Installation Instructions
Note: Please verify that all components of the pump are undamaged before putting it into function. To prevent noise and disturbance caused by vibrations, position the pump so it avoids lateral contact with the aquarium glass. Avoid placing the Koralia Nano in an upward position on the bottom.

  • Unwind the electric cable.
  • Insert the cylinder on the sphere attachment to the pump in the proper slot.
  • Immerse the pump completely and turn it in a vertical position in order to allow any air to come out of the impeller chamber.
  • Attach the pump with the internal part of the suction cup and magnet support to the aquarium side. Be sure to clean the surface before attaching the support.
  • Adjust flow direction as desired.
  • Connect to electrical supply.

Note: Before any kind of intervention, always disconnect electrical supply of the pump and any other appliance placed in the water.

  • Regular cleaning and maintenance will guarantee the pump better and longer performance.
  • With one hand, hold the pump assembly. Use your other hand to remove the external magnet.
  • Disassemble the unit.
  • Clean the impeller assembly, the chamber and the bearings removing deposits with a soft brush. Do not use detergents or solvents.
  • If necessary, clean the grid of the lower and upper chamber by putting it under running tap water or using a soft brush to remove algae and other residue.
  • Reassemble everything in reverse order. Make sure the notches on the pump chamber correspond and that the shaft is placed correctly.
  • In case of abnormal noise and reduced performance caused by sudden changes in electricity supply, restart the pump.
