Single Zone Art Cool

Mirror Wall Mount Engineering Manual

General

LG Single Zone Art Cool Mirror 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 heat-

ing 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 Art Cool Mirror 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 Interna-

tional 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 opera-

tion 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 re-

versing 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 con-

trols 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 (modula-

tion in 1 Hz increments). Frequency ranges for the outdoor units are:

LSU090HSV5 = 10-84 Hz

LSU120HSV5 = 10-92 Hz

LSU180HSV5 = 10-93 Hz

LAU240HSV3 = 10-100 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 inte-

gral coil guard. Coil fans have a factory applied corrosion resistant

GoldFin

material with hydrophilic coating.

Drain pan heaters are also available for the outdoor units. 9,000 and

12,000 Btu/h outdoor units include a factory-installed drain pan heat-

er. The drain pan heater for 18,000 and 24,000 Btu/h outdoor units is

offered as an optional accessory.

Fans and Motors

The outdoor unit includes one direct fan drive, variable speed pro-

peller 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 and shielded power/communication cable.

HSV5 indoor units have built-in Wi-Fi and can be controlled by LG’s

SmartThinQ™ app on a smartphone. A field-supplied Wi-Fi network

and smart device are required. The SmartThinQ app is free and is

available for Android™ and iOS.
