Vacuum test
Perform a vacuum test only for Fillcontrol Auto 2PS.
Proceed as follows:
1 Close the ball valve (2) with the dirt trap (1) of the degassing
line. The second ball valve (3) remains open.
2 Generate a vacuum with the manual mode of the controller.
•
Press "Manual" on the controller's operator panel.
•
Use the "Back" toggle button to select "SE" system
degassing at the operator panel.
– The pump will start after a time delay of
approximately 50 seconds.
3 Use the "Back" toggle button to switch off "SE" system
degassing after the pump runs for 10 seconds.
•
Record the vacuum value displayed at the vacuum
gauge.
4 Observe the vacuum gauge (1) for approximately 10
minutes. The pressure must not change. If the pressure has
increased, check the device for leaks.
•
Check all screw fittings at the vacuum spray tube for
leaks.
•
Check the venting screws at the pumps for leaks.
•
Check the degassing valve at the vacuum spray tube for
leaks.
5 After the vacuum test has been concluded successfully, open
the ball valve of the degassing line.
6 If the controller displays the "Insufficient water" error
message, confirm this error message with "Quit".
The vacuum test is completed.
Note!
Repeat steps 2 to 4 until no further pressure rise is observed.
Note!
The obtainable vacuum corresponds to the saturation pressure at the existing water temperature.
– At 10 °C, a vacuum of approximately. -1 bar can be obtained.
