Central vacuum systems

The electric control line is installed in the following

way:

the electric cable coming out from the electrical

junction box, which is placed near the central unit,

is installed together with the tubing and is connected

from one backup box to the other.

Fix the sheath to the tubes using the suitable wire

clamps.

The backup boxes are connected by inserting the

ends of the electric sheath pre-inserted into the two

openings of the backup box.

Please notice: in order to allow future connection

to the binding screw and to the inlet valve insert the

electric cables for approx. 5 cm into the backup box

and in the electric junction box.
