1 Insert supplied screwdriver down into each of the 3 top holes and unscrew the bolts housed within. Note: Once fully unscrewed the bolts will remain under the stainless steel top.

2 Pry apart the upper and lower portions to access the underside of the upper housing. Be patient prying apart as the ViscoRing™ can become tacky and slow to separate. The bottom portion can be partially unthreaded to increase prying leverage.

3 Use the supplied screwdriver to unscrew the 3 screws holding the stainless steel top center portion to the upper housing.

4 Remove the standard top section by pushing it out from the bottom center of the housing.

5 Insert and press down to fully seat the diamond version of the top section into the opening on the top of the upper housing.

6 Use the supplied screwdriver to screw back in the 3 screws holding the top center portion to the upper housing.

7 Align the top holes on the upper portion with the thread holes on top of the lower portion. Press the upper portion down over the top of the lower portion. Insert the screwdriver into the top holes and tighten the bolts housed within. If the bolts still do not align with their holes, remove the upper portion and try again.
