proof. The parts may only be shipped by forward-
ing agents who have been instructed appropri-
ately.

section!
Storage
• Thoroughly clean all components and decontami-
nate, if necessary.
• Store in a dry and frost-proof location.
•

-
ping and falling over.

7.3. Recommissioning
Before recommissioning, the aeration system
must be cleaned of dust and contaminants. Dur-
ing operation and storage, the diaphragm is sub-
ject to natural wear and hence must be checked
for cracks and elasticity before installation. Sub-
sequently, the aeration system can be installed
according to the section “Installation”. After
installation, a function test must be performed
according to the section “Commissioning”.
