Chapter 2: Application limits
WARNING! The pump is not suitable for pumping inflammable or dangerous liquids!
WARNING! Avoid dry operation of the pump strictly!
Do not pump the water from a garden lake or swimming pool when persons, living animals are
staying in it!
For the proper operation of the pump, it is essential that you observe the basic precautions.
Protect the pump (e.g. in shafts) from vapour condensation; provide proper ventilation. The
vapour got into the motor space or switchbox may result in early failure of the pump. It is
important that the device is installed in a well-covered place, by which you protect it from
direct sunlight and rainwater. The too high ambient temperature may result in frequent switch-
on/ switch-off of the pump. Provide for winterproofing as well. Frozen liquid may result in the
breakdown of the pump and the parts found in it.

Chapter 3: Start-up, usage
DANGER! Risk of electric shock! Perform each operation of pump installation
only after having the mains cable disconnected!
DANGER! Risk of electric shock! The person responsible for the installation
should ascertain of whether the electrical network is equipped with efficient
earthing cable in accordance with the current norms!
The pumps are single-phase devices, equipped with 2+earthed wall plug at the end of the
mains connection cables; in this case the earthing is achieved when the plug is connected to
the socket.
The pump should be installed in each case in horizontal arrangement in optimum proximity to the place
of water withdrawal. If the distance measured vertically between the water level of the well and the connection
of the pump is more than 9 m (for certain types 8 m), then the water can also be withdrawn from a place deeper
by 1-2 m if the pump is installed in a shaft formed in the vicinity of the well.
