4. Place both arms in the rear gloves of the bag, and carefully draw the
HEPA filter out of the glove box. Rest the HEPA filter on the floor,
table or cart. Remove arms from bag gloves.
5. Create two seals between the glove box housing and the old HEPA
filter. Seals can be heat sealed or sealed with tie wraps. Cut off the
bag between the two seals and leave the bag stub on the access port to
the glove box.
6. Place the new HEPA filter in another new bag. Then place the new
bag with the new HEPA filter over the old bag stub and onto the
glove box filter housing.
7. Carefully remove the old bag from the filter housing using the single
glove near the access port. Draw the old bag and stub into the single
glove and turn the glove inside out. Double seal this glove on the
contaminated bag stub inside. Remove the bag and dispose of
properly.
8. Carefully install the new HEPA filter and uniformly tighten the six
filter nuts until the HEPA filter gasket is compressed 50%.
9. Turn the glove box ON and proceed to the HEPA Filter Leak Test in
