MODEL 660-FC, Flush mounted, power Cord
For New Construction, In-Wall with Power Cord Attached
Note: Two studs must be on 16” centers or 14-1/2” (36.8 cm) between studs.
If the studs are further apart, have the carpenter install another stud or attach only one flange to a stud and
let the other side float, the vacuum will clamp it to the drywall.
The power receptacle should be in reach of the vacuums electrical cord, 5 feet long.
Installing the Frame in a 2 x 4 wall without drywall installed:
1. Use the large mounting frame and slide it between the two studs. Adjust the height position so that the customer
can access the vacuum comfortable. The horizontal hole in the frame should be the lower part when installed.
2. Use the supplied eight fasteners to attach the frame in place.
3. Glue the pipe reducer K-384 to your pipe coming from the ceiling.
4. Guide the pipe and reducer into the cage on top of the frame. Turn the reducer so that it cannot be pulled up.
5. Pull the low voltage wires from the pipe’s installation into the center of the frame. Curl them up or tape them to a
stud to prevent the dry-wall installer from cutting the wires when he removes the dry-wall from the center of the frame.
After drywall is installed, cut out the center of the frame:
6. To remove the door from vacuum, place your hand on the curved bracket at the top of the door and pull toward you.
You will see four screw heads in the corners with clamp-blocks outside the housing, behind the screws.
7. Find the low voltage wires inside the wall. Connect them to the yellow wires in the back of the vacuum. Be sure to
keep the yellow low-voltage wires in the groove on the back of the vacuum cleaner. Clamp the wires into the two
small wire holders on the top back side, to the right. This prevents the wires from falling behind the vacuum. There
will only be 1/16th inch (1.5 mm) of space between the back drywall (2X4) and the back of the vacuum.
8. Hold the vacuum parallel to the frame opening and slide into the opening
9. Tighten the four screws. They will clamp around the back side of the frame.
