3.Using tweezers, forceps, or similar tool, remove any insert already in place.

4.Inspect the new insert to be installed: For a split mode insert, the end with the mixing chamber and packing is inserted first into the inlet.

5.Place a graphite or silicone O•ringon the insert, about 2 to 3 mm from its top end.

6.Install the insert, pressing it straight down, as far as possible, into the inlet.

Caution Do not add any seal either at the bottom of the inlet or at the bottom of the insert; to do so will damage the inlet and/or shatter the insert.

7.Replace the insert retainer nut, tightening it to firm finger•tightness to form a leak•freeseal. Do not overtighten.
