Aligning the locking gear strip
It is a good habit to always position the sleeve on the packer with the ends of the toothed strips facing the
same direction.
The sleeves would be regularly aligned in the pipe, especially when multiple sleeves are installed.
Turning the toothed strip upwards, to the 11:00 or 1:00 position

Turn the QuickLock sleeve so that the middle
of the toothed strip is in the 12:00 position.

Depending on which way you look at it, the
locking gear will be in the 11:00 or 1:00
position.

After installation, the locking gear will always
end at the top, in the 12:00 position.
Turning the locking gear to the 12:00 position

Depending on the design of the camera or the
transfer bar, it may be necessary to position the sleeve on the packer
with the locking gear in the 12:00 position, especially when installing
in a series and where movement is restricted. This prevents the
transfer bar from catching in a previously installed sleeve.

It can also be preferable during serial installation if the view through
the transfer bar is impaired by the locks on a sleeve that has already
been installed.

After installation, the locking gears will be in the 11:00 or 1:00
position.

If the QuickLock sleeve is positioned on the packer with the lock in
the 12:00 position, the weight is balanced.

This makes it easier to transport, especially in narrow pipes. It is also
reduces the risk of the packer tipping over in the pipe.
2.5.2.6.
Charging Device to hold position in place
The charging device is used to inflate the packer to a holding pressure
which keeps the sleeve from shifting.
To be done outside of the
manhole.

Attach the charging device to the air hose.

Position the sleeve on the front of the packer.

Connect the charging device directly to the packer with the
sleeve and wheels already in place.

Inflate the packer to a holding pressure of approx. 8 psi, or
enough to hold the sleeve in place on the packer securely.
This holding pressure may vary from packer to packer,
therefore it is the user’s responsibility to safely secure onto
packer.

The holding pressure is correct when the sleeve is firmly held
on the packer but does not start to open.

When not using a camera/tractor : Proceed to next step with
the charging device still attached.

When using a camera/tractor : Close the valve on the packer
and disconnect/remove the charging device.
