3. Setup and Installation of Spare Parts

Before attempting any installation or replacement, ensure your EHEIM Professionel 2 filter is disconnected from the power supply and all water lines are properly shut off and drained. Refer to your main EHEIM filter manual for specific disassembly and reassembly instructions for your model (2026, 2028, 2126, or 2128).

1. Identify the Part: Use the exploded diagrams (Figure 1 and Figure 2) and the part descriptions in Section 2 to correctly identify the spare part you need to replace. Match the order number to ensure you have the correct component.
2. Disassembly: Carefully disassemble the relevant section of your EHEIM filter according to the instructions in your main filter manual. Pay close attention to the orientation and placement of all components, especially seals and gaskets.
3. Replacement: Remove the old, worn, or damaged part. Install the new genuine EHEIM spare part, ensuring it fits securely and correctly. For components like sealing rings, ensure they are properly seated and free from twists or pinches to prevent leaks.
4. Reassembly: Reassemble the filter in reverse order of disassembly. Double-check all connections, especially hose clamps and adapters, to ensure they are tight and leak-proof.
5. Testing: After reassembly, slowly reintroduce water to the filter system and check for any leaks before reconnecting the power supply. Monitor the filter's operation for the first few hours to ensure everything is functioning correctly.

Caution: Always disconnect power before performing any maintenance or part replacement. Failure to do so may result in electric shock or damage to the equipment.

4. Operating the Filter (After Part Replacement)

Once all spare parts have been correctly installed and the filter system reassembled and checked for leaks, you can resume normal operation. Refer to your original EHEIM Professionel 2 filter manual for detailed operating instructions, including priming and starting the filter.

Ensure that water flow is consistent and that the filter operates quietly, indicating proper assembly and function of the new components.

5. Maintenance of Spare Parts

While these are spare parts, their proper function contributes to the overall maintenance of your filter. Regular inspection and timely replacement are key.

• Sealing Rings: Inspect sealing rings (e.g., for double tap units, pump head) regularly for signs of wear, cracking, or hardening. Replace them immediately if any damage is observed to prevent leaks.
• Hose Clamps and Connectors: Check hose clamps and connectors for tightness and integrity. Ensure hoses are securely attached and not kinked.
• Impellers and Shafts: If replacing impeller components, ensure they are kept clean and free of debris to maintain efficient water flow and prevent premature wear.
• Filter Media Baskets: Clean filter media baskets during routine filter maintenance to ensure proper water circulation and prevent clogging.

Always use clean water and appropriate tools when performing maintenance to avoid damaging delicate components.

6. Troubleshooting (Related to Spare Parts)

If you encounter issues after replacing a spare part, consider the following common troubleshooting steps:

• Leaks:
  • Check all sealing rings and gaskets for proper seating and damage.
  • Ensure all hose connections and adapters are securely tightened.
  • Verify that the filter head is correctly seated and locked onto the canister.
• Reduced Flow/No Flow:
  • Ensure the impeller is correctly installed and free from obstructions.
  • Check that all inlet and outlet connectors are clear and not clogged.
