Handling
Assembly
Replace gas pressure spring
The model replaces the built-in gas pressure spring in the case of a defect.
Proceed as follows:
-
Unlock the ceramic washbasin and lock it again in the lowest position.
-
Disassemble the drain elbow from the ceramic washbasin.
-
Disassemble the cover plate of the concealed connection box and drain elbow from the odour trap.
-
The actuation unit is to be disassembled as follows:
Turn the rosette.
Turn the actuation button of the hydraulic cylinder.
Loosen the screws of the sleeve.
Turn the sleeve off the hydraulic cylinder.
-
Close the corner valves in the concealed connection box and then loosen the compression fitting (SW 19).
NOTICE!Possible water leak! Close corner valves.
-
Disassemble the ceramic washbasin and sound insulation panel.
-
CAUTION!
Risk of injury – The cover plate is fragile. Remove carefully.
Disassemble the caps and screws of the cover plate and take the cover plate out of the element.
-
Loosen and remove Allen screw (5 mm) on the head of the gas pressure spring.
-
Pivot the gas pressure spring sideways.
-
Push the bracket into the top position.
-
Place a support below the threaded bolts of the washbasin fixing material on-site to ensure that the bracket does not fall into the lowest position.
CAUTION!Risk of crushing! If the bracket is not secure, it may fall down.
-
Loosen the lower Allen screw (5 mm) of the gas pressure spring and disassemble by pushing the flexible drain elbow to the side.
-
Remove on-site support and lower the bracket slowly by hand.
-
Lift the gas pressure spring in the front wall upwards out of the guide.
-
Remove gas pressure spring from the front wall.
-
Insert a new gas pressure spring and reassemble all components.
Preparing gas pressure spring for disposal
WARNING!
Risk of injury due to high pressure
The gas is the gas pressure is highly pressurised. There is a risk of injury due to flying metal fragments and oil, if disposal is not carried out properly. Observe following safety measures implicitly for proper draining.
Before disassembling:
No person in the extended axis of the device. The piston rod cannot hit anyone in the case of an error.
Do not remove the ends.
Under no circumstances use a lathe.
Put on eye / face and clothing protection.
In case of doubt, please contact your Viega Service Center.
INFO!
The gas itself is harmless.
Draining gas and oil
The container needs to be drilled at two points to enable the disposal of the gas pressure spring without pressure and without oil. The drilling points X1 and X2 vary depending on the diameter of piston rod and cylinder.
Diameter (mm) piston rod / cylinder | X1 (mm) | X2 (mm) |
|---|---|---|
8/19; 8/22; 10/22 | 20 | 30 |
8/28; 10/28; 14/28 | 40 | 35 |
10/40; 14/40 | 40 | 55 |
-
Open up gas pressure spring.
DANGER!Protect eyes, face and body and cover drill hole before drilling.
-
Using a 2–3 mm drill, drill slowly at point X1 until gas escapes.
-
Due to the high internal pressure, metal fragments and oil can squirt out.
-
Using a 2–3 mm drill, drill slowly at point X2 until pressure drops and oil becomes accessible.
-
Pour out the oil into a suitable container.
-
Now, the piston rod can be easily moved by hand. If not, repeat procedure.
-
Saw through the metal cylinder, if necessary.
-
Disposal of the individual components can now take place.
Disposal
Separate the product and packaging materials (e. g. paper, metal, plastic or non-ferrous metals) and dispose of in accordance with valid national legal requirements.
