NOTICE
• The inlet pressure must not exceed 6 bar.
• The EWR does not work correctly at inlet pressures < 2 bar.
The outlet stagnation pressure can be set in increments of 0.2 bar within the
range 0.2 to 2.0 bar.
The maximum outlet stagnation pressure corresponds to the inlet pressure
minus 1.5 bar.
