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. It is suggested that a floor plan be used to more accurately determine the quantity of materials needed. Use the following examples as an aid in planning the installation in either new or existing construction. You should be able to adapt the examples shown to your specific home layout. THE RANCH STYLE HOUSE Here the power unit is mounted in the garage. The intake and exhaust tubing, the only exposed tubing in the installation, runs up the garage wall and into the attic. The trunk line runs horizontally through the attic from the power unit to the farthest inlet location. Branch lines spread throughout the attic, connecting the trunk line to the inlet tubing. Each inlet tube is threaded vertically through an inside wall. Located in hallways, and in large rooms, the inlets are placed to provide maximum access to all cleaning areas. See Figure 1. FIGURE 1 THE TWO-STORY HOUSE A double-trunk line system is commonly used in twostory houses. In the installation shown at left, the power unit is mounted in the basement. The intake tubing runs up the basement wall and connects to the main trunk line, which runs along the unfinished basement ceiling. Two first-floor inlets are connected to the basement trunk line by vertical inlet lines run through interior walls. In the center of the house, a vertical branch line runs from the basement trunk line, through stacked closets, up into the attic. A second trunk line runs across the attic and two branch lines connect to inlet lines which are dropped down through upstairs interior walls. See Figure 2. FIGURE 2 3 THE SPLIT-LEVEL HOUSE Like the two-story house, the split level installation commonly calls for a two-level trunk line. Here, the power unit is located in the garage. The intake tubing runs exposed up the garage wall and into the ground level section's attic. Two branch lines connect this part of the trunk line to inlet lines which are dropped inside interior walls. A vertical branch line runs to the upstairs attic, where the trunk line branches into a T-shape. This trunk line connects to two upstairs inlet lines and to one inlet line which drops through an upstairs wall and down into the third-level utility room to service this entire level. See Figure 3. FIGURE 3 LOCATING THE POWER UNIT · Locate the power unit at the lowest possible position away from the general living area in an accessible location for changing the filter bag or debris bucket. When planning, remember the power unit is equipped with an inlet to service a garage, basement, utility room, etc., wherever it is located. Locate the power unit within six feet of a grounded electrical outlet. The VX475 and VX550 power units require a 120v 20 amp AC power source. The VX1000 power units require a 240vAC, 15 amp circuit with a NEMA 6-15R receptacle. Do not locate the power unit close to a source of extreme heat (i.e., water heater) or in an area with a high ambient temperature (i.e., attic, furnace room). If the power unit is located in a closet or a small utility room, make sure the area is well-ventilated (i.e., with door louvers). Exhausting the power unit to the outside is recommended for optimal performance. The exhaust should not be vented into a wall, a ceiling or a concealed space in the house. The exhaust line should be vented outside the home using a Model 393 or CI330 wall caps. TUBING AND WALL INLET LOCATIONS 1. Locate inlets on interior walls, choosing central locations which allow several rooms to be cleaned from a single inlet using a 30 foot long hose. 2. The tubing installation should consist of a main trunk line running from the farthest wall inlet to the power unit location, with branch lines running to each additional inlet. Keep all tubing lines as straight as possible and use as few fittings as possible. 3. Beginning at the area farthest from the power unit, choose a tentative inlet location. Measure 30 feet from the proposed inlet location to the farthest corner of the rooms to be cleaned by that inlet to determine if inlet location is proper. If working from blueprints (or building plans drawn at 1/4" = 1 ft. scale), use a 7 1/2" chain as your guide to determine inlet locations. 4. Locate inlets within six feet of an electrical receptacle to allow use of optional current-carrying hose. 5. Be sure inlets will not be blocked by doors or furniture 6. Be sure inlets will not interfere with electrical, plumbing or other mechanical installations. 7. Move tentative inlet location if necessary. Use the same procedure to determine each additional inlet location, always working toward the power unit. · · · · · 4 GENERAL INSTALLATION GUIDE TOOL LISTING Depending on your installation, you may require the use of these tools. The power tools are recommended to make your installation proceed quickly. · · · · · Wire strippers Utility Knife Knife 2 1/2"Hole Saw 1/2" Drill · · · · · 1/4" Drill Putty Knife Hammer Keyhole Saw Cold Chisel · · · · · Level Drill Bit Screwdriver Wrench Tape Measurer · · · · Flashlight Electrical Tape Safety Glasses Hacksaw WORKING WITH PLASTIC TUBING Cutting the Tubing Before you cut a length of tube, accurately measure the length you need. Allow 5/8" of tubing for inserting into fittings and 1 1/2" for placing into flexible tubing. Cut the plastic tubing with a hacksaw, making sure that the cut is exactly square. (You can use a tube cutter if one is available.) Use wire cutters or tin snips to cut flexible tubing. The 8" lengths of flexible tubing supplied with each inlet should not be cut. See Figure 4. FIGURE 5 Next, use a file to slightly bevel the outside of the tube so that it will easily slide into the fitting. Use steel wool or a light grained sandpaper to buff the surface of the tube which will be glued. This will clean the tube and assure a good seal. See Figure 6. FIGURE 4 Use a small knife to remove any burrs from the inside of the tube. You can also use steel wool to remove burrs. The burrs must be removed or they may impede air flow of form clogs by snagging hair and carpet thread. See Figure 5. FIGURE 6 5 Making A Joint Insert The tube into the fitting, aligning the two parts as they will be installed. Mark the tube and the fitting so that you can quickly realign the joint. See Figure 7. Cementing Flexible Tubing Make sure the ends of the flexible tubing are even - trim if necessary. When you join flexible tubing to plastic tubing or to an inlet mounting plate, apply cement to both the inside of the flexible tubing and the outside of the plastic tubing or mounting plate tubing ring. Twist the two pieces as you join them to evenly spread the glue. Allow five minutes for the cement to set in flexible tubing. You may also use electrical tape or duct tape to further seal the joint. Secure Wire To Tubing The low-voltage power wiring is run along with the tubing. To make that the wire is secure and will not hangup in a wall, use electrical tape to attach the wire to the tubing. Tape the wire approximately every 12-18 inches. See Figure 9. FIGURE 7 Apply cement only to the outside of the tube. Dab the cement generously in an inch-wide band. In ...
