Cleaning
1. Paper element: Tap the element lightly several times on a hard surface to
remove excess dirt, or blow compressed air [not exceeding 270 kPa (30
psi)] through the filter element from the inside out. Never try to brush the dirt
off; brushing will force dirt into the paper fibers. Replace the paper element
if it is excessively dirty or dam-
aged.
2. Foam element cleaning: Wash
the element in a solution of house-
hold detergent and warm water,
then rinse thoroughly, or wash in
nonflammable solvent.
