MISE EN GARDE: Un mauvais alignement de la pompe sur le réservoir peut endommager le 
bouchon d'étanchéité sous vide. Pour éviter le risque de gel du capuchon d'étanchéité à vide, la fig-
ure 26 montre l'orientation de la pompe vers le réservoir.

Installing the LN Pump on the Discovery DSC

Installation of the LN Pump onto the Discovery DSC involves:

1

Removing the Discovery DSC covers

2

Mounting the cooling head

3

Connecting the heater cable

4

Replacing the covers

5

Connecting the cables and lines

This section provides the instructions for installing the LN Pump on the Discovery DSC. 

Remove the top cover on Discovery DSC 25, DSC 250, DSC 2500

If an Autosampler is present, it must be moved away from the cell by pressing the 

Lid Open/Close

 

 button on the user interface.

WARNING: Do not place your hands in the path of the Autosampler when it is in motion. Physi-
cal injury may occur. 

AVERTISSEMENT: Ne placez pas vos doigts sur le chemin de l'échantillonneur automatique 
lorsqu'il est en mouvement. Des blessures physiques peuvent se produire.
