i guess its the DE3620....had to take an old grid to the store to match.

Hey there..new to the forum. I have a Hayward DE filter for my saltwater pool. The filter is probably about 13-14 years old? My question is, I do not know what size filter I have. I believe I need to change out some of the grids and the filter is not marked as to which type it is, ie DE2420, DE3620 etc etc. its approximately 34 inches tall from the cement base its on to the top of the filter holding the pressure gauge. Unfortunately, when installed they did not mark the label on the filter as to its model number. There also is no serial number marked on it either. any help would be appreciated.
