7. Recommended
For the secure and functional positioning of the solvent reservoirs, place them in the tray
of the Solvent Rack.
8. Keep the following in mind for NC pump operation and maintenance:
When the fluid components of the NC pump are filled with liquid and the solvent
reservoirs are located above the pump outlet during pump operation, the hydrostatic
pressure in the system may cause eluent to escape when you open a fluid connection in
the NC pump. Before you open a fluid connection, position the reservoirs below the
connection to be opened. Empty the solvents lines. If solvent shut off valves are installed
on the solvent lines, you can close the shut off valves instead.
4.3.2.2 Loading Pump
1. Prepare the solvent reservoirs as described in section 4.3.2.1 (→ page 63).
2. The solvent supply lines are connected to the loading pump at the factory. Connect the
solvent supply lines from the reservoirs and from the pump to the degassing module of
the Solvent Rack. For information about how to connect the tubing to the degasser, see
the Solvent Rack manual.
If a degasser is connected to the loading pump but is not used (degasser turned off),
change the flow path and connect the solvent reservoirs directly to the pump, instead. Use
the solvent supply line (1.0 mm I.D.) and solvent supply line filter with 10 µm PEEK frit
from the accessories kit of the NCS for the connection. To connect the components,
follow the steps in section 4.3.2.1.
