If a faulty seal is noted while the decomposition vessel is being filled with oxygen
(loud hissing noise), the O
2
seal washer on the filling piston must be replaced.
Faulty seal during the filling process may also result from the decomposition vessel
not being fitted snugly in place. Before checking the seal, make sure the decompo-
sition vessel is snugly in place. (Maintenance menu 2 ILOO )
You can remove an old badly split seal from the piston with tweezers.
To install a new seal, place it in the depression of the decomposition vessel (the
seal surface). Now suspend the decomposition vessel into the filling head of the
measuring cell cover and check to make sure it is properly positioned.
In the Maintenance menu, activate the item: 2 ILOO
The seal washer is now located on the piston capillary.
At the end of the filling process, remove the decomposition vessel from the filling
head and release the pressure on it manually.
