    GROUNDING INSTRUCTIONS
    This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
    Consult a qualified electrician if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.
    Do not use an extension cord. If the power supply cord is too short, have a qualified electrician install an outlet near the appliance.TO REDUCE THE RISK OF INJURY TO PERSONS, IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:
  •  SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediate-ly, EVACUATE AND CALL THE FIRE DEPARTMENT.
  •  NEVER PICK UP A FLAMING PAN – You may be burned.
  •  DO NOT USE WATER, including wet dishcloths or towels –

  •  The fire is small and contained in the area where it started.
  •  The fire department is being called.
  •  You can fight the fire with your back to an exit
  • Always leave safety grills and filters in place. Without these components, operating blowers could catch onto hair, fingers and loose clothing.
  • The manufacturer declines all responsibility in the event of failure to observe the instructions given here for installation, maintenance, and suitable use of the product. The manufacturer further declines all responsibility for injury due to negligence and the warranty of the unit automatically expires due to improper maintenance.

  •  Clean ventilating fans frequently. Grease should not be

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.

PARTS NEEDED

PRE-INSTALLATION REQUIREMENTS

  •  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 from occurring during installation.
  • The manufacturer shall not be held liable for the 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 the 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, the 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 a straight duct plus duct fitting must be 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

CAUTION: THE 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:

STEP:2

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 securing it to the wall to avoid a gap. Before starting, locate the included template to line up at your install location.
  •  Find the keyholes 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.
  •  Drill (4) 5/16″ (8mm) holes into the 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.
  •  Drill an electrical access hole into the cabinet above as shown on the template.
  •  Locate the top keyholes and line up Range Hood with protruding wall screws while also lining up to holes above and inserting wood screws through top holes and fastening 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)
  •  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 the electrical access hole.
