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 3 for
instructions on changing the mode setting (COOL, FAN).

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 3 for instructions on changing the mode setting
(HEAT, COOL, FAN).

*Heating

● Always set the temperature higher than the current room temperature. If it is set lower than the current room temperature,
heating will not start.

● For about 3 to 5 minutes after starting heating, the fan will operate very slowly, then switch to the selected fan setting. This
period allows the indoor unit’s heat- exchanger to perform before emitting warm air.

● During defrosting (see page 13), the heating mode will be temporarily interrupted. DEFROST will be shown on the remote
controller display.

Cooling

● Always set the temperature lower than the current room temperature. If it is set higher than the current room temperature,
the unit will not enter the cooling mode and only the fan will operate.

Fan

● The room temperature cannot be adjusted in the FAN mode. (The room temperature is not displayed on the remote control­ler.)
