2.4 Arranging the Accessories
2.4.1 Connecting the Keyboard
730
The keyboard is to be con-
nected to the keyboard socket
on the rear side of the sample
changer. To disconnect press
the plug together slightly on
both sides.
2.4.2 Setting up the Rinsing Equipment
To mount the PTFE tubings to the pump inlets or outlets enlarge it
carefully using a pen or another appropriate tool. A piece of sand
paper facilitates grasping of the tubing.
The arrangement of the tubing depends on the rinsing equipment.
Rotating nozzle
Using a changer model with one pump per tower only, the rotating
nozzle (6.2740.000) is recommended for rinsing. The Teflon tubing
is then directly connected to the rinsing pump (pump 1). The dis-
tribution head may be dismounted in this case.
Place the rotating nozzle vertically in the titration head with the aid
of a SGJ14/12 mm sleeve.
