PLAN THE DUCTWORK
The Cristal HC slideout rangehood is designed to offer wide flexibility of installations. The rangehood can be ducted vertically or horizontally through a 6" round vent. The unit can also be installed in a recirculating configuration. The unit comes standard in the top venting position. FIGURES 1 and 2 show vertical and horizontal installations for this unit. FIGURE 3 shows recirculating installation.
The Cristal HC requires 6" round ductwork. To ensure that the blower performs to its highest possible capacity, ductwork should be as short and straight as possilbe.

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. If you must elbow right away, do it as far away from the hood's exhaust opening as possible.

For direct rear venting (FIGURE 2), you must change the blower position. 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. Replace all screws, making sure that they are firmly fastened.
RECIRCULATING INSTALLATIONS
For recirculating installations (FIGURE 3), Charcoal Filters are necessary. Remove all four 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 3A). Replace all four grease filters. Some ductwork must be installed to exhaust the rangehood back into the kitchen, either at the top of the cabinet or at the face of the soffit. A plastic vent grate (FIGURE 3B) supplied with the rangehood can be used to cover the duct opening. This duct work must not terminate into a dead air space.
