Connecting an external aerator pump
► Connect the aerator rod in the container to an external aerator pump. OASE recommends:
Volume Hel-X biomedia
60 l
80/85 l
How to proceed:
O
1. Connect the hose from the external aerator pump to the air connection and fit the air connection onto
the container.
– For thinner ∅ 4 mm air hoses, use the 4/9 mm adapter and secure the connection with a cable
binder if necessary.
During the run-up phase, only use an air volume of approx. 1000 l/h to circulate the Hel-X biomedia.
Excessive turbulence delays the initial colonisation of micro-organisms.
If the movement of the Hel-X biomedia in the bio chamber keeps stopping, move the bubbler stone
slightly to optimise circulation.

Commissioning/start-up
► Thoroughly clean the pond before starting up the filter system for the first time to ensure that the filter
system is not overloaded by excessively soiled water. OASE recommends using the PondoVac pond
vacuum cleaner for cleaning the pond.
– This cleaning measure is normally not necessary for newly installed ponds.
► It is necessary to operate the filter system for 24 hours a day during the pond season.
W A R N I N G
Possible death or severe injury from hazardous electrical voltage!
► Prior to reaching into the water, isolate (switch off and disconnect) all units/devices used in the water.
► Isolate the device (disconnect from the power supply) before carrying out any work on it.
N O T E
A dimmer or timer will destroy the device.
► Only connect the device to a power supply without dimmer.
► Do not use a timer.
N O T E
Never allow the rinsing pump to run dry. Possible consequences: The rinsing pump will be destroyed.
► Check the water level at regular intervals. Ensure that the rinsing pump is always under water during
operation.
► Do not switch on the control system until the container is flooded with water.
