INSTALLING THE INLET TUBING
When your planning is complete, you will have to
determine where all the inlets and the power unit will be
located. You have also mapped out the location of your
trunk line and found the access you need to run vertical
tubing from one level of your house to another level.
You should have acquainted yourself with the methods of
joining plastic tubing and acquired the tools you’ll need to
install your NuTone Central Vacuum System. Now, you
can begin installation.
The first step to install the inlet tubing which connects the
wall inlets to the branch lines. As explained before, the
inlet lines run inside interior walls. You will find access to
these walls through your attic or basement. Briefly, you
want to find the exact location in the wall, drill an access
hole through the wall plate or header, and insert the
tubing into the wall cavity.
This part of your installation requires close observation
and careful measurements. Take your time and make
sure you accurately line up your access holes with the
locations you’ve chosen for your wall inlets.
Locating Attic Access Holes
Drill the access holes directly above the inlet location.
To accurately locate the access hole, you must find the
space between wall studs where the inlet is to be located.
Observe the area around the inlet location. Look for
references you might be able to find in the attic: electrical
wiring, ductwork, doorways, etc. Measure and note the
distance from these references to the inlet location.
Enter the attic and find the inlet wall. Have a helper
downstairs knock on the top of the wall right above the
inlet location; locate the general area by following the
sound. Most likely, you will have to clear away insulation.
Ask your helper to continue knocking until you locate the
area between wall studs directly above the inlet location.
Next, measure the thickness of the wall. Mark the exact
center of the wall where you will drill the access hole.
Remember that the access hole must be placed exactly
in the center of the wall.
Locating Basement Access Holes
To locate access holes in the basement, remove the toe
molding or baseboard at the base of the inlet wall.
Carefully loosen the molding or baseboard by inserting
the blade of a putty knife behind it. Force another putty
knife between the first knife and the baseboard or wall.
Gently hammer a cold chisel between the two knife
blades, prying the loosened molding away from the
baseboard or the baseboard away from the wall.
Directly below the inlet location, drill a 1/16” reference hole
through the floor into the basement. (If you’re drilling through
carpet, use an awl to slightly open the weave. This will keep
the carpet from wrapping itself around the drill bit.) Insert a
piece of scrap wire or a clothes hanger into the reference
hole so you can easily find the hole in the basement.
Once you’ve found the location in the partition wall, you
must center the access hole in the middle of the wall.
Measure half the thickness of the wall and mark the
center of the wall where you will drill the access hole.
If you cannot see the plate, you can determine this
measurement from upstairs. At the nearest doorway,
measure the thickness of the wall, including the
baseboard.
In the basement measure a distance equal to half
the thickness of the wall, using the reference hole as a
starting point.
