Installation and commissioning
Normally, the Hg/hydride system is installed by the Analytik Jena customer service or
persons authorized by Analytik Jena together with the AAS device. If the Hg/hydride sys-
tem is delivered separately at a later time, you can also install it yourself.
When installing and commissioning the system, observe the information in the "Safety
instructions" section. Compliance with these safety instructions is a requirement for the
error-free installation and the proper functioning of your measuring station. Observe all
warnings and instructions that are attached to the device itself or displayed by the con-
trol and analysis program.
To ensure trouble-free operation, please make sure that the installation conditions are
observed. To do so, check the installation conditions specified in the manual for your
AAS device.
