4. OPERATION

The installation must be performed by a qualified professional.
Please, check each time before using, the electrical connections and the cables are not damaged. Check
before the installation whether the electrical connections are earthed according to the statutory regulations
and are installed. The pump is to be secured through a RCD circuit breaker with release current of 30 mA. is
technically correct, so this warranty is void. It must be ensured that the pump is sufficiently cooled during pro-
longed operation. If the suction height is greater than 4m or the suction length is more than 9m, please make
the suction line 1 1/4 „(about 32mm) or 1 1/2" (about 38mm) instead of 25mm.
It is not recommended to perform even cable extensions or any other technical modifications. The lines to the pump must
be installed always steadily rising. A transfer of mechanical loads or vibrations from the pump or to the pump must be
eliminated through appropriate actions (use of rubber buffers, braided hoses, line fixation, etc.). If the suction height is
greater than 4m or the suction length is greater than 9m, please make the suction line in 1 1/4" (approx. 32mm) or 1 1/2"
(approx. 38mm) instead of 25mm. Do not reduce the suction line. Please install at the end of the suction line always a
check valve, if necessary with floating inlet (at use of rainwater this is mandatory). All pipe/hose connections to and from
the pump must be sealed (e.g. Teflon tape or sealing cord -
line „as one piece" without any interruption in order to prevent and avoid leaks. check valve and test water pipes for leaks
by means of a pressure test for at least 24 hours. Is dirt expected in the pump, an effective pre-filter should be installed

before the pump inlet.
Start the pump. If necessary, the pump and the suction line must be refilled until a normal continuous operation has been
established. If the pump is used outdoors, it must be protected against direct sunlight (risk of overheating) and rain (risk of
short circuit).
