9WALL INLET INSTALLATIONModel CI370 Wall Inlet (CF361 and CF361FRough-In)1. Remove the cardboard plaster guard.2. Refer to Figure 20. For some drywall or panelconstruction, the plaster frame will extend beyond thefinished wall. In this case, remove plaster frame frommounting bracket by removing mounting screws.NOTE: When using the model CF361 and CF361F inletbracket on walls thinner than 1⁄2", use a 1⁄4" spacer (notfurnished) between the wall and the inlet bracket. SeeFigure 23. Spacer may be made from plywood, Masonite™,etc. Contact cement may be used to hold spacer in placeduring assembly. Configuration of spacer may vary dependingupon installation.3. Refer to Figure 21. Connect the red striped wire of the2-conductor low voltage cable to the unused terminalscrew on the inlet. Connect the remaining wire to theblack pigtail wire. Cap off both wires using wire nut(supplied).NOTE: The LED indicator light used in the CI370 is polaritysensitive. If the 2-conductor cable used to connect the inletto the power unit does not have a polarity marking and theCI370 is wired backwards, no damage will result;however, the indicator will light RED instead of GREENwhen the hose is inserted into the inlet. To correct thiscondition, simply reverse the 2-conductor connections at theCI370 inlet.4. Guide excess wire back through the hole in inlet bracketand flanged fitting.5. Refer to Figure 26. Place inlet into mounting bracket andsecure.NOTE: When wall inlets are installed in walls that are lessthan 1⁄2" thick or when inlets are installed back-to-back in awall, the tube of the wall inlet may extend into elbow area ofthe flanged fitting and cause blockage. Shorten the wall inlettube to prevent this condition. Refer to Figure 24.For extra thick walls, use Model 399 Extension Sleeve toconnect inlet to the flanged fitting.Model 360 Wall Inlet (CF361 and CF361FRough-In)1. Follow steps 1-2 as above.2. Refer to Figure 25. Connect 2-conductor low-voltagewire to terminal screws on back of wall inlet.3. Follow steps 4-5 above.Model 330 Wall Inlet (CF329 Rough-In)See Figure 261. Connect 2-conductor low-voltage wire to terminal screwson back of wall inlet.2. Align inlet mounting holes with holes in mounting plate.See Figure 26.3. Place inlet into mounting plate and secure with twoprovided screws.
