WARNING! Health hazard!
Because of the materials used, the pumps are not suitable for pumping potable water.
Contaminated sewage is a health hazard.
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%/120 s,
i.e. max. 18 s operating time, min. 102 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 18 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.
In addition, the operating parameters in accordance with Table 5.2 are to be observed.
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 dangerous 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.
Correct use of the pump/installation also includes following these instructions.
Any use over and beyond these is interpreted as incorrect use.
