Hayward de480s filter

when changing the filters for the Hayward 480s micro filter, where would I place the 1 small filter ?

there are no markings to show me where it goes. Can any one out there in the INYO world help me solve this puzzle ?

I Thank you in advance

We have a video that details how to reassemble the grids. It was a Hayward Pro-Grid filter but the grids are exactly the same as the Micro. Let me know if you have any questions.
