83. Air conditioner

Technical data

Important! These instructions present both the earlier air conditioner (refrigerant R12) and the later air conditioner
which has refrigerant R134a (Suva). The compressor and the drier reservoir have markings stating which one of
the refrigerants is in the system. If R12 refrigerant is replaced with R134a, see page 831/10. Tractors which have
the earlier air conditioner, the heater and air conditioner control panel is fitted on the front side of the cab roof. On
the later air conditioner, the control panel is placed on the RH side of the cab roof.
