Faber Inca Pro 38 Recirculating Installations, Plan Your Ductwork, Make Your Cut-Outs

RECIRCULATING INSTALLATIONS

IT IS HIGHLY RECOMMENDED THAT PROFESSIONAL STYLE COOKING ALWAYS BE VENTED TO THE OUTSIDE. For recirculating installations (FIGURE 1), Charcoal Filters are necessary. Remove all three grease filters and set aside. Attach one charcoal filter to each end of both blowers. Each charcoal filter attaches to the grid on the side of the blowers. Rotate the filter clockwise to install and counterclockwise to remove (FIGURE 1A). Replace all three grease filters. Recirculating installations also require some duct work to divert the air out of the top or face of the cabinet or custom hood. The duct work must not terminate inside the cabinet or custom hood.

PLAN YOUR DUCTWORK

To ensure that the blower performs to its highest possible capacity, ductwork should be as short and straight as possilbe.

The ductrun should not exceed 35 equivalent feet if ducted using two separate duct runs of the required minimum of 6" round duct or 55 equivalent feet if ducted with one single 10" round duct (when using optional Duct Transi- tion Kit). Calculate the length of the ductwork by adding the equivalent feet in FIGURE 2 for each piece of duct in the system An example is given in FIGURE 3.

90˚ Elbow			5.0 feet
90˚ Flat Elbow			12.0 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. If you must elbow right away, do it as far away from the hood's exhaust opening as possible.

MAKE YOUR CUT-OUTS

1.Disconnect and move freestanding range from cabinet opening to provide easier access to upper cabinet or custom hood. 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 or custom hood where the rangehood will be installed.

3.Determine and make all necessary cuts in the wall and/or ceiling 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 4).
