- Position the Pump: Place the pump in your aquarium sump or desired location. Ensure it is fully submerged if used internally, or securely connected to external plumbing if used in-line.
- Connect to Controller: Connect the pump's cable to the designated port on the controller. Ensure the connection is firm and secure.
- Connect Power Adapter: Connect the power adapter to the controller, then plug the power adapter into a grounded electrical outlet.
- Initial Start-up: Once all connections are secure and the pump is submerged (if applicable), power on the unit. The pump should start operating.

7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pump.
- Disconnect Power: Always unplug the pump from the power outlet before performing any maintenance.
- Rotor and Impeller Cleaning: Periodically remove the pump's front cover and impeller assembly. Clean any debris, algae, or calcium buildup from the impeller and its chamber using a soft brush and warm water. For stubborn deposits, a mild vinegar solution can be used, followed by thorough rinsing.
- Shaft Inspection: Inspect the ceramic shaft for wear or damage. Replace if necessary.
- O-Ring Inspection: Check all O-rings for cracks, tears, or compression. Replace worn O-rings to maintain a watertight seal. Applying a small amount of silicone grease to O-rings can help with sealing and longevity.
- External Cleaning: Wipe down the exterior of the pump and controller with a damp cloth. Ensure no water enters the controller or power adapter.
- Reassembly: Reassemble all components carefully, ensuring all parts are correctly seated and secured.
