PRESSURE TEST AND EVACUATE THE LINE SET
AND CVD CONDENSING UNIT
Schrader valve core removal tools that allow for
removal and installation of the valve cores without
removing manifold gauge set hoses are recommended
to decrease the evacuation time.
Leave the line set shut-off valves closed (front seated).
All CVD condensing units manufactured after
December 2009 contain a check valve in the
compressor discharge line. The check valve
requires an additional connection on the condensing
unit during evacuation and recovery procedures.
Connections are required at five points:
