8. TROUBLESHOOTING GUIDE
NOTE:
Prior to undertaking any actions described here, the filter (the pump and the UV sterilizer) should be discon-
nected from the power supply by pulling out the plugs.
8.1. Filter cover cannot be closed
Cause
Solution
The main gasket (5) is improperly installed.
Place the gasket properly in the cover groove.
Bad placement of filtration media.
Place the magazines with filtration media so that they fit
each other and the filter container perfectly.
Overfilled media magazines.
Remove the excess media. Do not put too much filtration
media in the magazines – see fig. 8.
8.2. The motor does not work
Cause
Solution
Broken impeller axis.
Address manufacturer’s service.
Damaged electric cord.
Replace entire cover (4) – it is not allowed to repair or re-
place the electric cord.
Blocked or damaged impeller.
Perform pump maintenance according to subsection 7.3
or replace the impeller.
8.3. Too much air in the filter (splashing sound), or after starting the pump the filter does not
deaerate automatically
Cause
Solution
Lack of tightness of the intake system elements, in untight
spots the air is sucked in permanently.
Improve the tightness of the intake system elements.
During the maintenance, the gasket (15) was forgotten
– see figure 21.
The gasket should be installed.
The internal deaerating canal is blocked in the cover and/
or in the impeller chamber cover (16).
The canal should be made permeable according to the
descriptions at figures 21 and 22.
8.4. Filter output deteriorates significantly
Cause
Solution
Improperly composed filtration media.
Check whether the composition of the filtration media is
compliant with the one recommended by
AQUAEL.
Impure filtration media.
Clean or replace the media according to subsection 7.2.
Too many additional accessories connected to the intake
system or to the outlet.
Check and possibly remove the elements that are not
indispens able.
The water circulation during filtration is not functioning
properly.
Verify whether the filter is not placed too low in relation to
the water level or whether there is no undesirable obstacle
in the water circuit, e.g. folded elastic conduits.
Contaminated pump.
Perform the maintenance according to subsection 7.3
Contaminated intake/outlet elements.
Disconnect this system and clean all of the elements.
8.5. Filter cannot be filled with water as per subsection 6.1
Cause
Solution
The filter is placed too high thus the filter intake is above
the aquarium water level.
The top surface of the filter should be located at least 10
cm below
the aquarium water level.
The user has performed few piston movements when
pumping the air out of the filter container (see fig. 16).
Carefully read the description at figure 16 and act accord-
ingly.
The intake and/or outlet system (temporary) are not
properly submerged or are untight and draw the air into
the filter.
Place these elements according to description at figure
15 deep in the water, check the tightness of their con-
nections .
