MaInTEnancE
This operation may be performed only by a qualified person. Before replacing a lamp, always
unplug the detector from power source by disconnecting main supply cable. Reconnect the
detector to the power source only after the cover is mounted back in place.
UV light is dangerous for your eyes. If the flow cell is installed in the detector, then the UV
light is shielded. When performing flow cell maintenance, it is very important to protect your
eyes with glasses that absorb UV light. In case of any service requiring dismantling of any part
covering optical unit and when the lamp is on, it is necessary to protect your eyes with glasses
that absorb UV light.
