[. . . ] Give the screw a few turns until it firmly engages in the mounting plate. Now, level and slightly lower the assembly. 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. Complete all your wall inlet installations in this manner. If your cutouts are accurate, each wall inlet will install more quickly and easily. Apply cement to tube and install flanged wall fitting. Make sure fitting is well seated and sealed (Figure 33). Remove plaster frame from mounting bracket. Pull low voltage wire through hole in bracket and insert bracket into cutout. Secure bracket to flanged fitting with four screws provided. 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.
