Feature: 1. USE PRINCIPLE: It uses electrolysis to convert common salt (sodium chloride) into chlorine gas, which results in a cleansing effect on organisms in the water. It is a water treatment device for swimming pools and hot tubs. 2. COMPOSITION: Consists of an electrolytic cell and a control unit. In the electrolytic cell, salt ions (NaCl) in water are converted into chlorine gas (Cl2) and hydrogen gas (H2) by applying an electric current. 3. AUTOMATION: Simply add the proper amount of salt to the water (shipping without salt) and the salt chlorine generator will automatically control the electrolysis action, eliminating the need to manually add chlorinating agent. 4. HEALTHY, ECO FRIENDLY: Salt chlorine generators produce fewer chlorine by products, such as chlorates and trichloromethane, than conventional chlorinators, thus reducing potential harm to humans and the environment. 5. SMART CONTROL: You can manage your salt chlorinator through the for TUYA and for Smart Life APP, as well as through the control panel and display. 6. SELF ADAPTING OPERATION AND SALT SHORTAGE ALERT: The salt chlorinator adapts to reduce chlorine output when running low on salt. It also indicates the amount of salt required when there is a salt shortage. 7. SELF CLEANING FUNCTION: Has a self cleaning function that prevents calcium from accumulating on the titanium plate by automatically reversing the polarity. The reversal time can be up to 2, 4, 6 and 8 hours. 8. CHLORINE OUTPUT ADJUSTABLE AND BOOSTABLE WITH ONE BUTTON: Easily adjust chlorine production to your needs with the push of a button. Chlorine production can be easily accelerated to effectively eliminate microorganisms and decompose ammonia. 9. SAFETY MODE AND POWER FAILURE MEMORY: Automatically shuts off the water level when the salt chlorinator detects a low concentration to prevent damage to the unit. Automatically restores previous operating conditions when power is restored. Specification: Item Type: Pool Chlorinator System Material: Titanium Plate, ABS Recommended Salt Content (ppm): 2700-4500ppm Water Hardness: ≤200mg/L Water Temperature: 10-45°C Water Inlet And Outlet Diameter: 3.8cm / 1.5in, 50mm / 1.97in Product Size: Approx. 297.5x122x153mm / 11.7x4.8x6.0in Suitable For: Pool Cleaning, Circulation Integrated Control Equipment. Control Method: Control Panel, Display, For Smart Life Or For TUYA Smart. Package List: 2 x Connector1 x Adapter1 x Salt Chlorinator1 x Instruction Manual Note: Despite the many advantages of salt chlorine generators, they need to be inspected and maintained regularly to ensure proper operation and to keep the water clean. In addition, for swimming pools with excessively hard water, an acidic solution is required to adjust the alkalinity of the water.
