Qn#: (b)(4).The sample was returned for evaluation.A visual exam was performed and the trim ring was noted to be missing and there was a crack on the right back mounting bracket.No other defects were 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 prepared for the functional bench test where a water reservoir bottle, an adult breathing circuit (880-36kit), a 382-10 conchasmart column, and dual temperature probes were connected to the unit.Air flow was supplied to the unit for a real time operational scenario.Per the user manual, "heated wire circuits are required to change rainout settings", therefore the unit was set up for the bench test using heated wire circuits.The rainout settings were able to be adjusted normally.Based on the investigation performed, the reported complaint could not be confirmed.Functional testing did not reveal any operational anomalies.
