Body (Cab) Ventilation
The cab is ventilated through the air vent in the middle part
of the cowl and the heater box shutters, and also through the
swivelling quarter-lights and drop windows of the cab doors. To
make the cab ventilation more effective, make use of the heater
fan, but for that shut off the cock on the cylinder head.
Fresh air is admitted into the sanitary and passenger
compartments through the swivelling quarter-lights of the side
glasses, and also through the heater box when the shutter is
completely open and the radiator is shut in. To make the
ventilation more effective, make use of the heater fan.
Ventilation of the cargo compartment is effected through the
shutters in the front and rear parts of the body side panels.
Body (Cab) Heating
The cab heating and defrosting of the windshield are effected
through the heater-radiator (Fig. 71) connected into the engine
cooling system in parallel with the main radiator.
The warm air is admitted either for demisting the windshield
completely or for heating the cab and demisting the windshield
depending upon the positions of the shutters 4 (Fig 71) and the
lid 3. Intensity of air flow could be controlled by the air vent lid
of the cowl.
Effective operation of the heater is insured when a tempera-
ture of coolant in the engine cooling system is not less than
80 °C. Check the coolant temperature in the engine cooling
system, adjust it by shutting the radiator shutter folds of the
cooling system.
