Maintenance Contract
The following maintenance work on the device may only be per-
formed by the manufacturer or a company authorized by the
manufacturer and is covered by a separate maintenance con-
tract:
• Opening the device or removing housing parts.
What is to be done if the degasser
leaks?
If the degasser leaks, solvent can reach the motor and from
there reach the degasser exhaust and flow out. In this case, the
automatic pump control will switch the device off.
• Inform the Technical Support of the manufacturer.
Tightening the Screw Fittings
1. If there is a leak at the screw fitting of the solvent tube, care-
fully tighten the screw fitting.
2. If it still leaks, loosen and check the screw fitting.
3. If no damage or deformation is visible at the seal ring and at
the screw fitting, repeat step 1.
4. If it still leaks, replace the screw fitting and seal ring.
