4. Setup and Installation

  1. Submersion: Ensure the heater unit is fully submerged in water before connecting it to any power source. The entire heating element must be covered by water to prevent damage and ensure safe operation.
  2. Placement: Place the heater in an area of the tank with good water circulation. This helps to distribute heat evenly throughout the aquarium. Avoid placing it directly in front of a filter output or in a stagnant corner.
  3. Secure Attachment: Use the provided suction cups to securely attach the heater unit to the inside wall of the aquarium. Ensure it is firmly in place and cannot easily detach.
  4. Controller Placement: Mount the digital controller outside the tank using the provided controller bracket or hook. It is crucial that the controller remains dry and is not submerged in water.
  5. Power Connection: Connect the heater unit's cable to the digital controller. Then, plug the digital controller's power cord into a suitable electrical outlet.

5. Operating Instructions

Follow these steps to operate your MagTool Aquarium Heater:

  1. Power On: Once plugged in, the LED display on the digital controller will illuminate, showing the current water temperature (top display) and the set temperature (bottom display).
  2. Adjusting Temperature: To change the desired set temperature, press the button on the controller. Each short press will increase the set temperature by 1 degree. The temperature setting will cycle between 59°F and 93°F (15°C and 34°C).
  3. Temperature Unit Conversion: To switch between Fahrenheit (°F) and Celsius (°C), press and hold the button for approximately 5 seconds.
  4. Indicator Lights:
    • The red indicator light (HEAT) will be on when the current water temperature is below the set temperature, indicating that the heater is actively heating.
    • The blue indicator light (KEEP) will be on when the current water temperature has reached or exceeded the set temperature, indicating that the heater is not actively heating.
  5. Power Failure Memory: The controller is equipped with a power failure memory function. In the event of a power outage, the last set temperature will be retained once power is restored, eliminating the need for manual reconfiguration.

6. Safety Precautions

Adhere to the following safety guidelines to ensure safe operation and longevity of your MagTool Aquarium Heater:

  • Full Submersion: Always ensure the heater unit is completely submerged in water before plugging it into a power outlet. Operating the heater out of water will cause it to overheat rapidly, leading to damage and potential safety hazards.
  • Controller Dry: The digital controller is not waterproof. Keep it dry and away from water splashes or submersion.
  • Cool-Down Period: Before handling or removing the heater from the tank, always unplug the power cord and wait for at least 5 minutes to allow the heating element to cool down. The heater can be very hot immediately after operation.
  • Proper Placement: Place the heater in an open area within the aquarium to facilitate proper heat dissipation and prevent localized overheating.
  • Regular Inspection: Periodically inspect the heater unit, power cords, and controller for any signs of damage, cracks, or wear. Discontinue use immediately if any damage is observed and contact customer support.
  • Children and Pets: Keep the heater and its cords out of reach of children and pets to prevent accidental damage or injury.

7. Maintenance

Proper maintenance ensures optimal performance and extends the lifespan of your aquarium heater:

  • Cleaning: Regularly clean the heater unit to prevent algae or mineral buildup. Accumulation can reduce heating efficiency. Use a soft brush or cloth and aquarium-safe cleaning solutions if necessary.
  • Pre-Removal Cooling: As mentioned in safety precautions, always unplug the heater and wait at least 5 minutes for it to cool down before removing it from the water for cleaning or relocation.
  • Cord and Plug Check: Periodically check the power cord and plug for any signs of fraying, cuts, or damage. Never use a heater with a damaged cord or plug.

8. Troubleshooting

If you encounter issues with your MagTool Aquarium Heater, refer to the following troubleshooting guide:

Fault Code / SymptomExplanation / Solution
E1Heater running dry alert: The heating rod is not fully submerged in water.
Solution: Unplug the heater, ensure it is fully submerged, wait 5 minutes for it to cool, then plug it back in.
HHOver-temperature alert: The tank temperature has reached 94°F (35°C).
Solution: Check your set temperature. If the ambient temperature is high, consider methods to cool the tank. The heater will stop heating automatically.
"BB" SoundHeater not submerged: The heater is not fully submerged in water.
Solution: Same as E1. Unplug, submerge fully, cool, then restart.
Heater not heatingCheck if the red HEAT indicator light is on. Ensure the set temperature is higher than the current water temperature. Verify power connection.
Inaccurate temperature readingEnsure the temperature sensor (part of the heater unit) is in an area with good water flow and not obstructed. Compare with a separate, calibrated thermometer.
