STAINLESS STEEL PERMANENT FILTERS
About Your New Filters Stainless Steel Permanent Filters do not need linings
or mesh inside of the filters and are completely constructed out of stainless
steel. The stainless steel construction allows them to be used again and again
after being cleaned or going through the dishwasher. How do Permanent Filters
work? They function by forcing the grease filled air to quickly and
continuously change direction as it passes through the filter. The grease is
unable to change direction as fast as the air carrying them, they end up
getting caught on the metal blades and then trapped into the filter tray.
These filters are both efficient and require less maintenance.
Additional Aluminum or Charcoal Filters can be purchased from:

all functions are working before installing.
· Ensure that the voltage (V) and the frequency (Hz) indicated on the sticker
match the voltage and frequency at the installation site.
· Check that the area behind the installation surface to be drilled is clear
of any electrical cables or pipes, etc.
· The stainless steel surfaces of the Range Hood are very easily damaged
during installation if scratched or bumped by tools. Please take care to
protect the surfaces during installation.
· Protect the cooktop surface below with cardboard, or the like, to prevent
damage occurring during installation.
· The manufacturer shall not be held liable for consumer’s failure to observe
and follow all pre-installation procedures and safety regulations.
· The vertical distance from the cooking surface to the bottom of the range
hood should be at least 24 in. to 36 in. for best performance.
· Determine if your installation will be top venting or back venting, and
ensure that the openings in the cabinet or wall are in the appropriate
locations and appropriate size.
· If this is a new installation, choose the venting method that suits your
needs. Cut out openings for the damper and for power access in the cabinet
bottom or exterior wall, depending on the installation method chosen. DUCTWORK
PLANNING
· These vent hoods are equipped for 8″ round ductwork. This hood may be vented
vertically through upper cabinet or ceiling. A duct transition piece is
supplied for vertical exhaust. You may use elbows (sold separately) to vent
horizontally through the rear wall (duct not included with ductless models).
· Determine the exact location of the vent hood. · Plan the route for venting
exhaust to the outdoors. · Use the shortest and straightest duct route
possible. For satisfactory
performance,duct run should not exceed 12.5 feet. equivalent length for any
duct configurations.
· Use metal ductwork only.
WALL FRAMING FOR ADEQUATE SUPPORT
These vent hoods are heavy. Adequate structural support must be provided. *
Actual length of straight duct plus duct fitting must equivalent. Equivalent
lengths of duct pieces are based on actual tests conducted by Evaluation
Engineering and reflect requirements for good venting performance with any
ventilation hood.

INSTALLATION INSTRUCTIONS
Top /Rear Mounted Installation
- Due to the weight of the unit, we recommend mounting the Range Hood to the bottom of the cabinet above first and then secure it to wall to avoid a gap. Before starting, locate the included template to line up at your install location. 1.) Find the key holes at the back and top of the Range Hood. Mark their locations at the installation location using the included templates (Wall / Bottom of Cabinet) with a pencil or marker. 2.) Drill (4) 5/16″ (8mm) holes into wall at each of the marked locations. Insert included drywall anchors into wall holes. Firmly tap them into place. Insert screws into anchors and leave 1/4″ out for Range Hood to hang on. 3.) Drill an electrical access hole into cabinet above as shown on template. 4.) Locate the top key holes and line up Range Hood with protruding wall screws while also lining up to holes above and insert wood screws through top holes and fasten the Range Hood to the bottom of the cabinet by tightening screws with a drill or screwdriver. (this step requires you to Lift and Hang at the same time / requires two people) 5.) Tighten up screws to secure the Range Hood to the wall once it is fastened to the cabinet. 6.) Run attached ducting through cabinet as required and electrical wires through electrical access hole (duct not included with ductless models).
