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.
