Introduction
Thank you for purchasing this quality product. To minimize the risk of injury we urge that our cli-
ents take some basic safety precautions when using this device. Please read the operation in-
structions carefully and make sure you have understood its content.
Keep these operation instructions safe.
Important safeguards
220–240>V C, 50>Hz, 15>W/20>W/50>W IP44
Please read thoroughly before installation and operation
To guard against injury, basic safety precautions should be followed when handling the appliance, in-
cluding:
The appliance has only been designed for aquarium and indoor use.
To avoid possible electric shock, special care should be taken since water is employed in the
use of this appliance. Do not attempt to repair it by yourself. Return the appliance to the au -
thorized service facility for maintenance or discard it.
Make sure that your outlet voltage corresponds to the stated voltage on the pump rating label.
If the appliance is submerged into the water, DO NOT reach for it! Please cut the power sup-
ply FIRST and then touch it.
Carefully examine the appliance after installation. It should not be plugged in if its electrical
components are wet.
Do not operate any appliance with a damaged cord or plug, or with a cord or plug in abnormal
state. The supply cord of the appliance cannot be replaced. If the cord is damaged, the appli -
ance should be scrapped.
Make sure that the electrical cord loops form a “Drip Loop” below the electrical outlet. The use
of a drip loop will help prevent any water leaks or splashes from running down the electrical
cord into your outlet. Instead of any water getting into your outlet, it will simply drip off the cord
at the lowest point in the loop.
Close supervision is necessary when the appliance is used by or near children.
lways unplug the appliance when not in use, before putting on or taking off parts, and before
cleaning.
Do not install or store the appliance where it is exposed to moisture or to temperatures below
freezing.
Make sure the appliance is securely installed before operating it.
Read and observe all the instructions supplied with the appliance and on the appliance.
The pump must not run dry.
Never use accessories which are not recommended by the appliance manufacturer. It may
result in fire, electric shock and/or personal injury.
Use the appliance ONLY for domestic purposes and in the way indicated in these instructions
and place it in a dry environment.

1. To set your filter up, the buckles (1) and (2)
should be unclipped from the main body of the
filter head; this will then separate the filter head
from the filter base.
2. You can then access your filter trays to
clean the filter media or add filter media. Re-
peat step one to refasten the filter head to the
filter base.
* UV unit depends on model.
3. Push the inlet and outlet taps into the filter
head and fasten using the small handle in
between the taps; this is also the valve shut.
fter this, attach a hose to each tap and se-
cure using the screw taps.

4. ccording to the diagram, then attach the in-
put downpipes and output spraybars.
5. ccording to the diagram, then press down
the primerbutton on top of the filter head; this
will prime the filter drawing water in through the
hose. Repeat, if necessary, until the entire
pipework is filled with water.
6. The switch (3) to turn on and off the UV and
indicator is located in the filter side.
Please check the UV regularly when cleaning
your filter to make sure it works best.
7. t any condition, when the filter base is separated form the filter head, the protect switch will turn off
the device. Then the UV will be extinguished to avoid any filter base damage.

shows.
2. When the quartz hose tube gap and the light
tubes connection gap are accordant, pull out
the quartz tube.
3. Pull out the old light tube.
4. Install the new light tube and the quartz
tube.

Filter operation and troubleshooting
Noise reduction/external air
Especially the suction intake and the connected suction surface has to be checked for tightness and to
be adjusted according to the aquarium water level. If this is not possible due to aquarium technical
reasons, seal the whole suction surface so that no external air can get into the filter.
Evacuating air from filter system
Take the return-flow hose that conducts the water from the filter to the tank and put it into a clean
bucket that is placed below the filter. Leave the hose inside the bucket and carry out the dearation pro-
cess (evacuate the air) by activating the manual pump. Please make sure that the potential flow is ad -
justed to the inlet-outlet connector. s soon as no air bubbles can be seen, seal the hose with a finger
and install it again on the return pipe at the top edge of the aquarium as intended.
Leakage after installation or cleaning
If a slight leakage still persists after the filter installation or the filter cleaning, the problem is most likely
the sealing between the hose connector adaptor and the filter head (cover lid).
The plug-in adaptor that the hoses are connected to has two O-rings on the lower side that seal the
connection inside the filter lid. If these O-rings are dirty, displaced (out of place) or damaged, they can-
not seal properly anymore and water escapes into the filter lid/aquarium filter cover.
The leak point is then the lowest point of the filter cover/lid and appears typically at the lateral clamp -
ing points that connect the cover lid with the filter basis.
The remedy is here as simple as the failure itself. You have to rinse and check the O-rings. Make sure
that the spots where the O-rings have to be inserted and positioned are free of dirt. On these particular
spots, algae formation can appear and impair or damage the O-rings sealing if no regularly cleaning is
carried out. This problem can also appear in case of a new installing because of sand, for instance.
Please allocate sufficient time for rinsing and cleaning; if this is not done carefully and thoroughly,
aquarium canister filter may still leak after the O-ring sealings have been cleaned. If, despite a thor-
ough cleaning, the water leakage at the spots above-mentioned still persists, you must check the O-
ring seating inside the adaptor. This requires opening the inlet/outlet adapter. Please contact our cus-
tomer service agents who are looking forward to helping you.

Basics – Filter media
The delivered filter media represents only the basic filter material needed for your aquarium.
Please inform yourself regarding what filter materials are suitable for your aquarium because these
can differ depending on the fish and plants living there.
Please use one filter cotton for only one filter stage. This should be regularly renewed because dirty fil-
ter cotton can quickly lead to a decrease in filter efficiency.
quarium external filters consist of several layers. The water sucked in is filtered in several stages.
The lowest layer consists of bio balls. These balls offer bacteria a large settling area and retain coarse
dirt. bove that, a layer of ceramic rings should follow. On the top level, we recommend a filter sponge
covered with a filter cotton. (This is an example; please adapt it to your pratical aquarium.)
dditionally and temporarily, you can place here another layer of activated carbon (in a net or partly
available as filter mat), and this will one of the filter layers. This should not be permanent, but only be
used after a medication treatment and for turbid water with suspended particles. (Not included.)
When you purchase a new aquarium filter or after it has been fully cleaned, the useful bacteria must
be enriched again. For this reason there are special bacteria cultures that can be supplied in the
aquarium to facilitate their settlement.
Basically, put the filters from bottom to top as follows:
1st stage: mechanical/semibiological filtering
2nd stage: biological filtering
3rd stage: chemical filtering (activated carbon, peat, phosphate, etc.)
If necessary, the aquarium filter can be extended to 4 stages by adding a mechanical or biological filter
stage.
