1.2 Correct handling and usage
Depending on the application, Vetter leak sealers must only be
used with compressed air and only inated to the corresponding
pressure with original ination ttings.
They are exclusively used for sealing leaks on containers and
pipes.
Incorrect application of Vetter leak sealers includes the following:
9Incorrect use, operation or maintenance of leak sealers.
9Use of the leak sealers with defective safety devices or inati-
on ttings which have been either incorrectly installed or are
non-functional.
9Non-observance of the instructions contained in the opera-
ting instructions with respect to storage, operation and main-
tenance of the leak sealers.
9Insucient monitoring of accessory parts which are subject
to wear.
9Incorrectly carried out maintenance work.
The following also belong to correct application:
9Observance of all information contained in these operating
instructions.
9Compliance to the periods for maintenance and care contai-
ned in the Chapter“Maintenance and Care”.
2. Safety instructions
The use of Vetter Leak Sealers is made under the precondition that
there is a knowledge of this application and that the operating
instructions are observed.
2.1 General information
The observance of all pertinent regulations with respect to work
protection, safety and accident prevention (e.g. DGUV) as well as
generally recognized technological regulations is a precondition.
Leak sealers must be tested before application to see whether
they are resistant against hazardous materials. For this, refer to the
resistance chart!
The PVC acid protection cover for the leak sealing bag oers incre-
ased protection against acid spray.
Observe the pertinent regulations concerning handling with dan-
gerous liquids.
Protection equipment, such as protection clothing, gloves, hel-
met, face and eye protection, breathing protection and inherent
protection, are to be used onsite depending on the degree of
danger and the situation.

2.2 Information concerning the dangers
Danger of explosion! If there are inammable liquid or gas leaks it
is imperative that sparks be avoided by xtures and ttings.
Vetter Leak Sealers must only be lled when in the correctly ten-
sioned condition. Only ll the leak sealers until the leak is sealed
(max. operating pressure 1.5 bar and 12 bar). Any additional lling
of the leak sealer can damage the pipe or the tank by built up
pressures
A leak in a tank or container is a weak point. Therefore avoid any
additional damage by lling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the ma-
ximum permissible operating pressure.
2.3 Warning information
The leak sealers and the accessories are to be inspected for per-
fect condition before and after use. Damaged seals or seals and
accessories which are functionally limited present a source of dan-
ger and must not be used!
All controllers are equipped with a safety valve that corresponds
to the maximum permitted operation pressure for leak sealers.
These safety valves will blow when the maximum operating pres-
sure is exceeded.
The tolerance for the opening and closing of the safety valves
must be a maximum of ± 10 %. The set pressure must not be chan-
ged. Should the seal on the upper part of the valve be removed
then safe operation can no longer be guaranteed. The safety valve
must be exchanged. The permitted input pressure at the control-
ler must not be exceeded (marked on the input coupling).
Before application of the leak sealer, cover sharp edges and/or
pointed positions in the area of the leak by using dimensioned
sealing plates. In doing this you avoid damage to the leak sealers
as well as the unintended escape of dangerous liquids and gases.

3. Operation of the Leak Sealers
This chapter gives you information about which sources of com-
pressed air you are able to use with Vetter leak sealers.
When using leak sealers observe the
corresponding pressure stage.
3.1 Operation with controllers, ination hose and
compressed air bottle
As an example the following pictures present
the sequence of events for leak sealing
bags 1.5 bar. Corresponding leak sealers
and accessories must be used for other
pressures and other sources of air.
Before ination, the leak sealing bags
must be correctly and safely tensioned
with tension belts on the leak position.
To do this, refer to Chapter 4.3“Handling the tension rat-
chet”.
