general
LG Single Zone Art Cool Premier system
comprises of a single outdoor unit connected
to a single indoor unit with a single refriger-
ant circuit.
An LG Single Zone Art Cool Premier system
is a DFS system that can operate in either
cooling or heating mode. The system
shall be capable of changing mode within
a maximum time of three (3) minutes to
ensure indoor temperature can be properly
maintained.
LG components are manufactured in a
facility registered to ISo 9001 and ISo
14001, which is a set of standards ap-
plying 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 for cooling; -13°F to 75°F for heating
operating ranges for Indoor Units of 64°F to
90°F for cooling; 60°F to 86°F 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
(variable from 10 to 115Hz, modulate in 1
Hz increments). over-current protection and
vibration isolation are integrated with the
compressor.
outdoor unit Coil
Heat Pump outdoor unit coils are 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 drive,
variable speed propeller type fan.
The Brushless Digitally Controlled (BLDC)
fan motor shall have inherent protection, per-
manently 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
The unit is available in 208-230V 60 Hz,
1-phase power supply. The unit is capable of
operating within voltage limits of ±10% rated
voltage, and include overcurrent protection.
Controls
The unit is factory wired with necessary
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.
