15 l/h per day in a mature and average charged
aquarium.
An early clogging could be caused by:
- Anomalous production of dirt in the aquarium.
Clean the aquarium more frequently and
remove the origins of dirt generation.
- The cleaning of the mechanical cartridge is not
efficacious. Clean the cartridge in the correct
way, by removing the lid at the bottom and
using the brush that comes with the unit. (for
a better result we suggest rinsing the
mechanical cartridge with warm water).
Q: Air bubbles continuously come out from filter
output.
A:
1. The filter evacuates the air entering through the
intake: remove or relocate the origin of air.
2. During normal operation, the filter may work with
a light negative pressure inside, and it could suck
air from the connection points. Check the
correct assembly and cleanliness of the intake
cross rim assembly and stem, AQUASTOP red
O-rings, filter canister gasket and cartridges’
O- rings.
3. Filter progressive clogging increases the negative
pressure inside the filter, which favours the
separation of the gasses dissolved in water.
These gases gather inside the filter, and are then
expelled through filter outlet. Clean the
mechanical pre-filter cartridge.
Q: After switching off and on of the filter, the filter
is On and the flow rate is zero or insufficient.
A: An air bubble could be trapped inside the impeller
chamber. By acting on the priming button, the
operation’s conditions previous to the power
being off are restored.

even the use of the priming button could not be
sufficient to solve the problem. In this case clean the
mechanical pre-filter cartridge.
Q: After having switched off the unit and cleaned
the mechanical pre-filter, the filter is On but
flow rate is zero or insufficient.
A: An air bubble could be trapped inside the
impeller chamber. By operating the priming
button, the normal operation of the unit can be
restored.
Q: After cleaning, max flow rate condition (fully
white flow graph) is not restored.

by:
1. Accidentally squeezed or collapsed hosing
2. AQUASTOP valve lever not fully lowered
3. Clogged hosing or cross rim assembly
4. Solids, debris or bacterial mud, block water
passage inside the filter or at pump outlet.
5. The valves of the priming system are dirty
or blocked
6. The chemical cartridge is still inside the
protective poly-bag
7. Filtration media block pump inlet
Q: When removing the filter head from the unit,
water comes out from the metal locking levers.
A: In order to avoid water spilling when cleaning,
during normal operation, the filter unit is not
completely full of water, but it maintains an air
chamber underneath the filter head to keep
water inside at such a level so that it does not
 overow.
During normal operations of cartridges opening or
AQUASTOP disengagement, water level inside tends
to rise.
Wrong operations may cause water to spill and to
gather inside the unit head.
The cartridge cups also serve the purpose by remov-
ing some water from the unit during maintenance
operation, and thus restoring the adequate water
level.
