Diffuser and/or rubber sleeves must be stored facto ry-packed in a dark, dry, ventilated and dust-free storage space according to DIN 7716. Avoid frost, heat, UV/radiation, dust and working which can cause damage of diffuser and/ or packing.
Do not store outdoors! The storage of rubber parts until installation/starting operation should not exceed one year. At on-site delivery, al l rubber and plastic parts must be stored in their original packaging. Crates exposed to direct sunlight must be covered with tarpaulin to protect against UV-radiation. Maintenance: Regular maintenance on a yearly basis is mandatory. Inspect diffusers visually after emptying tanks and cleaning diffusers. Removing deposits wil l increase lifetime significantly. Formic acid cleaning works against scaling only. Flushing diffu sers at maximum short-term airflow will keep diffusers in good condition over a long period of t ime. Please refer to data sheets and O&M manuals for details. Membrane lifetime: More than 5 years in municipal waste water treatmen t plants, depending on waste water influent and operation condition.

Shutdown of operation is highly recommended for air flow rates lower than minimum rate.
Do not apply overload air flow rate (e.g. cleaning) for more than 10 minutes each day
Numbers are for guidance only. Operating diffusers at too high or too low an airflow rate may reduce l ifetime or performance. See Technical Report `Slit size for ae ration membranes ́ for details. 1 This is an exemplary concept for R¾ external threa d only.
