the operator's health, the personnel in
charge for the maintenance must wear
appropriate protective clothing.
Perform the main filter replacement outdoors, if
possible.
The old filter must be disposed of in a special plastic
bag.

away the filter if it is soiled with toxic dust or harmful
materials. The filter must be handed over to the
authorities in possession of the necessary permission
to dispose of such waste. When replacing the main filter

WARNING!
Filter replacement is a serious matter. The
filter must be replaced with one of
identical characteristics, category and

filter you intend to replace, and proceed as follows:
(Fig. 8). Disassemble the old filter retainer and the
retaining ring, and mount them on to the new filter.
