Troubleshooting

The warming unit software routinely checks unusual operating conditions. If
such a condition occurs, the system may trigger a fault condition and alarm.
The warming unit can be reset by disconnecting the warming unit from the
main power source and allowing 30-60 seconds for the system to reset. If
the fault code condition reoccurs, disconnect again and wait 5 minutes for
the system to reset. If the fault condition reoccurs upon connection to the
main power source, the warming unit may have a hard-fault or permanent
error. Contact 3M technical support. If the fault does not reoccur upon
connection to the main power source, the warming unit may have a
cautionary fault.
Replace warming unit hose. Refer to service manual or IFU included with
replacement part for instructions.
Replace elbow sensor. Refer to IFU included with replacement part
for instructions.
Reattach warming unit hose.
Calibrate and return to service.
