Installing Main Line
With inlet valves and branch vacuum lines installed,
proceed with the installation of the main vacuum
line. The
run should
be as short and
direct as
possible, and the tubing should be supported with
the pipe straps.
3.15 Start at the most distant inlet valve and work
back towards the power unit. Sweep tees should
be used to connect branch lines to the main line.
Be sure fittings are properly oriented so that air
flow is always back towards the power unit.
3.16 Use 45° elbows in the main or branch lines to
run tubing around obstructions. Branch lines should
run out of the side or top of the main vacuum
line;
never the bottom.

4. Make sure tubing is clear of obstructions.
5. Secure tubing to joists or studs for support.
Installing Electrical System
All low voltage wires should be taped to vacuum lines as they are installed. Leave approximately 6" of
wire at each point where connections are required and approximately 12" of wire at each valve opening.
Wire should be run from inlet and back to the Power Unit without any connections in between.
NEW HOUSE CONSTRUCTION
In new construction, installation is basically the same as in existing homes and overhead or under floors
are
equal
in ease
of installation.
However,
in all installations
it is advisable
to use
the
under
floor
installation if possible. The Inlet Valve Mounting Plates in new or open wall construction can be tacked
directly to the either side of the stud with nails or screws. (For Electrified inlet Valves see instructions
on pages 11-12.)
A plaster guard or plug should be placed over the valve opening in the mounting plate to prevent debris
from entering the vacuum lines during construction. The balance of the system may be installed after
the home is completed.
