>
Safely collect escaping pumped media and dispose of in an
environmentally-friendly manner.
Caution
Material damage due to high temperatures of the pumped medium
>
Do not pump liquids with a temperature of more than 90 °C, otherwise
the impeller material will become attacked.
Caution
Material damage due to dry running
>
In case of a suction depth of more than 3 metres, fill prior to
commissioning.
ZUWA impeller pumps are
self-priming, thus, in case of a suction depth of up
to 3 metres, it is not necessary to fill the pump prior to commissioning.

To start the pump, switch on drive.
During the intake process, the pressure side must not be closed, otherwise
intake will not be possible

>
Do not block pressure side for more than a minute while the drive is
running.
Caution
Material damage due to dry running

Never allow the pump to run dry for more than one minute.
All ZUWA impeller pumps are suitable for continuous operation.
After extended periods of pump down time prior to commissioning, check that
the impeller wheel runs freely and that the pump starts. See also chapter
