About Mode Operation
AUTO:
COOLING MODEL
• When the room temperature is 2 °C higher than the set temperature, the mode will
switch between Cooling and Drying.
• During the Drying mode operation, the FAN setting should be switched to LOW for
a gently cooling effect during which the fan may temporarily stop rotating.
• If the mode automatically selected by the unit is not satisfactory, see page 4 for
instructions on changing the mode setting (COOL, FAN).

Setting temperature
AUTO (* AUTO CHANGEOVER):
HEAT & COOL MODEL (Reverse cycle)
• When AUTO CHANGEOVER is selected, the air conditioner selects the appropriate operation mode (Cooling or Heating) according
to your room’s present temperature.
• When AUTO CHANGEOVER is first selected, the fan will operate at very low speed for about one minute while the unit determines
the current conditions of the room and accordingly selects the proper operation 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.)
• If the mode automatically selected by the unit is not satisfactory, see page 4 for instructions on changing the mode setting (HEAT,
COOL, FAN).
* 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 defrosting (see page 11), the heating
mode will be temporarily interrupted. The defrost indicator will be turn on the remote
controller display.
Cooling:
• Use to cool your room.
Fan:
• Use to circulate the air throughout your room.
* During Heating mode:
Set the thermostat to a temperature
setting that is higher than the current
room temperature. The Heating mode
will not operate if the thermostat
is set lower than the actual room
temperature.
During Cooling mode:
Set the thermostat to a temperature
setting that is lower than the current
room temperature. The Cooling mode
will not operate if the thermostat
is set higher than the actual room
temperature (in Cooling mode, the fan

OPERATING DETAILS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Operation and Performance
* Heating Performance
● This air conditioner uses a heat pump which absorbs heat
from outside air and brings it indoors. As a result, its heating
performance is reduced as the temperature of outside air
drops. If you find that insufficient room heat is produced, we
recommend that you use the air conditioner together with
other heating appliances.
● Heat-pump type air conditioners use warm-air recirculation to
warm your entire room. As a result, some time will be required
after starting operation until your entire room becomes warm.
* Microcomputer-controlled Automatic
Defrosting
When the outside temperature is low and the humidity high, frost
will collect on the outside unit, reducing heater efficiency. When
this happens, the computer will automatically start the defrost
cycle. During the defrost cycle, the indoor fan will shutdown and
the defrost indicator of the remote controller will turn on. It will
take anywhere from 4 to 15 minutes before the air conditioner
starts up again.
Low Ambient Cooling
* 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.
When the outdoor temperature drops, the outdoor unit’s fans
may switch to Low Speed, or one of the fans may stop intermittently.
AUTO Restart
In Event of Power Interruption
● Should the power supply to the air conditioner be interrupted
by a power failure, the air conditioner will restart automatically
in the previously selected mode once the power is restored.
● 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 turn off the circuit breaker
turn it on again and then use the remote controller to resume
operation.
Group Control
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same settings.

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 electrical
breaker, 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 to ensure that power is completely off.

See Page
● 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, 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 occasionally. This sound is produced by the Automatic Defrosting
operation.
11
Smells:
● 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.
—
Mist or steam are
emitted:
● During Cooling 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.
—
*● During Heating operation, the outdoor unit’s fan may stop, and steam
may be seen rising from the unit. This is due to the Automatic Defrosting
operation.
