Setup
- Placement: Position the VarioS 8 pump in your sump or desired location, ensuring it is fully submerged and stable.
- Plumbing Connection: Connect your aquarium plumbing to the pump's inlet and outlet. The pump is designed to handle a flow rate of up to 2700 gallons per hour (GPH).
- Controller Connection: Connect the detachable controller to the pump using the waterproof union. Ensure the connection is secure to prevent water ingress.
- Safety Float Switch Installation: Install the safety float switch in your sump at a level that will detect low water conditions. Connect the float switch to the designated port on the controller. This feature will automatically shut off the pump if water levels drop too low, preventing dry running.
- Power Connection: Connect the power supply to the controller, and then plug the power supply into a grounded electrical outlet.
- Initial Priming: Before starting, ensure the pump chamber is filled with water to prevent airlock.
Operating Instructions
The VarioS 8 pump offers variable speed control for optimal performance.
- Power On/Off: Press the power button on the controller to turn the pump on or off.
- Flow Adjustment: Use the dial or buttons on the controller to adjust the flow rate. The pump can be set to various speeds to match your system's requirements.
- Feed Mode: The controller may feature a "Feed" button or mode. Activating this will temporarily pause the pump for a set duration (e.g., 10 minutes) to allow for feeding without water circulation. Press the button again to resume normal operation.
- Safety Features: The integrated safety float switch will automatically shut down the pump if the water level drops below a safe operating threshold, protecting the pump from dry running damage.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your VarioS 8 pump.
- Cleaning the Impeller: Periodically remove the pump head and clean the impeller and ceramic shaft. Calcium buildup and debris can reduce efficiency and cause noise. Use a soft brush and vinegar or a mild acid solution for stubborn deposits.
- Housing Cleaning: Clean the pump housing and intake screen to ensure unrestricted water flow.
- Controller Care: Keep the controller clean and dry. Avoid exposing it to water or high humidity.
- Cable Inspection: Regularly inspect the power cable and connections for any signs of wear or damage.
