Quick test
As a quick test, it is possible to test the aerosol-tight beaker and fixed-angle rotors using the following
process:
1.
Lubricate all seals lightly.
Always use the special grease 76003500 when lubricating the seals 76003500!
2.
Fill the bucket or the rotor with approx. 10 ml of carbonated mineral water.
3.
Close the bucket or the rotor as explained in the handling instructions.
4.
Shake the bucket or the rotor 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.
Aerosol-tight Closure with ClickSeal
1. If necessary, grease the lid joint before closing the lid. Use grease 76003500 for this.
2. Raise the latch.
The cap can now be easily placed on the bucket.
Figure 5-4.
Bucket with open lid
3. Lower the latch to close the bucket aerosol-tight; be sure the latch clicks into place.
CAUTION
Prior to each use, the seals in the rotors 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.
Replacement seals are supplied with the rotors and can also be re-ordered as a spare parts
set 75003626.
When loading the rotor, ensure that the rotor lid closes securely.
Damaged or clouded rotor covers are to be replaced immediately.
