[. . . ] 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. Make sure the wires are tightly secured under the terminal screws. When the wiring is complete, assemble the inlet cover to the tube guard and mounting plate. 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. Make sure mounting holes are exactly at top and bottom. 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. Be sure mounting bracket flange does not interfere with tubing and seal is securely in place. Position bracket with frame and flanged fitting assembly into cutout from below and secure to sub floor. Large end of Model 399 extension sleeve should be cut to length to allow proper seating of inlet against floor or carpet. [. . . ] Power Unit does not start, or shuts off during normal operation with no LED showing Red or illuminated. Note: This would apply only to the VX550 & VX1000: Microprocessor Lockup. Power Unit fails to stop when the hose is removed. Power Unit shuts off during normal operation, lights on Unit, Wall Valve and Hose are all Red. [. . . ]
