Mechanical Specifications - LG ART COOL LA150HYV2 Engineering Manual

General
LG Single Zone Wall Mounted Art Cool
Premier 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 sys-
tems are capable of changing mode within
a maximum time of three (3) minutes to
ensure indoor temperature can be properly
maintained.
LG Single Zone Wall Mounted Art Cool
Premier systems are manufactured in a facil-
ity registered to ISO 9001 and ISO 14001,
which is a set of standards applying to envi-
ronmental 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; -13°F to 65°F WB
for heating.
Indoor Unit
Operating ranges for Indoor Units of 53°F to
75°F WB for cooling; 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 sys-
tems.)
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 refriger-
ant. The outdoor unit is provided with factory
installed components, including a refrigerant

strainer, check valves, oil separator, accu-
mulator, 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 suf-
ficient 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:
LAU090HYV1, LAU120HYV1 - 10-115 Hz
LAU150HYV2, LAU180HYV2 - 10-115 Hz
LAU180HYV1, LAU240HYV1 - 10-115 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 fins have a factory
applied corrosion resistant GoldFin™ mate-
rial with hydrophilic coating.
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.
Due to our policy of continuous product innovation, some specifications may change without notification.

Single Zone Wall Mounted Art Cool Premier
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
These units are factory wired with neces-
sary electrical control components, integral
microprocessors, printed circuit boards,
thermistors, sensors, terminal blocks, and
lugs for power wiring.
Microprocessor-based algorithms provide
component protection, soft-start capability,
refrigeration system pressure, temperature,
defrost, and ambient control.
