GENERAL NOTES

Important tips for safe & long-lasting operation of the one2clean:
• The SBR system is designed for the treatment of all household sewage. The introduction of other wastewater, such as
the wastewater from restaurants and/or business establishments, etc. is permitted if these were already known at the
time of design of the system and were taken into account.
• Biocides, materials with a toxic effect or materials that are not biologically compatible must not enter the system, as
these impede bacteria important for wastewater treatment and lead to biological process problems (detailed notes
follow on the next pages).
It is imperative that you follow the operating and maintenance instructions for compliance with the regulatory
requirements for cleaning. These instructions can be found on the following pages.
Furthermore, we ask that you carefully read and observe the following notes:
• The location of the control system for indoor installation must be a dry, well-ventilated room (basement or garage).
• If an outdoor control cabinet is used, this should be placed in as shaded place as possible to avoid overheating.
• At no time must the cabinet be covered, in particular its air vents, and that it is freely accessible for maintenance.
• There must be a permanent power supply to the one2clean. Ensure that the control cabinet is adequately fused (16
A) and the power supply is fitted with isolator switch for repair & maintenance. Additional electrical components &
consumers should not be using the same fuse as they can could power failure and interfere with one2clean operation.
