Introduction
Preface
New era brings the more sophisticated and advanced buildings which in turn demands for specialized and optimized direct
expansion air conditioning systems. Also energy efficiency, environment friendly, low noise and low maintenance are the
features which are essential for these systems.
As a part of vertical integration LG makes all the key components in house, which gives us an edge to LG to make better
and latest technology products with best quality in optimized time.
and systems are equipped with inverter technology and R410A refrigerant which is perfect solution
to various installation locations.
This Engineering product data book incorporates information about the product itself, and installation, designing for
and system.
The comprehensive study of this book will improve your knowledge about the system and its application in detail.
