Proceed as follows:
• Connect the "DC" degassing lines in the "V" main volume flow of the plant system.
• The device requires two "DC" degassing lines to the plant system.
– One degassing line for the gas-rich water from the plant system
– One degassing line for the degassed water back to the plant system.
• Install the degassing lines near the "EC" expansion line.
– You ensure stable pressure conditions.
• Install the device near the "MAG" diaphragm expansion tank.
– You ensure pressure monitoring of the diaphragm expansion tank.
– Set the "Magcontrol" operating mode at the device controller.
Ensure the integration with the "V“ main flow volume. in particular in switching variants with hydraulic switching
