Usage Tips When used in conjunction with a wave-making pump, the hidden heater helps to balance the water temperature in the fish tank and also improves the accuracy of heating. – Always install the heater fully submerged in water before connecting to power to prevent damage and ensure safe operation. – Position Strategically: Place the heater near a water flow source (such as a filter outlet or wavemaker) to ensure even heat distribution throughout the tank. – Secure Mounting: Use the included suction cups or mounting brackets to fix the heater firmly to the tank wall. Ensure it’s not in contact with substrate, decorations, or tank walls to allow proper water circulation around the unit. – Controller Placement: Install the external controller in a dry, easily accessible area outside the tank to allow safe adjustments and clear visibility of the temperature display. – Routine Inspection: Check the heater and protective shell regularly for debris, algae buildup, or damage. Clean gently as needed to maintain optimal performance. – Use the Protective Shell: Keep the detachable shell in place to prevent fish from coming into direct contact with the heating element, especially in tanks with active or curious species. – Allow Cooling Before Handling: Unplug the heater and let it cool down for at least 15–20 minutes before removing it from the tank to prevent burns or damage. – Observe Indicator Lights: Red light indicates heating; green means the set temperature has been reached. If the unit flashes an error code, refer to the user manual for diagnostics.
