3. Place cabinet in ductwork. Holes are provided to
attach cabinet to ductwork or equipment. If
adjoining ductwork is flanged, install the screws so
that screw heads are inside cabinet. This will help
prevent damage to prefilter and carbon filters
during removal for cleaning. NEVER put screws or
rivets into the removable power box.
When the air duct does not fit Air Cleaner opening,
a gradual transition is recommended to reduce air
turbulence through Air Cleaner and to increase its
efficiency. There should not be more than 20º of
expansion used on each side of transition fitting.
Do not reduce ductwork to a smaller Air Cleaner or
it will increase velocity of airflow.
4. If Air Cleaner is installed adjacent to an elbow or
angle fitting, turning vanes are recommended to
improve air distribution across the collecting cells.
5. After Air Cleaner has been secured, seal seams
airtight with duct tape or caulking to prevent dust
from entering the system.
6. Replace prefilters, collecting cells and carbon
filters. Make sure arrow on cell is pointing towards
the fan. The cell handle may need to be
repositioned if the airflow is in a different direction
than the left to right set up. The handle should face
the door. Close access door.

Allow 24 in (600 mm) clearance for cleaning air cleaner. Allow 6 in. (150 mm) clearance for power box removal.
