  • Page 5: Introduction

    INTRODUCTION HydroSalt™ Salt water chlorination is a process that uses dissolved salt for the chlorination of swimming pools. The HydroSalt™ chlorine generator uses electrolysis in the presence of dissolved salt to produce chlorine gas or dissolved forms, hypochlorous acid and sodium hypochlorite, which are already commonly used as sanitizing in pools.
  • Page 6 AUTO: Generally, if the HydroSalt™ is in “Auto”, it will automatically work according to the chlorine output settings. SUPER CHLOR: The “Super Chlor” function is the process of temporarily increasing the free chlorine levels in the pool for the purpose of increased sanitation power. It's often necessary when the pool water is cloudy, free chlorine levels to fall below optimum levels.
  • Page 7: Water Chemistry

    WATER CHEMISTRY For any pools it is mandatory to mountain proper water chemistry of the pool water, including pH, calcium levels, and alkaline content, especially to maintain proper levels of salt and stabilizer. It helps to prevent corrosion or scaling and to bring better experience for pool users.
  • Page 8 Use the table below to help determine the amount of salt and pool size. The ideal salt level is between 3200-3400 ppm. How to calculate your pool size in Gallons: Rectangular Pools: Length(feet) x width(feet) x average depth(feet) x 7.5 Circular Pools: Diameter x diameter x average depth x 5.9 Oval Pools:...
  • Page 9 salt (also called water conditioner) Granules are an economical way to buy large amounts of salt. However, only NaCl salt with a purity of at least 99% can be used. The pill is a compressed form of evaporated salt and may take longer to dissolve. Avoid using salt with an anti-caking agent, which may cause discoloration.

  • Page 12: Operation

    OPERATION By familiarizing yourself with the operation of the HydroSalt™ generator, you can achieve maximum performance for your pool. When chemical levels are in the recommended range, there are FOUR factors that you can control. Filter time each day, amount of salt in the pool, the output of chlorine you set, and stabilizer level in the water will directly impact the amount of chlorine the HydroSalt™...
  • Page 13 GENERATION: Model in normal operation, the LED will be steady. If it is flashing, check the pool water chemicals. SUPER CHLOR: The generator runs at 100% capacity which can produce enough chlorine to clear up moderate cloudiness, but the generator is forced to overwork. It will be automatically switched to the original output after 24- hour SUPER CHLOR operation.

  • Page 15 Spring Start-up When reopening the pool after long term, check all water chemistry before power on the HydroSalt™. Maintenance When checking other water chemistry levels, always monitor the salinity level of the swimming pool. After the system runs for a period of time, it will eventually need to clean the cells due to the scaling of natural minerals.
  • Page 16 1) Turn off all power sources of all swimming pool equipment and close the water supply line valve (if applicable). 2) Unplug the cell cable connecting to the control box. 3) Loosen the threaded ring around the joint at the junction of the pool and the pipes.

    INSTALLATION Before installation, make sure all the water chemistry is in normal range. Using 2-inch pipes and should be performed by qualified personnel in case there is a 1.5-inch pipe, a reducer can be used to fit the system; be sure to pay attention to any changes. Check each measurement carefully before cutting.
  • Page 18 Plumbing These instructions apply to 2-inch pipe (typical). Make sure to choose with existing pool pipe size (1.5 inches or 2 inches), and discard other unnecessary joints. For articulated connections, you will also use the included 2" to 1.5" reducer bushing to accommodate the flow switch. For 1½" installations, be sure to pay attention to any new or other measurements before cutting the tube.
