Hazard through heavy weights/Sturdiness of system parts
Depending on the version, the pre-assembled chamber parts weight about 40 - 60 kg, the chamber
covers 50 - 90 kg and the pumps 15 kg. The parts may only be lifted and installed by two people using
respective lifting gear, exercising due care and wearing protective equipment (e.g. safety shoes).
Health risk/Personal protective equipment
The wastewater system pumps wastewater free of sewage which can contain hazardous substances.
During all work on the system, care must be taken that there is no direct contact between the waste-
water or system parts soiled by it and eyes, mouth or skin. In the case of direct contact, the part of the
body affected must immediately be washed thoroughly and disinfected if necessary.
In addition, the atmosphere in the chamber system can present a health risk. For this reason, make
sure sufficient air exchange has taken place before entering the chamber, or that a respective (forced)
ventilation takes place during entry.
We recommend the use of a portable multi-gas warning unit with an optical and acoustic alarm.
Noise pollution / Sound protection
Noise must be expected during operation of the pump(s). This noise can be annoying, depending on
the installation situation. In as far as requirements are made on the maximum permissible volume,
appropriate measures must be taken on site to meet these requirements.
Generally speaking, structural sound protection must be observed in accordance with DIN 4109. This
affects acoustic insulation of the collecting tank, for example, as well as the complete pipework instal-
lation (inlet, venting, cable conduits and pressure pipes).
Switching the pump on/Putting it into operation
Before use, check the conditions on site. The correct use of the pump is the basic pre-condition for
explosion protection.
• Dry run or slurping operation must be excluded!
• The machine must never run dry or in slurping operation, impeller and pump housing must always
• Minimum immersion depths must be heeded!
• The pump must never be used when there are people in the water.
• The pump builds up a pumping pressure/excess pressure.
