Introduction
Preface
New era brings more sophisticated and advanced buildings which in turn demands specialized and optimized direct expan-
sion air conditioning systems. Also energy efficiency, environment friendly, low noise and low maintenance cost are the fea-
tures which are essential for these systems.
As a part of vertical integration LG makes all the key components in house, which gives an edge to LG to make better and
latest technology products with best quality in optimized time.
SINGLE ZONE systems with are equipped with DC inverter technology and R410A refrigerant is perfect solution to various
installation locations.
LG SINGLE ZONE system consists of a single common outdoor unit for single indoor unit, such as ceiling cassette.
This Engineering product data book incorporates information about the product itself, its installation and designing for
SINGLE ZONE system.
The comprehensive study of this book will improve your knowledge about the system and its application in details.

SINGLE ZONE
Step by step SINGLE ZONE system selection process (reference)
(1) Calculate or obtain the maximum heat load for the area(s) to be air conditioned
(2)
(3)
(4)
1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas
or alkaline gas, are produced.
2. If the outdoor unit is installed close to the sea shore, direct exposure to the sea breeze
should be avoided and choose an outdoor unit with anti-corrosion treatment.

Notes:
- Sound measured at 4.9ft away from the center of the unit.
- Data is valid at free field condition.
- Data is valid at nominal operation condition.
- Reference accoustic pressure 0dB=20μPa.
- Sound level will vary depending on a range of factors such as
the construction(acoustic absorption coefficient) of particular
room in which the equipment is installed.
- The operating conditions are assumed to be standard.
