CONTROL OF AIR CIRCULATION IN
CAB (D)
a - surrounding (outer ) air is sucked
through filters into the cab - air suction
from the cab is closed.
b - air is sucked from the cab space
and again blown into the cab (inner air
re-circulation for fast temperature ad-
aptation in cab).
In this position the air inlet from
outside of the cab is fully closed
and in the cab no overpressure,
which prevents penetration of
non-filtered air into the cab, is
created!
Use this position of the control
only for urgently necessary time!
RIGHT FUNCTION OF HEATING AND
AIR-CONDITIONING SYSTEM
It is necessary to create overpressure in
the cab for proper function of heating or
air-conditioning. Therefore we recom-
mend to shut all windows, doors and cab
roof cover.
FAST HEATING THE CAB SPACE
Process in the following way:
1 - Turn the control of the heating valve
(A) to the right-hand position (heating
valve fully open).
2 - Set the control of air circulation in the
cab (D) to the position of inner re-
circulation.
3 - Choose the desired blower speed
(position 1, 2, 3) by the blower switch
(B).
4 - Set outlets to desired angle to avoid
direct blowing to persons in the cab.
5 - Switch over the control lever of the
heating valve (A) to the left-hand po-
sition.
