6.2.1 Preparing the analyzer (standard version)
The preparation of the analyzer includes the following steps:

Insert the open combustion tube

Insert the sulfuric acid container (vertically)

Prepare the chlorine module
The preparation of the electrolyte solution and the end point routine for the
measuring cell are described in the subsequent chapter (
→
"Preparing the measuring
cell", p. 59).
CAUTION
Risk of burns! Only install the combustion tube in the cold state!
When working with quartz wool avoid the creation of dust! Inhaled dust might cause
irritation to respiratory tracts.
NOTICE
Alkaline salts (hand perspiration) cause crystallizations in the quartz glass when
heating the combustion furnace which reduce the service life of the combustion tube.
Do not touch the combustion tube with your hands. Wear protective gloves. If
necessary, clean the combustion tube externally before installing it in the combustion
furnace (e.g. by wiping it with moist cellulose).
1. Exit the multiWin control software. Wait until the basic
device has cooled down.
2. Switch off the analyzer and the chlorine module using the
mains switch and pull the mains plug from the power outlet.
Cut the gas supply.
3. Remove the top cover and open the front doors.
4. If not yet done, tilt the combustion furnace into the vertical
installation position.
5. Carefully push a quartz wool plug into the open combustion
tube until it reaches the bottom.
