Hose/Line HVAC: Description and Operation
Main Climate Control
NOTE: Installation of a new suction accumulator 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 suction accumulator.
The condenser to evaporator line contains high pressure liquid refrigerant upstream of the evaporator core orifice tube.
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.
