7.
Allow the adhesive to cure for at least 12 hours before carrying out
the leak test.
Installed chlorine input with threaded connection
6.3.2 Chlorine output (vacuum line)
Pipes made of PVC-U must be used for the vacuum lines. The pipe with
the nominal diameter of the vacuum connection should be chosen for
short distances. A larger pipe should be used for longer distances. If
several devices are connected to a line, the line must be calculated for
the entire chlorine flow.
The following nominal diameters are recommended for the vacuum line
(pressure drop of a maximum of 25 mbar, calculated at 0.9 bar with
4x90° angles):
If necessary, a greater nominal diameter can be installed for longer
distances and for shorter sections just in front of or after the devices a
connection with the nominal diameter of the devices can be selected:

Installing the vacuum line
Precondition for action:
The chlorine input of the vacuum regulator is installed.
The vacuum line is secured with a sufficient number of pipe clamps
and meets with the output of the vacuum regulator without tension.
All the components are clean and dry.
The transport protection at the output of the vacuum regulator has
been removed.
Perform the following working steps:
1.
Cut the PVC pipe at a right angle. Make a bevel on the outside of the
pipe (approx. 3 mm x 20°).
2.
Clean the pipe and the sleeve with the cleaning agent recom-
mended by the manufacturer of the adhesive.
3.
Glue the pipe in the connection. When doing so, follow the instruc-
tions for the PVC adhesive.

4.
Install the connection on the device. Make sure that the O-ring is
fitted.
5.
Tighten the union nut by hand.
6.
Allow the adhesive to cure for at least 3 hours before carrying out
the leak test.
Installed vacuum line.
If the pressure gauge on the inlet valve is pointing in the
wrong direction after installation of the chlorine supply, the
pressure gauge can be attached to the opposite side. For this,
exchange the pressure gauge and threaded plug. They are
installed with PTFE strips.
