9.1 Ext erior leak test
Check the following Servitec components for leaks:
• Pump
• Screw connections
• Degassing valves
Proceed as follows:
• Seal any leaks at the connections or replace the connections, if required.
• Seal leaking screw connections or replace, if required.
9.2 Cl eaning the dirt trap
The "ST" dirt trap in the "DC" degassing line must be cleaned no later than after
the continuous degassing time has elapsed. Check the dirt traps after every
filling action or extended operation.
1 "ST" dirt trap
1. Press "Stop" on the controller's operator panel.
– The Servitec is non-functioning and the "PU" pump is shut down.
2. Close the ball valve upstream of the "ST" (1) dirt trap.
3. Slowly unscrew the cap with the dirt trap insert at the dirt trap to release
any residual pressure in the pipeline section.
4. Pull the mesh from the cap and rinse it with clear water. Use a soft brush
for cleaning.
5. Re-insert the mesh into the cap, check the gasket for damage, and screw
the cap back into the housing of the "ST" (1) dirt trap.
6. Open the ball valve upstream of the "ST" (1) dirt trap.
7. Press "Auto" on the controller's operator panel.
– The Servitec is switched on and the "PU" pump is in operation.

Note!
Clean all other installed dirt traps (in the Fillset, for example).
9.3 Inspecting system degassing and make-up degassing
Inspect the "SE" system degassing followed by the "NE" make-up degassing.
Press "Manual" at the controller to switch to manual mode. The Auto LED at the
operator panel flashes to visually indicate that manual mode is active. Manually
activate or deactivate the "SE" system degassing and the "NE" make-up
degassing.
You should run at least ten cycles each in the "SE" and the "NE" modes. The gas
must be eliminated before the next cycle starts. Subsequently, check the
following conditions:
• With cold water, the "PI" vacuum gauge must eventually show a value of
approx. -1 bar.
• The "Insufficient water" message must not be displayed at the controller.
After the inspection is completed, reset the device to Automatic mode.
• "Next" and "Back" buttons
– Selecting "NE" or "SE".
• "Auto" button
– Return to Automatic mode.

9.5 Inspection
9.5.1 Pressure-bearing components
Comply with all applicable national regulations for the operation of pressure
equipment. De-pressurise all pressurised components prior to inspection (see
disassembly information).
9.5.2
Inspection prior to commissioning
In Germany, follow the Industrial Safety Regulation
[Betriebssicherheitsverordnung] Section 14 and Section 14 (3) No. 6 in particular.
This regulation demands an inspection prior to commissioning only for PS∙V >
50 bar x litres. This is not the case with this device. Customised systems with
special spray tubes may be affected, in which case the shipping documents will
contain a corresponding note.
