Usage Tips:Why you need it: City water and tap water normally used contain minerals such as calcium and magnesium ions, which may produce insoluble polymers such as calcium carbonate during transportation. After precipitation, they adhere to the pipe wall to form scale, clogging the pipes, reducing the heating effect of the equipment, rust accumulation and unpleasant odor.Unlike salt water softeners:No salt is added, no chemicals are introduced into the water, and the PH value is not . Maintains the normal minerals in the water while preventing scale formation and the decomposition and discharge of existing scale.Easy to install: No need to damage pipes, just wrap the coil around the outside of the pipe. Suitable for all kinds of pipes. This water descaling system should be installed on the main water supply pipe where the water enters the building to maximize the effect.Working Principle: By transmitting complex FM electromagnetic signals into the water, when the water flows through area, the decomposed water molecules better combine with calcium and magnesium ions to form crystal particles with smooth surfaces, which are less likely to be attached to the surfaces of pipes and equipment. It also allows existing scale to decompose slowly.Unlike salt water softeners] No salt is added, no chemicals are introduced into the water, and the PH value is not . Maintains the normal minerals in the water while preventing scale formation and the decomposition and discharge of existing scale.Colour:As ShownMaterial:plasticPlug Type:US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the , the Philippines and so on.voltage: AC110V-120V[Note]High iron content in the water reduce the effect of the electronic water descaler. For iron content in water higher than 0.3ppm, it is recommended to use an iron removal filter.Package Contents:1 * Electronic Water Descaler SystemOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
