Instructions for Replacing the MultiHazard Glove Box HEPA

Filters

Note: A qualified service technician must preform this operation under the supervision of
the Safety Officer. The Technician must use appropriate Personal Protective Equipment.

(Always work from the dirty side of the filter towards the clean.)

1. Turn the blower on. Increase speed to maximum.
(Fig 1)

2. Allow Glove Box to vent thoroughly to purge air
borne contaminants. (Approx. 30 minutes)

3. As an option to seal any contaminants to surface
areas, a clear acrylic may be sprayed (spraying for
approximately 10 to 15 seconds) into the exhaust
port within the Glove Box main chamber. This
seals any physical contaminants to the filter media.
Allow the acrylic to dry, 5 minutes.

4. Loosen the upper clamp from around the inlet side of
the exhaust/HEPA filter using a straight edge
screwdriver. (Fig 2)

the HEPA filter. (Fig 3)
