AIR CIRCULATION IN CABIN
CONTROL(D)
a - surrounding (outside) air is sucked in
through filters to cabin – sucking the
air from cabin is closed.
b - Air is sucked in from the space of the
cabin and again blown off to the
cabin (inner air recirculation for fast
adjustment of temperature in the
cabin)
The intake of air from the outside
of the cabin is completely locked
and there is no surplus pressure
in the cabin which would prevent
pervasion of unfiltered air to the
cabin!
Do not use this position of the
control with work of the tractor!
