Visual inspection of the mixer and flowmeters found that both of the flowmeters were broken at the top.The mixer could not be tested with the customer's returned flowmeters.The customer was contacted and inquired if the unit was damaged before the unit was shipped, the customer reported there was no damage before shipping.The broken flowmeters were due to customer not providing adequate packaging to ensure the mixer would not be damaged during shipping.The overhaul label is missing on the mixer.Qe tested the mixer with a known good flowmeter and it was found that the output would not go above 21.2%.The f102 knob was loose and rubbing on the mixer body and only one set screw was in the knob.At this time there is no evidence that a manufacturing non-conformity contributed to the reported complaint, and the last overhaul of the mixer found no non-conformities and the mixer passed all functional testing.User manual instructions for use were reviewed and determined to provide adequate instructions and warnings for the safe and effective use of the device.Therefore, no corrective or preventative actions are necessary.All complaints are trended and reviewed by management on a monthly basis.As part of this monthly review, any excursion above the control limits for this failure mode will be assessed, documented and acted upon as warranted.
