Adjust Pressure Maintaining Valve
• Vent filling valve and close afterwards (filling pressure gauge 0 bar)
• Start the compressor
• Observe filling pressure gauge
• When the opening pressure of the pressure maintaining valve is reached, the indicated filling
pressure increases within some seconds from 0 bar up to the adjusted opening pressure.
If the opening pressure does not reach a value between 150 and 180 bar, adjust the pressure
maintaining valve as follows:
Increase opening pressure:
• Vent filling valve (filling pressure 0 bar)
• Loosen clamp screw on the side
• Turn adjusting screw clockwise by using a suitable
slotted screwdriver
• Start compressor and check opening pressure, adjust if
necessary
• Tighten clamp screw on the side
• Check opening pressure again
Reduce opening pressure:
• Vent filling valve (filling pressure 0 bar)
• Loosen clamp screw on the side
• Turn adjusting screw anti-clockwise by using a suitable
slotted screwdriver
• Start compressor and check opening pressure, adjust if
necessary
• Tighten clamp screw on the side
• Check opening pressure again
Note
If the adjusted opening pressure of the pressure maintaining valve is higher than the final
pressure of the compressor, the final pressure safety valve blows off before pressure
maintaining valve opens (final pressure = 0 bar). When valve settings are not clear (e.g.
after disassembly / repair), start the adjustment with a low basic setting (turn adjusting
bolt 3 full turns in).
