Application limits
The unit is not designed for permanent operation!
The specified maximum volume flow applies for intermittent operation (S3 – 15 %/80 s,
i.e. max. 12 s operating time, min. 68 s idle time).
The unit may switch on a maximum of 45 times per hour per pump. The running time of the
pump may not exceed 12 s, including the run-on time (run-on time = pump running time
after the end of pumping water). The operating time and run-on time (if required) should
be set as short as possible.
The geodesic delivery head may not be more than 6.5 mWS.
WARNING! Risk of burns!
Depending on the operating status of the installation, the entire pump can become very
hot. Touching the pump can cause burns.
WARNING! Danger due to overpressure!
If the lowest suction head is more than 5 m, this will cause overpressure in the reservoir
should the installation malfunction. If this happens, there is a risk that the reservoir will
burst.
In case of malfunctions, the inlet must be blocked off immediately!
The intended use includes complying with these instructions.
Any other use is considered outside the intended use.
