OPERATION PROCEDURE
HEATING OPERATION WITH AUTO FAN MODE
This operation starts with the highest air flow in order to quickly raise the
room temperature. It will then automatically switch to a lower air flow to
quietly maintain the selected temperature.
HEATING OPERATION
Select the HEATING mode by pressing MODE button (2). Switch to the
desired FAN SPEED or to AUTO FAN by pressing FAN button (4). Select
suitable temperature setting. By selecting the HEATING mode, the air flap
will move automatically to vertical air delivery position, optimal for
heating.The HOT KEEP function is provided. The fan will be turned off
when the indoor coil temperature is not sufficiently hot to prevent
uncomfortable cold air drafts. In some models the HOT KEEP function is
operating in AUTO FAN mode only.
COOLING OPERATION WITH AUTO FAN MODE
This operation starts with the highest air flow in order to quickly lower the
room temperature. It will then automatically switch to the low air flow to
quietly maintain the selected temperature.
COOLING OPERATION
Select the COOLING mode by pressing MODE button (2). Switch to the
desired FAN SPEED or to AUTO FAN by pressing button (4). Select suitable
temperature setting. By selecting the COOLING mode, the air flap will move
automatically to horizontal air delivery position, optimal for cooling.
VENTILATING OPERATION
Select the ventilating mode by pressing MODE button (2). Switch to the
desired fan speed by pressing FAN speed button (4).
TURNING ON THE AIR CONDITIONER
Press START/STOP button (1) to turn the air conditioner on. The operation
indicator on the air conditioner will light up, indicating that the unit is in

the air conditioner will start and operate in the same mode and functions
prior to being turned off.
