WARNING
Risk of chemical burns due to acid and electrolyte solution return
Concentrated sulfuric acid is used in the Cl module 5100, phosphoric acid in the
TOC module 5100 and a slightly acidic electrolyte solution in the
S module 5100 coulometric.
A vacuum can be created in the analysis system when the combustion furnace is cooling.
This vacuum can lead to acid being drawn all the way into the auto-protection valve as-
sembly via connection hoses and lines.
¡
For the Cl module 5100: Only switch off the basic module and the gas supply when
the analysis system has cooled. The argon safety bypass on the auto-protection
valve assembly prevents a vacuum from being created during cooling for the chlo-
rine analysis branch. Alternatively: Remove the hose connection between the basic
module and the detection module before cooling.
¡
For the TOC module 5100 and the S module 5100 coulometric: Before shutting
down the basic module via the software, disconnection the hose connection to the
detection module.
}
Switch off the detection module via the power switch. Disconnect the power plug
from the power socket.
}
Shut off the gas supply.
}
Disconnect all connections on the rear of the detection module.
}
Seal the open gas connections with the ends of a short, fitting piece of hose to pre-
vent contamination during transport.
}
Remove loose components such as the absorber from the rear of the detection mod-
ule and package them individually.
}
If the detection module can be opened via the front door, remove all moving compo-
nents and package them individually. Observe the notes for individual detection
modules for this.
}
Carefully package the detection module and the accessories (cables, glass compo-
nents, hoses, clamps) in the original packaging.
}
Add a desiccant to the package to prevent moisture damage.
15.5.1 Notes for the transport of the Cl module 5100
WARNING
Risk of chemical burns
The concentrated sulfuric acid used as a drying agent and the acetic acid electrolyte so-
lution can cause severe chemical burns.
¡
Wear protective clothing when working on the sulfuric acid container and the mea-
suring cell.
¡
Observe all instructions and specifications in the safety data sheets.
}
Disconnect the electrodes (and the measuring cell) from the electrical connections on
the inside of the rear panel of the detection module.
}
Disconnect the measuring gas hose from the gas inlet tube/from the combined elec-
trode. Ensure that the seals of the PTFE screw connection are not lost during trans-
port.
