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.
