Changing the filters

Do not ever attempt to change the
filters during an NBC event. Wait
until it is over and you have
credible indications that the outside
atmosphere is safe to breath.
Once the event has been cleared
and confirmed that it was nuclear,
biological, or chemical, all of the
filters should be changed to remove
the toxins trapped inside them.
This includes the pre-filters, the
HEPA filter, and the carbon
adsorber.
Filters that are known or suspected
of being used during an NBC event
are considered hazardous waste
and should be disposed of
appropriately.
This disposal should be done in
accordance with all laws and
regulations governing hazardous
waste disposal. Do not attempt to
bury or incinerate used filters.
Groundwater leachate (liquid that
contains toxic chemicals) is very
hazardous and smoke or fumes
that are given off during burning
may be hazardous if allowed to
come into contact with the skin or
inhaled into the lungs.
To change the filters:
1.
Slip the red shipping caps on all of the ports, then turn the Safe Cell off.
2.
Remove the Safe Cell from the wall mount bracket by removing the star nuts.
3.
Take the complete Safe Cell outside the shelter and away from people and buildings.
4.

5.
Remove the 2 side plates
6.
Remove the top end bell
7.
Remove all of the filter elements
8.
Wipe clean and inspect the end bell interiors and the sealing surfaces on them
9.
Assemble the new filters in the Safe Cell (from bottom to top: the coarse pre-filter, the
fine pre-filter, the HEPA filter, and the carbon adsorber)
10.
Assemble the side plates and reinstall the 8 clamping bolts and nuts
11.
Take the Safe Cell back into the shelter, mount it on the
bracket, and attach the air intake hose
Replacement filters should be obtained from American Safe Room.
Alternate sourcing of filters is not recommended and removes American Safe Room
from liability resulting from inadequate performance by third-party filters.
