The sample was returned for evaluation.A visual exam was performed and there were no defects observed and no odor was noted.Functional testing was performed and the unit was connected to 110vac.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 prepared for the functional bench test where water, an adult breathing circuit (880-36kit), 2-3 lpm of air pressure, and a 382-10 universal water column was connected to the unit for a real time operational scenario.The unit successfully negotiated all pre-operational self-tests again and was functioning in real time.The settings were set to full rainout, invasive, at 37 degrees c.The unit functioned without any interruption or functional anomalies for ~1.75 hours.No smell was noted.Based on the investigation performed, the reported complaint could not be confirmed.Functional testing did not reveal any operational anomalies.
