Vacuum spray degassing — 20.05.2019
English — 15
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.
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 .
6.3.3.1 Make-up line
1 "ST" dirt trap
2 "BT" system separator vessel
3 "WC" make-up line
4 Device
5 "DC" degassing line (gas-rich water)
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 .
