OPERATING TIPS
Mode operation: AUTO
COOLING MODEL

temperature, the mode will switch between Cooling and
Drying.
HEAT & COOL MODEL (Reverse Cycle)
Auto changeover function
When AUTO CHANGEOVER is selected, the air condi-
tioner selects the appropriate operation mode (Cooling
or Heating) according to your room's present tempera-
ture.
When AUTO CHANGEOVER is fi rst selected, the fan will
operate at a very low speed for about a few minutes
while the unit determines the current conditions of the
room and selects the proper operation mode.
If the difference between thermostat setting and actual
room temperature is more than +4 °F

→ Cooling operation

If the difference between thermostat setting and actual
room temperature is within ±4 °F
→ Determined by outdoor temperature
If the difference between thermostat setting and actual
room temperature is more than –4 °F

→ Heating operation

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 out-
side 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 heat opera-
tion 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 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.
When the room temperature is near the thermostat set-
ting, 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 thermostat.
During Heating mode:
Set the thermostat to a temperature set-
ting 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/Dry mode:
Set the thermostat to a temperature set-
ting that is lower than the current room
temperature. The Cooling and Dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in Cooling mode, the fan alone will ope-
rate).
During Fan mode:
You can not use the unit to heat and
cool your room.
