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, 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.
These 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 these
systems.
The comprehensive study of this book will improve your knowledge about the system and its application in detail.
