This section of the manual describes the operation and use of a cab fitted tractor with an air conditioning system.
This air conditioning system, in addition to ensuring optimum temperature inside the cab, reduces air humidity, which
otherwise may be a nuisance to the operator and compromise safe tractor operation.
The cab's heating system utilizes the engine coolant for a heat source. The temperature control switch controls the
heat valve mechanically allowing the heat valve to open or close the flow of engine coolant to the heating coil located
in the upper rear of the cab. The heating and ventilation systems utilize the same fan and duct work as the air condi-
tioning system.
The cab is fitted with windows, which reduce the effects of the sun's rays inside the cab. The sun proof side panels,
roof, and flooring reduce noise to a minimum.
In addition the cab has recirculation air filters that provide filtration of the air coming into the cab from the outside, and
pressurization.
