3500W Electric Water Heater Stainless Steel Automatic Immersion Heater 220V Features: Suitable for plastic barrels, bath barrels, bathtubs, swimming pools, fish tanks, barrels, buckets, and other water-filled containers. Place the heater into the water, ensuring the water level is sufficient to allow the unit to float and remain suspended. The water depth should be more than 25 to 30 cm. The product will automatically float on the surface; adjust the power cord to position the heater correctly. If the water level is below 25 cm, ensure the heating element is fully submerged. The heater can be slightly tilted for proper submersion. For inflatable swimming pools, bathtubs, or containers made of sensitive materials, place a ceramic tile under the heating tube to prevent direct contact and potential damage. Fill the container with water, insert the heater, and plug in the power. Wait for the indicator light to turn on. When small bubbles appear around the heating tube, the heating process has started. For large volumes of water, unplug the device halfway through heating and check the temperature before continuing. Once the desired temperature is reached, unplug the power first, wait 20 seconds, then remove the heater before using the water.
