The heater features a memory function. In case of a power outage, the heater will remember your last temperature setting and automatically resume operation at that setting once power is restored. There is no need to reset the temperature.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your hygger Aquarium Heater.
- Cleaning: Periodically clean the heater unit to prevent algae and mineral buildup. Always unplug the heater and allow it to cool completely before removing it from the water for cleaning. Use a soft brush or cloth to gently wipe the surface. Do not use harsh chemicals or abrasive materials.
- Water Changes: When performing water changes, ensure the heater remains fully submerged. If the water level drops below the heater, it will automatically shut off. Unplug the heater before draining significant amounts of water.
- Cable Inspection: Regularly inspect the power cord and connections for any signs of damage, fraying, or corrosion. If any damage is found, discontinue use immediately and contact customer support.
