RECIRCULATION INSTRUCTIONS
RECIRCULATING INSTALLATIONS
For recirculating installations, Charcoal Filters are necessary. Remove all grease filters
and set aside. Attach one charcoal filter to each end of the blower. Each charcoal filter
attaches to the grid on the side of the blower. Rotate the filter clockwise to install and
counterclockwise to remove (FIGURE 3C). Replace all grease filters.
There are 2 ways to recirculate the Ostro:
1) Use the Ductless Recirculating Kit
(sold separately)
, refer to installation instructions
inside the Recirculating Kit which includes charcoal filters.
DUCTGRT30" - (30")

2) Duct work must be installed to exhaust the rangehood back into the kitchen, either at
the top of the cabinet (FIGURE 3A) or at the face or side of the soffit (FIGURE 3B). Install
at least 15" of metal duct (fig.3A and 3B) at the air exit. Run the duct vertically and se
-
cure it at the opening cut out at the top or side of the cabinet or soffit. Installation of metal
grill is recommended. This duct work must not terminate into a dead air space. FILTER1
