OPERATION
EXPLANATION OF COMPONENTS
AIR CONDITIONER SWITCH
This switch (2) is used to start or stop the cooling or dehumidifying
function.
When the fan switch is turned ON and the air conditioner switch is
pressed, the indicator lamp above the switch lights up. When the
switch is pressed again, the switch is turned OFF and the indicator
lamp goes out.
FRESH/RECIRC SELECTOR SWITCH
This switch (3) is used to select between recirculation of the air
inside the cab or intake of fresh air from outside.
When the switch is pressed, indicator lamp (A) at the top of the
switch lights up.
Recirculation of air inside cab
Press this switch (B) to use only the air inside the cab. Use this position to carry out rapid heating or cooling of the
cab or when the outside air is dirty.
Intake of fresh air from outside
Press this switch (C) to carry out heating or cooling with fresh air taken in from the outside. Use this position when
fresh air is taken in from outside the cab, or when removing the mist from the cab windows.
REMARK
When fresh air is taken into the cab, air pressure in the cab increases, which prevents the dust from entering. When
neither heating nor cooling is needed, bring in clean fresh air, with your preferred air flow, to prevent dust from
entering the cab.
