50Hz •R410A •Heat Pump Features & Benefits
Plasma Air Purifying Kit (Accessory)
The PLASMA Air Purifying Function not only removes
microscopic contaminants and dust, but also removes
house mites, pollen, and pet fur helps to prevent
allergic diseases like asthma.
High Head Drain
Pump(Accessory:700mm)
In some of the places natural drainage is not possi-
ble. For such places drain pump is very useful. It
removes condensed water from the unit.
Zone Control(Accessory)
It controls the temperature of each zone. Opening or
closing of the damper is controlled by sensing the
temperature of each zone. In the cooling mode, if the
temperature of a particular zone is lower than set
temperature then the damper is closed. On the other
hand if the temperature of a particular zone is higher
than the set temperature, damper is opened to pro-
vide cooling to the zone and vice versa in the heating
mode.

LG’s High Technology provide Easy and Low cost Design
of Duct work
Generally, when External Static Pressure increases
air volume decreases. But by controlling the phase of
motor while installing the product E.S.P. is controlled
from 8~10 mmAq linearly. E.S.P. control provides
required constant air volume irrespective of ESP
change. Desired ESP can also be set through LCD
wired remote control. Setting of the desired ESP
gives required combination of ESP and airflow.
