parable conditions, you should normally work with a freshly regenerated
suppressor unit.
Caution
The suppressor must never be switched over in a dry state, as there is a
risk of jamming. If the suppressor is in a dry state, it must be rinsed for
at least 5 minutes before it may be switched over.
Caution
In the case of reduced capacity or high backpressure, the suppressor
must be regenerated (see Chapter 5.11.3.2, page 74), cleaned (see
Chapter 5.11.3.3, page 76) or replaced (see Chapter 5.11.3.4, page
78).

5.11.3.2 Regenerating the suppressor
If the suppressor units are loaded for a longer period with certain heavy
metals (e.g. iron) or organic impurities, these can no longer be completely
removed with the standard regeneration solution. The capacity of the sup-
pressor units is consequently affected, which can result in reduced phos-
