5.4 Maintaining the dust discharge

valve

Dust discharge valves should be checked

according to dust concentration in the sur-

roundings and preferably daily at heavy dust

occurence. Remove any dust deposits by

squeezing the valve (see Fig. 6). The valve

must be free and should not strike anything.

Replace damaged valves.

6. Storage of filter elements

Protect stored filter elements from

exposure to dust, moisture and dam-

age. Store vertically, preferably in their

original packaging.

It is practical to keep at least one replace-

ment element in stock for each filter element

required.
