Cleaning Filter Elements

For a more thorough cleaning of the individual elements, perform the following steps:

1.Cleaning with water:

a. Using a garden hose, thoroughly flush off all contaminated diatomite from the filter element surfaces.

2.Cleaning with muriatic acid:

Cleaning Filter Elements WARNING — Working with muriatic acid can be dangerous. When cleaning elements always wear rubber gloves

and eye protection. Add acid to water, do not add water to acid. Splashing or spilling acid can cause severe personal injury and/or property damage.

a.A stiffening of the fabric caused by mineral deposits is usually referred to as "liming up". It usually is due to deposits of either magnesium or calcium or both. Removal of these deposits may be accomplished by soaking the filter elements in six (6) parts water to one (1) part hydrochloric acid (muriatic acid).

b.Wear rubber gloves and eye protection when mixing the solution, and handling or rinsing the filter elements.

c.Soak for at least four (4) hours in a plastic tub or pail.

d.Rinse filter elements thoroughly in tap water.
