4 The wastewater treatment system's control unit
The plant is controlled at the operating unit on the controller's face side. The controller is used
to configure the operating parameters, view the operating statuses, query the plant parameters,
and program the operating times (this last by a specialist).
The controller presents two access levels with basic and advanced functions and parameters:
Operator menu (not password protected)
Service menu for specialists (password protected)
Use the small wastewater treatment plant only when it is in perfect working condition, only for its
intended purpose, and only with all due diligence to safety and risks as set down in the full Tech-
nical Documentation. The housing enclosing the controller for wastewater treatment plants may
not be opened. Please refer any questions to the manufacturer.
IMPORTANT
Keep the plant switched ON at all times!
If the plant is disconnected from the mains for more than 24
hours, it will be unable to clean the wastewater properly, if at
all.
Switch OFF the plant for maintenance and repair purposes
only.
Immediately after this work, switch the plant back ON.
