1.3.2 Disclaimer
1.3.3 Safety precautions
1.3.4 Service and repairs
None of the instrument’s components can be serviced by the user. Only personnel from Hach
Lange or its approved representative(s) is (are) authorized to attempt repairs to the system and
only components formally approved by the manufacturer should be used. Any attempt at
repairing the instrument in contravention of these principles could cause damage to the
instrument and corporal injury to the person carrying out the repair. It renders the warranty null
and void and could compromise the correct working of the instrument and the electrical integrity
or the CE compliance of the instrument.
If you have any problems with installation, starting, or using the instrument please contact the
company that sold it to you. If this is not possible, or if the results of this approach are not
satisfactory, please contact the manufacturer’s Customer Service.
1.3.5 Class 1 LASER
A Class 1 LASER is installed in this instrument. Class 1 LASERS are products where the
radiant power of the LASER beam accessible (the accessible emission) is always below the
Maximum Permissible Exposure value. Therefore, for Class 1 LASERS the output power is
below the level at which it is believed eye damage will occur. Exposure to the beam of a Class 1
LASER will not result in eye injury. Class 1 LASERS may therefore be considered safe.
However, Class 1 LASER products may contain LASER systems of a higher Class but there are
adequate engineering control measures to ensure that access to the beam is not reasonably
likely.
This Class 1 Laser product complies with 21 CFR Chapter 1, sub-chapter J. It is evaluated and
tested in accordance with EN 61010-1, Safety Requirements for Electrical Equipment for
Measurement and Control and Laboratory Use and IEC/EN 60825-1, Safety of Laser Products.
CAUTION
The manufacturer is not responsible for damages resulting from misapplication or misuse of
this product and rejects the regulation of such damages, including direct, indirect and
consequential damages, and in full accordance with applicable law. The user is solely
responsible for the identification of critical applications and risks and taking appropriate
measures to protect processes during a possible equipment malfunction.
DANGER
Risk of finger trapping.
A silicon insert is located on the transparent front door to assist in lifting and
lowering the door when adding or removing packages for analysis. Under no
circumstances must this silicon insert be removed.
WARNING
Electrical danger and fire hazard. Only use the supplied power cable. Only qualified experts
may perform the tasks detailed in the installation section of this manual, while adhering to all
locally valid safety regulations.
WARNING
Removable power cables must not be replaced with inadequately dimensioned power cables.

General Information
1.3.6 Use of antifoam
Antifoam is injected into the sample as part of the measurement process. Once a sample has
completed the measurement process it will therefore contain a small amount of antifoam. After
measurement, ensure the sample is disposed of in a sink (or similar) to avoid any risk of
ingestion. Refer also to the material safety data sheet (MSDS) Silicon antifoam (part number
33156) on page 69 for additional antifoam safety information.
1.3.7 CFL backlight
The CFL (compact florescent light) used for backlighting the screen display contains a small
amount of mercury. Please dispose of any used CFL’s in accordance with local, state or federal
laws concerning the disposal of products containing mercury.

2.5 Operation overview
1. Piercing
The reference volume is filled with the purge gas and the whole of the gas sampling path is fully
purged. The purge stops when the rubber seal of the piercing device contacts the top of the
package. Once the package is pierced, a pump injects an antifoam solution into the headspace.
2. Oxygen in headspace and CO2
The pressure is measured, then the regulating valve is opened and the gas contained in the
headspace flows over the O2and the CO2sensors at a given rate. The quantity of O2in the
headspace is obtained by integrating the volumes of O2leaving the package per unit of time.
The temperature is measured and combined with the pressure to calculate the CO2P/T value.
3. Liquid analysis (O2)
The gas flow is stopped and the ultrasonic sonotrode is activated. The regulating valve is then
opened and the gas escaping the liquid mixes with the gas of the headspace. The O2signal is
an exponential function to which coefficients can be included and the total O2contained in the
bottle is calculated by integrating this function.
Note: For faster measurements, the liquid analysis step can be skipped and the O2value calculated from
the headspace by setting specific parameters for the package (see Package parameters on page 35 for
additional details).
4. Headspace volume
At the end of the run, the gas flow is stopped and the valve is opened. The gas of the reference
volume expands in the headspace and the pressure reaches a new value. The headspace
volume is calculated with the ideal gas law principle.
5. End of measurement
The piercing head assembly is lifted out of the package. A short burst of gas purges the gas
sampling path to flush out any residual liquid or foam. The system returns to the standby mode
where the sensors are kept under a slight purge gas flow.
The mains power switch is located at the rear left of the instrument (No. 2 in Figure 3 on
page 16). To switch the instrument on and off, press the rocker switch to the
required position: “O” for Off and “I” for On.
The measurement button is located at the front right of the instrument (No. 5 in Figure 2
on page 15). Press this button to start a package measurement.
