The reported issue was confirmed.The root cause of the reported issue could not be determined.A potential root cause of the reported issue could be due to an overfill of the device.However, this cannot be confirmed.During evaluation, it was determined to be too much water in the device.T4 (chiller water tank temperature) rose along with the main tank temperature as it heated even though the mixing pump was off.This indicates the two tanks were mixing together.Confirmed heating problem in patient data files dated 10/10/ 2022.In manual normothermia mode a commanded temperature of 40 degrees c was not achieved.Preventatively replaced the level sensor.The double bend tube and the chiller evaporator outlet tubing appears distended/expanded.The device underwent pm servicing while in for repair.Serviced circulation pump and mixing pump replaced heater, double bend tube, and replacing both manifold o-rings and drain valves.The arctic sun 5000 passed all performance testing, calibration and electrical safety tests and is functioning properly and ready for use.The did not meet specifications and was influenced by the reported failure.The device was in use on a device patient.The dhr is not required as this is not an out-of-box failure.Based on the results of the investigation, no additional actions are needed.The instructions for use were found adequate and state the following: "fill reservoir 1) fill the reservoir with sterile water only.2) four liters of water will be required to fill the reservoir at initial installation.3) add one vial of arctic sun® temperature management system cleaning solution to the sterile water.4) from the patient therapy selection screen, press either the normothermia or hypothermia button, under the new patient heading.5) from the hypothermia or normothermia therapy screen, press the fill reservoir button.6) the fill reservoir screen will appear.Follow the directions on the screen.To replenish the internal cleaning solution: 1) drain the reservoir.¿ turn control module power off.¿ attach the drain line to the two drain ports on the back of the control module.Place the end of the drain line into a container.The water will passively drain into the container.2) refill the reservoir.¿ from the hypothermia therapy screen or the normothermia therapy screen, press the fill reservoir button.¿ the fill reservoir screen will appear.Follow the directions on the screen.¿ add one vial of arctic sun® temperature management system cleaning solution to the first bottle of sterile water.¿ the filling process will automatically stop when the reservoir is full.Continue to replace the bottles of sterile water until the filling process stops.¿ when the fill reservoir process is complete, the screen will close." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.H3 other text : the actual/suspected device was inspected.
