Integral Fraction Collector FT (VF-F20-A) 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—Hydrostatic Pressure
Solvent may spill when you open the flow path during pump operation.
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 low-pressure 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 solvents lines. Refer to the Operating Manual for the
pump.
•
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 as
long as the power cord is connected. Repair work on the device while
the device is connected to power could lead to personal injury.
•
Always unplug the power cord before starting repair work inside the
