Setup
- Unpack and Inspect: Carefully remove the heater from its packaging. Check for any visible damage to the heating element, cable, or controller. Do not proceed with installation if any damage is found.
- Mounting: Use the provided suction cups to securely attach the heating element to the inside wall of your aquarium. Ensure the heater is fully submerged in water.
- Optimal Placement: For the most accurate temperature control, position the heater horizontally near the water outlet or in an area with good water circulation. This helps distribute heat evenly throughout the tank.
- Controller Placement: Position the external controller in a dry location where it will not come into contact with water.
- Power Connection: Once the heater is securely installed and fully submerged, plug the power cord into a suitable electrical outlet (AC100-130V, 60HZ).
Operating Instructions
- Power On: After plugging in the heater, the display on the controller will illuminate, showing the current water temperature.
- Set Temperature: Press the 'SET' button on the controller to adjust the desired target temperature. Each press will cycle through the available temperature settings. Release the button when your desired temperature is displayed. The heater will automatically begin heating if the current water temperature is below the set temperature.
- Automatic Operation: The heater is thermostatically controlled. It will automatically turn on when the water temperature drops below the set point and turn off once the target temperature is reached, conserving electricity.
- Temperature Display: The controller continuously displays both the current water temperature and the set target temperature.
- Overtemperature Protection: The heater is equipped with an overtemperature protection feature to prevent overheating and ensure the safety of your aquatic life.
Maintenance
- Regular Cleaning: Periodically unplug the heater and remove it from the aquarium. Gently clean any algae or mineral deposits from the heating element using a soft brush or cloth. Do not use harsh chemicals or abrasive materials.
- Controller Care: Ensure the controller remains dry. Do not immerse it in water or wash it. Wipe with a dry cloth if needed.
- Cable Inspection: Regularly check the power cable for any signs of wear, cuts, or damage. Replace the unit if the cable is damaged.
Troubleshooting
- Error Codes (E1, E2, 04):
- If the display shows E1, E2, or 04 and does not return to normal operation, perform the following reset procedure:
- Hold down the controller button for 20 seconds. The display will show a flashing number (e.g., 66).
- Quickly press the button three times.
- Stop pressing. The display should show a new number (e.g., if it flashed 66, it should show 69).
- Wait 2 seconds for the heater to return to normal operation.
Note: If the display flashes 67, set to 70. If it flashes 68, set to 71, and so on.
- Heater Not Feeling Hot to Touch:
- The human body temperature is approximately 36°C (98.6°F). If the set aquarium temperature is lower than your body temperature, the water may feel cool to the touch, even if the heater is functioning correctly. Verify the temperature reading on the display against a separate aquarium thermometer for accurate measurement.
- Inaccurate Temperature Reading:
- Ensure the heater is placed in an area with good water circulation. Poor circulation can lead to localized temperature readings that do not reflect the overall tank temperature. Horizontal placement often provides higher accuracy.
