CONTROL OF AIR CIRCULATION IN
THE CABIN (D)
a - Ambient (outdoor) air is sucked
through the filters into the cabin; suck-
ing of air from inside is closed;
b - Air is sucked from inside and ex-
hausted to the cabin again (inner cir-
culation for fast adjustment of tem-
perature in the cabin).
Intake of air from outdoor is com-
pletely closed and there is no
overpressure in the cabin to pre-
vent penetration of non-filtrated
air into the cabin!
Use this control position for nec-
essary period only!
