What is “Catechin air fi lter” ?
Catechin is a biofl avonoid that is found in green tea that has both antiviral and antioxidant qualities. In addition to these benefi ts, Catechin also
offers excellent deodorizing characteristics. Catechin air fi lter uses this
compound to not only improve air quality but also prevent the spread of
bacteria and viruses in the room.
Important
• Clean the fi lters regularly for best performance and to
reduce power consumption.
• Dirty fi lters cause condensation in the air conditioner
which will contribute to the growth of fungi such as
mold. It is therefore recommended to clean air fi lters
every 2 weeks.

● OPERATING INSTRUCTIONS ●
WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Even if these items are checked, when the unit does not recover from the
trouble, stop using the air conditioner and consult your dealer.
Symptom Explanation & Check points
Indoor Unit
The unit cannot be operated. • Is the breaker turned on?
The unit cannot be operated
for about 3 minutes when
restarted.
Mist is discharged from the air
outlet of the indoor unit.
The swing operation of the
HORIZONTAL / VERTICAL
VANE is suspended for a
while, then restarted.
The air fl ow direction changes
during operation.
The direction of the horizontal
vane cannot be adjusted with
the remote controller.
The operation is stopped for
about 10 minutes in the heating operation.
The unit starts operation by
itself when the main power
is turned on, though it isn’t
operated with the remote
controller.
Outdoor Unit
The fan of the outdoor unit
does not rotate even though
the compressor is running.
Even if the fan starts to rotate,
it stops soon.
Water leaks from the outdoor
unit.
White smoke is discharged
from the outdoor unit.
• Is the power supply plug connected?
• Is the ON timer set? Page 7
• This protects the unit according to instructio ns from the microprocessor. Please
wait.
• The cool air from the unit rapidly cools mois-
ture in the air inside the room, and it turns
into mist.
• This is for the swing operation of the HORIZONTAL / VERTICAL VANE to be performed
normally.
• When the unit is operated in COOL or DRY
mode, if the operation continues with air
blowing down for 0.5 to 1 hour, the direction
of the air fl ow is automatically set to position
(1) to prevent water from condensing and
dripping.
• In the heating operation, if the air fl ow temperature is too low or when defrosting is being done, the horizontal vane is automatically
set to horizontal position.
• Defrosting of the outdoor unit is being
done.
Since this is completed in max.10 minutes,
please wait. (When the outside temperature
is too low and humidity is too high, frost is
formed.)
• These models are equipped with an auto restart function. When the main power is turned
off without stopping the unit with the remote
controller and is turned on again, the unit
starts operation automatically in the same
mode as the one set with the remote controller just before the shutoff of the main power.
Refer to “Auto restart function” Page 5 .
• When the outside temperature is low during cooling operation, the fan operates
intermittently to maintain suffi cient cooling
capacity.
• During COOL and DRY operations, pipe or
pipe connecting sections are cooled and this
causes water to condense.
• In the heating operation, water condensed
on the heat exchanger drips down.
• In the heating operation, the defrosting operation makes water frozen on the outdoor
unit melt and drip down.
• In the heating operation, vapor generated
by the defrosting operation looks like white
smoke.
