Fastening the unit to the bottom of the pond

 H
• Shorten two wire cables to the desired length (minimum 16.5 ft).
• Form loops at each of the cable ends and fasten these with cable clamps.
• For anchoring to the bottom of the pond, screw the two threaded hooks into, for instance,
two sufficiently heavy stones using dowels.
• Attach the cables to the threaded hooks using the safety hooks and lower the stones to the
bottom of the pond.
– Adhere to the specified anchoring angles so that the aerator cannot move.
• Anchor the aerator using the two wire cables and the safety hook.
• Relieve strain from the power cable and protect the power plug from wetness.

Commissioning/start-up

NOTE
The unit will be destroyed if it is operated with a dimmer. It contains sensitive electrical compo-
nents.
Do not connect the unit to a dimmable power supply.

NOTE
Never allow the pump to run dry. Otherwise the pump will be destroyed.
 Only operate pump while it is submerged.

Switching ON/OFF

• Switching on: Plug the power plug into the outlet.
– The unit switches on immediately.
• Switching off: Pull the power plug from the outlet.

Environmental Function Control (EFC)

When started up, the pump automatically performs a pre-programmed self-test (Environmental
Function Control (EFC)). The pump detects if it is running dry / blocked or submerged. The pump
switches off automatically after approx. 90 seconds if it runs dry/is blocked. In the event of a
malfunction, disconnect the power supply and "flood the pump" or remove the obstacle. After-
wards, the unit can be restarted.
