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.
Warning
In order to avoid damage to the pumps, the transport locking screws
must be remounted each time the instrument undergoes major trans-
port.
3.6.2 Leak sensor
The leak sensor detects escaping liquid which collects in the base tray of
the instrument.
For the leak sensor to function correctly, the following preconditions must
be met:
￭ The leak sensor connector plug (5-2) is plugged into the Leak Sensor
socket.
￭ The instrument is switched on.
￭ In the software, the leak sensor is set to active.
