Step 2
Access the old pre-filter from the trap door under the bottom of the filtration column.
There are two clips at the front of the column. These clips may be fixed in place by two
screws. Remove and save the screws, then push on the clips and pull the trap door
down.
Step 3
From here, the trap door is down and the pre-filter is exposed. Remove the pre-filter
from the door.
Caution:
If the pre-filter is contaminated by hazardous particles intercepted in filtered
hood use, you must perform this with the ventilation turned on. Immediately after
removal of the trap door, pack the used pre-filters in the appropriate disposal container
while still inside the filtered hood.
