Element Replacement Procedure
Series ZFC

1. Stop operation and reduce the filter's internal pressure to atmosphere.

2. Turn cover "A" counterclockwise until it stops, (approx. 45°.)

3. Pull cover "A" out of the case and remove the element. Remove dust and other debris remaining inside the case by blowing it out with air, etc. (Also confirm that the O-ring is not damaged.)

4. Install a new element on cover "A" and insert it into the case.

5. After aligning the projections (2 places) on cover "A" with the grooves in the case, push cover "A" in and turn it clockwise until it stops, (approx. 45.) (Confirm that the projections on cover "A" can be seen completely through the windows in the case.)

6. Restart operation.
