Duct Free Split (DFS) Technology
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 oc-
cupants 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.

ARCHITECTURAL APPEAL
Convergence of Technological Innovation with Flexibility and Style
Benefits of Single Zone Wall
Mount Systems
• Available from 9,000 - 33,000 Btu/h
• Inverter technology
• All season use - heat pump models for both
cooling and heating capabilities
• Operating range for outdoor units of 14°F to
118°F in cooling and -4°F to 75°F in heating
• Operating range for indoor units of 64°F to
90°F in cooling and 60°F to 86°F in heating
• Quiet operation inside and outside
• Duct-free split system
Single Zone Inverter
Wall Mount Systems
Single zone wall mount duct free split (DFS)
systems are among the industry’s best airconditioning 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.
Single zone systems are available in a
nominal capacity range of 3/4 to 2-3/4
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.
Adaptable and Flexible
Single zone wall mount duct-free split (DFS)
systems allow 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
• Place 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 Systems
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 systems allow flexibility in interior design and
complement 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 single zone
system indoor units operate at sound levels
as low as 24 dB(A) (High Efficiency Single
Zone) and outdoor units as low as 45 dB(A)
at full load (High Efficiency Single Zone).
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 to maintain
room temperatures, LG Single Zone Inverter
controls continuously adjust 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
Single Zone High Efciency, Standard and Extended Pipe Wall Mount Engineering Manual
and outdoor fan motors as needed to maintain system operating pressure. As a result,
the single zone systems deliver precise
space temperature control.
Inverter Driven
The rotary (9k-12k Btu/h systems) and twin
rotary (18k-36k Btu/h systems) 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. Occupants remain
comfortable while utility costs are reduced.
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 capacity range of 3/4 to 2-3/4 tons (depending on
outdoor/indoor units).
Operating ranges for single zone systems:
Cooling: 14°F DB to 118°F DB
Heating: -4°F WB to 75°F WB
Installing an optional Low Ambient Wind
Baffle Kit will allow operation down to 0°F in
cooling mode for all single zone systems.
Compact Size
Single zone outdoor units have the following
footprints:

Fin Design with GoldFin™ 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 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.
