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 immersion heater into the water, ensuring the water level is sufficient to allow the heater to remain fully submerged. The water level should be more than 25 to 30 cm to ensure proper operation. The unit is designed to 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 if necessary. For inflatable 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 and observe small bubbles forming around the heating element, indicating the heating process has started. For large volumes of water, unplug the unit halfway through heating and check the temperature before continuing. When the desired temperature is reached, unplug the power first, wait 20 seconds, then remove the heater before using the water. Safety Notice: The metal heating tube must be fully submerged in water during operation. Never use the heater outside of water or while in contact with water. Always unplug the unit before touching the water. Do not allow human contact with water during heating. Unplug the device before removing the heater. The stainless steel ball portion must remain fully submerged during use to prevent damage.
