Manufacturer Reason
for Recall
The units may display the alarm "sampling line clogged" after the flow zeroing procedure that is conducted automatically 1 hour after start up. This could result in the potential of a small bias added to the CO2 measurement and affect the alarm notification.

Action The recall was initiated by telephone on March 30, 2015. Follow-up phone calls were made July 6, 2015. The firm was unable to provide a telephone script. The recalling firm also issued letters dated March 28, 2016, via email on April 6, 2016, dated July 11, 2016. The letters contained the same content, notified the customer of the issue, and informed them a fix was available. The notification instructs the customer to pass the information onto all other users, as well as any downstream customers if it was further distributed. The notification also informs the customer their response is required using the enclosed form and the return addressed envelope. The response form asks, in part, if they have the affected ISA CO2 sensors at their facility and are they interested in accepting the fix. If they decline the fix, they are asked to provide the reason why. For further questions, please call (877) 741-5369.
