Repairing the Autosampler
Exchanging Internal Parts
Exchanging Internal Parts
WARNING The following procedures require opening the main cover of the
autosampler. Always ensure the autosampler is disconnected from the
line power when the main cover is removed. The security lever at the
power input socket prevents the autosampler cover from being taken
off when line power is still connected.
WARNING The power supply still uses some power, even if the power switch on
the front panel is turned off. To disconnect the autosampler from line
power, unplug the power cord.
WARNING When opening capillary or tube fittings solvents may leak out. 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.
NOTE The electronics of the autosampler will not allow operation when the top
cover and the top foam are removed. A safety light switch on the main board
will inhibit the operation of the autosampler. Always operate the autosampler
with the top foam and top covers in place.
CAUTION Internal components may be sensitive to electrostatic discharge (ESD).
Always use an ESD strap when handling internal components (see “Using the
ESD Strap” on page 105).
The procedures in this section describe how to exchange defective internal
parts. You must remove the autosampler from the stack in order to open the
main cover.
