About AUTO CHANGEOVER Operation [REVERSE CYCLE MODEL]
● When AUTO CHANGEOVER operation is selected, the air
conditioner selects the appropriate operation mode (Cooling or Heating) in response to your room’s temperature.
● When AUTO CHANGEOVER operation first selected, the
fan will operate at very low speed for about one minute,
during which time the unit detects the room conditions
and selects the proper operating mode.
● When the air conditioner has adjusted your room’s temperature to near the thermostat setting, it will begin monitor operation. In the monitor operation mode, the fan will
operate at low speed. If the room temperature subsequently changes, the air conditioner will once again select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the thermostat.
(The monitor operation range is ±2 °C relative to the thermostat setting.)

About Mode Operation
Cooling
● Use to cool your room.
Drying
● Use for gently cooling while dehumidifying your room.
● You cannot heat the room during Drying mode.
● During Drying mode, the unit will operate at low speed;
in order to adjust room humidity, the indoor unit’s fan
may stop from time to time. Also, the fan may operate at
very low speed when detecting room humidity.
● The fan speed cannot be changed manually when Drying
mode has been selected.
Fan [COOLING MODEL]
● When using a space heater to heat the room, using the
air conditioner’s Fan setting will help prevent warm air
from collecting near the ceiling, and thus assist in distributing warm air evenly throughout the room.
● Fan operation will begin automatically when the room
temperature rises above the set temperature, and stop
when the temperature falls below the set temperature.
● If the air emitted from the unit feels too cold, increase the
temperature setting.

Example: When set to COOL
Fan [HEAT & COOL MODEL (Reverse Cycle)]
● Use to circulate air through your room without changing
its temperature.
*Heating
● Use to warm your room.
● When Heating mode is selected, the air conditioner will
operate at very low fan speed for about 3 to 5 minutes,
after which it will switch to the selected fan setting. This
period of time is provided to allow the indoor unit to warm
up before begin full operation.
● When the room temperature is very low, frost may form
on the outside unit, and its performance may be reduced.
In order to remove such frost, the unit will automatically
enter the defrost cycle from time to time. During defrost
cycle, the red OPERATION indicator will flash, and the

CARE AND MAINTENANCE
Cleaning the Intake Grille
1. Removing the Intake Grille
1 Press in both lower edges of the intake grille until you
hear a clicking sound and open the grille.
2 Open the grille farther.
3 Lift up the intake grille until it can be removed (the
grille cannot be removed unless it is raised sufficiently).
2. Cleaning the Intake Grille
Use a vacuum cleaner to remove dust accumulations,
then wipe the grille with a clean cloth dipped in warm
water; wipe with a clean dry cloth to remove any water.
3. Installing the Intake Grille
1 Hold the intake grille horizontally and fasten the two
hooks on the front panel.
Cleaning the Air Filter
If dirt is allowed to collect in the air filter, the airflow will be
reduced, leading to reduced performance, and increased
operating noise. Be sure to clean the filters at the beginning
of the operating season, and about every two weeks during
periods of frequent operation.
1. Removing the Air Filter
1 Remove the intake grille.
2 Hold on to the air filter handles and pull up slightly to
release the two lower hooks. Then pull the air filter
down and out.

TROUBLESHOOTING
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the elec-
WARNING!
Before requesting service, perform the following checks:
trical breaker or disconnect the power supply plug, and consult authorized service personnel.
Merely turning off the unit’s power switch will not completely disconnect the unit from the power
source. Always be sure to turn off the electrical breaker or disconnect the power supply plug to
ensure that power is completely off.
NORMAL
FUNCTION
Symptom
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
Problem
● If the 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 electrical breaker is turned off then on again or the
power supply plug is disconnected and then reconnected, the protection circuit will operate for about 3 minutes, preventing unit
operation during that period.
● During operation and 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 coolant flowing).
● During operation, a slight squeaking sound may be heard. This is
the result of minute expansion and contraction of the front cover
due to temperature changes.
*● During Heating operation, a sizzling sound may be heard occa-
sional. This sound is produced by the Automatic Defrosting operation.
● 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 air conditioner.
● 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 air emitted from the air conditioner, resulting in
condensation and misting.

Airflow is weak or stops:
Water is produced from
the outdoor unit:
*● During Heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to Automatic
Defrosting operation.
*● When Heating operation is started, fan speed is temporarily very
low, to allow internal parts to warm up.
*● During Heating operation, if the room temperature rises above
the thermostat setting, the outdoor unit will stop, and the indoor
unit will operate at very low fan speed. If you wish to warm the
room further, set the thermostat for a higher setting.
*● During Heating operation, the unit will temporarily stop opera-
tion (between 6 and 12 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, the OPERATION
indicator lamp will flash.
● The fan may operate at very low speed during Dry operation or
when the unit is monitoring the room’s temperature.
● In the monitor AUTO operation, the fan will operate at very low
speed.
*● During Heating operation, water may be produced from the out-
door unit due to Automatic Defrosting operation.

OPERATION DETAILS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Please read and understand the following details regarding this air conditioner.
Malfunction
Nearby lightning or use of a mobile radio (short wave, etc.) may result in malfunction. In this case, disconnect the power plug
from its outlet and connect it again, then use the remote control unit to resume operation.
Auto Restart
● The air conditioner power has been interrupted by a power failure. The air conditioner will then restart automatically in its
previous mode when the power is restored.
● Operated by settings before the power failure.
Then, the airflow-direction louvers will automatically change to their standard direction.
● If a power failure occurs during timer operation, the timer will be reset and the unit will begin (or stop) operation at the new
time setting. In the event that this kind of timer fault occurs, the TIMER indicator will flash.

OPERATION DETAILS
Operation and Performance
*Heating Performance
● This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. 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 Indoor and Outdoor Temperatures are High
When both indoor and outdoor temperatures are high during use of the heating mode, the outdoor unit’s fan may stop
at times.
*Microcomputer-controlled Automatic Defrosting
When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the
outdoor unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
unit 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 6 to 12 minutes).
During Automatic Defrosting operation, the OPERATION indicator lamp (red) will flash.
*Low Ambient Cooling
When the outdoor temperature drops, the outdoor unit’s fans
may switch to Low Speed.
