Application limits
The specified maximum volume flow applies for intermittent operation (S3 – 60% / 60 s,
i.e. max. 36 s operating time, min. 24 s idle time).
The unit may switch on a maximum of 30 times per hour per pump. The running time of the
pump may not exceed 36 s, including the follow-up time (follow-up time = pump running
time after the end of pumping water). The operating time and follow-up time (if required)
should be set as short as possible.
Furthermore, the operating parameters should be observed in accordance with Table 5.2.
WARNING! Danger due to overpressure!
If the lowest inlet head is higher than 5 m, this will cause dangerous overpressure in the
reservoir in the event of a unit failure. If this happens, there will be a risk of the tank
bursting. In case of malfunctions, the inlet must be blocked off immediately.
WARNING! Risk of burns!
Depending on the operating status of the system, the entire pump can become very
hot.
Touching the pump can cause burns.
Correct use of the pump/installation also includes following these instructions.
Any use going over and beyond the intended use is considered to be improper.
