New Construction

After the house has been wired and plumbed, but before the dry wall is installed is the best time to pipe in a central vacuum tubing system. Locate the inlet valve locations and nail the mounting plate to the nearest stud. Make sure the middle of the mounting plate is at the same height as the middle of adjacent electrical outlets.

It is best to offset the tubing using a combination of a tight 90 degree fitting and a 45 degree elbow. This will avoid problems of mounting screws puncturing the tubing as well as allowing the hole to be drilled further away from the stud where nails could ruin the hole saw. Drill a 2 1/2" hole in the centre of the top or sole plate depending on the location of the trunk line. Attach low voltage wire to the tubing and push the tubing through from the floor below and cement it to the forty-five degree fitting. Leave ten inches of low voltage wire at the mounting plate for valve installation when the house is completed.

Once the house is completed the inlet valves must be installed. Bare a half inch of the low voltage wire leads and wrap them in a clockwise direction around the lugs on the back of the valve. Tighten the lugs with a screwdriver. Using a twisting motion insert the valve into the hole with the hinge at the top of the valve. Do not apply glue; the gasket in the mounting plate will provide a positive seal. If the valve will not reach the mounting plate ask your dealer for an inlet valve extension part no. M399. Using the screws supplied, attach the inlet valve to the mounting plate. Use the extra short screw if the longer version is going to penetrate the tubing behind.

Note: Do not over tighten. If a whistling develops during operation slightly loosen the screws.
