Push a length of tubing up into bottom of the elbow

on the inlet valve assembly. Piece together sections

of tubing without glue at fi rst to make sure things

fi t properly. Mark the connections so you can

re-assemble them the same way. Remember, the

tubing enters the fi tting approximately 3/4" (1.9cm).

Measure, cut, and de-burr tubing, and, using a 90

degree sweep elbow, slip-fi t the vertical tubing line to

the main horizontal line. To avoid potential clogging

problems when installing tubing and fi ttings:

• Make straight cuts on tubing (pipe/tubing
cutter works well).

• Remove burrs from ends of tubing.

• Be sure tubing fi ts against the shoulder of the
fi tting with no gaps.

• Glue only the outside edge of the tubing before
assembly into fi ttings.

Drop bottom of tubing through 2-1/4" (5.7cm) hole and

nail stud-mounting bracket assembly to stud. Make

sure the center of the inlet hole is at the correct height

above fl oor level and the tubing extends below the

sub-fl ooring. To prevent a nail or screw from

penetrating the vacuum tubing, install nail guards

on the sole or top plates adjacent to the tubing. See

“Installation Step Six: Install the tubing” and complete

tubing installation as much as possible. After the

walls are fi nished and painted, plaster guards can be

removed and inlet valves installed. The tubing system

may be completed at that time and the power unit

installed.

(Existing Home or New Construction)

Beginning at the inlet farthest from the power unit,

temporarily fasten tubing for the main trunk line into

position. Hint: Loop string or low-voltage wire from

a nail or overhead pipe, etc., to cradle the tubing —

holding it in position while you work.
