CAB AIR CIRCULATION CONTROLLER
(D)
a - The surrounding (outdoor) air is sucked
into the cab through the filter – suction
of air from the cab is closed
b -
The air is sucked from the cab interior
and expelled back to the cab (inner re-
circulation of air for the cab air fast
conditioning.
In this position the intake of air
from outside the cab is completely
closed and no overpressure is ge-
nerated in the cab for preventing
the nonfiltered air from entering
the cab!
Keep the controller in this position
for the indispensable period of
time only!
HEATING AND AIR CONDITIONING
SYSTEM PROPER OPERATION
For the heating of air conditioning proper
operation certain overpressure has to be
generated inside the cab. Therefore the
closing of all the windows, door, and the
cab roof cover is recommended.
CAB INTERIOR FAST HEATING
Proceed as follows:
1 - Turn the heating valve controller (A)
to the right (heating valve completely
open).
2 - Set the air circulation in the cab (D)
to the position of internal recircula-
tion.
3 - Select the appropriate fan speed with
the fan controller (B) (positions 1, 2,
