Warning
Attention!

Preparations
•
Approximately 175 ml of lye solution is needed to use the IAM. Make a 30% KOH or
NaOH solution and dilute this with 2% ethanol or colourless methylated sprit. The lye
solution must be at room temperature. Approximately 60 grams of CO
by 175 ml of lye solution.
•
To avoid pressure differences, the liquid levels in both tubes must be made equal using
the levelling barrel before taking the measurement.
The following must be carried out before the ICC-2000 can be used together with the IAM:
Method:
1. Close the needle valve (pos. 8),
2. Connect the IAM's hose (pos. 106) to the hose socket (pos. 40) on the ICC-2000.
3. Close the IAM's sealing tap (pos. 112),
4. Fill the leveller barrel (pos. 103) almost to the top with lye,
5. Open the IAM's sealing tap so that the IAM is filled,
6. Slide the leveller barrel upwards (13 cm above the IAM),
7. Add a small amount of lye to the leveller barrel so that it is 1/3 full (the level in the IAM is
approximately 3 cm above the sealing tap),
8. Close the sealing tap and lower and leveller barrel until it is on top of the bracket (pos.
101).

Always wear protective gloves and goggles. Lye may cause
serious damage if it comes into contact with your skin or
eyes. Remove lye immediately using a large quantity of
flowing water. Contact a doctor immediately.
Used lye should be disposed of according to the national
legal environmental and health regulations.
Refresh the lye in time.
