Manufacturer Narrative

Qn#(b)(4).The sample was returned for evaluation.A visual exam was performed and there were no major defects observed.Functional testing was performed and the unit was connected to 120vac.The unit passed the initial power connect test and navigated through the power-on self-test (p.O.S.T.) with no issues.During the temperature display accuracy test the unit displayed the correct temperatures and properly alarmed in the high temperature scenario.The unit was then prepared for the functional bench test where a water reservoir bottle, an adult breathing circuit (880-36kit), a 382-10 conchasmart column, airflow, and dual temperature probes were connected to the unit.The settings were set to full rainout, invasive, at 37 degrees c.The unit shut off during the test.The unit was opened and the power supply board was replaced with a known good lab inventory power supply board.This time, the unit successfully navigated all pre-operational self-tests again and was functioning in real time.The unit functioned without any interruption and was able to heat up to the set temperature of 37 degrees c with the lab inventory power supply board.Testing confirms the unit had a faulty power supply board.The reported complaint has been confirmed.The sample was returned with a defective power supply pcba.A device history record review was performed with no evidence to suggest a manufacturing related issue.Each concha neptune device is inspected 100% during manufacturing assembly, it is unlikely that this defect was present at the time of release.The sample was manufactured in 2009 and was designed for a minimum of 5 years.Based on the information available, it appears that unintentional user error - normal wear caused or contributed to this event.Teleflex will continue to monitor and trend on complaints of this nature.
