4 Repairing the Detector
Introduction into Repairing the Detector
Simple Repairs
The detector is designed for easy repair. The most frequent repairs such as
lamp change and flow cell change can be done from the front of the detector
with the detector in place in the system stack. These repairs are described in
“Simple Repairs” on page 101.
Exchanging Internal Parts
Some repairs may require exchange of defective internal parts. Exchange of
these parts requires removing the detector from the stack, removing the
covers, and disassembling the detector. The security lever at the power input
socket prevents that the detector cover is taken off when line power is still
connected. These repairs are described in “Exchanging Internal Parts” on
page 138.
WARNING
To prevent personal injury, the power cable must be removed from the instrument
before opening the detector cover. Do not connect the power cable to the detector
while the covers are removed.
WARNING
To prevent personal injury, be careful when getting in contact with sharp metal
areas.
WARNING
When working with solvents please observe appropriate safety procedures (for
example, goggles, safety gloves and protective clothing) as described in the
material handling and safety data sheet supplied by the solvent vendor, especially
when toxic or hazardous solvents are used.
