OPERATING TIPS
Mode operation: AUTO
About Mode Operation
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.
*Heating:l Use to warm your room.
l When Heating mode is selected, the air conditioner will stop 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.
l 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 heat operation will
be interrupted.
l After the start of heating operation, it takes sometime before the room
gets warmer.
Cooling: l Use to cool your room.
Dry: l Use for gently cooling while dehumidifying your room.
l You cannot heat the room during Dry mode.
l During Dry mode, the unit will operate at low speed; in order to adjust
room humidity, the indoor units fan may stop from time to time.
l The fan speed cannot be changed manually when Dry mode has been
selected.
Fan: l Use to circulate the air throughout your room.
COOLING MODEL
l When the room temperature is 2 °C higher than the set
temperature, the mode will switch between Cooling and
Drying.
l 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.
l 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 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. (The monitor operation
range is ±2 °C relative to the thermostat setting.)
l Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
l 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, reconnect it, and then use
the remote control unit to resume operation.
