Never operate the unit without the air filter element. Never use elements that
are damaged, ruptured or wet. Keep spare elements on hand to reduce
downtime. Store elements in a protected area free from damage, dirt and
moisture. Handle all parts with care.
Filter Element Inspection and Replacement:
1. Remove air cleaner cover and remove filter element.
2. Visually inspect housing inner tube against which the element makes a seal. Wipe dirt from outer
surface if necessary. Also visually inspect the matching o-ring seal that is bonded to the element for
defects and dirt, then wipe clean if necessary.
3. Visually inspect media. If flaws (e.g., tears of media, damage to sealing o-ring, etc.) are evident or if
the pressure loss has triggered the vacuum switch (activation level is 30 inches water gauge)
provided with the package instrumentation, replace the element. Cleansing the element with air or
water is not recommended, as media damage is very probable.
4. Replace element and cover and fasten cover to filter housing.
