CAUTION! Risk of damage!
Inappropriate materials in the system can cause damage to the product.
• Never introduce solid substances, debris, ashes, garbage, sand, plaster, cement, lime,
mortar, fibrous materials, textiles, paper towels, diapers, cardboard, coarse paper, syn-
thetic resins, tar, kitchen waste, greases, oils, slaughterhouse waste, disposal of
slaughtered animals and animal waste (liquid manure, etc.), toxic, aggressive and cor-
rosive substances, such as heavy metals, biocides, pesticides, acids, bases, salts, clean-
ing agents and disinfectants, dish-washing or laundry detergents, and such which have
a high degree of foam formation or swimming-pool water.
If greasy sewage should accumulate, a grease trap is to be installed.
• Improper use and overstraining lead to material damage to the product.
• The maximum possible inflow must always be less than the volume flow of a pump at
the respective duty point.
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.
