99 General system fault
Please follow these instructions if any of the fault conditions listed above are displayed on the controller:
1. Thoroughly clean the warmer using the instructions provided in this manual (refer to section titled "Cleaning the enFlow IV fluid/blood warming system
components. " )
2. Evaluate the exterior of the device. If there is any physical damage to the housings or power cord that would allow fluid ingress into the device, or if
the heating element surface is physically damaged, deformed, or breached, then remove the device from service and return the device using the RGA
instructions provided in this manual (refer to "Servicing the enFlow IV fluid/blood warming system components. " )
3. If there is no obvious physical damage to the device, then evaluate the device using the instructions in Appendix E and Appendix F.
4. If the device passes the evaluation, then it may be returned to normal use.

Description
Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
Warmer internal operating voltage is out of range.
Warmer internal reference voltage is out of range.
Data is written to and then read from RAM and verified at power up.
A check sum is done on the memory at power up.
A check sum is done on the memory at power up.
This fault code is indicative of a non-recoverable heater over-temperature, fuse open, condition.
This fault occurs every time the covers are opened while heating.
This fault code is indicative of a Heater Over-temperature protection fault.
This fault is activated if the external crystal oscillator fails.
This failure is indicative of the Warmer being too hot inside and is caused by operating in an environment that
is too warm.
A system clock failure has occurred.
The Controller is unable to determine the fault.
