Single Zone art cool Premier
general
LG Single Zone Art Cool Premier systems
are comprised of a single outdoor unit con-
nected 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 Art Cool Premier systems
are manufactured in a facility registered to
ISo 9001 and ISo 14001, which is a set of
standards applying to environmental protec-
tion 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.
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
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.
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
