4. Setup and Installation
- Unpack: Carefully remove all components from the packaging. Inspect for any damage.
- Placement: Position the heater in the liquid container. Ensure the entire titanium heating element is fully submerged. The water level must be above the minimum immersion line marked on the heater.
- Sensor Placement: Place the temperature sensor into the liquid. For accurate readings, ensure the sensor is also fully submerged and not directly touching the heating element or the container walls.
- Controller Mounting: Mount the digital controller in a dry, accessible location, away from direct splashes.
- Power Connection: Plug the heater's power cord into a standard 120V AC grounded electrical outlet. Ensure the outlet is suitable for the 1500W power draw.
5. Operation

Figure 5.1: The Briidea Immersion Heater operating in a bathtub, demonstrating its built-in thermostat for automatic shut-off, which helps save time and energy by maintaining a set temperature.
- Power On: Once plugged in, the LCD screen on the controller will illuminate, displaying the current liquid temperature and the previously set temperature.
- Set Temperature: Use the '+' and '-' buttons on the controller to adjust the desired temperature. The temperature range is 32°F to 240°F (0°C to 120°C).
- Automatic Heating: The heater will automatically begin heating the liquid until the set temperature is reached. Once the target temperature is achieved, the heater will automatically shut off.
- Temperature Maintenance: The heater will monitor the liquid temperature via the submerged sensor. If the temperature drops below the set point, the heater will automatically reactivate to maintain the desired temperature.
- Memory Function: The controller features a power-off memory function, retaining your last set temperature even if power is interrupted.
6. Maintenance
- Cleaning: Disconnect the heater from power and allow it to cool completely before cleaning. Wipe the titanium heating element with a soft cloth to remove any mineral deposits or residue. Do not use abrasive cleaners or harsh chemicals.
- Inspection: Regularly inspect the power cord, plug, and heating element for any signs of damage, wear, or corrosion.
- Storage: When not in use, clean the heater thoroughly, dry it, and store it in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
- Heater Not Turning On: Check if the power cord is securely plugged into a functional outlet. Verify that the leakage protection has not been triggered.
- Liquid Not Heating: Ensure the heating element is fully submerged. Check if the set temperature is higher than the current liquid temperature.
- Inaccurate Temperature Reading: Ensure the temperature sensor is fully submerged and not obstructed or touching the heating element directly.
- Leakage Protection Activated: If the leakage protection trips, immediately unplug the heater. Inspect the unit for any visible damage or water ingress into the electrical components. Do not use if damage is found.
