Clear the outlet line before use.
Dry-running operation causes increased wear and is to be
avoided. Therefore, in manual operation the pump must be
immediately unplugged when water fails to flow.
Avoid running of the pump for more than 10 min. against closed
delivery side of the pump.
Sand and other abrasive substances cause increased wear and
reduce the pump’s output.
Take care that the pump is located where the inlet openings at
the suction base are obstructed neither completely nor partly.
Stand the pump on a brick if using in a pond.
The pump is automatically switched off on overheating by
the built-in thermal motor protector. After having cooled down,
the motor automatically switches on again (see 6. Trouble
Shooting).
The automatic deaerating valve eliminates any air pockets in
the pump. During this process, air escapes through the vent
bores

and air bubbles appear underwater. This is not a defect
of your pump, but serves to deaerate the pump.
It may take several seconds for the air to escape when the
pump is immersed for the first time.
