Single Zone Mega, Standard Efficiency, and Mega 115V

MECHANICAL SPECIFICATIONS

General

LG Single Zone Mega, Standard Efficiency,

and Mega 115V Wall Mounted systems

comprise of a single outdoor unit connected

to a single indoor unit with a single refriger-

ant circuit.

This system is a Duct-Free Split system

that can operate in either cooling or heat-

ing mode. The system shall be capable of

changing mode within a maximum time of

three (3) minutes to ensure indoor tempera-

ture can be properly maintained.

The system is manufactured in a facility reg-

istered to ISO 9001 and ISO 14001, which is

a set of standards applying to environmental

protection set by the International Orga-

nization for Standardization (ISO). Wiring

in these units are in accordance with the

National Electrical Code (NEC).

Temperature Ranges

Mega (HEV2, HFV3)

Operating ranges for outdoor unit of 14°F to

118°F (DB) for cooling; 14°F to 65°F (WB)

for heating.

Operating ranges for indoor unit of 53°F to

75°F (WB) for cooling; 60°F to 86°F (DB) for

heating.

Mega 115V (HXV2)

Operating ranges for outdoor unit of 14°F to

118°F (DB) for cooling; 14°F to 65°F (WB)

for heating.

Operating ranges for indoor unit 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,

accumulator, four-way reversing 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 (HEV2, HFV3)

ODUs are:

9k Btu/h = 10 to 70 Hz (cooling); 10 to 92 Hz

(heating)

12k Btu/h = 10 to 74 Hz (cooling); 10 to 98

Hz (heating)

18 Btu/h = 10 to 70 Hz (cooling); 10 to 87 Hz

(heating)

24k Btu/h = 10 to 76 Hz (cooling); 10 to 95

Hz (heating)

Frequency ranges for the (HXV2) ODUs are:

9k Btu/h = 10 to 74 Hz (cooling); 10 to 98 Hz

(heating)

12k Btu/h = 10 to 74 Hz (cooling); 10 to 98

Hz (heating)

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 has inherent protection, perma-

nently 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 HEV2 or HFV3 model unit is available

in a 208-230V 60 Hz, 1-phase power supply.

The HXV2 model unit is available in a 115V

60 Hz, 1-phase power supply. The units are

capable of operating within voltage limits of

±10% rated voltage, and include overcurrent

protection.

Air Filter

Return air inlet has a fctory-supplied primary

removable, washable filter. Filters are ac-

cessed from the front of the unit without the

use of tools.

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.
