Compressor - Valtra 6000 Workshop Manual

83. Air conditioner

Compressor

The service valves (D and S) are fitted on the pipe
connectors on air conditioners that have refrigerant
R134a as in figure below
If the compressor should be changed, contact an expert
who knows refrigerating systems.
A new compressor is filled with 2,0 dl oil in the factory.
Drain the oil in the new compressor. 1,6 dl oil must run
out. Pour the oil back to the compressor and fit the
plug. If the drained oil amount was not 1,6 dl, add or
reduce the oil volume to 1,6 dl (on account of the inter-
nal build ---in, all oil in the compressor does not run out).
Note! If the system is opened and refrigerant changed,
the compressor oil should also be changed. In this
case, fill the compressor with 2,0 dl oil.
Detach the new compressor protective caps very care-
fully so that the threads and connections do not
damage.
Tightening torques:
--- 3/4" connection on pressure side 24,5 ---29,5 Nm.
--- 7/8" connection on suction side 29,5 ---33,5 Nm.
