall Mount product provides a system
designer an edge to engineer a system
with individual control, and design flexibility with advanced controls. The Art
Cool Mirror Outdoor and Indoor units are
available in a nominal capacity range
of 3/4 ,1, 1 1/2 and 2 tons. These are
best suited for applications 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.
•Quiet operation inside and outside
•Duct Free Split system
Art Cool Mirror Wall Mounted Engineering Manual
Adaptable and
Flexible
The Single Zone Wall Mount DFS
System allows cooling or heating for the
entire residence or just a single room
without the need for evasive ductwork.
There is no tearing down of walls or
altering the homes appearance.
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 DFS 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 Art Cool
Mirror Wall Mount
Single Zone Art Cool Mirror 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 Mirror 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
in the industry. Sound is almost undetectable during off-peak operation. To promote
a quiet, comfortable environment, the LG
Single Zone Art Cool Mirror indoor units operate at sound levels as low as 24 dB(A) and
outdoor units as low as 45 dB(A) at full load.
LG customers often ask if the outdoor unit is
running after commissioning is complete.
All rotating components are soft-started
by the controller using digitally controlled
inverters, which reduce undesirable noise
caused by fans and compressors cycling on
and off.
Comfort Control at Its
Best
Tight temperature control through precise
load matching maximizes the time that the
indoor units remove moisture.
Unlike traditional air conditioning control
systems, which use thermostatic controls
Art Cool Mirror Wall Mounted Engineering Manual
to maintain room temperatures, LG Single
Zone Inverter controls continuously vary the
indoor unit fan speed and refrigerant flow, indirectly providing lower and more consistent
humidity levels in the conditioned space.
The longer the indoor coil temperature is
below the dew-point of the room in
conjunction with air movement across the
coil, the space humidity level will vary little,
compared to technologies that cycle fans
and compressors on and off multiple times
per hour.
The outdoor unit responds by varying the
compressor speed and outdoor fan motors
as needed to maintain system operating
pressure. As a result, the Single Zone Art
Cool Mirror Wall Mount system delivers
precise space temperature control.
Inverter Driven
The rotary (9k/12k Btu/h systems) and twinrotary (18k/24k Btu/h systems) compressor
is optimized to maximize compressor efficiency, which reduces power consumption
and monthly utility bills. This latest inverter
technology allows the LG Single Zone Art
Cool Mirror 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. Occupants remain comfortable
while utility costs are reduced.
Simplified Installation
Cooling and heating systems that use the
LG Single Zone Art Cool Mirror Wall Mount
product 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
The Single Zone Art Cool Mirror Wall Mount
product has a nominal capacity range of 3/4,
1, 1 1/2 and 2 tons (depending on outdoor/
indoor units). Operating ranges include:
Art Cool Mirror Outdoor Units
Cooling: 14°F DB to 118°F DB
Heating: 5°F WB to 75°F WB
Compact Size
Single Zone Art Cool Mirror Wall Mount outdoor units have the following footprints.

Heat Transfer Efficiency
Fin Design with GoldFin™ Coating
All Single Zone Art Cool Mirror Wall Mount outdoor units are provided with large surface coils
made of copper tubes with louvered aluminum
nsdesignedtomaximizeunitoperatingefciencyoverawiderangeofambientconditions.
Standard from the factory, every LG Single
Zone Art Cool Mirror 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 development 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 heating operation. This coating also makes it
possible to easily clean the outdoor unit coil
using a mild soap.
