hinge and lowering the pins into the hinges. If the cover
is properly attached, it can hang below the F90.

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 2-1/2
turns. Do not remove screw.
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.
