MECHANICAL SPECIFICATIONS
General
LG Single Zone High Efficiency Wall Mount systems are comprised
of a single outdoor unit connected to a single indoor unit with a
single refrigerant circuit.
These single zone systems can operate in either cooling or heating
mode. These systems are capable of changing mode within a
maximum time of three (3) minutes to ensure temperature can be
properly maintained.
LG Single Zone High Efficiency systems are manufactured in
a facility registered to ISO 9001 and ISO 14001, which is a set
of standards applying to environmental protection set by the
International Organization for Standardization (ISO). The units are
listed by Intertek Electrical Testing Laboratories (ETL) and bear the
ETL label. Wiring in these units are in accordance with the National
Electrical Code (NEC).
Temperature Ranges
Outdoor Unit
Operating ranges for outdoor units of 14°F to 118°F DB for cooling
and -4°F to +65°F WB for heating.
Indoor Unit
Operating ranges for indoor units of 53°F to 75°F WB for cooling and
60°F to 86°F DB for heating.
Installing an optional Low Ambient Wind Baffle Kit will allow operation
down to 0°F in cooling mode for these single zone systems.
Casing / Frame
Outdoor unit is constructed with pre-coated metal (PCM). Indoor unit
is constructed of heavy duty Acrylonitrile Butadiene Styrene (ABS)
and High Impact Polystyrene (HIPS) plastic.
Refrigerant System
The refrigeration system consists of a single refrigeration circuit and
uses R410A refrigerant. The outdoor unit is provided with factory
installed components, including a refrigerant strainer, four-way
reversing valve, electronic controlled expansion valve (EEV), high and
low side charging ports, service valves, and interconnecting piping.
Refrigeration Oil Control
Heat pump outdoor units have a centrifugal oil separator and
controls to ensure sufficient oil supply is maintained, and that oil
does not travel with the refrigerant.
Compressors
The outdoor unit is equipped with one hermetic digitally controlled
inverter driven twin rotary compressor to modulate capacity
(modulation in 1 Hz increments).
Frequency ranges for the outdoor units are as follows:
LSU090HSV5 = 10-84 Hz
LSU120HSV5 = 10-92 Hz
LSU180HSV5 = 10-93 Hz
Overcurrent protection and vibration isolation are integrated with the
compressor.
Outdoor Unit Coil
Heat pump outdoor unit coils are made of a nonferrous construction
with louvered fins on copper tubing, and are protected with an
integral coil guard. Coil fans have a factory applied corrosion
resistant GoldFin
TM
material with hydrophilic coating. Drain pan
heaters are also available for the outdoor units—9,000 and 12,000
Btu/h outdoor units include factory-installed drain pan heaters; the
drain pan heater for the 18,000 Btu/h outdoor unit is offered as an
optional accessory
Fans and Motors
The outdoor unit includes one direct fan drive, variable speed
propeller type fan. The Brushless Digitally Controlled (BLDC)
fan motor shall have inherent protection, permanently lubricated
bearings, and variable speed with a maximum speed up to 950 rpm.
Raised guards are provided to limit contact with moving parts. The
outdoor unit has horizontal discharge airflow.
Electrical
These units are available in 208-230V, 60 Hz, 1-phase power supply.
These units are capable of operating within voltage limits of ±10%
rated voltage, and include overcurrent protection.
Controls
The indoor unit casing has a factory-standard, integral, infrared
sensor designed to communicate with the supplied LG wireless
handheld remote controller. An optional LG supplied wired controller
is available as an additional accessory. Communication between the
indoor unit and the outdoor unit is accomplished through 18 AWG
four-core, stranded, shielded power / communication cable. HSV5
indoor units have built-in Wi-Fi and can be controlled by LG’s Smart
ThinQ™ app on a smart device. A field-supplied Wi-Fi network and
smart device are required. The Smart ThinQ app is free, and is
available for Android™ and iOS. (Android is a trademark of Google
