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!
CORRECT FUNCTION OF THE
HEATING AND A/C SYSTEMS
It is necessary to create overpressure in
the cabin for correct function of heating
or air-conditioning. Therefore it is rec-
ommended to close all windows, doors
and upper cover.
FAST WARMING-UP OF THE CABIN
SPACE
Proceed as follows:
1. Turn the heating valve control (A) to
the right (fully open heating valve).
2. Set the air circulation in the cabin
control (D) to position of inner recir-
culation.
3. Select the desired speed of the fans
(position 1, 2, 3) using the fan control
(B).
4. Adjust angles of the air outlets to
prevent direct blowing of persons in
the cabin.
