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 pre-punched handles within the insert.
• If the filter is in a cardboard liner, the filter must be oriented so 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 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 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 by the frame, avoiding contact with the media and/
or face screen.
• Remove the bag carefully. Avoid bringing hands and fingers into 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 away from the gel seal.
- 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
• Carefully lift the filter into place and using the integral filter alignment tabs, insert into the housing,
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 four (4) filter retainers, one (1) in each corner, into place and hand-tighten the hex
nuts.
• Install the grille using the four (4) acorn nuts or ¼-turn fasteners with the hinged grille option.
Storage
• Location: Storage should be indoors, (under roof and enclosed) and absolutely protected from
moisture.
• It is strongly recommended that the storage space be climate-controlled.
- Temperature Limits: Maximum temperatures of 250°F (121°C) intermittent, and 100°F (38°C)
steady state. Minimum temperature is 32°F (0°C).
