Step 4 Connect the line set
• Maximum amount of time the refrigeration system
can be exposed to the atmosphere is 15 minutes
• Purge line set with dry nitrogen while brazing.
• Line set shut off valves on the ice machine must
remain closed and be protected from heat during
brazing.
• The condensing unit ships with a 50/50 mixture of
nitrogen/helium.
• S3000C/SF3000C has 2 suction lines and requires
installation of a tee at the condensing unit.
Step 5 Pressure Test and Evacuate Line Set and
CVD Condensing Unit
• Lineset shutoff valves must remain closed until
pressure testing and evacuation are complete.
• 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.
• Pressure test @ 150 psi (1000 kPa) for a minimum of
15 minutes.
• Minimum evacuation level is 500 microns.
