1.2. Technical data compressors
Important:
In order to avoid leakages on shaft packing of the compressor you have to distinguish two different
cases:
1. If the vehicle itself is withdrawn from operation for a longer time, it is also not necessary to switch
on the compressor.
2. If the vehicle is used for a longer time without using the cooling unit, it is recommended to acti-
vate the compressor every two weeks. Otherwise the shaft packing of the compressor could be
damaged by vibrations of the motor.
Refrigerant R134a
The chlorine-free refrigerant R 134a is used for charging the air conditioner. The traditional refriger-
ant R 12 is replaced by R 134a. Air conditioners already charged with R 12 should not be recharged
nor newly charged with R 134a. This is also valid for components used with R 12. They should not
at all be used in units to be charged with R 134a.
Mineral oils used in units with R 12 must not be used in units with R 134a. In this case synthetic oils
are to be used. The application of mineral oils in connection with R 134a would cause a break down
of the compressor, as the miscibility of mineral oil and R 134a and, thus the refrigerant circuit, are
not ensured.
