3500W Electric Water Heater Stainless Steel Automatic Immersion Heater 220V 3500W. Features: Suitable for plastic barrels, bath barrels, bathtubs, swimming pools, fish tanks, barrels, buckets, and other water-filled containers. Submerge the water heater completely in water, ensuring the water level is at least 25 to 30 cm deep. The device will naturally float on the surface; adjust the power cord to position the heater properly. If the water level is below 25 cm, ensure the heating element is fully submerged. The heater can be slightly tilted for use if necessary. For inflatable pools, bathtubs, or containers made of sensitive materials, place a ceramic tile under the heating pipe to prevent direct contact. Fill the container with water, place the heater in, and plug in the power. Wait for the indicator light to turn on and observe small bubbles forming around the heating element, indicating heating has started. For large volumes of water, unplug the unit halfway through heating to check water temperature. Once the desired temperature is reached, unplug the power, wait 20 seconds, then remove the heater before using the water. Warning: 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. Do not touch the water during heating. Always unplug the unit before handling. The stainless steel heating element must remain fully submerged to avoid damage.
