User manual NUTONE 1M-3003

[. . . ] 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. [. . . ] Place the template against the wall so that it is 18" on-center from the floor. Mark your wall for the cutout by tracing around the inside of the template. Then use your pencil to mark the screw hole locations through punched holes at the top and bottom of the template. Remove the template from the wall. For a basement installation, assemble the tubing to the inlet flexible tubing in the same way and insert it into the access hole. A basement inlet line is necessarily shorter because it must only reach 18" from the floor to the inlet. Most of the time, Basement inlet lines are more easily installed by two people after the inlet hole has been cut in the interior wall. See "Installing The Wall Inlet. " Complete all your inlet lines, and then proceed to your inlet installations. 15 Use an awl or icepick to punch pilot holes where you marked the two hole locations. Now, drill two 3/8" diameter holes, using the pilot holes as the centers. Take care to locate and drill these holes exactly as marked with the template. Attaching The Inlet Mounting Plate Reach through the inlet hole and locate the inlet tubing. If the inlet is connected from the basement, have a helper insert the inlet tubing into the access hole until you can see the flexible tubing. Then, pull the flexible tubing through the inlet hole and remove the low voltage wiring from inside the tube. 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). FIGURE 33 18 MODEL 330 & CI335 Series WALL INLET Installation (CF329 Rough-in) FIGURE 34 5. Attach the low voltage wires to terminal screws on back of wall inlet (Figure 35). If using 361 Rough-in with CI370 Series Inlets, refer to instructions on page 6, step 3, shown in Figure 18. FIGURE 37 FIGURE 38 FIGURE 39 FIGURE 40 1. Insert wall inlet into bracket and secure with the two screws provided (Figure 36). 3. Glue elbow to mounting plate, place assembly into cutout, and attach elbow to tubing inside the wall. Connect 2-conductor low voltage wire to terminal screws on back of wall inlet. Align inlet mounting holes with mounting plate holes, place inlet into mounting plate, and secure with provided screws. NOTE: If CF382S shorter radius elbow is used, it may be necessary to use the short mounting screw to avoid interference with elbow. FIGURE 36 19 Floor Inlet Installation in New & Existing Construction MODEL CI370 or 360 SERIES INLETS (361 Rough-in) 1. After floor inlet location has been selected, cut a 3 1/16" x 2 9/16" square hole in floor. Center line of inlet must be located at least 2 1/2" from wall to allow cover to be opened when hose is inserted. Determine direction of tubing and attach appropriate flanged fitting to mounting bracket with four (4) screws supplied. [. . . ] Do not modify the plug provided with the appliance ­ if it will not fit the outlet, have a proper outlet installed by a qualified electrician. VX475 & VX550 SERIES VX1000 SERIES FIGURE 55 FIGURE 56 33 FINAL SYSTEM CHECK Be sure all inlets are closed and soil bag (for VX475, VX550 & VX1000 models) is in place. Check that indicator light on side of power unit is lit and is in green mode. Check each wall inlet to be sure contacts activate power unit when hose is inserted and switched on, if applicable. If using CI370 or C1358 Indicating Inlet, be sure LED on inlet is green when hose is inserted/switched on. [. . . ]
