USER MANUAL 250 EHEIM

– To guard against injury, basic safety precautions should be observed, including the following. READ AND FOLLOW ALL SAFETY INSTRUCTIONS. DANGER – To avoid possible electric shock, special care should be taken since water is employed in the use of aquarium equipment. For each of the following situations, do not attempt repairs by yourself; return the appliance to an authorized service facility for service or discard the appliance.

USA 1) If the appliance falls into the water, DON’T reach for it! First unplug it and then retrieve it. If electrical components of the appliance get wet, unplug the appliance immediately. (Non-immersible equipment only) 2 ) If the appliance shows any sign of abnormal water leakage, immediately unplug it from the power source. (Immersible equipment only) 3 ) Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended to be wet. 4 ) Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning or has been dropped or damaged in any manner. 5 ) To avoid the possibility of the appliance plug or receptacle getting wet, position aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug. A ”drip loop”, shown in the figure, should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The ”drip loop” is that part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water traveling along the cord and coming in contact with the receptacle. If the plug or socket does get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for presence of water in the receptacle. Close supervision is necessary when any appliance is used by or near children. To avoid injury, do not contact moving parts or hot parts such as heaters, reflectors, lamp bulbs, and the like. Always unplug an appliance from an outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect. Do not use an appliance for other than intended use. The use of attachments not recommended or sold by the appliance manufacturer may cause an unsafe condition. Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing. Make sure an appliance mounted on a tank is securely installed before operating it. Read and observe all the important notices on the appliance. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the appliance rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled. This appliance has a polarized plug (one blade is wider than the other). As a safety feature, this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Never use with an extension cord unless plug can be fully inserted. Do not attempt to defeat this safety feature. The EHEIM professionel 3 and professionel 3 e external filters offer – with their newly developed, integrated suction aid and the function-driven safety adapter – the optimum level of convenience and the highest level of safety. The large tank volume and the big prefilter in connection with the matched filter media stacking assure optimum water clarification and an efficient decomposition of pollutants.

7. What to do if . . .

. . . Top part of filter can’t be closed Cause Solution Filter inserts have been inserted wrongly. Push filter inserts and pre-filter in until they lie flush on top of each other. Filter inserts are too full. Do not overfill filter inserts. If need be, clean the touching surfaces. Gasket not fitted properly. Insert correctly into the groove provided in the upper part of the filter. Check for damage and if necessary replace. . . . Top of filter leaks Cause Solution Closing clips not closed properly. Close all clips properly. Sealing areas or gasket soiled. Clean seal areas and spray lightly with EHEIM silicone grease spray (Order no. 4001000). Sealing ring not fitted, inserted wrongly or damaged. Insert sealing ring correctly or renew. . . . Primer does not work Cause Solution

Cause Solution Prefilter flap in prefilter not closed. Check the prefilter flap for pollution and, if required, clean it. The prefilter flap must be unobstructed (see chapter 6.2, step 13). Prefilter is filled with water. Empty prefilter, repeat priming. Priming only works with empty prefilter. Check valve polluted / defective. Clean and, if required, replace the check valve (see chapter 6.3). . . . Pump does not work Cause Solution No mains supply. Plug in to mains. Shaft broken. Renew shaft (see list of spares). Impeller missing or blocked by bits of gravel, shells or similar. Fit impeller, clean pump chamber. . . . Filter performance has greatly deteriorated Cause Solution Safety adapter lever position not correct. Check lever setting and adjust. Safety adapter soiled. Remove safety adapter; open shut-off lever and clean openings with EHEIM cleaning brush (no. 4005570). Hose installation. Check that there are no kinks or marked narrowing of cross-section. Hose installation soiled. Clean hose installation with universal cleaning brush (no. 4005570). Strainer blocked. Remove coarse dirt, clean strainer. Filter media heavily soiled. Clean filter media. Filter media filled into a net bag. Never put long-term filter media in net bags or nylon stockings. This leads to a drastic reduction in pump performance within a short time. Filter media not cleaned properly. When cleaning, remove the filter media from the filter media basket and rinse through with lukewarm water. Filter media wrongly assembled. Check that filter media have been assembled correctly in the recommended layers of filtering. Fill bottom filter insert to just under edge with EHEIM MECH. Fill next filter inserts with EHEIM SUBSTRAT, also to just under edge. Never place white filter pad under the handle. Filter pad not renewed. Be sure to renew the filter pad each time you clean. Pump is dirty. Clean pump chamber, cooling and lubrication channel with EHEIM cleaning brush set (no. 4009560). Water is not circulating properly. Take filter into operation by priming (as described in the instructions). Make sure that the water runback (delivery side) is above the surface of the water during filling so that air is optionally bled from the device. Too many accessories installed on the hose system. Connected accessories reduce filter performance. Check and remove unnecessary accessories or operate via a separate water system. . . . Air in the filter Cause Solution

Filter location. The top edge of the pump head should be at least 10 cm beneath the surface of the water. It is better to place it underneath the aquarium. Air is being sucked in via the hose installation. Check that hose connector is fitted properly, and may be check whether hoses leak. Additional air supply (membrane pump). Do not install diffuser in the vicinity of the suction pipe. Filter media heavily soiled. Clean filter media. Filter media have been placed in net bags. Never put long-term filter media in net bags or nylon stockings. . . . The pump causes loud operating noise Cause Solution Ceramic sleeve not or incorrectly installed. Correctly install or, if required, replace the ceramic sleeve. (only in professionel 3 e - 350 Type 2074). Ceramic axis broken. Filtermassa’s in perlonzak of nylonkous. Keramische as gebroken.
