Zetor Proxima CL 80, Operator'S Manual

Operation of heating or air-condition with tractor´s work
When the internal air recirculation is switched on, the fresh
air supply is closed and the cabin space is exhaled by the
operator. This condition can cause tiredness and can
cause dust to enter the cab due to loss of overpressure in
the cab.
Note: When the tractor is in operation, the fan should
draw air from the outside of the cab through filters to
ensure overpressure in the cab. Do not use internal air
circulation.
When spraying pesticides and using an active
carbon heater filter, the recirculation control (D) must
be in the 'air is drawn from the outside' position and
the fan control (B) must be in the 'maximum fan
operation' position to create overpressure in the cab.
