Assembly Of Vertical DE Filter Grids - What A Pain!

by Ted
(Virginia)

I have a PAC-FAB Nautilus FNS Filter (48 sq ft) and recently needed to disassemble the grid assembly to clean it...it consists of 7 standard grids and one shorter one.

I have not been able to put it back together...ugh. I found one set of directions that says: "Starting with the SMALL GRID element, place the element on the bottom spreader in the position marked 'SMALL GRID' using the 'foot print' pattern as a guide for proper location --- but there is no such marking on my bottom spreader.

Any advice, diagrams or pictures of how this is put together would be greatly appreciated.




Thanks for the question Ted

I respect DE pool filters for their cleaning properties, BUT, I know from first-hand knowledge that they can be a real pain to get back together.

Normally pool owners will have an issue like yours; getting the grids back into the manifold or manifold retainer. Trying to get the grids lined up without falling over can be a test of patience.

Unfortunately there's really no easy way to exactly describe, in detail, what you need to do. There are many variables when it comes to putting a DE filter back together. It is something that you need to watch a few times to get the hang of it, or have a really good diagram on hand.

When I was doing pools in Arizona, I helped with about 10 of them before I attempted to clean and replace the DE grids by myself.

I did find a couple of sites that might help you:

www.troubleshooters.com/pool/de_filter_cleaning.htm

www.mypool.com/Help_Files/Parts_Diagrams/PacFabFNS.htm

Hope this helps your situation and have a great rest of the Summer

Robert

Robert, just came across your site. I have an American products 48 sq. ft. DE filter.

When I tried to reassemble it, I could not do it by myself.

Later I finally tried to do it with top down/bottom up and was successful.
