general
LG Single Zone Art Cool Mirror system
comprises a single outdoor unit connected to
a single indoor unit with a single refrigerant
circuit.
An LG Single Zone Art Cool Mirror system
is a DFS system that can operate in either
cooling or heating mode. The system is
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 apply-
ing to environmental protection set by the
International organization for Standardiza-
tion (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; 5°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
rotary (9k/12k Btu/h systems) or twin-rotary
(18k.24k Btu/h systems) compressor to
modulate capacity (modulation in 1 Hz
increments).
Frequency ranges for the outdoor units are:
9k Btu/h = 25 to 107 Hz
12k Btu/h = 25 to 107 Hz
18/24k Btu/h = 10 to 100 Hz
over-current protection and vibration isola-
tion 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 elec-
trical control components, integral micropro-
cessors, 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.
