Restrictor And Reservoir (With Internally Regulated Compressor)

Pressures, Checking For Vehicles With Restrictor And Reservoir (with Internally Regulated Compressor)

NOTE:
- Connecting service station. Pressures, Checking on Vehicles
- Observe test conditions. Refrigerant Circuit, Checking Pressures (Using Service Station)

- Set engine speed to 2000 rpm.
- Observe pressure gauge of service station.

NOTE:
- 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 inaccessible connection at compressor or reservoir (measurement accuracy). Only applies to certain vehicles Heating, air conditioning or Air conditioning.

Specifications

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
