Hi Bob, Yes if you have a Nautilus 48 then this is the correct DE grid assembly. If you don't see any reference to your square footage of 48 Sq. Ft. on the filter tank, then measure the grid height and if it measures approximately 24" tall then you have the 48.

I have a 1987 FNS 48 with a small pinky size hole in one of the eight filters. Is it time for replacing all the filters (they are 30 years old) or how do I fix the hole? Thx mike

A  Answered on 5/8/2019 by InyoPools Product Specialist Hector F.

At that age I would highly recommend replacing all of the grids or even the entire grid assembly.

I have a Purex Triton Nautilus FNS 48. Is this the correct grid assy? Thanks

A  Answered on 6/9/2016 by InyoPools Product Specialist Joe S.

Hello Guy, yes the 195086 will be the correct Pre-Assembled Drop in Grid Assembly for the FNS 48 Sq. Ft. DE Filter. Also do inspect the body oring as it is best to change it when you change the grids. O-ring, Tank (o-420) PART # 4600-5008 would be the replacement.

I had DE all over the pool floor. I needed to clean the grids for spring anyway. After removing the grid and inspecting the filters I saw the cracked manifold and a couple of grids poking through the filters. Instead of replacing pieces I decided to start over with a whole new assembly. After installing the new assembly I had forgotten about checking that the manifold extension was in place. Now everything is good.

Were these instructions helpful?
