Maintenance
Unplug the pump before maintenance. Blue Eco series are basically treated as low maintenance. In normal case maintenance is restric-
ted to impeller checking for clogging. Remove potential objects from the impeller with a thin, spiky tool. A reduced delivery rate of the
pump is generally caused by waste in the impeller. In the case of calcification (especially when used in salt water) remove the scale with
a weak acid like vinegar. Avoid sidewise pressure to the impeller or the rotor. The pump can be completely disassembled for cleaning.
The rear bearing can be easily removed by unscrewing of the bearing plate counter clockwise. Use an appropriate tool to move the
shaft to the front, so the impeller unit can be removed much easier. In fresh water applications, calcification generally occurs before and
after a complete pond filling. The dissolved lime scale will precipitate within 2 or 3 days.

Use a M6-Allan key to remove the titanium screws (1), which mount the pump head to the motor housing. Now, the complete pump
head can be removed. If necessary, remove the complete impeller from the 240/320 unit by pulling out the shaft after removing the
O-ring. For the models 500/900/1500/2200 you need to remove the nut on the impellers front. This will reveal 3 screws that also need
to be removed. You can now remove the shaft. 13
Be very careful, because the impeller is fixed to its position by a strong magnet. Releasing the shaft occasionally may hit the bearing
