3. Safety Instructions
- Always ensure the heater is completely submerged in water before turning on the power. Operating the heater out of water can cause damage and pose a safety risk.
- Before performing any aquarium maintenance, such as cleaning or water changes, always unplug the heater from the power outlet.
- Allow the heater to cool for at least 10 minutes after unplugging before removing it from the water.
- Do not bury the heater in sand or gravel. It must be fully immersed in open water.
- Ensure the power cord is not damaged or pinched.
- Keep out of reach of children.
4. Setup Instructions
- Unpack: Carefully remove the heater and all accessories from the packaging. Inspect for any damage.
- Mounting: Attach the two suction cups to the heater unit. Position the heater inside your aquarium, ensuring it is fully submerged in water. It can be installed vertically or horizontally.
- Placement: For optimal heat distribution, place the heater near an area with good water flow, such as near a filter outlet.
- Controller Placement: The external temperature controller should be placed outside the aquarium, in a dry location, where it is easily accessible for adjustments and viewing.
- Power Connection: Once the heater is fully submerged and properly positioned, plug the power cord into a suitable electrical outlet.

5. Operating Instructions
- Power On: After proper installation, plug the heater into a power outlet. The LED display on the external controller will illuminate.
- Set Temperature: Use the control button on the external controller to adjust the desired water temperature. The temperature range is 59°F to 93°F (15°C to 34°C).
- Switch Temperature Units: To switch between Fahrenheit (°F) and Celsius (°C), press and hold the control button on the top of the controller for 5 seconds.
- Monitoring: The LED display will show the current water temperature and the set temperature. When the heater is actively heating, a red indicator light will be constant. Once the set temperature is reached, the heater will stop heating, and a blue indicator light will be constant.
- Automatic Operation: The heater will automatically resume heating if the water temperature drops 1°F (1°C) below your set temperature.

6. Maintenance
- Cleaning: Before cleaning the aquarium or the heater, always unplug the heater and allow it to cool for at least 10 minutes.
- Heater Inspection: Regularly inspect the heater for any signs of damage, such as cracks in the glass or wear on the power cord. Discontinue use if damage is found.
- Water Circulation: Ensure good water circulation around the heater to prevent localized overheating and ensure even temperature distribution throughout the tank.
7. Troubleshooting
| Issue | LED Display | Possible Cause | Solution |
|---|---|---|---|
| Heater not heating, blue light on | Blue light constant | Set temperature has been reached. | No action required. Heater will resume heating if temperature drops. |
| Heater not heating, red light on | Red light constant | Heater is actively heating. | Allow time for the water to reach the set temperature. |
| Error Code E1 | Blue light and "E1" | Heater is not fully submerged in water or exposed to air. | Immediately unplug the heater. Ensure the heater is completely submerged before plugging it back in. |
| Overheat Protection | "HH" displayed | Water temperature exceeds 93°F (34°C). | Cut off power to the heater. Allow it to cool down to room temperature. Ensure good water circulation in the tank. Turn power on again. |
