Compressor Fitting HVAC: Description and Operation
The compressor manifold and tube assembly is attached to the A/C compressor 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 pressure cutoff switch. A long-travel Schrader-type valve stem core is installed in the
fitting so that the pressure cutoff switch can be removed without discharging the A/C system.
