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:www.cosmoappliances.com

• 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.

IMPORTANT:
Plug the Unit in and Test all Functions Before Installing.

INSTALLATION INSTRUCTIONS

CAUTION: HOOD MAY HAVE VERY SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES WHENEVER IT IS NECESSARY TO REMOVE ANY PARTS FOR INSTALLING, CLEANING OR SERVICING.
Step 1:
Connect the Duct into the Damper (duct not included with ductless models)

  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  crewdriver. (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).

Step 3:
Connect installed duct to existing duct work. For best performance avoid steep angles in duct work (duct not included with ductless models). Ductless Installation:
Vent duct through cabinet and attach grate on top of cabinet (sold separately).
