1. Quick-Lock Mini system description
1.1. System description
The Quick-Lock Mini has been designed to the repair of damages in the nominal width
of DN 100 till DN 150. Length of the sleeves is 90 mm or 140 mm.
1.2. Suitability and materials used
The system is manufactured using V4A stainless steel grade 1.4404 (AISI 316L) and
EPDM compression seal.
These materials are extremely durable in municipal waste water. The suitability of the
materials for use in industrial or contaminated waste water is yet to be verified.
• Use the technical Data Sheet (see Appendix 1)
to choose the right and most suitable Quick-Lock Mini for your particular application.
• For more information on the suitability of the products please see Chapter
1.6 of the Quick-Lock Manual.

2. Use of Quick-Lock Mini
2.1. Preparation
2.1.1. Inspecting the pipe
Before using the Quick-Lock system, it is necessary to inspect the pipe/ducts due
to be repaired and verify whether repair using Quick-Lock is possible.
There must be at least one access point available via a manhole or an inspection
opening.
It is necessary to verify the possibility of transporting a packer with a sleeve into
the pipe/duct.
2.1.2. Cleaning and preparing the pipe based on the application
• The pipe to be repaired must always be cleaned with a high-pressure jet
before installing Quick-Lock.
• Hardened sedimentation, roots and protruding connecting pieces must be
removed with appropriate milling tools.
• The pipe should have no obstructions that may restrict movement.
• There must be no solids such as sand, gravel, hardened deposits or
waste water solids around the damaged area.
• Part 5 of DWA-M 143 prohibits works from being done in waste water,
which means the pipe section must be closed off. Depending on the amount of
water, bypassing may be necessary.
• In the case of high-pressure cleaning, do not use other cleaning equipment
since it may worsen the damage.
• The area to be repaired should be visually inspected and documented
after cleaning.

2.2. Preparing the Mini sleeve
Inspection
• Check the Quick-Lock Mini and the EPDM
rubber for visible damage.
Oil the sleeve
• Use a biodegradable oil.
• Push apart the metal overlap with
a screwdriver.
• Oil the metal overlap to ensure
that the sleeve will slide apart evenly.
• Oil the two locks.
• Wipe off excess oil from the inside
and outside of the sleeve.
Cutting the transport tapes (adhesive strips)
The adhesive tape prevents the sleeve from
opening during transport.
• Cut half-way through the adhesive tape
in the area of the metal overlap.
• Warning: If you cut right through the tapes,
there is a risk that the sleeve might unroll
when entering the pipe, thus restricting its
movement.
• Warning: If you do not cut the tapes at all
there is a risk that the sleeve might unroll
too suddenly during installation when the
tape tears, and break the return stop in
the gears.
Cut the adhesive tape half-way through

Applying talcum powder to the rubber EPDM
• For easier handling, sprinkle talcum powder
on the inside of the rubber.
• This makes it easier to slide the rubber
over the sleeve. It also reduces the friction
between the rubber and the steel sleeve
during expansion.
Centring the EPDM rubber
90 mm sleeve
• When using a 90 mm sleeve, the rubber is
usually trimmed.
• Use a sharp cutter knife or industrial
scissors.
• Cut along the marking seam.

7
Affixing the EPDM rubber
• To prevent displacement of the rubber EPDM
on the QL Mini during transportation to the da-
maged area, affix the seal on both sides of the
stainless steel sleeve and at the ends above
the locks with a drop of super glue.
• Warning: Under no circumstances should
the super glue drip onto the metal overlap,
otherwise it will not longer be possible for
the sleeve to expand.
• Warning: If the rubber is not properly
affixed, there is a risk that it might bunch
up at a constricted point in the pipe without
you noticing.

3.1. Positioning the Quick-Lock sleeve on the packer
Set packer to nominal width
• Set the adjustable chassis of the packer to
the nominal width of the host pipe. (See
also instructions “Offset packer with
adjustable chassis” 3.4, Appendix 4 of the
Quick-Lock Manual).
Positioning the sleeve on the packer
• Position the Quick-Lock sleeve flush on
the packer.
• Turn the Quick-Lock sleeve so that the
middle of the toothed strip is in the
12 o’clock position.
• Depending on which way you are looking,
the lock is in the 11 o’clock or the 1 o’clock
position.
• After installation, the lock is always at the
top, i.e in the 12 o’clock position.
To install the Quick-Lock Mini bendable sleeves
(90 mm), use our bendable Quick-Lock packer
in conjunction with the appropriate push rods
and sliding camera.

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.
