3. Installation of Spare Parts
This section outlines the general procedure for replacing spare parts. Always refer to your original EHEIM filter manual for model-specific disassembly and reassembly instructions.
- Preparation: Disconnect the filter from power and turn off water flow. Disconnect hoses and carefully remove the filter from its location.
- Disassembly: Open the filter head and remove filter media baskets. Depending on the part to be replaced, further disassembly of the filter head or canister may be required. Refer to the exploded diagrams (Section 2.1) for guidance.
- Part Replacement: Carefully remove the worn or damaged part. Install the new genuine EHEIM spare part, ensuring it fits correctly and securely. Pay close attention to the orientation of parts like impellers and the proper seating of sealing rings.
- Reassembly: Reassemble the filter in reverse order of disassembly. Ensure all connections are tight and all sealing rings are properly seated and lubricated (if applicable) to prevent leaks.
- Testing: Reconnect hoses and restore water flow. Prime the filter according to your filter's original instructions. Plug in the power and check for proper operation and any leaks.
4. Ensuring Proper Operation After Part Replacement
After replacing any spare part, it is crucial to verify the filter's proper function to maintain a healthy aquarium environment.
- Leak Check: Immediately after reassembly and startup, carefully inspect all connections and seams for any signs of water leakage. A new sealing ring (Order no. 7428770) should provide a tight seal.
- Flow Rate: Observe the water flow from the outlet pipe. It should be consistent and strong. A reduced flow might indicate an issue with the impeller (e.g., Order no. 7603330) or a blockage.
- Noise Level: The filter should operate quietly. Unusual noises, such as grinding or rattling, could suggest an improperly installed impeller or debris in the pump housing.
- Priming: Ensure the filter is fully primed and free of air pockets. Air in the system can reduce efficiency and cause noise.
5. Maintenance and Part Replacement Schedule
Regular inspection and timely replacement of worn parts are essential for the longevity and efficiency of your EHEIM professionel 3 filter.
- Sealing Rings (Order no. 7428770, 7428680): Inspect every 6-12 months for cracks, hardening, or deformation. Replace immediately if any damage is observed to prevent leaks.
- Impeller (Order no. 7603330, 7603340, 7603350, 7603420): Check annually for wear on the magnet or blades, and for any debris accumulation. Replace if damaged or if filter performance significantly drops.
- Inlet Strainer (Order no. 7471800): Clean regularly (e.g., monthly) to prevent blockages. Replace if physically damaged or brittle.
- Hose Clamps (Order no. 7212258): Inspect during filter maintenance for tightness and signs of corrosion or damage. Replace if they no longer provide a secure grip.
- Rubber Feet (Order no. 7312698): Check periodically for deterioration. Replace if they become hard, cracked, or fall off, as they help reduce vibration and stabilize the filter.
6. Troubleshooting Common Issues with Spare Parts
If you encounter problems with your filter, replacing specific spare parts can often resolve the issue.
- Reduced Water Flow:
- Cause: Clogged inlet strainer, worn impeller, or debris in pump.
- Solution: Clean or replace Inlet Strainer (Order no. 7471800). Inspect and replace Impeller (Order no. 7603330, 7603340, 7603350, 7603420) if damaged.
- Water Leaks:
- Cause: Damaged or improperly seated sealing rings, loose hose connections.
- Solution: Replace Set Sealing Ring for Canister (Order no. 7428770) or Set of sealing rings for safety adapter (Order no. 7428680). Ensure Hose Clamp Complete (Order no. 7212258) is securely fastened.
- Excessive Noise/Vibration:
- Cause: Worn impeller, air in the system, or unstable filter placement.
- Solution: Inspect and replace Impeller (Order no. 7603330, 7603340, 7603350, 7603420). Ensure filter is properly primed. Replace Rubber Feet (Order no. 7312698) if worn.
