OPERATING MODES
READY Mode
This mode is entered automatically upon successful execution of power-on-self-test when
the unit is first turned on, or following DEFROST mode upon the cryoICE probe reaching
approximately 10°C(50°F) and automatically venting. This indicates that the system is ready for
the next cryoablation run.
FREEZE Mode
This mode is entered from the READY mode when the user initiates the cryoablation cycle by
pressing and releasing the Activation Button or the Footswitch. In this mode, the NO gas is
allowed to cycle through the cryoICE probe causing a temperature drop to take place at the
cryoICE probe.
DEFROST Mode
This mode is entered automatically from FREEZE mode upon expiration of the ablation timer,
or manually by the operator when the Activation Button or the Footswitch is actuated while in
the FREEZE mode. In this mode, the cryoICE probe temperature is actively forced towards the
ambient temperature. Once the cryoICE probe temperature is approximately 10°C(50°F), the
cryoICE BOX unit will transition back to the READY mode.
Note: cryoICE BOX does allow early transition out from the DEFROST mode into either the READY mode
or the FREEZE mode by pressing the Activation Button.
Note: cryoICE probe temperature may drop temporarily upon transition from DEFROST to READY state.
FAULT Condition
This is entered upon detection of any unrecoverable error condition during any mode. The
system is inoperable in this mode until the unit is first power cycled, and only if the FAULT
Condition no longer exists or has been remedied.
The cryoICE BOX operates in one of three modes: READY, FREEZE, DEFROST. These modes are identified by the system
status indicator LEDs and the ablation status indicator LEDs located on the front of the cryoICE BOX unit.

CYLINDER EXCHANGE
3. Turn OFF the cryoICE BOX power 4. Remove the heater band from
NO cylinder
5. Replace with a full cylinder and
re-connect the heater band
• The band should be located as
close to the bottom of the tank
as possible
• Fasten the outermost buckles
first and work toward the center
6. Open the NO tank valve 7. Power ON the cryoICE BOX 8. Press the RESET button on the
front of the cryoICE BOX
Valve icon will be amber and icon
will flash if tank valve is closed.

1. The gas gauge indicator can only be RESET once per Power Cycle
or if a tank change has been detected.
• It is recommended to start with a full NO tank.
• The gas gauge indicator will need to be RESET when a full
tank is installed and will not automatically adjust to full
without pressing RESET.
2. The cryoICE BOX needs time for the system to warm up in order
to estimate the NO remaining in the tank.
• This takes 2 to 5 minutes on average, depending on the
initial pressure of the NO tank. If the starting pressure is
below 725psi(5MPa) due to a cold environment, it could take
additional time to estimate the NO remaining.
• The gas gauge indicator requires the heater band to be
installed on the NO tank for proper functionality.
• If the gas gauge indicator is RESET prior to the system
warming up, it may indicate full until the tank pressure is
about 800psi (5.5MPa).
TANK CHANGE TIPS
1. Tank Closed Indicator
• The gas gauge indicator arrow and valve portion will flash
amber when the cryoICE BOX does not detect any pressure.
• Check the NO tank valve to see if it is closed. If so, open it to
turn off the Tank Closed Indicator.
2. Low Pressure Indicator
• The gas gauge indicator will flash regardless of the gas gauge
level indicator if the tank pressure is below 650psi(4.5MPa).
• This may be due to tanks being stored in a cold environment,
and it may take longer than normal for the heater to bring the
system up to pressure.

CRYOICE BOX TROUBLESHOOTING
The cryoICE BOX User Manual has been updated to include additional information in the Troubleshooting sections to
assist with maintaining Cryo system performance.
Possible Cause Action to Take
Pressure gauge less than 700psi(4.8MPa) and cylinder
warm • Replace the cylinder with a full one
Pressure gauge less than 700psi (4.8MPa) and cylinder
cold
• Verify heater band is working (warm to touch)
• Heater band icon is off, verify heater band connection
Pressure gauge is above 700psi (4.8MPa) in freeze
mode
• Unplug cryoICE BOX Orange tube, if temperature drops to -65°C(-85°F) the exhaust filter is
clogged – return cryoICE BOX
• Unplug Orange tube at cryoICE BOX, if temperature doesn’t drop to -65°C(-85°F) the Cryo
Probe is clogged – replace Probe
TOPIC #2: Cryo Probe Not Getting Cold Enough
Possible Cause Action to Take
Trapped NO within the system • Power-Off, Power-On cryoICE BOX – vents Probe side NO
ACM Blue connector sleeve out of sequence • Push the Blue connector sleeve toward cryoICE BOX
Connector O-ring dried out or swelling • Lubricate the O-ring with AtriCure P/N# C002502
TOPIC #3: Difficulty Connecting a Cryo Probe to the ACM
Possible Cause Action to Take
Heater band over temperature due to empty cylinder • Replace the cylinder with a full one
