PLAN YOUR DUCTWORK
The Inca HC requires 6" round ductwork. To ensure that the blower performs to its highest possible capac- ity, ductwork should be as short and straight as possilbe.
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 | |

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.

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.
