Cole Parmer CG-500 User manual

1300-87052QSG-1G, REV 3 Cole-Parmer®
Step 1. Connect the powercord to the AC Inlet located at the back of unit. Power On the CG-500 FM. When
the power is switched ON at the back of the mill, “FreezerMill” appears during start-up as the software loads.
Then the screen will switch to the Home Screen. From the Home screen the Control Panel, Saved Protocols,
Run History, and Settings can be accessed by touching the buttons displayed.
Step 2. Fill the tub manually with liquid nitrogen to the fill mark (approx. 2 inches below lip of the tub).
Always close the lid slowly to avoid splashing of LN and latch down. It is normal to see a visible vapor
stream exiting the vent at the back of the unit. Do not block the vent. See Manual, Section 4.3 LN Tank
connection.
How To Operate CG-500 Freezer/Mill
Set up the CG-500 FM in a well ventilated,
unconfined space. The Freezer/Mill should be run on
an open countertop, in ambient air, with
recommended maximum relative humidity 70% from
5°C –31°C (40°F –88°F).
When working with liquid nitrogen directly or
indirectly, the LN Tank valve or hose, or chilled
Freezer/Mill components, cryogenic gloves must be
worn to protect hands. A face shield is recommended
to protect eyes from possible splashing. Wear the
proper protection equipment (PPE).
