CONNECTION FROM BEHIND

Refer to Figure 49.

1. Turn the power to the vacuum unit OFF. Choose a

location under the cabinet for the VacuSweep

Inlet

Valve so that it can be connected to the central vacuum

pipe. Measure distance (X) between the kickplate face

and the inside edge of the cabinet. Then add 2¾” to the

measured distance. See Figure 49-1. Measure out the

new distance (X + 2¾”) from the cabinet door, to the

reference mark.

2. Drill a small reference hole straight down through to the

basement. See Figure 49-2. Locate the reference hole in

the basement and verify that there are no obstructions.

3. Using a reciprocating saw, cut an access hole in the floor

under the cabinet and approximately 8” behind the

location of the VacuSweep

Inlet Valve reference hole so

that the VacuSweep

Inlet Valve can be connected to

vacuum pipe by reaching through the access hole.

See Figure 49-3.

CONNECTION IN A WALL

Refer to Figure 50 on page 25.

1. Turn the power to the vacuum unit OFF.

Remove the baseboard and locate studs in

the wall where VacuSweep

Inlet Valve will be

installed. Locate a position where the inlet will

be clear of vertical studs and have free

access either up or down dependent on

location of central vacuum connection to the

rest of the system. See Figure 50-1.

2. Holding the drill at a 45˚ angle and as close

to the wall as possible, between located

studs, drill a small reference hole through the

floor and subfloor. Locate this reference hole

from beneath and measure over approximately

⁄8” to center of base plate of wall. Ensure you

have 1½" clearance from any obstacles if

connecting from below. See Figure 50-2.

3. If installation is from below use a 2½”

diameter hole saw to remove wood floor and

base plate, sufficient to locate VacuSweep

Inlet Valve centered over the reference hole.

See Figure 50-3.

4. Using the reference hole as a center, cut a

⁄8” high x 6

⁄8” wide rough opening in the wall

and baseboard. See Figure 50-4.

5. Glue the long socket of the tight elbow

(part no. CF382S) onto a section of 2” central

vacuum pipe. Make the terminal connections

to the VacuSweep

Inlet Valve by sliding the

lowvoltage wire into wire clips. Turn the power

to the vacuum unit on to test the connection.

After successful completion of the test, turn

power to the vacuum unit OFF. Wrap a piece

of wire/string around the pipe. Using the

AD0046A

FIGURE 49

4. Using the reference hole as a center, cut a 2

⁄8” high x 6

⁄8” wide

rough opening in the kickplate face. See Figure 49-4.

5. Insert a coupling (part no. CF388) onto the rear of the

housing. DO NOT glue this connection (Designed for

friction fit). See Figure 49-5. Make the terminal

connections to the VacuSweep

Inlet Valve by sliding the

low voltage wire into wire clips. Turn the power to the

vacuum unit on to test the connection. After successful

completion of the test, turn power to the vacuum unit

OFF. Insert the VacuSweep

Inlet Valve into the cabinet

base and pipe.

6. With the door in an open position, secure the

VacuSweep

Inlet Valve to the cabinet base using no. 6

screws. See Figure 49-6. Ensure that the spring on the

electrical connector has 1/8” clearance to rough

opening. From the basement reach through the access

hole and glue a section of 2” central vacuum pipe to the

coupling. Continue with remainder of central vacuum

connections. When the vacuum system is complete, turn

the power to the vacuum unit on.
