Quick Test
As a quick test, it is possible to test the aerosol-tight buckets using the following process:
1.
Lubricate all seals lightly.
Always use the special grease 76003500 when lubricating the seals.
2.
Fill the bucket with approx. 10 ml of carbonated mineral water.
3.
Close the bucket as explained in the handling instructions.
4.
Shake the bucket vigorously using your hands.
This releases the carbonic acid gas
,
which is bound in the water, resulting in excess pressure.
Do not
apply pressure to the lid when doing so.
Leaks can be detected by escaping water or the sound of escaping gas.
Replace the seals if you detect any leaks. Then repeat the test.
5.
Dry the rotor, rotor cover and the cover seal.
CAUTION
Prior to each use, the seals in the bucket are to be inspected in order to assure
that they are correctly seated and are not worn or damaged.
Damaged seals are to be replaced immediately.
When loading the rotor, ensure that the rotor lid closes securely.
Damaged or clouded rotor covers are to be replaced immediately!
