Convergence of Technological Innovation with Flexibility and Style
Single Zone Wall 
Mounted Extended 
Piping Systems
Single zone wall mounted extended piping 
systems are among the industry’s best 
air-conditioning units. Choosing an LG 
single zone wall mount product provides 
a system designer an edge to engineer a 
system with individual control, and design 
flexibility with advanced controls. 
Single zone systems are available in a 
nominal capacity range of 2 to 2-3/4 tons. 
These are best suited for applications 
with zones that require heating or cooling, 
such as residential, and small business 
office buildings. Single zone wall mount 
outdoor and indoor units are available in 
208–230V/60Hz/1Ph. 
Adaptable and Flexible
Single zone wall mounted extended piping 
systems allow cooling or heating for the  
entire residence or just a single room  
without the need for evasive ductwork. 
There is no tearing down of walls or alter-
ing the homes appearance. Long refriger-
ant piping lengths allow for extra design 
flexibility in indoor unit installation.
These units may be used for a number of 
residential or commercial environments
such as:
• Older homes
• New home construction
• Office buildings
• Restaurants
• Hospitals / Medical facilities
• Schools
• Nursing homes
• Retail establishments
• Place of worship
Inverter Technology
Inverter variable-speed DFS systems are 
measurably quieter and consume less 
energy than conventional air condition-
ers. The inverter compressor ramps up or 
down to match the required room capacity 
and maintain the comfort level. When the 
selected temperature is reached, the in-
verter compressor operates at low speed 
to maintain that comfort level, thereby 
using less energy.
