Danger! NEVER use 3% chlorine bleach together with 5% hydrochloric acid (Risk of the formation of chlorine gas).

The chemicals used, in particular the chlorine bleach, are not allowed to be mixed or come into contact with other chemicals (Risk of the formation of chlorine gas).

Take suitable protective measures for the chemicals used. If necessary wear personal safety equipment (e. g. gloves and safety glasses).

Important note: Pay attention to the applicable safety data sheets, warning instructions

on the packaging and containers, and the applicable health and safety regulations. Observe the local regulations and protect the environment on the disposal of chemicals. Only clean the FILTRATION PROBE sc in a suitable tray. Pay attention to all hazard and safety instructions in the operating instructions for the analysis instrument and the FILTRATION PROBE sc.

1. Take the FILTRATION PROBE sc out of the tank; during this process pay attention to the installation instructions for the fastening system used.

2. Place the FILTRATION PROBE sc in the tray provided.

3. Remove the filter elements (see Figure 2 Removing the filter elements on page 5) and

store them so they remain moist.

4. Use 3% chlorine bleach (e. g: LCW811, diluted 1:3 with water) OR 5% hydrochloric acid as the cleaning solution.

5. Fill a container with cleaning solution and place the container near the FILTRATION PROBE sc.
