LESS THAN 7 INCHES Figure 9 OFFSET INSTALLATION Typical use of duct offset to match air filter opening. If duct connection to furnace allows less than nine inches for mounting the air filter, shorten the lateral trunk, or attach an offset fitting to the elbow. 5 INSTALLATION REMOVE OLD FILTER AND DISCARD (Figure 11) NOTE: This filter may be mounted in the furnace compartment. CLEAN BLOWER COMPARTMENT NOTE: The air filter cannot remove dirt from blower and ducts. INSTALLATION The following is a typical installation of the air filter on a “Highboy” furnace (Figure 7). 1. Place the air filter compartment on the floor. Stand it upright with the door facing you (Figure 2). If a horizontal installation is being planned, lay the compartment on its side, this will help you to visualize the relative location of all parts. 2. Remove the door (by grasping top and pulling door away from compartment) and set it aside. Remove 4” filter by grasping it at the top and bottom. Set in a safe location until the cabinet is installed. 3. Set the compartment next to the furnace (if possible) to match the opening in the compartment. If the furnace opening cannot be enlarged, a transition fitting should be used. (Figure 3). The compartment can be attached directly (Figure 12), or a starting collar can first be fitted to the furnace inlet. A butt or slip joint can be used. Securely attach the compartment to furnace inlet, using at least two of the mounting holes on each side of the compartment. 4. Using butt joint, attach duct work (normally an elbow) to the upstream side of air filter compartment. (Note the use of the sheet metal turning vanes inside the elbow to improve air distribution.)
