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 briefl y (for about 4 to 15
minutes).
During Automatic Defrosting operation, the OPERATION indica-
tor lamp (green) will fl ash.
Low Ambient Cooling
● When the outdoor temperature drops, the outdoor unit's fans
may switch to Low Speed.
*Hot start (for heating)
● The indoor unit prevents cold drafts when heating operation
begins.
The indoor unit fan will not operate or it will operate at a very low
speed until the heat exchanger reaches the set temperature.
Mode operation: AUTO
COOLING MODEL
● When the room temperature is higher than the defi ned tem-
perature in temperature setting, the mode will switch between
Cooling and Drying.

Auto changeover function
● 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 fi rst selected, the fan will
operate at a very low speed for about 1 minute while the unit
determines the current conditions of the room and selects the
proper operation mode.
Room temperature is higher than the defi ned temperature in
temperature setting → Cooling mode or Dry mode
Room temperature is close to the defi ned temperature in
temperature setting → Determined by outdoor temperature
Room temperature is lower than the defi ned temperature in
temperature setting → Heating mode
● 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.
Defi ned temper-
ature in tem-
perature setting
● When the room temperature is near the temperature setting,
the air conditioner will begin monitor operation. In the monitor
operation mode, the fan will operate at a very low speed. If the
room temperature subsequently changes, the air conditioner
will once again select the appropriate operation (Heating or
Cooling) to adjust the temperature to the value set in the in-
door unit. (The monitor operation range is ±2 °C relative to the
temperature setting.)

About Mode Operation
*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
beginning 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 Automatic Defrosting
operation, the OPERATION indicator Lamp (green) will fl ash,
and the heat operation will be interrupted.
● After the start of heating operation, it takes sometime before
the room gets warmer.
Cooling:
● Use to cool your room.
Dry:
● Use for gently cooling while dehumidifying your room.
● You cannot heat the room during Dry mode.
● During Dry 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 adjusting room humidity.
● The fan speed cannot be changed manually when Dry mode
has been selected.
Fan:
● Use to circulate the air throughout your room.
During Heating mode:
Set the temperature to a temperature setting that is higher than the
current room temperature. The Heating mode will not operate if the
preset temperature is set lower than the actual room temperature.
During Cooling/Dry mode:
Set the temperature to a temperature setting that is lower than the cur-
rent room temperature. The Cooling and Dry modes will not operate if
the preset temperature is set higher than the actual room temperature
(in Cooling mode, the fan alone will operate).
During Fan mode:
You can not use the unit to heat and cool your room.
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.
● Should a power failure occur during TIMER operation, the timer
will be reset and the unit will begin (or stop) operating under
the new timer setting. In this event, the TIMER indicator lamp
(orange) will fl ash.
● 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.
