Replacing Filters
Replace the filters in the same ordered stack, and in the same airflow
direction, as the old filters.
5.
Install the filter(s)
(gasket side down, airflow arrows up, filter labels in front)
It is good
practice to lift the filter(s) by the grab handles as you slide them over the top of the hood to
avoid damage to the bottom filter gasket. Ensure top filter aligns with properly placed
bottom filter on all sides.
6.
Once the filter(s) are in place inspect the mating of the gaskets to the surface. Ensure no
cables are caught and no gasket damage exist.
7.
Hand tighten the four knobs at the top of the fan unit in an even manner in the sequence
shown until filter(s) are sufficiently sealed.
(NOTE: Do not tighten a single knob more than one turn at a time).
