Due to the design on your autoclave, Your Midmark M9 requires the a Dam Gasket. Follow the directions below for an easy installation

1. Place the Dam Gasket into the groove of the Door Gasket so that the Dam Gasket touches the Door Plate Studs


2. Align the slots located on the back side of the Dam Gasket (see Figure A for location of slots) with the Door Plate Studs.
   
   Then using a nutdriver, push against the front side of the Dam Gasket so that the Door Plate Studs protrude through the front side of the Dam Gasket (see Figure B). This will secure the Dam Gasket in place.

IMPORTANT: To ensure that the door will open/close properly, the Dam Gasket must lie flat against the Door Plate – there must be no gaps.
