EQUIPMENT WATER PRESSURE HAZARD • Always turn pump off prior to installing or removing any Clearwater cell. Your pump/filter system is operated under pressure and the pressure must be released before you begin work. Please see your pump/filter owner’s manual for further instructions.
Testing Power Path 1 . Turn off power supply . 2 . Remove chlorinator from wall . 3 . Remove 4 screws to remove cover (support cover and leave ribbon wire connected to power PCB) . 4 . Turn on power supply . 5 .
Chlorinator Not Operating Are there any lights visible? Push On / Off Button See pg. 8. or turn on LM3 via controller Is the resettable circuit breaker tripped? Reset circuit breaker. Is there power at timer or switch? (see circuit breaker pg. 4) *If breaker continues to trip Refer customer to a qualified replace PC board (see pg.
No Chlorine Reading Are there any lights visible? See pg. 6. Will the output lights go all the way up? Chlorinator is working properly. Recommend 1. Is salt level 4000 ppm? to customer to have water sample checked by dealer. Add salt according to chart in Owner’s Manual.
Output Lights Will Not Go to 100% Is salt level 4000 ppm or higher? Add salt according to chart Check there is 220V incoming power. in Owner’s Manual. Have qualified electrician rewire chlorinator to 220V. Is water temperature below 65° F? Add salt to compensate.
Amber Output Light Blinking Press and hold service button Chlorinator is in a rest mode before it (located under the “C” in CLEARWATER) reverses polarity. Wait 5-10 minutes to speed up the reversing process. and check again.
No Flow Light Is On Is the pump moving water? Is the blue sensor wire attached There is a flow related problem and in good condition? with pool equipment. Disconnect sensor clip until pool equipment is repaired. Repair / attach blue sensor wire end to sensor on cell.
Add/Check Salt Light Is On Is salt level 4000 ppm or higher? Add salt according to chart in Owner’s Manual. Is water below 65 deg. F? Test touch pad PCB. Note: The LM3 may have the check salt (see touch pad PCB pg. 15) light on at low output.
Chlorine Reading too high Do the output lights go up and down? Check touch pad PCB. Reduce output setting. (see Touch Pad PCB pg. 15) Reduce pump run time. Remove blue sensor wire from cell to stop production for longer than one day at a time. LM3 - Disconnect plug cap.
1 . With power on, be sure chlorinator is NOT in super-chlorinate mode . 2 . Locate service button under the CLEARWATER Logo on LM2 model or above the “3” of LM3 logo . 3 . Press and hold service button down .
LM3 Interface Instructions Remove the LM3 power pack cover and connect the 4-conductor communication wire to the “eos com” terminal block on the LM3 control PCB, mounted in the LM3 cover . The wiring configurations for various controllers are as shown below: Polaris Eos Jandy Aqualink RS Pentair IntelliTouch...
After initialization for both the controller and the LM3, a software connection should have been made . A valid connection can be verified by observing the menu screen of the controller being used . If the chlorinator does not appear to have made a connection, try resetting both the LM3 and the controller .
PCB Replacement for the LM2-15 / LM3-15 When replacing a Clearwater LM2 or LM3 series PC board, please note that there is a difference between the models 15 and 24/40 . The LM2-15 or LM3-15 can be identified by either the label or the serial number .
PCB Replacement for LM2-24/3-24 or 2-40/3-40 1 . Disconnect power supply . 2 . Remove chlorinator from wall . 3 . Remove 4 screws to remove cover . 4 . Remove ribbon wire connector from power PCB and set cover aside . 5 .
Triac Screws The triac screws are the 3 screws at the base of the power PCB . It is imperative that these screws be tightened all the way . The triac tabs are used to transfer heat from the power PCB to the back panel of the chlorinator . If the triac screws are NOT tight, the power PCB will overheat and be damaged.
