15.2 Replacing the Air Filter
To facilitate drying the instruments with the door of the chamber closed,
models EA are equipped with an air compressor and HEPA filter (0.2µm).
During the drying stage the compressor draws air through the HEPA filter
and forces the circulation of that air through the heated chamber to remove
moisture from the wrapped instruments. The filtration of the air is
performed by the bacteriological filter. Frequency of replacement will be
determined depending on the usage of the autoclave and the surrounding
environment.
The filter is mounted in an opening on the right sidewall of the autoclave
enclosure, this is to allow easy access for replacing it, (see picture below).
To replace the filter proceed as follows:
1. Remove the filter cover (2) by turning the cover counterclockwise
until it is released.
2. Remove the filter (5) from the filter cover by pulling the filter apart
from the filter cover
3. Cut the tie wrap (4) fixing the flexible tube (3) connecting the filter to
the copper pipe, and pull off the filter.
4. Replace the filter with a new one. Connect the filter (5) to the flexible
tube (3) and tighten it with a tie wrap (4).
5. Connect the filter to the filter cover by pressing the filter (5) into the
hole in the cover (1).
6. Insert the filter to its place inside the autoclave and reassemble the
filter cover by turning it a ¼ turn clockwise. Verify that the cover is
fastened well in its place.
