54 Part Number 80-1505-3 6/11
Connect a vacuum pump to both of the line set shut-off
valves located at the back of the ice machine head
section or from the schrader valves located in the
CVD
®
Condensing Unit. Schrader valve core removal
tools (that allow for putting the cores back in without
removing vacuum pump hoses) will greatly decrease
evacuation time.
Evacuate to 500 microns (or less) at the CVD
condensing unit.
Isolate the vacuum pump from the line set shut-off
valves and/or condensing unit access ports prior to
proceeding.
