Operating Instructions HYGROPHIL® H 4230-12 BA 060207
Set the pressure at the compressed air conditioner's reducing valve to a
minimum of 2 bar to begin with and start measuring.
The proportional valve adjusts the air flow rate to the correct value in line
with the pressure in the customer system and the flow relationships.
If the value of 2 bar set for the pressure is not sufficient to generate the
necessary gas flow rate and the message „FLOW TOO LOW" is output,
increase the pressure to a maximum of 5 bar.
About an hour after starting up the system, check again whether errors
are displayed and make any corrections that are necessary.
