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 Wall Mounted Extended Piping 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 Extended Piping systems’ advanced
controls provide exceptional building dehumidification and temperature control, and can rapidly adapt system operating parameters
to the ever changing building load. LG Single Zone Wall Mounted
Extended Piping 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.

Mounted Extended
Piping Systems
Single zone wall mounted extended piping
systems are 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.
Single zone systems are available in a
nominal capacity range of 2 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 mounted extended piping
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
Single Zone High Wall Mounted Extended Piping Engineering Manual
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.
Due to our policy of continuous product innovation, some specications may change without notication.

PRODUCT FEATURES AND BENEFITS
Single Zone Systems
Single zone wall mounted extended piping
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.
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. Occupants remain comfortable
while utility costs are reduced.
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 37 dB(A) and outdoor units
as low as 55 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 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
Single Zone Wall Mounted Extended Piping Engineering Manual
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 systems deliver precise
space temperature control.
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 2 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 65°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:
LSU243HLV, LSU303HLV, LSU363HLV
(WxHxD (in)) 34-1/4 x 31-1/2 x 12-5/8.
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.

• 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.
