3.2. Installation
The Quick-Lock Mini system must always be installed along with a sliding camera. Always
ensure that the push rods are used in conjunction with a hexagonal pneumatic fitting to position
the lock (locking mechanism) in the vertex as far as possible (while remaining turnable).
• Grip the sleeve by inflating the packer balloon to a holding pressure of approximately 0.5 bar.
The holding pressure is correct when the sleeve is firmly held on the packer but is not
starting to expand.
• This prevents the sleeve from slipping off.
• The holding pressure of 0.5 bar may vary slightly depending on the compressed air unit, the
pipe nominal diameter and the packer. We recommend that you identify the correct pressure
for your system yourself.
• Now transport the packer with the Quick-Lock sleeve to the damaged area.
• Position the centre of the sleeve over the centre of the damage so that the damage is
located between the seals.
Positioning pressure
• Press the packer with a positioning pressure of approximately 2.0-2.5 bar so that the sleeve
expands and rests against the pipe wall.
Warning: When expanding, make sure the sleeve opens evenly. The sleeve opens more easily
if the metal overlap is lubricated.
• Apply pressure to the sleeve very slowly and intermittently and wait until it has reached full
expansion. The smaller the sleeve is, the more important the time is.
Reducing the pressure
• Deflate the packer balloon.
Application pressure
• Now apply an application pressure of 6.0 - 6.5 bar to make sure that the Quick-Lock-Mini
sleeve is completely compressed against the pipe wall. After this, release the pressure from
the packer balloon, if necessary, position the packer in the middle of the respective locks and
repeat the procedure.
Warning: In the case of downpipes, there is no counter pressure, so the applied pressure
should be reduced.
Deflation
• Deflate the packer balloon completely and remove the packer.
Inspection
• Using the camera, check the Quick-Lock Mini has been installed correctly. Pan around the
edges of the sleeve. The sleeve should now be fully pressed against the wall of the pipe.
3.3. Documentation
The repaired area must be documented when the inspection is successfully completed.
