For Optimal Performance: Always fully submerge the heater—never run it dry! – Set the power level based on season/ tank size (e.g., 300W for winter in a 50-gallon tank). – Position the heater near the water flow for even heat distribution; avoid direct contact with decorations or substrate, away from decor/ gravel to ensure even heat distribution. – Always fully submerge the heater before powering on to avoid damage and ensure accurate temperature sensing. – Mount the external digital controller securely in a dry, accessible spot for easy adjustments. Safety Monitoring: -Watch for alarms and error codes; the heater shuts off if the water level is too low or the temperature exceeds safe limits. 2. Troubleshooting: If the heater displays “HH” or “LL”, check the water temp and reset. – Buzzer alarm? Verify submersion or adjust temperature settings. 3. Maintenance: Wipe the glass surface monthly to prevent mineral buildup. – Replace every 2–3 years for peak efficiency.
