[. . . ] BUILT-IN CENTRAL CLEANING SYSTEM INSTALLATION INSTRUCTIONS For Power Unit Models VX475, VX550, VX1000 VX475C, VX550C, VX1000C TABLE OF CONTENTS SYSTEM PLANNING AND LAYOUT . . 36-37 2 SYSTEM PLANNING AND LAYOUT The NuTone Central Cleaning System consists of a Power Unit, PVC Tubing and Fittings, Wall Inlets, a flexible Hose and various cleaning Attachments. The Power Unit is designed to be wall-mounted away from the living area of the home and connected to the living area by means of permanently installed in-wall tubing, fittings and inlets. Generally, an installation will require 3 to 4 inlets and 16 to 20 feet of tubing per inlet. [. . . ] For plaster walls, score the plaster deeply, being careful to stay inside the marked line. Now, remove the nail flange (used for new construction) from the inlet mounting plate. Use pliers to bend this flange along the scored lines until you can break it off. Next, use a keyhole saw or a sabersaw to make the cutout. Again, be extremely careful to cut along the inside of the marked line. Caution: When cutting into plaster walls, make sure the plaster is firm and secure around the cutout area. Apply cement to both the inside of the flexible tubing and to the outside of the mounting plate's tube ring. Insert the mounting plate's tube ring in the flexible tubing and twisting the pieces as you join them to spread the cement, and align the mounting plate in a vertical position. 16 Hold the assembly in a place for a few minutes as the cement sets; allow five minutes for the cement to completely dry. Installing The Inlet When you place the inlet into the wall cutout, the mounting plate and tube guard slip inside the wall; the inlet cover remains on the outside. Holding the inlet assembly between your thumbs and fingers, angle the bottom of the mounting plate into the cutout. Push the assembly downward until you have clearance at the top of the cutout. Push the top of the mounting plate into the cutout and lift the assembly upward until the top screw seats in the predrilled hole. At this point, the wall should be sandwiched between the mounting plate and the frame plate. Now, strip the ends of the two low voltage wires, and then connect the wires to the screw terminals on the back of the inlet cover. When the wiring is complete, assemble the inlet cover to the tube guard and mounting plate. Insert the top screw through the entire inlet assembly until the screw engages the mounting plate. Completing The Inlet Assembly Once you have attached the mounting plate to the flexible tubing, pull the low voltage wire through the top wiring hole in the mounting plate. 17 Insert the bottom screw into the inlet cover and through the other parts. Give the screw a few turns until it firmly engages in the mounting plate. Make sure the wall is sandwiched between the inner and outer parts ­ you'll be able to feel if mounting plate is firmly centered on the inside of the wall. Hold the inlet in place and gradually tighten down each screw a little bit at a time. (If you completely tighten down one screw at a time, the mounting plate may pull away from the wall at the loose end and slip back into the cutout. ) MODEL CI370 or 360 SERIES INLETS (CF361 or CF361F Rough-In) NOTE: If 330 Wall Inlet is being used refer to Model 330 Wall Inlet Installation on next page. If area is clear, cut an inlet opening in the wall approximately 18" above the floor. Make sure wall opening and 2 1/2" tube hole line up (Figure 32). FIGURE 32 NOTE: If the wall for mounting the Model 360 inlet is less than 1/2", a spacer must be used. Cut a length of tubing that will extend from inlet opening to a point below floor level (or above ceiling level in attic installation). Tape low voltage wire to tube and insert tube through predrilled hole to a level opposite the wall opening. If your cutouts are accurate, each wall inlet will install more quickly and easily. Pull low voltage wire through hole in bracket and insert bracket into cutout. Be sure seal is secure between flange fitting and mounting bracket (Figure 34).

[. . . ] If Central Cleaning hose is not available at the time, a short piece of wire can be used to short contacts in wall inlet to activate power unit. Make sure the filter bag is properly installed in the power unit according to directions printed on the bag or in homeowner's manual. Remove the extra bag and owner's manual from the power unit dirt receptacle. It may be convenient to store them with the cleaning tools and accessories. [. . . ]
