Place the air filter cleaner on the floor. Stand it uprightwith the power door facing you (Figure 4). If ahorizontal installation is being planned, lay the cleaneron its side, this will help you to visualize the relativelocation of all parts.Allow ample space for wiring and servicing the powersupply box (Figure 13).2. Release the latch, remove the power pack (by grasp-ing handle and pulling power pack away from cabinet)and set it aside. Remove the collecting cells and pre-filters. Set pre-filters and cells aside in a safe locationuntil the cabinet is installed.3. Set the cabinet next to the furnace. If necessary,enlarge the opening in the furnace (if possible) tomatch the opening in the cabinet.If the furnace opening cannot be enlarged, a transi-tion fitting should be used. (Figure 3).The cabinet can be attached directly (Figure 13), ora starting collar can first be fitted to the furnace inlet.A butt or slip joint can be used.Securely attach the cabinet to furnace inlet, using atleast two of the mounting holes on each side of thecabinet.4. Using butt joint, attach duct work (normally an elbow)to the upstream side of air cleaner cabinet. (Note theuse of the sheet metal turning vanes inside the elbowto improve air distribution over the face of the cells.)(Figure 14)NOTE:NOTE:NOTE:NOTE:NOTE: An optional method of attaching duct work to thecabinet is to modify the cabinet (Figure 15) by bending thetabs outward at a 90° angle and attaching duct work totabs.Transition FittingsTransition FittingsTransition FittingsTransition FittingsTransition FittingsIf the air duct does not fit the cabinet opening, a transitionfitting should be used. Gradual transitions are preferredfor greatest efficiency. Not more than four inches perlinear foot (approximately 20° angle) should be allowed(Figure 3).5. Connect the vertical duct section to the elbow. Wedgea wood block between floor and elbow for support(Figure 16).6. Seal all joints in the return air system downstreamfrom the air cleaner with duct tape to prevent dustfrom entering the air stream. Tape is usually appliedon the outside of ducts, but may also be applied on theinside, or both.INSTALLATIONINSTALLATIONINSTALLATIONINSTALLATIONINSTALLATION
