About Mode Operation
AUTO:
Cooling Operation
COOLING MODEL
● When the room temperature is 2 °C higher than the set temperature, the mode
will switch between Cooling and Drying.
Dry Operation
Thermostat control
● 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 7 for
instructions on changing the mode setting (COOL, FAN).
2 °C
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 7 for instructions on changing the mode setting
(HEAT, COOL, FAN).
● Do not select AUTO CHANGEOVER if the difference in the environmental temperatures of the master and slave units is over
2 °C. (Otherwise, the indoor fan may not be controlled correctly.)
* 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 24), the heating mode will be temporarily interrupted. DEFROST will be
shown on the remote controller display **and indoor unit’s OPERATION indicator lamp (red) will flash.
* 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 alone will operate).
Cooling:
● Use to cool your room.
Fan:
● Use to circulate the air throughout your room.

CONSOLE/UNDER CEILING DUAL TYPE”.
WARNING!
Before requesting service, perform the following checks:
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.
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, 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 panel 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 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 2 and 16 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, DEFROST will
be shown on the remote controller display **and the OPERATION indicator lamp will flash.
● The fan may operate at very low speed 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.

OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Instructions relating to “the OPERATION indicator lamp” (**) are applicable to “CEILING SUSPENSION TYPE” and “FLOOR
CONSOLE/UNDER CEILING DUAL TYPE”.
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.
*Microcomputer-controlled Automatic Defrosting
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
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 4 to 15 minutes).
During Automatic Defrosting operation, DEFROST will be
displayed on the remote controller, ** and 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, or one of the fans may stop intermittently.
En-24
OPERATING TIPS
