filter manufacturer to your job site. Remove all packing material, lay them flat and stack
them out of the way of the filtered hood, but near it. Do not throw away any packaging
until all filters are installed and operating correctly. Ensure you have a cap for every
filtered unpacked.
Note:
There are caps located on the electrical junctions of each filter. Collect all of
these and place back on the junctions of the filters if they come off during unpacking.
These are important for the protection of the filters and should be kept track of. If not
found on the filter, check in the box labeled on Figure 8-13 and place back as shown.
Step 4
Starting with filtration column 1, to access the old primary filter, the secondary filter and
fan box must be removed. Once these are removed, the old primary filter is the only unit
left on the base frame of the column. Mark the remaining used primary filter with a note
like “Used” with the tape and marker.
The fan and secondary filters will eventually be going back on the filtration column so
lay them flat and stack them out of the way.
Step 5
Remove the old primary filter you just labeled as “used”. This filter will be disposed of.
Consult local regulations and laws for disposal of hazardous waste.
Step 6
The old secondary filter that was
removed and stacked near the
substructure will now become the
primary filter. Label this filter with a
“P” over the existing “S” with the tape
and marker (as shown in Figure 8-15)
and stack back in the column it
originally came from. The new label
should be easy to read as the primary
SECONDARY FILTER.
