How to Assemble a Hayward DE4820 Filter Grid Assembly

Assembling a DE filter grid assembly can seem like a daunting task, but with the right guidance, it's easy and straightforward. In this article, we'll walk you through the step-by-step process of assembling your Hayward DE4820 filter grid assembly using the Right Side Up method.

Step 1: Prepare the Manifold

Before starting, make sure you have all the necessary parts and tools. Begin by putting the manifold on the ground, ensuring that the pipe inlet is over the notch-out opening on the base. If your filter has a top guide, use it to line up the grids before placing the manifold.

Step 2: Install the Grids

Once all grids are installed, verify that they are seated in their clips and none have slipped out. Start by placing the grids in their designated spots, making sure the partial grid goes into the correct spot. There is one circle labeled 'small grid' where the partial grid should go.

Step 3: Position the Grids

The base has a built-in guide to show you where each grid lines up. The rods are wobbly and can be removed by sliding them out from the base. Take your time to ensure that each grid is properly seated in its clip, making sure they don't slip out.

Step 4: Final Check

After all grids are installed, perform a final check to verify that none have slipped out of their clips. Make sure the partial grid is correctly positioned and the rods are securely attached to the base.

Alternative Assembly Method - Upside Down

If your metal rods are not fixed to the base, you can use the upside-down method instead. This method involves placing the top manifold on the ground and building the assembly backwards. However, for most DE filters, the Right Side Up method is recommended.

Assembling a Hayward DE4820 filter grid assembly requires attention to detail and patience. By following these steps and using the Right Side Up method, you'll have your filter up and running in no time.
