Assembly and Commissioning

Assembly and Commissioning

1. Place the flat gasket on the system according to the bolt circle.

2. Place the sieve congruently over the flat seal.

3. Place the second flat gasket congruently on the screen.

4. Place the filling adapter on the flat gasket and align with the bolt circle.

5. Screw in and tighten screws with washers.

6. Screw the adsorber into the upper thread. For this purpose, oil the thread slightly beforehand.

7. To top up oil, open the side cap and fill oil into the system.

5. Screw the screw plug firmly onto the filling adapter.
6. Reassemble everything.







Risk and Hazard Analysis

1. Moist air flows into the Plant
Porous gaskets
Moist air can flow into the system at the porous points. The seals must be checked according to the maintenance schedule.

Screw plug damaged
Humid air flows through the open screw plug past the adsorber directly into the system. Rough or improper handling can damage the sealing cap, e.g. at the thread.

2. Filling adapter is damaged
Material resistance
BWhen selecting the filling adapter, the ambient and operating conditions should be considered. An aggressive environment or liquid in the container can damage the filling adapter.

Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise the filling adapter may be damaged.

Improper handling
Incorrect or improper handling can damage the filling adapter. Please pay attention to the recommended mounting.

3. Dirt particles get into the Plant
Sieve damaged
Rough handling or the use of tools can damage the sieve, so that it no longer provides protection.

Threads of the Adsorber and Attachments are damaged

4. Threads of the Adsorber and Attachments are damaged
When mounting the adsorber as well as the valve part on the system, the threads must be slightly wetted with oil. Failure to lubricate the threads can lead to rubbing of the individual threads and is no reason for complaint.




Maintenance Plan

1. Check Seals for Wear

Check    The flat gaskets supplied with the filling adapter must be checked for perfect condition. For this purpose the seals should be checked for brittleness.
Cycle    Annually
Measures    If damage is present, the seals should be replaced.

2. Check Sealing Cap for damage

Check    Check the sealing cap for damage, especially on the thread.
Cycle    Annually
Measures    If the sealing cap is damaged, it must be replaced.

3. Visual Inspection of the Filling Adapter

Check    Check the sealing cap for damage, especially on the thread.
Cycle    Annually
Measures    If the sealing cap is damaged, it must be replaced.

4. Replacing the Wearing Parts

Check    The wearing parts, in particular the sieve, the seals and the screw plug must be checked with regard to their condition.
Cycle    Every two years
Measures    Regardless of the result of the test, it is recommended to replace the wearing parts to ensure smooth operation.
