Introduction

Thank you for purchasing this quality product. To minimize the risk of injury we urge that our clients take some basic safety precautions when using this device. Please read the operation instructions carefully and make sure you have understood its content. Keep these operation instructions safe.
Safety instructions

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 authorized 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 in the water, DO NOT reach for it! Cut the power supply 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 an abnormal state. The supply cord of the appliance cannot be replaced. If the cord is damaged, the appliance 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.
Always 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 that 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.

Installation

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.”
You can then access your filter trays to clean the filter media or add filter media. Repeat step one to refasten the filter head to the filter base.* UV unit depends on the model.
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. After this, attach a hose to each tap and secure using the screw taps.
According to the diagram, then attach the input downpipes and output spray bars according to the diagram.
Then press down the primer button 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.
The switch (3) to turn on and off the UV and indicator is on the filter side. Please check the UV regularly when cleaning your filter to make sure it works best.
Under any condition, when the filter base is separated from the filter head, the protect switch will turn off the device. Then the UV will be extinguished to avoid any filter base damage.

Replacing the UV light tube

Filter operation and troubleshooting

Noise reduction/external air
Especially the suction intake and the connected suction surface must 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 deaeration process (evacuate the air) by activating the manual pump. Please make sure that the potential flow is adjusted to the inlet-outlet connector. As 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 cannot 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 clamping points that connect the cover lid with the filter basis.
The remedy is here as simple as the failure itself. You must rinse and check the O-rings. Make sure that the spots where the O-rings must 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 regular cleaning is carried out. This problem can also appear in the case of a new installation because of sand, for instance.
Please allocate sufficient time for rinsing and cleaning; if this is not done carefully and thoroughly, the aquarium canister filter may still leak after the O-ring sealings have been cleaned. If despite thorough 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 customer 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 filter cotton can quickly lead to a decrease in filter efficiency.
Aquarium 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. Above that, a layer of ceramic rings should follow. On the top level, we recommend a filter sponge covered with filter cotton. (This is an example; please adapt it to your practical aquarium.)
Additionally, and temporarily, you can place here another layer of activated carbon (in a net or partly available as a 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/semi-biological 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.
