Setup and Installation
Follow these steps to properly install the Eheim AEH7428718 Adapter onto your Eheim canister filter.
- Prepare the Filter: Ensure your Eheim 2076/2078 canister filter is disconnected from power and all hoses are drained. If replacing an old adapter, carefully remove it from the filter head.
- Inspect the Adapter: Before installation, inspect the new adapter for any signs of damage or manufacturing defects. Ensure the O-rings on the bottom connections are properly seated.
- Attach to Filter Head: Align the two bottom connectors of the adapter with the corresponding ports on the Eheim filter head. Gently push the adapter down until it clicks securely into place. You should hear and feel a positive lock.
- Connect Hoses: Attach the aquarium hoses to the two hose connections on the top of the adapter. The adapter typically has arrows indicating flow direction (inlet and outlet). Ensure hoses are pushed firmly onto the barbed fittings and secured with hose clamps if necessary to prevent leaks.

Operating Instructions
The Eheim AEH7428718 Adapter features a flow control lever that allows you to regulate or shut off water flow to and from the filter.
- Opening Flow: To allow water flow, push the gray lever fully down. This opens both inlet and outlet valves, enabling water to circulate through the filter.
- Closing Flow: To stop water flow, pull the gray lever fully up. This closes both inlet and outlet valves, isolating the filter from the aquarium. This is useful for maintenance or when removing the filter for cleaning.
- Partial Flow Control: The lever can be positioned between fully open and fully closed to adjust the flow rate, if desired. However, for optimal filtration, it is generally recommended to operate the filter with full flow.

Maintenance
Regular maintenance of the adapter ensures its longevity and proper function.
- Cleaning: Periodically, when performing filter maintenance, remove the adapter and rinse it thoroughly under clean water to remove any accumulated debris or algae.
- O-Ring Inspection: Inspect the rubber O-rings on the bottom connectors for signs of wear, cracking, or flattening. Damaged O-rings can lead to leaks and should be replaced immediately.
- Lubrication: A thin layer of silicone grease (aquarium-safe) can be applied to the O-rings to maintain their flexibility and ensure a smooth, watertight seal.
- Lever Operation: If the flow control lever becomes stiff, ensure no debris is obstructing its movement. Do not force the lever.
