CENTRAL CLEANING SYSTEM
Indicating Inlets
MODELS: CI370 Series
USE ONLY WITH CV653, CV750 & CV850 POWER UNITS
Mounting Bracket
MODEL: 361
INSTALLATION
1. Once the locations for wall inlet locations have been
determined, mount all inlet brackets.
2. To locate bracket on wall stud, measure approximately 18" up
from finished floor level. (Height location may vary according to
individual preference.)
3. Refer to Figure 1. Nail bracket to side of stud so that front
edge of bracket is flush to front of stud. (The bracket may also
be nailed to the front edge of the stud. For front stud mounting,
use locating tabs on bracket for proper alignment.)
4. Refer to Figure 2. Remove cardboard from plaster guard
frame. Using four (4) provided screws, attach the appropriate
flanged fitting and inlet seal to back of inlet.
5. Replace cardboard into plaster guard frame.
6. Plumb tubing to inlet. Run 2-conductor (376 or 376UL)
low voltage cable between inlet and power unit.
CAUTION: When tubing is run through the wall stud, sole
plate, headers – or anywhere that building materials will be
attached – place a nail plate (Model 378) over that area (on
both sides if necessary) to prevent nails from piercing tubing.
WALL INLET INSTALLATION
1. Once the walls have been finished, install the wall inlets.
2. Remove the cardboard plaster guard.
3. Refer to Figure 3. For some dry wall 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 1⁄2", use a 1⁄4" spacer (not furnished) between
the wall and the inlet bracket. See Figure 3A.
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.

FINAL SYSTEM CHECK
Be sure all inlets are closed and soil bag is in place. Check switch on power
unit for manual on/off operation.
Check each wall inlet to be sure contacts activate indicator light and power unit
when hose is inserted. A short piece of wire can be used to short contacts in wall
inlet together to activate power unit. Check each wall inlet and tubing connection
for air leaks. Check power unit for leaks around inlet tube and dirt receptacle.
Note:
If indicator light is RED when the hose is inserted, reverse the wiring of the
2-conductor cable at the CI370 inlet (see fig 4).
For a hose that has an ON/OFF switch on the hose, the light on the inlet will be
activated only when the hose is switched “ON”.

4. Refer to Figure 4. 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
pig tail 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.
5. Guide excess wire back through the hole in inlet bracket
and flanged fitting.
6. Refer to Figure 5. Place inlet into mounting bracket and
secure.
NOTE: When wall inlets are installed in walls that are less
than 1⁄2" thick or when inlets are installed back-to-back in
a 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 6.
For extra thick walls, use Model 399 extension sleeves to
connect inlet to the flanged fitting.
