AtriCure cryoICE BOX Set-Up and Preparation
This section will outline the preliminary set-up for the cryo ICE BOX, including cylinder installation, heater band
installation, turning on the cryo ICE BOX, and resetting the cylinder gauge on the cryo ICE BOX user interface.
Note:
The cryo ICE BOX should be set up at least 15-minutes prior to the procedure to allow time for the
heater to warm the N
2
O cylinder to operating temperature.

O Cylinder Installation
•
Use only nitrous oxide gas with a water content not exceeding 3 ppm. Automotive grade nitrous ox -
ide should not be used due to the inclusion of hydrogen sulfide.
• The cryo ICE BOX is designed to use 20-pound (9-kg.) cylinders.
•
Always install a completely full cylinder so the cylinder volume can be indicated correctly.
• To install a new N
2
O cylinder, first find the N
2
O gas line receptacle on the rear panel and connect this
end into the corresponding end of the N
2
O gas line. Insert and push in the connector until you hear it
“click” in place and the connection is fully seated and secured from unlatching as seen below in Figure 4.

O Inlet Connection
•
Next, match the opposite black knob end of the N
2
O gas line with the threaded connection port of a new
N
2
O gas cylinder.
• Screw the cryoICE BOX gas line into place by hand tightening the country specific coupler as shown in
Figure 5.
Over tightening this fitting with a wrench may cause damage, allowing N
2
O gas to leak.
• To open gas cylinder valve, slowly turn the knob on the top of the cylinder counter-clockwise as seen in
Figure 6.
