Introduction & Handling Rules for Cassettes and/or Diffuser Tubes
•When replacing the cassette or/and the diffuser tubes MICRODYN-NADIR strongly
recommends reading this technical instruction carefully and exactly following the instructions.
•Please note the safety and storage conditions described above and in the BIO-CEL®operation and
maintenance manual.
•In case of diffuser change, make sure to keep the membranes of the cassette wet.
•In case of cassette change please note, that once the membranes got wet, it must not dry out again.
•Make sure that nothing can potentially cause damage to the membranes or diffuser tubes during
assembly and installation.
•The diffuser tubes of the BIO-CEL®modules are developed and adjusted for the operation of the
modules. Therefore, in case of a necessary replacement of the diffuser tubes, the original diffuser
tubes supplied by MICRODYN-NADIR must be used. Other diffuser tubes may not ensure a proper
operation and can cause irreversible module damage.
Please note that improper handling and installation of the diffuser tubes can cause incorrect aeration
of the BIO-CEL®modules, which can again lead to major damages of the whole module.
In case of any questions please contact your responsible MICRODYN-NADIR sales contact.
