inner sealing surface of the nut and cause leaks.

remain on the nut. Clean out any residue in the nut.

8. Using tweezers or forceps, place the smaller o-ring into

the nut. Place the filter disk on top and then lastly place

the larger o-ring into the nut.

NOTE: Do not touch the o-rings or the filter disk with your fingers.

9. Again use the 1/2 inch socket to place the nut onto the

fixed seal assembly. Ensure the nut is threaded properly

and then tighten it until it just seats against the

assembly.
