Ductless recirculation is intended for applications where an exhaust duct work is not possible to be installed.
When converted, the hood functions as a recirculating hood rather than an exhaust hood. Fumes and exhaust
from cooking are drawn and fi ltered by a set of optional charcoal fi lters. The air is then purifi ed and re-
circulated back within the home.
We recommend to ALWAYS exhaust air outside of the home by employing existing or installing new duct
work, if possible. The hood is most effective and effi cient as an exhaust hood. Only when the exhaust option
is not possible should you recourse to converting the hood into a recirculating hood.
When converted to be a recirculating hood, a set of charcoal fi lters are required on top of its standard
aluminum mesh fi lter set. Order according to its part number below. The standard aluminum mesh fi lters are
intended to capture residue from cooking and the optional charcoal fi lters help to purify fumes exhausted from
cooking for recirculation.

of air diverter plate should face left and right to direct air through the
louver holes located on the top duct cover. Run 8” ducting from top of
hood and secure to air diverter plate.
3. Remove aluminum mesh fi lters from hood. Install charcoal fi lter
brackets inside fi lter opening. Note: screws to secure charcoal fi lter
brackets are already pre-installed in the hood and must fi rst be
removed. Clip charcoal fi lters onto each charcoal fi lter bracket. (FIG.

5. Turn on charcoal fi lter change indicator on control panel. (Refer to
details on page 13.) The microprocessor in the controls will indicate
the need to change the charcoal fi lter after 120 hours of continuous
use. Order replacement charcoal fi lters per the list below.
Charcoal fi lters must be replaced after every 120 hours of use (or
approximately every 3 to 4 months based on an average of 1 - 2 hrs.
of daily cooking time).
