Tubing System Installation

Important notes for installation!
1) The 90° inlet elbow may be installed only together with the mounting
bracket and the inlet valve. Anywhere else in the tubing system, 90°
sweep elbows and 45° elbows should be used. (Fig. A and B)

2) Tubes are cut straight so that the cutting line is not slanted. Use a miter
saw if possible. Cut edges can be fi nished with a knife (to remove burrs).
3) For tubing joints, use suitable PVC glue to make the fi ttings secure and
tight. Apply a thin and even layer of glue only to the end of the tube – not
to the sleeve. This will prevent the glue from overfl owing to the end face
of the tubing. Close the glue can carefully immediately after use and make
sure to have adequate ventilation during installation. Avoid inhaling glue
vapors. Insert the tube all the way into the sleeve while turning it at the
same time (Fig. C).

4) The inlet is made through the fi re wall according to Fig.fi gure E or by
using a 2" (50mm) diameter fi re cuff (Fig. D). Check the inlet with a fi re
authority.

Begin the main tube installation with the farthest inlet valve and place the
tubes temporarily at fi rst. Do not glue the joints yet until you have made
sure that the tubing routing is correct. The glue will dry quickly; therefore,
the joints have to be fi tted right after applying the glue.
When measuring the tubes, take into account that the tube goes appro-
ximately 2/3" (18mm) into the sleeve and approximately 7/8" (20mm) into
the extension tube.
The tubing system can also be installed in a fl oor that will be concrete
casted later on (Fig. F). In such cases, the low-voltage cable must be
protected by a conduit pipe. The conduit pipe should be attached to the
vacuum tube or the casting net. For the vacuum tube, the routing channel
has to be 2" wide (51mm). The ends of the vacuum tubes and the con-
duit pipes should be plugged before concrete casting.
