(1) See “Filter Media” section for selection of proper media for your filtration application.

(2) Caution should always be used in sizing filters! Since these filters do not remove sediment, it is advisable to install a Line Strainer (model SS 20100) ahead of the inlet to prevent plugging of the distributor tube. Use of a flow control in the Service Line is highly recommended. Consult the factory or your field sales person with questions.
