The ductrun should not exceed 35 feet if ducted with the required minimum of 6" round duct. Calculate the length of the ductwork by adding the equivalent feet in FIGURE A for each piece of duct in the system An example is given in FIGURE B. 45° Elbow 3.0 feet 90° Elbow 5.0 feet 90° Flat Elbow 12.0 feet Wall Cap 0.0 feet FIGURE A 9 Feet Straight Duct 9.0 feet 2 - 90° Elbows 10.0 feet Wall Cap 0.0 feet Total System 19.0 feet FIGURE B For best results, use no more than three 90° elbows. Make sure that there is a minimum of 24" of straight duct between elbows if more than one is used. Do not install two elbows together. The Inca HC power pack rangehood is designed to offer a wide flexibility of installations. The rangehood can be ducted vertically (FIGURE 2) or horizontally (FIGURE 3) through a 6" round vent. The unit can also be installed in a recirculating configuration (FIGURE 4). The unit comes standard in top venting position. HORIZONTAL DUCTING FIGURE 2 VERTICAL DUCTING FIGURE 3 For direct rear venting, you must change the blower position. Remove the 2 black screws from the control panel (A in FIGURE 2). This allows the control panel to slide through its housing, providing the necessary wire slack needed to rotate the blower housing. Remove the 12 screws that hold the metal housing to the rangehood body. Remove the 4 screws that hold the blower housing to the metal housing. Rotate the blower 90 degrees toward the back and then flip it over 180 degrees. Be sure that the power supply cable is properly positioned in the nearest hole. Replace all screws, making sure that they are firmly fastened. Reinstall control panel. RECIRCULATING INSTALLATIONS For recirculating installations (FIGURE 4), Charcoal Filters are necessary. Remove all three grease filters and set aside. Attach one charcoal filter to each end of the blower. Each charcoal filter attaches to the black grid on the side of the blower. Rotate the filter clockwise to install and counterclockwise to remove (FIGURE 4A). Replace all three grease filters. Recirculating installations also require some duct work to divert the air out of the cabinet. The duct work must not terminate inside the cabinet. The plastic vent grate supplied with the rangehood (FIGURE 4B) can be used to cover the duct opening.

Disconnect and move freestanding range from cabinet opening to provide easier access to upper cabinet and rear wall. Put a thick, protective covering over cooktop, set-in range or countertop to protect from damage or dirt. 2. Determine and clearly mark with a pencil the center line on the cabinet where the rangehood will be installed. 3. Determine and make all necessary cuts in the wall for the ductwork. Install the ductwork before the rangehood. 4. Determine the proper location for the Power Supply Cable. Use a 1 1/4" Drill Bit to make this hole. Install the cable. Use caulking to seal around the hole. DO NOT turn on the power until installation is complete. 5. Make the cut-out opening where the rangehood will be installed (FIGURE 5). CUT-OUT 13 5/32" 27 5/8" FIGURE 5 INSTALL THE RANGEHOOD 1. Remove the rangehood from the carton and place on a flat surface. Cover the surface to prevent accidental damage. Remove all parts including the backdraft damper, plastic grille and literature package before discarding the carton. 2. Remove the grease filters from the rangehood and set aside. The grease filters are removed by pressing the handle of the filter as indicated in FIGURE 6. When replacing, make sure that the filters are properly positioned with the handles in front and visible. FIGURE 6 3. Place the round damper into the exhaust opening of the rangehood and press down. 4. The rangehood mounts to the cabinet by two spring loaded brackets, one on each side of the rangehood. Lift the rangehood into the cutout opening in the cabinet. Be careful not to damage the cabinet, rangehood or other appliances. 5. Tighten the rangehood to the cabinet by rotating the screws indicated in FIGURE 7 with a phillips screw driver. FIGURE 7 6. Remove the cover from the field wiring compartment with a phillips screwdriver. Feed the Power Supply Cable through the electrical knockout. Connect the Power Supply Cable to the rangehood cable. Attach the White lead of the power supply to the White lead of the rangehood with a twist-on type wire connector. Attach the Black lead of the power supply to the Black lead of the rangehood with a twist-on type wire connector. Attach the Power Supply Cable grounding lead to the green screw provided. Using the 4 holes provided screw the field wiring compartment to the wall or cabinet as dictated by your Power Supply Cable location (screws not provided). Replace the cover. 7. Replace the grease filters. 8. Connect the duc...
