Proceed as follows:
•
Connect the "DC" degassing lines in the "V" main volume flow of the facility system.
•
The device requires two "DC" degassing lines to the facility system.
–
One degassing line for the gas-rich water from the facility system
–
One degassing line for the degassed water back to the facility system.
•
Fit the degassing lines near the "EC" expansion line.
–
This ensures stable pressure conditions.
•
Install the device near the "MAG" expansion vessel.
–
This ensures pressure monitoring of the expansion vessel.
–
Set the "Magcontrol" operating mode at the device controller.
Note!
•
Ensure the integration with the "V" main flow volume. in particular in switching variants with hydraulic
switching points and return admixtures.
–
For switching and make-up variants, see chapter 6.4 "Switching and make-up variants" on page 15 .

6
"DC" degassing line (degassed water)
For water make-up, note the following conditions:
•
For a water make-up via a "BT" mains disconnect
receptacle, its bottom edge must be at least 1 m over
the "PU" device pump.
•
Close the connection of the "WC" make-up line when a
make-up line is not connected.
–
Adjust the "Levelcontrol" make-up variant at the
device controller.
•
Install at least one "ST" dirt trap with a mesh size ≤ 0.25 mm close upstream to the "CD" 2-ways motorized ball valve.
Note!
Avoid a device fault.
–
Ensure that manual water make-up to the facility system is possible.
Note!
Use a pressure reducer in the "WC" make-up line if the idle pressure exceeds 6 bar.
6.4
Switching and make-up variants
The device has two make-up variants:
•
Pressure-dependent "Magcontrol" make-up.
–
In a facility system with an expansion vessel.
•
Level-dependent "Levelcontrol" make-up.
–
In a facility system with a pressure maintenance station.
–
As supplied, the device is preset to "Levelcontrol" operating mode. If no pressure maintenance station is connected,
pressure-independent degassing takes place without automatic make-up, see chapter 7.4 "Starting Automatic mode"
on page 21 .
