Investigation findings: the lot number reported by the customer is for a different part number (400c00) than the one reported (t736ns).The 400c00 is just the cold therapy unit alone and does not come with a cold therapy blanket.Part number t736ns is the same cold therapy unit and it does come with a therapy blanket.A review of the work order showed no discrepancies that would have contributed to the reported issue.The complaint sample was received.A 5036 blanket was returned with the unit (400c00).The blanket was not attached to the unit hoses.Visual inspection of the blanket showed that the o-rings were on both of the blanket "legs".This is noted because missing o-rings could be a possible leak source.It also showed that the lot number label was worn off the blanket.Therefore, the blanket lot number is unknown and its work order cannot be reviewed.Testing was performed by putting ice and water inside it, attaching the blanket to the unit hoses, turning the unit on and allowing it to run.The unit ran for 22 minutes and worked correctly and leaking was not seen from anywhere on the unit or blanket.He customer's report could not be verified.Root cause: undetermined due to leaking was not seen when testing was performed.Corrections: a replacement was issued.Corrective action: no corrective action taken due to the customer's report was not verified.Preventive action: no preventative action taken due to the customer's report was not verified.No further information is available at this time.We will provide follow up report if additional information becomes available.
