CLEANING
Instructions:
• Switch off the power supply or turn off the breaker before cleaning.
• Be careful not to touch the metal parts with your hands.
• Do not use benzine, thinner, polishing powder, or insecticide.
Air filter (Nano platinum filter)
• Clean every 2 weeks
• Remove dirt by a vacuum cleaner, or rinse with water.
• After washing with water, dry it well in shade.
What is “Nano platinum filter”?
Nano platinum is a ceramic particle that includes a platinum nanoparticle.
The particles are incorporated into the filter material, which results in providing semi-permanent antibacterial and deodorizing characteristics for the
filter. Nano platinum surpasses the catechin (a bioflavonoid that is found
in green tea) in performance. Nano platinum filter uses this compound not
only to improve air quality but also to eliminate bacteria and viruses. This air
filter has a semi-permanent lasting effect even after washing it with water.
• Use only diluted mild detergents.
• Do not expose parts to direct sunlight, heat, or fire to dry.
• Do not use water hotter than 50°C.
Air cleaning filter
(Electrostatic anti-allergy enzyme filter,
option)
Every 3 months:
• Remove dirt by a vacuum cleaner.
When dirt cannot be removed by vacuum cleaning:
• Soak the filter and its frame in lukewarm water before rinsing it.
• After washing, dry it well in shade. Install
all tabs of the air filter.
Every year:
• Replace it with a new air cleaning filter
for best performance.
• Parts Number MAC-2320FT
Pull to remove from the air filter
Important
• Clean the filters regularly for best performance and to
reduce power consumption.
• Dirty filters cause condensation in the air conditioner
which will contribute to the growth of fungi such as
mold. It is therefore recommended to clean air filters
every 2 weeks.
Front panel
1. Lift the front panel until a “click” is heard.
2. Close the front panel securely and press the
positions indicated by the arrows.

• Do not soak the front panel in water.
Important
• The surface of the indoor unit is easily scratched, so
never rub or hit the unit with something hard. Also,
when installing or removing the front panel, handle it
with care to prevent scratches on it.
• Do not use abrasive cleaner to prevent scratches on the
surface of the indoor unit.
• It is very easy to get fingerprints on the surface of the
indoor unit. When fingerprints are noticeable, gently
wipe them off with a soft dry cloth.
• When using a commercially available chemical impregnated cloth, follow its instructions.

Airflow
The air from the indoor unit
smells strange.
Cracking sound is heard.
• This sound is generated by the expansion/contraction of the front panel, etc. due to change in
temperature.
“Burbling” sound is heard.
• This sound is heard when the outside air is
absorbed from the drain hose by turning on the
range hood or the ventilation fan, making water
flowing in the drain hose to spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
Mechanical sound is heard
from the indoor unit.
• This is the switching sound in turning on/off the
fan or the compressor.
The sound of water flowing
is heard.
• This is the sound of refrigerant or condensed
water flowing in the unit.
Hissing sound is sometimes
heard.
• This is the sound when the flow of refrigerant
inside the unit is changed.
Timer
Weekly timer does not operate according to settings.
• Is the ON/OFF timer set? Page 6
• Transmit the setting information of the weekly
timer to the indoor unit again. When the information is successfully received, a long beep will
sound from the indoor unit. If information fails to
be received, 3 short beeps will be heard. Ensure
information is successfully received. Page 7
• When a power failure occurs and the main power
turns off, the indoor unit built-in clock will be
incorrect. As a result, the weekly timer may not
work normally.
Be sure to place the remote controller where
the signal can be received by the indoor unit.

Water leaks from the outdoor
unit.
• 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
ice forming on the outdoor unit melt and drip down.
White smoke is discharged
from the outdoor unit.
• In the heating operation, vapor generated by the
defrosting operation looks like white smoke.

Installation place
Avoid installing the air conditioner in the following places.
• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where oil is splashed or where the area is filled with oily smoke (such as cooking areas and factories, in which the properties of plastic could be changed
and damaged).
• Where there is high-frequency or wireless equipment.
• Where the air from the outdoor unit air outlet is blocked.
• Where the operation sound or air from the outdoor unit does not bother the
house next door.
The installation location of the outdoor unit should
be at least 3 m away from the antennas for TV sets,
radios, etc. In areas where the reception is weak,
provide greater space between the outdoor unit and
the antenna of the affected device if operation of the air
conditioner interferes with radio or TV reception.
Remove all batteries from the remote controller.
When using the air conditioner again:
