2. Safety Instructions
WARNING: Failure to follow these safety instructions may result in electric shock, fire, or serious injury.
- Full Immersion Required: The heating element must always be fully submerged in the liquid during operation. Operating the heater out of water will cause overheating and damage.
- Electrical Safety: Ensure the power outlet matches the heater's voltage (120V AC). Do not use with damaged cords or plugs. The power cable is UL-certified for safety.
- Leakage Protection: The device includes built-in leakage protection. If the circuit breaker on the plug trips, do not attempt to reset it repeatedly without checking for faults.
- Placement: Position the heater securely to prevent it from falling or touching the bottom/sides of the container, which could cause localized overheating.
- Children and Pets: Keep the heater out of reach of children and pets. Never leave the heater unattended when in use.
- Liquid Compatibility: This heater is designed for various liquids, including saltwater, chemicals, and groundwater, due to its titanium construction. However, always ensure the liquid is non-flammable and non-corrosive to the external components (controller, cables).
- Temperature Range: Do not exceed the maximum operating temperature of 240℉ (120℃).
- Disconnection: Always unplug the heater from the power source before handling, cleaning, or performing any maintenance.

3. Product Overview and Components
The Briidea 1500W Immersion Water Heater consists of three main parts:
- Titanium Heating Element: The submersible rod responsible for heating the liquid. Its titanium construction provides excellent corrosion resistance.
- Control Unit with LCD Display: This unit houses the thermostat, temperature sensor input, and the digital display for setting and monitoring temperature.
- Power Cord with GFCI Plug: Connects the unit to the power source and includes a Ground Fault Circuit Interrupter (GFCI) for enhanced safety.

4. Setup Instructions
- Unpack: Carefully remove all components from the packaging. Inspect for any signs of damage.
- Placement: Securely position the control unit on a dry, stable surface or mount it to a wall using appropriate fasteners (not included). Ensure it is easily accessible and away from direct water splashes.
- Immerse Heating Element: Place the titanium heating element into the liquid to be heated. Ensure the entire metal part of the heater, including the temperature probe, is fully submerged. The black cap where the cord connects should remain above the water line.
- Connect Power: Plug the GFCI power cord into a standard 120V AC electrical outlet. Press the 'RESET' button on the GFCI plug if necessary to ensure power is supplied.

5. Operating Instructions
- Power On: Once plugged in, the LCD display on the control unit will illuminate, showing the current liquid temperature and the last set temperature.
- Set Desired Temperature: Use the '+' and '-' buttons on the control unit to adjust the target temperature. The temperature range is 32℉ to 240℉ (0℃ to 120℃).
- Automatic Heating: The heater will automatically begin heating the liquid if the current temperature is below the set temperature. The 'ON' indicator on the display will light up.
- Temperature Maintenance: Once the desired temperature is reached, the heater will automatically turn off. It will restart if the liquid temperature drops below the set point, maintaining a consistent temperature.
- Memory Function: The control unit retains the last set temperature even after a power interruption.

6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your heater.
- Cleaning the Heating Element: Before cleaning, always unplug the heater and allow it to cool completely. Gently wipe the titanium heating element with a soft cloth to remove any mineral deposits or residue. Do not use abrasive cleaners or harsh chemicals.
- Inspecting Cords and Plugs: Periodically check the power cord and GFCI plug for any signs of damage, fraying, or discoloration. If damage is found, discontinue use immediately and contact customer support.
- Storage: When not in use, clean the heater, dry it thoroughly, and store it in a cool, dry place away from direct sunlight and extreme temperatures.
