2. Carefully clean the inside of the housing, the cover and sealing faces with a damp cloth.

■ Use dry compressed air (≤ 72 psig!) at an angle to blow dust from the filter element from
inside to outside until no further dust develops.
■ The blast pipe must be long enough to reach the bottom of the element.
■ The tip of the blast pipe should not be allowed to touch the element.
■ Clean sealing faces.
4. Inspect the element carefully for any damage.
Replace any damaged filter element.
