Key features
01
Design and function
R410A inverter outdoor units for cooling only. Multi V 5 Pro II offers Dual Sensing Control, a Black Fin heat exchanger and multi-module combination configurations.
02
Dual Sensing Control
Temperature and humidity sensing adapts operation to indoor conditions. The catalogue requires a Standard III wired remote controller for this function; the controller is sold separately.
03
Black Fin heat exchanger
The Black Fin coating is described as improving resistance to environmental corrosion, including salt and pollutants. Installation and maintenance must still account for actual site conditions.
04
Cooling-only configurations
The ARUV models in this catalogue are cooling-only units, including single and multi-module configurations. Multi V i heating ratings do not apply to Multi V 5 Pro II.

Applications & layout
Consider for offices, hotels, retail or multi-zone projects according to equipment type. Heat load, installation position and usage determine the appropriate solution.
Selection considerations
Check model codes, power supply, connection ratios, accessories and rating conditions. Actual capacity must account for piping length, height difference and working temperatures using LG documentation or selection software.

Rated values depend on test conditions and system combinations. Confirm optional features against the supplied configuration. The source document and edition are recorded for each model on this page.
The Vietnamese and English editions use matching verified model codes; each language links to its corresponding catalogue. Dimensions are reordered from the manufacturer’s W × H × D to the website’s H × W × D.
The indoor-unit count in parentheses is a conditional connection limit, not the default allowance. Combination sound-pressure ratings retain the manufacturer’s table values and are not arithmetic sums of component levels.
