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 allows the heater to be fully submerged. The water level should be more than 25 to 30 cm to allow the heater to float and remain suspended in the water. Adjust the power cord to position the heater correctly. If the water level is below 25 cm, ensure the heating element is fully submerged; slight tilting is acceptable. For inflatable pools, bathtubs, or containers made of sensitive materials, place a ceramic tile under the heating pipe 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 and observe bubbles around the heating element, indicating the heating process has started. For large volumes of water, unplug the device halfway through heating and check the temperature. When the desired temperature is reached, unplug the power, 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 during heating. Always unplug the device before touching the water. The stainless steel ball portion must remain fully submerged to prevent damage.
