General operating description

The EHEIM professionel 3 external filter cleans the aquarium water in a closed loop. The professionel 3 external filter has two suction channels for individual placement of suction areas in the aquarium. The built-in maintenance-free pump ensures continuous circulation. Water from the aquarium is passed through several filter layers where it is filtered mechanically, biologically or by adsorption before flowing back into the aquarium. For the filter to function, air has first to be removed from the system. This is easily done using the built-in priming aid.

Note: For optimal filter performance and trouble-free operation, it is essential to use EHEIM original filter materials (see chapter on Filling of Filter Materials).

Unpacking

When unpacking, check that all parts are present. Some installation accessories are packed in the filter container.

- Tilt out all four closing clips on the filter head, push up and fold out. Remove pump head (see Point 7). Remove prefilter, lattice screen cover and filter pad (white) from the container (see Point 8). Pull out filter inserts by the handle (see Point 9).

Installing the hose

1 Place a strainer on each suction pipe and fit at the desired locations in the aquarium with the help of the suction holders.

2 Outlet bend and nozzle tube are connected with a short section of hose and likewise fastened to the inside wall of the tank with suction pads. The plug for the open end of the nozzle tube is not fitted until the filter is running.

Tip: The nozzle tube can be installed either below or at water level, depending on the degree of surface movement desired. Cut each hose to the required length and push up at least 1 cm on to the suction pipe and outlet bend. Make sure that the hoses are laid as short as possible and that they do not sag or kink. Sagging hoses can worsen the suction process considerably.

Tip: Any kinks that form can be pressed out if the hoses are rendered supple in hot water.

3 Connect the suction pipe hoses to the left and right hose connectors on the adapter (marked ▼) and join the outlet bend to the adapter with the middle hose connector (marked ▲ Push up all three hose ends until they lock into place (if necessary, render supple with hot water beforehand).

4 Then, lay the two-part hose guard right round the assembled ends close to the adapter, hook in laterally and clip together.

Note: Be sure to use original EHEIM hoses. Check all hose connections at regular intervals to make sure they fit properly.

Installing the filter

5 When choosing a location for the filter, pay attention to the prescribed vertical clearance. To achieve optimal operational safety, the distance between the water surface and the filter bottom may not exceed 180 cm. However, the upper edge of the pump head should be at least 10 cm below the surface of the water. It is better to place it underneath the aquarium.

Tip: The EHEIM professionel 3 external filter has 4 castors. By tilting slightly, the filter can easily be placed in the cabinet. In the standing position, the load is removed from the castors.

Note: Since a wide variety of varnishes and polishes are used when processing timber, the feet of the appliance can leave visible traces on furniture or parquet floors as a result of chemical reactions. Therefore the device should not be placed on unprotected wooden surfaces.

tion: Always operate the filter in a standing position.

Filling with filter materials

Remove adapter

6 Turn shut-off lever on the adapter to the OFF position. Press the red safety catch (can only be pressed when the shut-off lever is in the OFF position). The safety adapter springs out of its holder and can be removed.

Open filter

7 Tip out all four closing clips on the filter container, push up and fold out. Remove pump head.

8 Take prefilter, covering grid plate and filter pad (white) out of the container.

9 Pull out filter inserts by the handle. The recessed handle can be pulled up and out.

Filling

To ensure optimal, trouble-free functioning of your EHEIM professionel 3 external filter, we recommend that you use original EHEIM filter materials. Only they are designed precisely for use with the EHEIM external filter, provide an ideal surface for purifying bacteria to colonise and ensure clean, healthy aquarium water. You can buy the right media set for the EHEIM professionel 3 from your pet shop dealer, order number 2520800.

10 Fill the bottom filter insert with EHFIMECH to just below the edge. Fill the second and third filter insert to just below the edge with SUBSTRAT pro.

Attention: Do not overfill as otherwise the filter inserts will not fit on top of each other

11 Next, rinse the filter medium in the filter insert under running water, mixing thoroughly at the same time, until no cloudiness is visible in the water.

12 Insert the filter insert filled with EHFIMECH at the bottom of the filter container and press down firmly onto the base runners.

13 Insert the second and third filter inserts (both filled with SUBSTRAT pro) after rinsing in the same way. Push the handles back in and make sure that all filter inserts lie flush on top of each other.

14 Next, lay the white filter pad on the top filter insert so that it is placed on the pushed-in handle.

Attention: The white filter pad must not be under the handle!

- Place the lattice screen cover on the white filter pad.

Prefilter

Function: The prefilter collects coarse dirt from the aquarium water so that the water that flows through the filter inserts has been pre-filtered. This substantially reduces the amount of dirt that reaches the filter inserts and guarantees highly efficient biological decomposition of pollutants and a long service life. The prefilter can easily be removed. To make interim cleaning even easier, the scope of delivery includes a dish for transporting the prefilter.

15 Insert prefilter with blue filter pad in the filter container so that that the overflow area is above the partition.

Note: The priming system only functions when the prefilter is empty.

Close filter, insert safety adapter

16 Check that the gasket fits properly on the pump head and the sealing ring fits properly on the prefilter and remove any soiling. Check for soiling on the sealing surface on the upper edge of the container, clean if necessary and grease lightly with EHEIM Care Spray, Order No. 400 100 0.

- Place pump head on filter container and close all four clips.

17 Push safety adapter into the pump head, applying light pressure, until it engages with anaudible CLICK. The shut-off lever must be in the OFF position to insert the adapter as otherwise a safety mechanism prevents it from engaging.

Taking into operation

18 First turn the shut-off lever on the safety adapter to the ON position to open the three valves. If the shut-off lever cannot be turned to the ON position, the safety adapter has not been fitted correctly to the pump head. In that case, repeat step 17.
19 Press the suction aid firmly several times until the filter container automatically fills with water. As soon as the container is full the mains plug can be plugged in to begin operating the filter. Make sure that the nozzle tube (delivery side) is above the surface of the water during the filling process so that the device is optimally bled of air.

Attention: Depending on the way the hoses are laid, initially only one of the two hoses with water. In that case, you can squeeze the filled suction channel firmly to get in your fingers until the empty hose has filled.

- Then place the plug in the open end of the nozzle tube.

Regulating the flow

20 To set the desired filtering performance on the delivery side, turn the shut-off lever on the safety adapter slowly in the OFF direction. The float in the indicator window shows the actual flow of water.

Indicator

21 The indicator provides continuous information about the volume of water flowing through and signals any faults that may occur. If the float touches the red bar, the filter is not performing to its full capacity and the filter system must be checked (see what to do if..., pages 17-19).

Service and maintenance

• First turn the shut-off lever on the safety adapter to the OFF position (see step 20). Pull out plug from mains. Remove safety adapter (see step 6).
• Tilt the filter slightly forward, using the recessed grips and pull out of the cabinet on the castors. Open all four closing clips and remove the pump head.

Interim cleaning (prefilter)

22 Pull prefilter out of the container by the two handles and place in the prefilter transportation dish. Empty prefilter and rinse out blue filter pad thoroughly under lukewarm running water until the water runs clear.

Tip: Renew blue filter pad after the second or third cleaning (Order No. 2616802).

• Remove lattice screen from the container and check to see if the white filter pad is very dirty. Replace if necessary. The white filter pad is for mechanical fine filtering. Since the dir particles that cling to it cannot be completely washed out, the filter pad may only be used once. Use a new filter pad (Order No. 2616802).
• Replace prefilter in the filter container. Check seals on the pump head and the upper edge of the container and clean off any soiling. Replace pump head. Close all four closure clips. Reinsert safety adapter (see step 17).
• Turn shut-off lever to the ON position (see step 18) and press suction aid several times (see step 19). Then take the device into operation by plugging it into the mains.

Thorough cleaning

- Remove prefilter, lattice screen, filter pad and all three filter inserts from the filter container. Rinse filter media in the filter inserts thoroughly under lukewarm running water until water runs clear. The white filter pad is for mechanical fine filtering. Since the dirt particles that cling to it can not be completely washed out, the filter pad may only be used once. Use a new filter pad (Order No. 2616802).

The blue filter pad (Order No. 2616802) can be used two or three times more. Wash out gently under running water before reinsertion so that some of the bacteria that have colonised it remain.

Tip: When changing the SUBSTRAT pro, mix approx. one third of the used filter medium with the new material so that the bacteria cultures multiply more rapidly.

- Wash out the filter container then push the filter inserts back in. Press the bottom one on to the base runners and make sure the other filter inserts fit tightly. Then lay a new filter pad on the top filter insert. To do this, the handle must be pushed in. Lay the lattice screen on top and insert the prefilter.

Attention: The white filter pad must not be laid beneath the handle of the filter insert.

- Check the upper edge of the filter and the gasket in the upper part of the filter for soiling and damage. If need be, replace the gasket. Spray upper edge of container lightly with EHEIM Care Spray (Order No. 4001000), replace upper part of filter and close all four clips. Place filter in cabinet.

- Reinsert safety adapter (see step 17).

Note: Check all hose connections at regular intervals to make sure they fit properly.

- For the container to fill with water, water circulation is reinstated by pressing the primer several times. Then plug into the mains to begin operation.

Note: The priming system only works when the prefilter is empty.

Cleaning the hoses

Clean hoses regularly with an EHEIM universal cleaning brush (Order No. 4005570).

Cleaning the pump chamber

23 Open pump cover by turning the sealing ring and remove.

Note: With these devices, magnetic fields can cause electronic or mechanical disturbance or damage. This can also affect cardiac pacemakers. The safe distances required can be found in the manuals for these medical appliances.

tion: Due to strong magnetic forces, there is a risk of crushing the fingers when g out servicing work. It is best to pull the impeller out with pliers.

24 Pull impeller out of the pump chamber.

25 Carefully rinse off ceramic shaft (risk of breakage) and clean all parts, including the pump chamber, lubrication channel and pump cover with a soft brush (cleaning set Order No. 4009560).

- Replace all parts and close pump chamber by turning the sealing ring.

Cleaning the indicator

- Remove safety adapter (see step 6). Empty all hosepipes. Then, and only then, open hose guard and remove hoses from safety adapter.

26 Press together safety catch on the back of the safety adapter and move indicator lid for ward to remove.
27 Position the indicator lid further up and use it to lever the indicator housing out of the safety adapter.
28 Remove indicator housing.
29 Remove brace carefully and take the float and spring out of the indicator housing.

Make sure you do not damage the spring. Clean the indicator housing with cleaning brush Order No. 4009560. Replace float with spring and fasten by means of the brace. Reinsert the indicator housing into the safety adapter and press the indicator lid in until the catch engages.

Gaskets and sealing rings

Spray all gaskets and sealing rings with EHEIM Care Spray Order No. 4001000 each time you clean. This keeps them supple for longer and increases their service life. Be sure to replace any damaged seals (see list of spares).
