Hose/Line HVAC: Description and Operation
Main Climate Control
REFRIGERANT LINES
NOTE: Installation of a new receiver/drier is not required when repairing the air conditioning system except when there is physical evidence of
system contamination from a failed A/C compressor or damage to the receiver/drier.
The compressor manifold and tube assembly is attached to the A/C compressor, is sealed with O-ring seals, and has the following features:
-
The upstream side contains low pressure refrigerant gas.
-
The downstream side contains high pressure refrigerant gas and a fitting used to mount a serviceable high-pressure A/C charge port valve.
-
The downstream side also contains a fitting used to mount the A/C high pressure cutoff switch. A long-travel Schrader-type valve stem core is
installed in the fitting so that the A/C high pressure cutoff switch can be removed without discharging the A/C system.
