STAINLESS STEEL BAFFLE FILTERS

About Your New Filters

Stainless Steel Baffle 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 after being cleaned or going through the dishwasher.

How do Baffle 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.

PRE-INSTALLATION PROCEDURES

• Please read the instructions carefully. Unpack the Range Hood and check that 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.

•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.

Plug the Unit in and Test all Functions Before Installing.
