priming so that any air in the intake line can escape.
Depending on the suction height and the amount of air in the intake line, priming can take
anywhere between 30 seconds and 5 minutes. If it takes longer than this, the pump should be
refilled with water. If the pump is removed again after use, it must always be refilled with water
whenever it is connected up and used again.
Maintenance instructions
The pump is basically maintenance free. To ensure a long service life, however, we recommend
regular checks and care.
Warning!
Before every servicing, switch off the pump and remove the plug from the socket.
If the pump is not going to be used for a long time or has to be removed for the winter months,
rinse it out with water, empty it completely by unscrewing both vent plugs and allow it to dry.
If there is a risk of frost, the pump must be emptied complete.
After long stoppages, make sure the rotor turns correctly by briefly switching the pump on and
off. If the pump becomes blocked, connect the pressure line to the water line and remove the
intake hose. Open the water line, Switch on the pump several times for approx 2 seconds, Most
blockages can be removed in this way.
Regularly maintain your pump and keep the air pressure in tank at 1.5bar.
