Wall Inlet Installation; Model 330 Wall Inlet - NuTone CV850 Instrucciones De Instalación

INSTALLATION IN NEW CONSTRUCTION

WALL INLET INSTALLATION

Your CV850 Power Unit is designed especially for model CI370
Series Indicating Inlets. These inlets include a LED to remind you
after 25 hours of operation that it is time to change the filter bag in
your power unit. Any other NuTone inlets may
be used as well.
MODEL CI370 WALL INLET (361 Rough-In)
1. Remove the cardboard plaster guard.
2. Refer to Figure 17. For some drywall or panel construction, the
plaster frame will extend beyond the finished wall. In this case,
remove plaster frame from mounting bracket by removing
mounting screws.
NOTE: When using the Model 361 inlet bracket on walls thinner
than 1 ⁄ ", use a 1 ⁄ " spacer (not furnished) between the wall and the
2 4
inlet bracket. See Figure 20. Spacer may be made from plywood,
Masonite™, etc. Contact cement may be used to hold spacer in
place during assembly. Configuration of spacer may vary
depending upon installation.
3. Refer to Figure 18. Connect the red striped wire of the 2-
conductor low voltage cable to the unused terminal screw on
the inlet. Connect the remaining wire to the black pigtail wire.
Cap off both wires using wire nut (supplied).
NOTE: The LED indicator light used in the CI370 is polarity
sensitive. If the 2-conductor cable used to connect the inlet to the
power unit does not have a polarity marking and the CI370 is
wired backwards, no damage will result; however, the indicator will
light RED instead of GREEN when the hose is inserted into the
inlet. To correct this condition, simply reverse the 2-conductor
connections at the CI370 inlet.
4. Guide excess wire back through the hole in inlet bracket and
flanged fitting
5. Refer to Figure 19. Place inlet into mounting bracket and
secure.
NOTE: when wall inlets are installed in walls that are less
than 1 ⁄ " thick or when inlets are installed back-to-back in a
2
wall, the tube of the wall inlet may extend into elbow area of
the flanged fitting and cause blockage. Shorten the wall inlet
tube to prevent this condition. Refer to Figure 21.
For extra thick walls, use Model 399 Extension Sleeve to connect
inlet to the flanged fitting.
MODEL 360 WALL INLET (361 Rough-in)
1. Follow steps 1-2 as above.
2. Refer to figure 22. Connect 2-conductor low voltage wire to
terminal screws on back of wall inlet.
3. Follow steps 4-5 as above.
MODEL 330 WALL INLET (329 Rough-in)
See Figure 23.
1. Connect 2-conductor low voltage wire to terminal screws on
back of wall inlet.
2. Align inlet mounting holes with holes in mounting plate.
3. Place inlet into mounting plate and secure with two provided
screws.
