- Attach the PVC hoses to the inlet and outlet connectors on the filter head.
- Assemble the retractable water inlet pipe and secure it inside the aquarium using suction cups.
- Assemble the outlet pipe, choosing either the nozzle or spray bar, and secure it inside the aquarium.
- Ensure all connections are tight to prevent leaks.
3.3 Filter Placement and Activation
Proper placement is crucial for efficient siphoning and operation.
Image: Guidelines for activating the filter, showing that the water surface must be within 1.97 inches (5cm) from the tank rim and the canister filter at least 15.75 inches (40cm) below the water surface. It also warns against twisting hoses or tilting the filter.
- Place the canister filter on a flat, stable surface. The filter must be positioned below the aquarium's water level, with a minimum vertical distance of 15.75 inches (40cm) between the water surface and the filter unit for optimal siphoning.
- Ensure the water surface in the tank is no more than 1.97 inches (5cm) from the tank rim.
- Avoid twisting the water outlet hose or tilting/inverting the canister filter, as this can impede proper function.
3.4 Priming the Filter
The self-priming feature simplifies startup.
Image: Close-up of the filter's pull-vent valve, showing the action of lifting it to drain air and prime the pump.
- Once all connections are secure and the filter is positioned correctly, lift the pull-vent valve on the top of the filter head 2-5 times.
- This action will drain air from the system and automatically prime the pump.
- After priming, plug in the power cord. The filter should start operating.
4. Operating Instructions
4.1 Flow Control
Adjust the water flow to suit your aquarium's needs using the three independent control points.
