• Do not apply excessive force on the fan as it may cause cracks or breakage.
Air cleaning fi lter
(Anti-Allergy Enzyme Filter, option)
Back side of air fi lter
Every 3 months:
• Remove dirt by a vacuum cleaner.
When dirt cannot be removed by vacuum cleaning:
• Soak the fi lter and its frame in lukewarm water before rinsing it.
• After washing, dry it well in shade. Install all tabs of the air fi lter.
Every year:
• Replace it with a new air cleaning fi lter
for best performance.
• Parts Number MAC-408FT-E
Important
• Clean the fi lters regularly for best performance and to re-
duce 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.
Pull to remove from the air fi lter
1. Lift the front panel until a “click” is heard.
2. Hold the hinges and pull to remove as shown in the illustration above.
• Wipe with a soft dry cloth or rinse it with water.
• Do not soak it in water for more than two hours.
• Dry it well in shade.
3. Install the front panel by following the removal proce-
dure in reverse. Close the front panel securely and

Hinge
Air fi lter (Nano platinum fi lter)
• 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 fi lter” ?
Nano platinum is a ceramic particle that includes a platinum nanoparticle.
The particles are incorporated into the fi lter material, which results in pro-
viding semi-permanent antibacterial and deodorizing characteristics for the
fi lter. Nano platinum surpasses the catechin (a biofl avonoid that is found
in green tea) in performance. Nano platinum fi lter uses this compound not
only to improve air quality but also to eliminate bacteria and viruses. This air
fi lter has a semi-permanent lasting effect even after washing it with water.

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?
• Is the power supply plug connected?
• Is the ON timer set? Page 6
The horizontal vane does not
move.
• Are the horizontal vane and the vertical vane
installed correctly?
• Is the fan guard deformed?
The unit cannot be operated
for about 3 minutes when
restarted.
• This protects the unit according to instruc-
tions from the microprocessor. Please
wait.
Mist is discharged from the air
outlet of the indoor unit.
• The cool air from the unit rapidly cools mois-
ture in the air inside the room, and it turns
into mist.
The swing operation of the
HORIZONTAL VANE is
suspended for a while, then
restarted.
• This is for the swing operation of the HORI-
ZONTAL VANE to be performed normally.
The air fl ow direction changes
during operation.
The direction of the horizontal
vane cannot be adjusted with
the remote controller.
• 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 upward
position to prevent water from condensing
and dripping.
The unit starts operation by
itself when the main power
is turned on, though it isn’t
operated with the remote
controller.
• These models are equipped with an auto re-
start 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 control-
ler just before the shutoff of the main power.
Refer to “Auto restart function”. Page 4
The indoor unit discolors over
time.
• Although plastic turns yellow due to the infl u-
ence of some factors such as ultraviolet light
and temperature, this has no effect on the
product functions.
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.
• When the outside temperature is low dur-
ing cooling operation, the fan operates
intermittently to maintain suffi cient cooling
capacity.
Water leaks from the outdoor
unit.
• During COOL and DRY operations, pipe or
pipe connecting sections are cooled and this
causes water to condense.
Remote controller
The display on the remote
controller does not appear or
it is dim. The indoor unit does
not respond to the remote
control signal.
• Are the batteries exhausted? Page 3
• Is the polarity (+, -) of the batteries correct?
Page 3
• Are any buttons on the remote controller of
other electric appliances being pressed?
Symptom Explanation & Check points
Does not cool
The room cannot be cooled
suffi ciently.
• Is the temperature setting appropriate?
Page 4
• Is the fan setting appropriate? Please
change fan speed to High or Super High.
Page 5
• Are the fi lters clean? Page 7
• Is the fan or heat exchanger of the indoor unit
clean? Page 7
• Are there any obstacles blocking the air inlet
or outlet of the indoor or outdoor unit?
• Is a window or door open?
• When a ventilation fan or a gas cooker is
used in a room, the cooling load increases,
resulting in an insuffi cient cooling effect.
• When the outside temperature is high, the
cooling effect may not be suffi cient.
• It may take a certain time to reach the setting
temperature or may not reach that depending
on the size of the room, the ambient tempera-
ture, and the like.
Airfl ow
The air from the indoor unit
smells strange.
• Are the fi lters clean? Page 7
• Is the fan or heat exchanger of the indoor unit
clean? Page 7
• The unit may suck in an odor adhering to the
wall, carpet, furniture, cloth, etc. and blow it
out with the air.
Sound
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 fl owing 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 fl owing
is heard.
• This is the sound of refrigerant or condensed
water fl owing in the unit.
Hissing sound is sometimes
heard.
• This is the sound when the fl ow of refrigerant
inside the unit is switched.
In the following cases, stop using the air conditioner and consult your dealer.
• When water leaks or drips from the indoor unit.
• When the upper operation indicator lamp blinks. Except for when the lamp of
a multi unit blinks while the unit is on standby.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic ON/
OFF type fl uorescent lamp (inverter-type fl uorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An ampli-
fi er may be required for the affected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.
