PUTTING INTO OPERATION
■ Nobody must be in the water while the pump is
running.
■ The pump must only be operated in the performance
range indicated on the type plate.
■ Dry-running - i.e. operating the pump without
discharging water is to be avoided since the
absence of water may cause the pump to run hot.
This may cause considerable damage on the device.
■ Please make sure that the electrical plug
connections are in flood-proof area.
■ As long as the device is connected to the electrical
mains, one must never reach with one’s hands into
the opening of the pump.
■ Please inspect the pump visually prior to each use.
■ This applies in particular to the mains connection
line and the mains plug. Make sure that all screws
are firmly tightened, and verify the perfect condition
of all connection. A damaged pump must not be
used. In any case of damage, the pump has to be
inspected by qualified service staff. Each time the
pump is put into operation, please make sure that
the pump is set up securely and firmly standing.

screws located at the bottom of the pump. To avoid
any hazard, any further disassembly as well as
the replacement of parts must only be done by the
manufacturer or a by an authorised service provider.

below the freezing point of the liquid. Please store
the pump in a dry, frost-protected place.
■ In the case of malfuntion, you should first of all
