When your Zodiac Clearwater LM2 is installed, a measured quantity of salt is dissolved in the pool water to make it slightly salty.

Technical Details

  • The chlorine production of the Zodiac Clearwater LM2 is controlled by the number of hours the LM2 and filtration system is ON, as well as the setting of the output control. Power to this unit must be controlled by the pump timer. The chlorinator functions may only be set when the filtration system is running.
  • Includes a Super Chlorinate feature which automatically super chlorinates the pool for an approximated 24 hour period of pool pump operation.
  • Fitted with 3 indicator lights that monitor the operation of the chlorinator, the concentration of salt in the pool, and the water flow.
  • Designed to require minimum operator maintenance using reverse polarity technology to minimize the scaling of the cell.

How do I reset the circuit breaker?
With power off at the source, locate circuit breaker on bottom of unit near power cord. Push button in and turn on power. If power to transformer is not restored, replace circuit breaker.
My LM2 or LM3 will not operate.

After verifying that the pump is on and the unit is turned on, inspect for proper function. Often times a quick inspection will show that the chlorinator in fine and the problem is most likely in the water chemistry.

Check:
  1. Indicator lights: Are they functioning properly?
  2. Cell: Is it producing chlorine? (looks like effervescence)
  3. Cell connections:
    • LM2 - Is output cord attached to cell and blue sensor wire attached to sensor post?
    • LM3 - Is plug cap attached to cell?
  4. Cell: Is it reversing polarity properly? Calcium build-up on cell?
  5. Circuit breaker: Has it tripped?
  6. Controller: Turn off the power and remove chlorinator cover. Are there visible burn marks, signs of water damage, or loose wires or screws?
