STAINLESS STEEL BAFFLE 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.

See Page 16 for instructions on Installation Filters.

WARNING

⚠️ 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.

⚠️ IMPROPER GROUNDING CAN RESULT IN A RISK OF ELECTRIC SHOCK.

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.

WARNING

⚠️ TO REDUCE THE RISK OF INJURY TO PERSONS, IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:

• A. SMOTHER FLAMES with a close fitting lid, cookie sheet, or other metal tray, then turn off the gas burner or the electric element. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.
• B. NEVER PICK UP A FLAMING PAN - you may be burned. DO NOT USE WATER including wet dishcloths or towels - a violent steam explosion will result.

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.

WARNING

⚠️ To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Hood With Any External Solid State Speed Control Device.

WARNING

⚠️ Unplug or disconnect the appliance from the power supply before servicing.

INSTALLATION REQUIREMENTS

1. Do not install the range hood near open doors and windows to avoid reduced performance. (Fig.1)
2. Install the range hood directly above the cooktop. The optimal distance between the cooktop and lower edge of the range hood is 24" to 36". (Fig.2) Install at the height appropriate to your ceiling. Make sure the chimney reaches the ceiling. If your ceiling leaves the hood a few inches higher or lower than 24" to 36" you can still install it without a major loss of performance.
3. For optimal performance, do not over extend the exhaust tube and avoid unnecessary bending. (Fig.3)
4. After hanging the unit on the wall, ensure the range hood is straight and leveled. (Fig.4)
5. The air outlet must be connected to chimney flumes or combustion gas ducts. Under no circumstances should the air outlet be connected to ventilation ducts for rooms in which fuel-burning appliances are installed.

RANGE HOOD INSTALLATION

Preparing Your Wall / Mounting Instructions

Step 1:

Place the range hood on the wall and mark the position where you want to install. A height of 24" to 36" from the cooktop is recommended for optimal performance. Install at the height appropriate for your ceiling. You may install higher if needed. Make sure the chimney can still reach the ceiling. If your ceiling leaves the hood a few inches higher or lower than 24" to 36" you can still install it without a major loss of performance. There are 3 included brackets. Start your measurements from the top down to make sure the chimney reaches the ceiling with no gap if desired.

* If you intend to run your ducting through the back wall behind the hood, it is not necessary for the chimney to touch the ceiling.

Step 2:

A. Find the Core Unit Bracket (D) that will hold the back of the range hood. Mark the locations on the wall with a pencil or marker.

B. Drill a 5/16" (8mm) hole at each marked location.

C. Insert wall anchors into each hole, gently tapping in place.

D. Take the Core Unit Bracket (Part D) that will hold the range hood and firmly tighten with 3 wood screws (Part B) into the anchors. Secure range hood by hanging on bracket.

Step 3:

Locate the 6" round aluminum duct (F) and attach it to the top air outlet on the main body of the range hood with HVAC foil tape (not included). Make sure it is connected tightly.

Step 4:

Place the bottom of Outer Chimney into Core Body's seating located near vent hole. Then Insert the Inner Chimney cover into the Outer Chimney Cover. Note that the Inner Chimney cover must slide into the Outer Chimney cover's orientation slot. (see step 7 for mounting bracket install)

Step 5:

A. Extend the inner chimney cover to the height at which it will touch the ceiling. Using a pencil, place a small mark on each side of the chimney cover which is level with the screw holes of the chimney. Now slide the inner chimney cover down.

B. Using a pencil, place a small mark on the wall on each side of the chimney.

C. Align the middle of the Inner chimney bracket (H) with the drawn line and make a mark where each screw hole in your wall will need to be drilled for mounting of the bracket.

D. Drill 1/4" holes at each marked location. The drilled hole should be slightly smaller than the diameter of the anchor.

E. Insert anchors into each drilled hole.

F. Align Inner chimney bracket (H) with the drilled holes and firmly screw it into place. Use 3/8" screws (parts list C).

Step 6:

Extend the 6" Duct to the vent pipe of your building or outside. For optimal performance try to minimize bending of the duct.

Step 7:

Mount outer chimney bracket (E) to the wall appropriate to the height of the outer chimney. Use the hooks on bracket to mount bottom chimney. Extend Inner Chimney until it touches the ceiling. Align sides with Inner Chimney Mounting Bracket (H) (already mounted to wall) and firmly screw sides of Inner Chimney to bracket with 3/8" screws (C in parts list).

* If you intend to run your ducting through the back wall behind the hood, it is not necessary for the chimney to touch the ceiling.

Step 8:

Insert and install filters according to the diagram on Next Page. Start at 90° Angle and line up the hooks on filter with the rectangular slots on the range hood. Lift the filter up and push the button on filters to allow it to lock into place.

BAFFLE FILTER INSTALLATION

Step 1: Line up filter Hooks to holes in unit.

Step 2: Lift filter for Hooks to go into holes.

Step 3: Lock Filter into place by pressing the button in and down.

RECIRCULATING CHARCOAL FILTERS

Skip this page if you are installing a Ducted Range Hood. Charcoal Filters are only included with Ductless Models.

Step 1: Remove the ARC-FLOW Baffle Filters.

Step 2: Locate the motor (pictured below) and align one of the filters with the right side of the motor.

Step 3: Twist and lock the filter into place.

Step 4: Repeat Steps 2-3 on the left side of the motor.

Step 5: Reinstall the ARC-FLOW Baffle Filters back into place.

NOTE: Chimney vent holes must be open and visible for the filtered air to recirculate.

Diagram shows a range hood unit for recirculating air, with labels for 'Chimney vent holes'. Also shows roof venting options: A. Chimney hole, B. 6" (15.2 cm) round vent, A. Roof cap.
