Pre-gassing
Bubble breaker

These can be connected to the water connection and flushed via four 3-way ball valves below the
valve cabinet. The respective valves must also be opened here using the "Flush CO2 units" but-

Cleaning the high-pressure injection nozzles
The high-pressure injection nozzles can become clogged over time. This is particularly the case
with water containing a lot of lime. This can be recognized by different effects:
The overall effectiveness of the high-pressure injection diminishes.
The formation of foam after high-pressure injection is not uniform.
The nozzles must be removed and cleaned in this case.
