Do not damage the surface.
5.5. Filter unit
General
Sufficient air filtering and regular filter changes will reduce the dust
content in the air and prevent contamination of the equipment and
ducting system. Excessive filter service usage degrades the air
quality due to odours. Moisture penetration of the filter must be
avoided for hygienic reasons.
The filter should be checked at regular intervals and replaced as
necessary, dependent upon operating conditions. As a rule, if the
manufacturer's prescribed pressure differential is exceeded, the
filter should be replaced. When replacing the filter, the leak-
tightness around the filter adapter frame should be checked.
Damage or pressure marks on the filter surface are to be avoided
without fail, as otherwise the filter can rip during operation.

Filter resistance can be determined by means of a differential
pressure measurement using an inclined-tube manometer, or
electronic manometer.
The pocket type filter is not reclaimable. When the final resistance is
reached, the pocket type filter must be replaced with a new one.
Replacement of individual filter elements is allowable only in case of
damage to the individual elements, and as long as the previous
replacement was no longer than 6 months back.
When replacing the filter insert, a breathing protection mask with a
P3 filter should be worn and the local environmental protection
regulations observed.
Dust laden filters pose an increased health risk.
Filters must be stored in a dry, dust-free environment. A filter
should no longer be used upon expiration of its minimum shelf life.
Commissioning
Filter inserts are secured in the mounting frame with tensioned
fastening clamps. Filter inserts elements must not be pinched or
clamped. Check the filter insert for an air-tight seat in the mounting
frame.
Prior to commissioning, the filter units must be checked for
damage.
Maintenance
Check pocket type filters and frames for contaminants and
-
damage
Check filter seat for leak-tightness and visually inspect for
-
damage
Replace filter inserts with noticeable dust contamination,
-
odours or leakage.
Replace filter inserts when the recommended final resistance is
-
reached
Replace, at the latest, the 1st filter level after 12 months and
-
the 2nd filter level after 24 months.
