Operating Manual
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. See Emptying the Solvent Lines
( } page 171) .
• Retighten the reservoir caps.
CAUTION—Electric Shock or Damage to the Device
After the power to the device is turned off, the device is still energized

• Always unplug the power cord before starting repair work inside the
