INSTALLATION IN EXISTING CONSTRUCTION

Use the following procedures for installation in existing construction.
Starting from farthest wall inlet location, install each inlet as described
below. Working back toward power unit, connect each inlet line and
branch line into main trunk line. See page 5. Complete low voltage wiring						BASEBOARD
as main trunk line is continued back to power unit. Mount power unit and
complete wiring. See page 8.
							TOE STRIP
WALL INLET INSTALLATION
1. See Figure 29. A small ‘pilot’ or ‘locating’ hole can be drilled behind
baseboard toe strip to determine proper location of 21⁄2" diameter tubing			SOLE PLATE				PILOT HOLE
hole in sole plate.					“X”
		FIGURE 28
2. Measure the total thickness of the wall, including baseboard. One half of
this wall thickness measured from the pilot hole (dimension ‘X’) will
determine the proper location of the 21⁄2" tubing hole in the sole plate.
3. Once desired inlet locations have been determined, cut a 21⁄2" hole in
sole plate directly in line with proposed inlet location. Check through							FLANGED
tubing hole to be sure no obstruction exists.							FITTING
4. Be sure tubing hole is centered in sole plate and directly in line with
proposed wall inlet cutout.

5. If area is clear, cut an inlet opening in the wall approximately 18" above the floor.							WIRING
Make sure wall opening and 21⁄2" tube hole line up (Figure 29).
6. 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.
7. Apply cement to tube and install flanged wall fitting. Make sure fitting is well seated
and sealed (Figure 30).				FIGURE 30
8. 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 31).
9. Attach the low voltage wires to terminal screws on back of wall
inlet (Figure 32).
10. Insert wall inlet into bracket and secure with the two screws
provided (Figure 33).
