5. Setup Instructions
Follow these steps to properly install your HITOP aquarium heater:
- Unpack Contents: Carefully remove the heater, suction cups, and sticker thermometer from the packaging.
- Attach Suction Cups: Securely attach the two provided suction cups to the heater body. An extra suction cup is included for spare.
- Placement in Aquarium: Position the heater fully submerged in your aquarium. It can be installed horizontally or vertically. Ensure it is placed in an area with good water circulation to distribute heat evenly. Avoid placing it directly in the substrate.
- Secure Heater: Press the suction cups firmly against the inside glass of the aquarium to secure the heater in place.
- Install Thermometer: Attach the sticker thermometer to the outside of your aquarium glass, away from the heater, to monitor the water temperature.
- Drip Loop: Before plugging in, create a 'drip loop' with the power cord. This involves arranging the cord so that a section hangs below the electrical outlet, preventing water from running down the cord into the outlet.
- Connect to Power: Once the heater is fully submerged and secured, and the drip loop is in place, plug the heater into a suitable electrical outlet.

6. Operating Instructions
The HITOP aquarium heater features an adjustable thermostat for automatic temperature regulation.
- Set Desired Temperature: Rotate the adjustable knob at the top of the heater to select your desired water temperature. The temperature range is 68°F to 93°F (20°C to 34°C).
- Monitor Initial Heating: After setting the temperature, the heater's working indicator light will illuminate, signifying that it is actively heating the water. It may take several hours for the aquarium water to reach the set temperature, depending on tank size and ambient conditions.
- Automatic Regulation: Once the set temperature is reached, the heater will automatically turn off, and the indicator light will extinguish. The heater will cycle on and off as needed to maintain the water temperature within approximately ±2°F of your setting.
- Verify Temperature: Use the included sticker thermometer or a separate aquarium thermometer to verify the actual water temperature. Adjust the heater's knob slightly if the measured temperature differs from your desired setting.

- Inspection: Periodically inspect the heater for any signs of damage, such as cracks in the glass, frayed power cords, or loose connections. If any damage is observed, discontinue use immediately and replace the heater.
- Water Changes: Always unplug the heater and allow it to cool before performing water changes that might expose the heater to air.
