ON (B)(6) 2014, IT WAS NOTED THAT 14 DEVICES WHICH HAD BEEN RETURNED FOR REPAIR CONTAINED DIAPHRAGMS WHICH HAD SIGNIFICANT TEARS IN THEM AFTER DEVICE LIFE OF LESS THAN 6 MONTHS. AT THE TIME OF QUALITY ASSURANCE AWARENESS ON (B)(6) 2014 PREVIOUS RETURNS WERE REVIEWED FURTHER TO DETERMINE IF ANY OTHER NEWER DEVICES HAD BEEN RETURNED WITH CONFIRMED DAMAGED DIAPHRAGMS.

INVESTIGATION IS ONGOING INTO CAUSE AND APPLICABLE CORRECTION.

Additional Manufacturer Narrative

DEVICE IS A VACUUM REGULATOR. THE DEVICE ACHIEVES ITS FUNCTION VIA A REGULATOR MODULE THAT IS EQUIPPED WITH A DIAPHRAGM. THE USER FILED A COMPLAINT THAT THE REGULATOR GAGE WAS JUMPY.
