1. Introduction and Handling Rules for Diffusor Tubes
When replacing the diffusor tubes MICRODYN-NADIR strongly recommends reading this
manual carefully and exactly following the instructions.
The diffusor 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 diffusor tubes, the original diffusor
tubes supplied by MICRODYN-NADIR must be used. Other diffusor tubes may not ensure a proper
operation and can cause irreversible module damage.
Make sure that nothing can potentially cause damage to the diffusor tubes during assembly and
installation.
Please note that improper handling and installation of the diffusor tubes can cause incorrect aera-
tion 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 sales engineer.
Please note our storage conditions in the BIO-CEL operation and maintenance manual. Additional-
ly the diffusors have to be protected against direct sunlight. After assembling immediately install the
membrane cassettes or cover the diffusor frame to protect against sunlight.
Module/cassette disassembling please note our assembling instruction document.
Cassette storage during the operation please note our recommendation for the preservation of
used modules (see our BIO-CEL®user manual, chapter “module maintenance”).
