• Maximum amount of time the
refrigeration system can be exposed to
the atmosphere is 15 minutes.
• Purge line set with dry nitrogen while
brazing.
• Shutoff valves for the line set 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.
SF3000C has 2 suction lines and requires
2
installation of a tee at the condensing unit.

Description
Step 3 Pressure Test and Evacuate Line Set
and CVD Condensing Unit
• Shutoff valves for the line set must
remain closed until pressure testing and
evacuation are complete.
• Valve core removal tools that allow for
removal and installation of the valve
cores without removing hoses for the
manifold gauge set are recommended to
decrease the evacuation time.
• Pressure test at 150 psi (10.34 bar) for a
minimum of 15 minutes.
• Minimum evacuation level is 500
microns.
• Minimize the time the refrigeration
system is exposed to the atmosphere
(15 minutes maximum)
Pressure test the line sets and CVD
Condensing Unit with 150 psi
(10.34 bar) of dry nitrogen. Add nitrogen at
the shutoff valves for the line set located at
the back of the ice machine head section or
from the access valves located in the CVD
Condensing Unit. Complete the pressure
test, verify no leaks are present and remove
the nitrogen from the system before
connecting the vacuum pump. Connect
vacuum pump and evacuate system to
500 microns.
