Important Setup & Maintenance Guidelines

To maximize the lifespan of your Marine Blue filter and ensure optimal performance, please strictly follow the manufacturer's safety instructions:

• Crucial Priming Step: Do not operate without water! Before plugging the device into an electrical socket, you must manually fill the filter casing with aquarium water. If the water is below the minimum level, the pump cannot draw water, which will severely affect the lifetime of the motor.

• Routine Cleaning: If you notice a significant drop in water output, shut down the filter immediately and clean or replace the internal filter sponge.

• Electrical Safety: Only perform maintenance and clean the filter when the power is completely switched off and unplugged. Always keep your hands dry when operating the machine or handling the power cord.

• Voltage Requirements: Ensure your local power supply matches the rated voltage. The filter cannot function properly in low-voltage situations.
