ProMinent DULCODOS Ammonia, Руководство по эксплуатации, Страница: 32 / 52

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.
As soon as the supply drum is empty, replace it with a full
original supply drum.
