Specification: Item Type: Immersion Water Heater Material: Stainless Steel, Brass, Silicone Uses: Widely Used in Various Heating Conditions Working Voltage: AC 240V Installation Thread: 1"NPT Product Length (Excluding Base Connection Column): 2500W: Approx. 280mm / 11.0in 3500W: Approx. 300mm / 11.8in 4500W: Approx. 300mm / 11.8in 5500W: Approx. 360mm / 14.2in. Package List: 1 x Immersion Water Heater Note: 1. The components should be stored out of dryness. If the insulation resistance drops below 1 megohm due to long‑term storage, they can be dried in an oven at about 200°C for several hours (or pass the components under low pressure for several hours) to restore the insulation resistance.2. When carbon buildup is found on the surface of the tube, it must be removed before use, so as not to reduce the efficiency or even burn out the components.3. When melting bitumen, paraffin and other solid oils, the voltage should be lowered, and the voltage should be increased to the rated voltage after melting to prevent the concentration of electricity from reducing the service life of the components.
