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.

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.
