Maintenance and Repair
Autosampler
The power supplies still use some power, even if the power switch on the front
WA R N I N G
panel is turned off.
Repair work at the autosampler can lead to personal injuries, e.g. shock hazard,
when the autosampler cover is opened and the instrument is connected to power.

Exchanging Internal Parts
Some repairs may require exchange of defective internal parts. Exchange of
these parts requires removing the autosampler unit from the Agilent 1220
Infinity II LC; these repairs have to be done by trained service personal only.
Safety flap, flex board
It is strongly recommended that the exchange of the safety flap, and flex board
is done by Agilent-trained service personnel.
Transport assembly parts
The adjustment of the motors, and the tension on the drive belts are important
for correct operation of the transport assembly. It is strongly recommended
that exchange of drive belts, and the gripper assembly is done by
Agilent-trained service personnel. There are no other field-replaceable parts
in the transport assembly. If any other component is defective (flex board,
spindles, plastic parts) the complete unit must be exchanged.
