Vacuflo 760 Dual Motor Installation Manual - Step 3
Closet Wall Installation of Inlet Valve
If obstructions make it impossible to run vertical tube
lines through partition walls, the best and easiest alter-
native is to go through the insides of closets. This
works especially well when a closet on the second floor
is directly above a closet on the main floor.
Drill a horizontal pilot hole through the center of a
suitable inlet valve location. Probe for hidden obstruc-
tions with a bent piece of coat hanger. With the pilot
hole as a center, drill a 1 1/2" hole through both sides
of the wall. Using a keyhole saw, cut a hole 2 1/4" (57
mm) wide by 3 3/4" (95mm) long in the outside and
inside wall. (See drawing below.)
From Inside the Closet
Feed the low voltage wire
through the top hole of the
mounting plate then through
the wall to the other side.
Attach the 90 adapter to the
mounting plate. Secure
mounting plate flange to the
inside wall with screws to
hold this part temporarily in
position. Install a valve exten-
sion through the wall into the
90 adapter insuring that the flange is at least 1/4”
inside of the wall and that the screw holes are lined up
squarely. Glue this valve extension into the 90
adapter. Allow glue to set - then install wire into valve
and insert valve into valve extension and secure with
screws. Drill a 2-1/4” - 2-9/16” hole below the 90
adapter and connect PVC to trunk line.

Step 3
Floor Installation of Inlet Valve
While the normal installation of inlet valves is in parti-
tion walls, occasionally one must be installed in the
floor. In this case, the location for the inlet valve
should be about two inches from the wall and not in a
high traffic area. As with wall installations, use a pilot
hole drill to make sure the location is clear of obstruc-
tions below. Cut a hole that is 2 1/4" (57 mm) wide by
3 3/4" (95 mm) long. Attach mounting plate to 90˚
adapter elbow. Assemble inlet valve as shown on page
6. Facing wall, valve should open to the left for ease
of use.
In the case of linoleum or uncovered floors, the mount-
ing plate will be installed from below. If the floor is
carpeted, cut a hole in the carpet with a utility knife
and slip the untrimmed mounting plate under the car-
pet. Fasten the mounting plate to the floor with screws.
If a wall or floor is over 1" (25 mm) thick, use inlet
valve stem extension #5018. Shorten extension to fit.
The flange on the extension should be 1/4" (6 mm)
below the surface to insure a proper fit of the valve.

Helpful Hint
For houses with flat roofs
and slab floors, inlet
valves are installed in
exterior walls and branch
lines are run outside the
house. The tubing system
can be run underground
or under the eaves of the
house.
