Note for the operator
An explosive atmosphere can form in the supply
drum with concentrations of over 15% w/w and/or
high ambient and media temperatures. If a spark
jumps as the suction lance is approaching the
open opening of the supply drum, it could cause
this atmosphere to explode.
Therefore take appropriate measures, such as the
following:
–
Use an earthing cable to ensure that the suc‐
tion lance and storage tank have the same
potential just before inserting the suction lance
into the storage tank.
–
Use suction lances with a level switch with
explosion protection for Zone 0.
–
Only connect the ammonia water to the system
in its original drum or in an electrically con‐
ducting vessel.
1. Close the bottom stopcock on the metering vessel and con‐
nect the dilution water line.
2. Fill the dosing tank through the dilution water line up to the
maximum level - 120 l or 250 l marking, dependent on the
tank size.
3. Close the stopcock on the dilution water line.
4. Completely fill the test tank (empty ammonia water supply
drum) with rinsing water, e.g. condensate or deionised water.
