Integral Fraction Collector FT (VF-F20-A) Operating Manual Page 99
CAUTION — High Luminosity of LED
The high luminosity produced by the LED illuminating the inside of the
device can be harmful to the eyes.
•
Do not look directly into the light produced by the LED.
•
Do not use light-focusing instruments for viewing the light beam.
NOTICE
Pay attention also to the following guidelines:
•
Keep the device doors closed during the fraction collection
processing. If the doors are opened during processing, the fraction
collection processing is interrupted (without setting collection mode
OFF). An acoustic signal alerts that the doors are open. The device
stops the current movement of the needle arm and carousel, with
fraction collection valve switched to waste position as well. If the
doors are not closed within two minutes, then the sequence will stop
too. If the doors are closed within two minutes, the fraction
collection processing will continue by following the right moment
collection requirement from the system.
•
When operating the chromatography system, always set the lower
pressure limit for the pump. This prevents damage resulting from
leakage or from running the pump dry.
•
If there is evidence of leakage in the device, turn off the pump flow
and remedy the situation immediately.
•
Always verify that the fraction collector is turned on before the
pump flow is on and pressure builds up. If the device is turned off,
for example, after a power failure, stop the pump flow and wait until
the pressure is down to zero before turning on the device other
modules again.
