Steps on How to Replace See Through Filter Window using O-Ring Kit:

1. Before you start you should have the following: Replacement See Through Polycarbonate Window, Replacement O-Ring Kit, Non-Chlorinated Break Clean, Paper Towels, Vaseline or any light weight Oil, Pint size Paint Can or a Roll of Duct Tape or Electrical Tape.
2. Remove the old window from the housing by taking the filter top housing apart from the filter base, turning it over and removing the eight small Allen head bolts that hold the retainer in place. Take aluminum Retainer out. The old window can then be pushed out from the top side of the filter housing using your fingers. This might take some force due to the O-Rings that seal it in place. Remove the two O-Rings stalled in the filter top for inspection.
3. Clean aluminum surfaces with Non-Chlorinated Break Clean and inspect for any possible visual damage.
4. Next Lubricate all O-Rings and Install the Largest O-Ring in to the Retainer Groove, Install the Medium size O-Ring into the Filter Housing Groove, and the Smallest O-Ring install into the Replacement Window Groove. It is recommended to place the window on a similar size apparatus to lift it off of your working surface. Suggest a pint size paint can for either the four or 6 inch. You could also use two rolls of electrical black tape stacked for the 4 inch and / or a roll of duct tape for the 6 inch. **Make sure to put a paper towel over anything used to lift the window off the table to make sure window stays clean.
5. Have the replacement Window sitting with O-Ring stalled into the Groove facing up on the apparatus, lifting it above the work surface. Then take the Filter Top with those O-Rings installed already and turn it over like you were looking down through it. Press the housing down squarely onto the new window, you should hear a pop noise when it is fully installed. Warning ** It would be very difficult to push the window in from behind only using your fingers **.
6. After the window is reinstalled, put the retainer back in its groove of the filter housing, reinstall and tighten the retainer mounting bolts, and reassemble filter top to the base.
