entilatio
The ventilation unit is housed in the cab ceiling.
To switch it on and adjust it, turn the electrical fan switch to the desired speed.
The cab becomes slightly pressurized when the ventilation system is in operation, so that the fresh air can
enter only by way of the filter installed in the rear section of the cab roof.
The fan switch can be operated only after the ignition key is inserted.
The air flow can be regulated and directed by suitable positioning the air diffusers.
Air can be taken in fresh from outside or recirculated from within the cab by way of the relative side inlets.
External Circulation
The air is supplied from outside the cab through the rear grille and filtered through a cab filter located behind
the grille.
*N.B: It is very important that the air diffusers never be completed closed so as to allow for a steady air flow.
To obtain a greater pressurization inside the cab, it is necessary to take the air from the outside, therefore
the inside air recirculatiing grille should be fully closed.
Circulation Diffuser
To recirculate the cab air, open the recirculated air inlets
on the side of the cab ceiling.
