2. The “L” bracket can removed to form a 10”x 24” drop opening. See Figure 6.
3. If the cold air drop is less than 24 inches deep an angle bracket can be field fabricated and installed to reduce the drop width.
See Figure 7.
4. The cold air return can be moved into position over the top of the air cleaner (Figure 8) or transition pieces field fabricated
(Figure 9).
5. Four tabs are located on the outlet side of the air cleaner. These tabs can be bent into the cold air return opening on the HVAC
equipment to hold the air cleaner in position during installation. See Figure 10.
