7.6.1 Vacuum test
Perform a vacuum test only for Fillcontrol Auto 2PS.
Close the ball valve (2) with the dirt trap (1) of the degassing
line. The second ball valve (3) remains open.
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.
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.
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.
After the vacuum test has been concluded successfully, open
the ball valve of the degassing line.
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.
