Creating dead volume free capillary connections
To create dead volume free capillary connections, proceed as follows:
1 Slide the pressure screw over the capillary. Ensure that the capillary
protrudes 1–2 mm from the tip of the pressure screw.
2 Plug the capillary all the way into the connection or coupling until
the stop.
3 Only then start turning the pressure screw, while keeping the capil-
lary pressed in space.
Colored sleeves for PEEK capillaries
The enclosed set of varicolored sleeves for PEEK capillaries (6.2251.000)
serves to easily differentiate the various flows of liquid in the system
through color coding. Each capillary leading a given liquid (e. g. eluent)
can be highlighted with sleeves of the same color.
To highlight a capillary, proceed as follows:
1 Slide a sleeve of a selected color over a capillary an move it to an
easily visible position.
If the capillary heats up, the sleeve shrinks and adapts to the form of
the capillary.

3.6.1 Transport locking screws
To avoid damage to the high pressure pump and the vacuum pump dur-
ing transport, the pumps are secured with transport locking screws.
Remove these transport locking screws before the initial start-up.
Removing transport locking screws
1 Remove all of the transport locking screws with the 4 mm hexagon
key (6.2621.030) and keep them in a safe place.
