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.
