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!
F_02_17b
It is necessary to create surplus pressure in the cabin for
proper function of the heating or air-condition. We
therefore recommend you to close all the windows and
doors and tilting cover of the cabin.
