1. Introduction
The pre-condition for the safe and reliable use and defect-free
operation of the Vetter Flexible packer is to have a sound knowledge and to observe these operating instructions as well as the
information concerning safety.
DIN 7716 is to be observed with long-term storage.
In addition to this, the pertinent regulations concerning work protection and work safety as well as accident prevention regulations
are to be observed together with the recognized technological
regulations.
These operating instructions are to be regarded as part of the product and are to be kept together with the product during its life
cycle. If the product is passed on to another party then these operating instructions must accompany it.
1.1 Correct application according to
regulations
These operating instructions apply to the following Vetter Flexible packer:
9 Short packer with frame
9 Flexible packer with frame
9 Lateral packer
Vetter Flexible packers were developed for application in the eld
of sewer repair. They are used for repair work on local damage to
sewers and pipelines. They are also suitable for damage repair
using liners and stainless steel shells or for lamination repair. Flexible packers can, according to size, be used in pipelines having
diameters from 80 mm to 600 mm. Any other applications or uses
going beyond this do not comply with regulations.
Applications which do not comply to regulations for the Vetter
Flexible packer are:
9 Incorrect use, operation and maintenance of the Flexible pa-
cker
9 Operation of the Flexible packer using defective safety de-
vices or ination ttings which are incorrectly connected or
not fully functional.
9 Non-observance of the instructions contained in the opera-
ting instructions with respect to storage, operation and maintenance of the Flexible packer.
9 Insucient monitoring of accessory parts or parts subject to
wear.
9 Maintenance and repair work incorrectly carried out.

2. Safety instructions
Use of the Vetter Flexible packer is to be made under the precondition that there is a sound knowledge of the contents of the operating instructions and that the operating instructions are fully
observed.
2.1 General information
9 Before operation of the packer and its accessories, an inspec-
tion must be made to ensure it is complete and that all safety
measures are in place.
9 Select the correct packer size according to the pipe diameter.
9 Only use original Vetter accessories such as controllers, hoses
and ttings.
9 It is imperative that the required personal protective devices
be worn such as: protective clothing, gloves, helmet, face and
eye protection devices.
9 Bring the wheels of the mechanism to the correct position.
9 The packer must be protected against chemicals.
9 For the packer, the area in the pipe must be free of debris, dirt
and foreign bodies, e.g. broken fragments, sharp edged or
pointed objects etc.
9 Check to see if the packer is in the correct position in the
pipe.
9 Never exceed the packer operating pressure stipulated by the
manufacturer (max. 2.5 bar).
2.2 Information about the dangers
Any changes and reconstruction of packers, ination ttings and
ination hoses are not permitted. The operation of the Vetter Flexible packer is only permitted with original Vetter ination ttings
and ination hoses. Other parts obtained from another source can
compromise safety.
Flexible packers are made of a strong expandable material.
If the packers are expanded above the maximum permitted range
then this can cause bursting. No persons are allowed in the working area during reconstruction and repair work.

After positioning the packer it is to be ensured that nobody remains in the shaft or in front of the pipe during ination, reconstruction and deation work.
2.3 Warnings
Outside of the pipelines, Vetter Flexible packers are only to be inated to a maximum of 0.5 bar for the safety inspection.
All controllers are tted with safety valves that correspond to the
maximum permitted operating pressure of the packer.
If the maximum operating pressure of 2.5 bar is exceeded then
the safety valve will blow. The tolerance for opening and closing
of the safety valve must be maximum ± 10 %.
The set pressure is not allowed to be changed in any way.
Should the seal on the upper part of the valve be removed then
operation can no longer be guaranteed and the safety valve must
be exchanged. The permitted input pressure on the controller
(marked on the input coupling) must not be exceeded.
3. Preparations for operation
3.1 Inspection for completeness and safety
9 Inspection is made of the packer and the accessories.
9 The surface of the packer must not have any mechanical or
chemical damage: tears, forms of bubbles, show fabric lining.
9 The ination coupling as well as the wheel sets must function
perfectly.
9 The controller and the connection hoses must not have any
signs of damage.
9 The packer is to be cleaned after each period of use. In doing
this no aggressively acting cleaning agents are to be used.
3.2 Selection of packer size
9 Each packer is designed for a certain diameter. This size is sti-
pulated on the packer label.
9 Before operation, measure and check the pipe diameter clea-
rance to see if it is in the packer range.
9 The Flexible packer must not be used outside the specied
range.
3.3 Only use Vetter accessories
9 Carefully check the controller as well as the ination hoses to
see if they are clean because this is especially important for
perfect operation of the packer.
9 If there is any form of defect on the Flexible packer or its ac-
cessories then please contact the manufacturer.
