ADJUSTMENTS
Louver Adjustment
CAUTION
Do not operate air cleaner without the louvers installed.
The F90 plastic louvers can be repositioned to vary the airflow pattern. Three positions are available. Position 3 directs airflow along the ceiling. Positions 2 and 1 direct airflow downward. Use position 2 or 1 if ceiling staining is a problem or if beams or other obstacles disrupt airflow.
Louvers are shipped in position 1. Louvers can be adjusted as follows:
1. Loosen screw by turning counterclockwise
2. Push louvers up to disengage bottom tabs, and pull bottom of the louvers out slightly to desired position.
3. Retighten the screw. Assure that the tabs on the bottom of the louvers are positively engaged with the F90 frame.
