Maintenance
5. Remove any dirt or dust that is accumulated in the evacuator
valve installed to cover.
6. Direct dry compressed air (less than 0.69 MPa (7 kgf/cm²) to
the outer element from inside along its folds, then direct it
from outside along its folds and again from inside.
Remove one seal from the element whenever the ele-
ment has been cleaned.
Replace the outer element which has been cleaned 5
times repeatedly or used throughout a year. Replace the
inner element at the same time.
Replace both inner and outer elements when the monitor
lamp (H) lights up soon after installing the cleaned outer
element even though it has not been cleaned 5 times.
When replacing the element, new stick-on-seal (A) is
packed in the same box as the element. Stick the seal in
the position.
7. Remove the cloth or tape cover installed in Step 3.
8. If small holes or thin cracks are found on the element when it
is checked by shining a light through it after cleaning,
replace the element.
NOTE
When cleaning the element, do not hit or beat it against any-
thing.
Do not use an element whose folds or gasket or seal are
damaged.
