Step 5
If you are installing the HEPA filters for the first time, ignore this and move to the next
step.
Remove the old HEPA filter
s you just labeled as “Used”. This filter will no longer be in
use so it must be disposed of correctly. Consult local regulations and laws for disposal
of hazardous waste. Do NOT dispose of the junction frame shown in Figure 8-20 & 8-
21. The frame will be used again later.
Step 6
The new HEPA filters will now be placed in the column.
If a 2C1P model:
1. Place the junction frame on top of the secondary filter. See Figure 8-21.
2. Then lower the HEPA filter on the frame.
3. Verify the connection is secure and all sides are sealed.
If a 1P2C model:
1. Lower the HEPA filter on the base frame.
2. Place the junction frame on the top of the HEPA filter.
3. Verify the connection is secure and all sides are sealed.
If replacing, make sure to stack the filters and fan boxes in the column they originally
came from. Use the tape and a marker to label the HEPA filter with the number of the
column it is in.
Note: The junction frame always goes between the HEPA and a Neutrodine filter in
2C1P and 1P2C models for containment safety.
Step 7
If making the 2C1P configuration,
place cap on the HEPA filter’s electrical plug and
move to the next step.
If making the 1P2C configuration, locate the
Neutrodine filters and fan box previously
removed from the column. Replace them in
the following order bottom to top (shown in
Figure 8-20):
1. Junction frame
2. Primary filter
3. Fan box
4. Secondary filter
Ensure the filters and fan boxes are all in the
correct column and that the primary filter is
