The following safety precautions must be followed by all personnel handling the
equipment and filtration columns:

It is recommended you follow all of your existing lab safety protocols as they
apply to this procedure

2 persons required for this procedure

Read instructions carefully before attempting

Do NOT have fans running during this process
Step 1
Turn the filtered hood completely off and disconnect from external power. Remove the
front panel (see
Section 8: Front Panel Removal ) of the filtered hood and place nearby
but out of the way. This will expose the filtration column technology you will be working
with.
Step 2
Identify the filtered hood you have and order the correct filters but in type and quantity
for replacing. Determine your model number which is a M1 (3 FT), M2 (4 FT), M3 (5
FT), M4 (6 FT), or M5 (8 FT). These numbers are based on how many stacks of
technology that you have on top of your filtered hood from left to right and the filtered
hood width.

Look at your filtered hood and count the stacks of technology from left to right

You will have 1, 2, 3, 4, or 5 stacks for 3 FT, 4 FT, 5 FT, 6 FT, and 8 FT filtered
hoods.

Match that number to M1, M2, M3, M4, or M5.

This information will help you follow this procedure when it applies to your model
M1, M2, M3, M4, M5.
Step 3
To unpack the new filters, carefully remove from the packaging. The HEPA filters are
shipped directly from the 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 HEPA filters are installed and operating correctly.
Step 4
If installing the HEPAs for the first time ignore this step.
Identify the technology configuration of your filtered hood as either 1P2C or 2C1P. See
Figure 8-20 & 8-21 for help identifying the configuration of the filtered hood.

If a 2C1P model, no other filtration technology must be removed. The top unit on
the column
is the HEPA filter, label it “Used”.

If a 1P2C model, remove the secondary filter, fan box and primary filter to access
the HEPA. Stack them carefully. Label
the HEPA filter “Used”.
