1. Introduction
This manual provides instructions for the FREESEA 50 Watt Aquarium Submersible Betta Heater and its accompanying digital thermometer. This heater is designed to maintain stable water temperatures in 5-15 gallon betta fish or turtle tanks. It operates on 110-120V and features a 5.0ft power cord for convenient indoor use. The heater is constructed with a rubber sealing layer for enhanced safety and durability, preventing water leakage. Its quartz glass construction further contributes to its robust design.
The adjustable temperature range is 63-95°F, allowing precise control over your aquarium's environment. The included digital thermometer provides real-time water temperature readings.

2. Included Components
- FREESEA 50 Watt Submersible Aquarium Heater
- Digital Thermometer with Suction Cup
- Suction Cups for Heater Mounting
3. Setup Instructions
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect the heater and thermometer for any signs of damage. Do not use if damaged.
- Heater Placement: Attach the heater to the inside wall of your aquarium using the provided suction cups. Ensure the heater is positioned horizontally or vertically in an area with good water circulation.
- Full Submersion: Crucially, ensure the heater is 100% submerged in water before plugging it into a power outlet. Operating the heater out of water can cause damage and pose a safety risk.
- Thermometer Placement: Attach the digital thermometer to the aquarium wall, preferably on the opposite side of the heater, to get an accurate average water temperature reading. Ensure the thermometer probe is fully submerged.
- Power Connection: Connect the heater's power cord to a suitable 110-120V power outlet. The power outlet should have a leakage disconnect switch and a broken circuit switch for safety.

4. Operating Instructions
- Setting Temperature: The heater features an adjustable knob on the top. Turn this knob to select your desired temperature within the 63-95°F range. Refer to the markings on the knob for temperature guidance.
- Monitoring Temperature: Use the included digital thermometer to monitor the actual water temperature. The thermometer provides a clear LED display. Compare the thermometer reading with your set temperature.
- Heater Indicator Light: When the heater is actively heating, an indicator light inside the heater will illuminate. Once the water reaches the set temperature, the heater will automatically turn off, and the indicator light will extinguish. It will reactivate when the temperature drops below the set point.
- Initial Adjustment: After initial setup, allow several hours for the water temperature to stabilize. You may need to make minor adjustments to the heater knob over the first 24-48 hours to achieve your precise desired temperature, as indicated by the digital thermometer.
