CAUTION: Turn the Visual-ICE Cryoablation System ON before connecting the gas cylinders to ensure the proper
diagnostic tests are conducted�
NOTE: If cryoablation needles with i-Thaw Function are being used, only argon gas is required to be connected� If
helium gas is connected, i-Thaw Function is disabled and only thawing with helium gas is available�
1� Position the gas cylinder(s) close enough to the Visual-ICE Cryoablation System to ensure that the gas supply
line is not stretched and does not present a trip hazard�
2� On the rear of the Visual-ICE Cryoablation System, ensure that the Manual Vent Valve is in the CLOSED position�
3� Remove the humidity covers from the helium and argon inlets on the Visual-ICE Cryoablation System�
4� Secure the safety cable at the end of the gas supply line to the system�
WARNING: Ensure that the safety cable is properly secured to the system in case the gas supply line
becomes accidentally disconnected.
5� Connect the helium high-pressure gas supply line to the helium inlet of the Visual-ICE Cryoablation System
using the quick-connect connector located at the rear of the system�

1 Safety cable
2 Quick-connect connectors
6� Route the helium gas supply line through the supply line clip on the System�
7� Connect the helium high-pressure gas supply line to the helium cylinder by securing the gauge assembly
adapter onto the cylinder connection (Figure 7)�
NOTE: Gas cylinder connections have left-handed threads�
