will these fit any filter

Hi. These grids will not fit any filter. You will need to locate your filter model to confirm the correct size replacement grid.

How do I know which replacement grids I should order?

A  Answered on 12/18/2012 by InyoPools Product Specialist Patrick P.

Typically, the filter label will contain the filter model and square footage of your grids. If the information on the label can not be read, you can measure the length (top to bottom) of the grid and multiply by 2 to get the square footage. For example: A 12" grid length would mean that the square footage is 24.

This is the same procedure for installing the other 7 grids, I'm repeating it here for completeness.

After opening the air relief valve to remove the pressure from the tank, I removed the tank cover. Then I took the grid assembly out of the tank. I disassembled the unit by removing the 5/16" locking nut from the top while holding the 7/16" nut at the bottom with an adjustable wrench. After disposing the old grids and hosing down the residual de from the other parts, with the aid of a video from YouTube, I reassembled the grids in the upright position using a grid guide costing $15 from a local retail store that really made it easy to attach the manifold. Reinstall the locking nut and place the complete grid assembly back into the tank. The whole process was fairly straight forward but took some patience. Most important thing is to replace each grid in the proper order. Total time spent about two hours.

Were these instructions helpful?
