ABS engineering plastics, high temperature resistant, soft and strong, not easy to burst high shape stability. Strong anti-stamping, UV radiation, so the product is not easy to aging security is more durable and lasting. Water consumption information: Under the condition of 0.1MPa water pressure The maximum flow of hot water is 2.4L/ min, and the maximum flow of cold water is 3L/ min.It may not be possible to maintain a large flow of water. Before purchase, please make a clear distinction between Below Inflow and Lateral Inflow to avoid unusable conditions. Big Under Bend, Small Under Bend, Big Lateral Bend, Small Lateral Bend. 3 to 5 seconds fast heat. In general, to say at least, the temperature at about 20 degrees to 40 degrees in winter & 30 degrees to 50 degrees in summer, depending on the quantity of flowing water. Vertical upward installation is required, not inclined or inverted installation. For the first time, please turn on the cold water and then the power supply. It is strictly forbidden to install the water purifier, water purifying faucet, and other blocking original parts, so as to avoid affecting the normal outflow of the machine and hindering the heating of the machine, thereby damaging the machine.
