1. FEATURE
FEATURES
Original plasma air cleaning unit effectively cleans the air in the room.
Super quiet
ALL DC
More compact compared with conventional model
Front view
Air flow mode can be set in 4 steps and more detailed air flow setting is possible.
When operation starts, the machine operates at high voltage and high power 
and when operation stabilizes, the set temperature is maintained at low voltage.

Washable filter
Restored to the same performance 
as when new each time it is washed.
Plasma unit
Mounts a plasma air cleaning unit.Minute dust 
particles are collected by an electrostatic filter and odor 
is suppressed by decomposition of foul odors by very 
weak ions. Since a filter with a lower ventilation 
resistance than in the past is used, high dust collection 
design simultaneously cleans in the air in the room.
V-PAM technology makes a compressor more powerful.

Bacteria grows in beading, 
and it causes bad odor.
Drying operation for 
approx. fifteen minutes.

Ozone bacteria eliminating operation 
for approx. fifteen minutes.
“Inner drying operation” and 
“ozone bacteria eliminating 
operation” keep the inside 
of the air conditioner clean 
at all times. That’s why air 
from the air conditioner is 
always clean and high 
efficiency is realized.
After operation ends, 
start approximately 
30 minutes speed 
cleaning operation 
by merely pressing 
the COIL DRY 
button.
Removes moisture.
Bacteria elimination
Covered with beading.
Easy maintenance
Easy maintenance and always clean. Troublesome maintenance has been made easy.
Since the front panel is easy to remove, maintenance is also easy.
Inner drying operation and plasma effect
This model is equipped with an inner drying function. After the power is turned off, the dry operation starts 
inside the air conditioner. The plasma air cleaning unit eliminates bacteria, deodorizes, and keeps 
the interior of the air conditioner clean by generating ozone and ions.
Low outdoor air temperature cooling correspondence
Corresponds to cooling operation at -10
°C 
outdoor air temperature
Corresponds to maximum 20m long piping

This button is used when installing the 
conditioner, and should not be used under normal conditions, as it will cause the 
air conditioner’s thermostat function to operate incorrectly.
If this button is pressed during normal operation, the unit will switch to test operation mode, and the Indoor Unit’s OPERATION Indicator Lamp and TIMER Indicator
