down so that the air speeds to every nook and corner of your
room.
REMOVABLE INTAKE GRILLE
The indoor unit’s Intake Grille can be removed for easy cleaning
and maintenance.
MILDEW-RESISTANT FILTER
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature is kept
constant at all times.
10°C HEAT OPERATION
The room temperature can be maintained at 10°C so as to prevent the room temperature from falling too far.
PROGRAM TIMER
The program timer allows you to integrate OFF timer and
ON timer operations in a single sequence. The sequence
can involve one transition from OFF timer to ON timer,
or from ON timer to OFF timer, within a twenty-four hour
period.
SLEEP TIMER
When the SLEEP button is pressed during Heating mode, the
indoor unit’s thermostat setting is gradually lowered during
the period of operation; during cooling mode, the thermostat
setting is gradually raised during the period of operation.
When the set time is reached, the indoor unit automatically
turns off.
The AIR FILTER has been treated to resist mildew growth, thus
allowing cleaner use and easier care.
SUPER QUIET OPERATION
When the FAN CONTROL button is used to select QUIET, the
indoor unit begins super-quiet operation; the indoor unit’s airflow
is reduced to produce quieter operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning filter uses static electricity
to clean fine particles and dust in the air such as tobacco smoke
and plant pollen that are too small to see.
The filter contains catechin, which is highly effective against
various bacteria by suppressing the growth of the bacteria adsorbed to the filter.
Note that when the air cleaning filter is installed, the amount of
air produced decreases, causing a slight decrease in the indoor
unit’s performance.
NEGATIVE AIR IONS DEODORIZING FILTER
It comprises pottery super micro particles which can produce
negative air ions having the effect of deodorizing and can absorb
and remit the peculiar smell at home.

TROUBLESHOOTING
WARNING!
In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power
Supply Plug, and consult authorized service personnel.
Merely turning off the indoor unit’s power switch will not completely disconnect the unit from the power
source. Always be sure to disconnect the Power Supply Plug or turn off your circuit breaker to ensure
that power is completely off.
Before requesting service, perform the following checks:
Symptom
NORMAL
FUNCTION
Doesn’t operate immediately:
Problem
● If the indoor unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to prevent
fuse blowouts.
● Whenever the Power Supply Plug is disconnected and then reconnected to a power outlet, the protection circuit will operate for about
3 minutes, preventing unit operation during that period.
Noise is heard:
● During operation or immediately after stopping the unit, the sound
of water flowing in the air conditioner’s piping may be heard. Also,
noise may be particularly noticeable for about 2 to 3 minutes after
starting operation (sound of refrigerant flowing).

—
● During operation, a slight squeaking sound may be heard. This is
the result of minute expansion and contraction of the front panel
due to temperature changes.
Smells:
Mist or steam is emitted:
● During Heating operation, a sizzling sound may be heard occasional.
This sound is produced by the Automatic Defrosting operation.
15
● Some smell may be emitted from the indoor unit. This smell is the
result of room smells (furniture, tobacco, etc.) which have been
taken into the indoor unit.
—
● During Cooling or Dry operation, a thin mist may be seen emitted
from the indoor unit. This results from the sudden cooling of room
air by the cool air emitted from the indoor unit, resulting in condensation and misting.
—
● During Heating operation, water may be produced from the outdoor
unit due to Automatic Defrosting operation.

OPERATING TIPS
Operation and Performance
Microcomputer-controlled Automatic Defrosting
Heating Performance
● This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat to
indoor unit. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insufficient
heating performance is being produced, we recommend you
use this air conditioner in conjunction with another kind of
heating appliance.
● Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time
may be required after first starting the air conditioner until the
room is heated.
● When using the Heating mode under conditions of low outdoor
temperature and high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this air
conditioner is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner
will temporarily stop, and the defrosting circuit will operate
briefly (for about 7-15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will flash.
AUTO Restart
In Event of Power Interruption
● The power supply to the air conditioner is stopped by a power
interruption. The air conditioner will then restart automatically
in its previous mode when the power is restored.
● If a power interruption occurs during TIMER operation, the timer
will be reset and the indoor unit will begin (or stop) operation at
the new time setting. In the event that this kind of timer fault occurs, the TIMER Indicator Lamp will flash (see Page. 3).
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily disconnect the Power Supply Plug, reconnect it, and then use the
Remote Control Unit to resume operation.

● If the air conditioner is used under higher temperature conditions than those listed, the built-in protection circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the air conditioner is used under conditions of lower temperature
than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
● Do not use this air conditioner for any purposes other than the Cooling, Heating, Dehumidifying, and air-circulation of rooms in
ordinary dwellings.
● If the air conditioner is used for many hours under high-humidity conditions about 80% or more, condensation may form on the
surface of the indoor unit, and drip onto the floor or other objects underneath. (About 80% or more)
