  • Page 6: Introduction

    INTRODUCTION BLH Salt water chlorination is a process that uses dissolved salt for chlorination swimming pools. chlorine generator uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already commonly used as sanitizing in pools. The BLH is designed for residential swimming pool up to 60,000 gallons (230,000 liters).

  • Page 7: Switches Of Control

    Switches of Control AUTO: Generally, if the BLH 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 P a g e...
  • Page 8 purpose of increased sanitation power. It's often necessary when the pool water is cloudy, free chlorine levels to fall below optimum levels. Switch to “ON”. It will work 100%, remember to back to “Auto” when you have desired chlorine. OFF: In “OFF” , the BLH stops outputting chlorine. NOTE: During the maintenance, please turn the power off the circuit breaker.

  • Page 9: Water Chemistry

    WATER CHEMISTRY For any pools, it is significant to maintain 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 14: Operation

    OPERATION By familiarizing yourself with the operation of the BLH 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 BLH will generate.
  • Page 15 POWER: Power illuminated, model is in power. 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.

  • Page 17 How to clean the cell? Important information: If there is severe mineral accumulation, more than one cleaning may be required to dissolve the remaining solids. After cleaning, carefully inspect the cell plate with bright light. If you see any remaining scale, debris or physical blocked in the salt cell, please repeat the cleaning process as needed.

  • Page 18: Installation

    5) Look inside the unit and check if there is no debris or scale residue. If necessary, repeat steps 2-4. 6) Re install the cell into the PVC return pipe. Note: If you do not currently have a cleaning cap or cleaning rack, you can fully immerse the cell in a five-gallon bucket.

Flow switch, confirm that the arrows on the flow switch (located on the side) point in the same direction of water flow. The Cell and Flow Switch cables have easy plug-in connectors in the control, the diagram below for the location of these connections.
  • Page 20 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.
