-
Switching pressures for refrigerant circuit switches are vehicle-specific.
-
Connection with valve for low-pressure switch or at evaporator is only to be used for vehicles with no service connection on low-pressure side
and an inaccessible connection at compressor or reservoir (measurement accuracy). Only applies to certain vehicles.
Specified values:
High pressure side:
Increasing from initial pressure (on connecting pressure gauges) to max. 20 bar.
Low pressure side:
Decreasing from initial pressure (on connecting pressure gauges) to value in graph.
A -
High pressure (measured at service connection) in bar
B -
Low pressure (measured at connection with valve at compressor or reservoir) in bar.
C -
Permissible tolerance range.
D -
Low pressure (measured at connection with valve for low-pressure switch or at service connection) in bar.
E
-
Permissible tolerance range.
