4.0 SETTING UP
The 6875D Freezer/Mill weighs 78 pounds (35.38 Kg) empty. The lid opens from the front with
the lid latch in the center. The AC Input module and the ON/OFF switch (which also serves as a
circuit breaker) are on the back of the cabinet. The vent for the liquid nitrogen tub is on the
back of the cabinet where the vent hose assembly is attached. There are gas springs on both
sides of the cabinet to control the movement of the lid. The touchscreen, controller is affixed
to the top of the lid and linked to the unit by a RJ45 Ethernet cable connector. At the back of
the controller is an USB Port to download run data, or to upgrade software.
Caution:
4.1 Electrical Connection
Plug the electrical cord into the AC Inlet on the back of the Freezer/Mill cabinet, and then into a
standard 3-prong grounded electrical outlet. The 230V/50HZ 6875D Freezer/Mill is supplied
with a standard European 2-prong plug with cord. For the 230V/50HZ version, make sure the
cord and plug conform to local electrical codes.

Do not tip the Freezer/Mill on its side to drain liquid nitrogen
out of the tub. Damage can occur to the mill preventing it from
operating. In a well vented room, raise the lid to its full upright
position and allow the liquid nitrogen to evaporate.
