Specification: Condition: 100% Brand Item Type: Water Heater Material: PC, Copper Power: 110V: 3000W 220V: 4000W Frequency: 50 - 60HZ Remote Control Battery: 2 x AAA Battery (Battery Not Included) Weight: Approx. 1724g / 60.8oz Size: Approx. 24x13.5x6.5cm / 9.4x5.3x2.6in Wire Requirements: 2.5 copper core wire Air Switch Requirements: 25A Electricity Meter Requirements: electronic electricity meter 30A, mechanical electricity meter 20A Water Pressure Requirements: tap water basically meets the requirements, and booster pump can be added if it is too small. Operation Method: Press and hold the shutdown key, and after 6 seconds, it will automatically switch to gear mode, and then press 6 seconds to switch the frequency conversion mode. Advantages of frequency conversion mode: the machine only needs to set the temperature, and the system automatically changes the output power to the set temperature, making the operation more convenient and the setting more intuitive. Advantages of gear mode: the gear is 4 gears, and the fixed power of each gear is 1000 / 2000 / 3000 / 4000W, respectively P1 / P2 / P3 / P4, 1 to 4 gears. The gear can be controlled by people, the system does not need to calculate the power, and the low gear can be used in spring, summer and autumn. If the home wire is less than the specification of 2.5m copper core, the gear mode can be adopted, and the gear 1 to 3 can also meet the needs of ordinary washing, and the low gear can be used to control the power to prevent the wire from burning Package List: 1 x Water Heater 1 x Instruction Manual 1 x Remote Control (Battery Not Included) 1 x Remote Control Bracket 2 x Bag of Screw and Screw Sleeve
