| The
ideal time to install the System is before Dry-Walling. We recommend to
hold off the installation until all Furnace ducts and Plumbing Rough-in
are completed, as it is easier for you to work around these ducts and
plumbing lines than for the sub-trades to work around you. Ideally, the
Main-run should be run along the center of the house from the basement
up.
As the
location of the furnace is usually in the center of the house with the
heating ducts branching out from there, your Main-run could easily be
installed along these ducts. Your System's Main-run will then be concealed
at the same time as when furnace ducts and plumbing-lines are boxed-in
and covered.
TRY
TO COOPERATE WITH THE SUB-TRADES AS MUCH AS POSSIBLE.
If your
home is being built by a contractor, be sure to inform him of your intentions,
as this is an ideal time to request the installation of a separate circuit
to insure sufficient power supply for your System.
The Rough-in
Installation is much simpler and faster than the previously described
installation for finished construction, as the entire working area is
still fully exposed and more easily accessible.
For
the Inlet Valve Installation follow steps 3 and 4 of the mounting plate
installation diagram. When you are ready to install the Power Unit,
follow the same Power Unit "Hook-up" procedure as per
previous chapter.

When the
Rough-in is completed, leave sufficient L.V.T Wire and pipe protruding
near the intended Power Unit location so that the final connection to
the Power Unit can be made easily and quickly without creating unnecessary
extra work when Power Unit is installed.
On the
top surface of the Inlet Kit Boxes you will find a plaster guard and
a mounting plate template. Simply cut along the dotted lines and use
the template to scribe the exact opening for the mounting plate.
In order
to prevent construction debris from entering the installed mounting
plate,firmly push plaster guard into mounting plate
as
per illustration 3 of the mounting plate.
The increased
use of 2x3 wood and metal studs in North American construction methods
demands fittings compatible with these building industry standards.
Our 2021 HXS has been specifically designed for such purposes.
The 2021
HXS differs from the "Short 90" Ell" in that it has only
1/4" hub at the mounting plate end and features a pipe spigot at
the other end. The vacuum pipe can be slid over and glued to the spigot
as the outside diameter of the spigot corresponds with the inside diameter
of the vacuum pipe.
Simply
glue to back of the mounting plate as you would any other fitting.
The 2021
is not included in kits, but is available from your dealer
Second
story inlet take-off from Attic to Basement drop.
A) For
confined wall space. Although not included in a kit, this special short
tee is available from your dealer for 2" x 4" and 2"x
3" stud walls.
B) If space
is available, use the fittings as shown in this diagram.
Both fittings
are included in kits.
Make sure
that the Main-to-Branch loop is always above and not below mainline
as dust and dirt will collect in the bottom of a loop.
