Operating Manual
CAUTION—Spraying Solvent
Solvents can spray when under high pressure.
•
Stop the pump flow prior to opening the flow path.
•
Wait until the system pressure is down to zero.
•
When opening the flow path, wear appropriate protective
equipment.
CAUTION—Hot Surfaces
Surfaces inside the device may become hot during operation. Touching
hot parts might cause burns.
Allow hot surfaces to cool down before starting replacement or
maintenance procedures.
CAUTION—Hydrostatic Pressure
Solvent may spill when you open the flow path. This is due to hydrostatic
pressure in the system when the solvent reservoirs are located above
the pump outlet. Before you loosen a connection in the flow path:
•
Turn off the pump flow and wait until the system pressure is down
to zero.
•
Unscrew the caps of the solvent reservoirs and remove the solvent
lines together with the caps from the reservoirs.
•
Empty the solvent lines. Refer to the
Operating Manual
for the
pump.
•
Retighten the reservoir caps.
CAUTION—UV Radiation
The deuterium lamp emits UV radiation that is harmful to eyes and skin.
Do not look and do not reach into the flow cell opening while no flow
cell or diagnostic cell is installed and the UV lamp is turned on.
