FILTER UNPACKING, INSTALLATION, STORAGE AND OPERATION
Unpacking
• Before removing the filter from the carton, carefully read the removal and handling instructions
printed on the outside of the carton.
• AAF Flanders Cleanroom filters may come packaged in suitcase-style cardboard sleeves. If
so, simply reach into the box and grab the handles pre-punched within the insert.
• If the filter is in a cardboard liner, the filter must be oriented such that the open ends of
the liner are facing outward (i.e. to your left and right rather than upward). Carefully cut the
packing tape that holds the filter in the liner. Always check for torn or deflected liner edges. If
any are found, straighten or flatten such edges prior to liner removal in order to prevent media
damage.
• One person should carefully hold the plastic bag(s) while the other person carefully pulls the
liner, sliding it away from the filter.
• Panel filters will be single- or double-bagged (depending on customer requirements) with
snug-fitting cardboard liners. Ducted filters will be single or double bagged and packed in
reinforced cartons.
• The filter should now be handled with extreme care to avoid contact with the media and/or
face screen.
• While the bag is still present, carry the filter by grabbing the bag. Be careful to keep the filter
away from your body and any objects in your path.
– If the bag is not present, always handle filter from the frame, avoiding contact with the
media and/or face screen.
• Remove the bag carefully. Avoid hand and finger contact with the filter media.
• Additional precautions for gel seal filters:
– Care is taken at the factory to prevent the bag from contacting the gel. Be very careful
when unpacking gel seal filters to remove the bag slowly and carefully.
– If the bag comes in contact with the gel, pull the bag off the gel slowly. Quick removal
of the bag may cause damage to the gel and possible separation of gel from the gel
channel.
Installation of Gel Seal Filters
• Carefully lift the filter into place, inserting it into the housing and taking care to make certain
the knife edge is properly seated into the fluid gel seal. Note: Setting filters properly requires
two (2) people.
• Rotate each of the filter retainers into place, one (1) in each corner, and hand-tighten the
hex nuts.
• Install the grille using the acorn nuts.
