The Innowater SMC series is a range of salt water chlorinators designed for swimming pools, offering an efficient and automated solution for water disinfection. The device utilizes electrolysis to produce chlorine from salt or mineral additives in the pool water, ensuring crystal clear water with minimal maintenance.
Function Description:
The primary function of the Innowater SMC chlorinator is to generate chlorine for pool disinfection through the electrolysis of salt or mineral additives dissolved in the water. The system comprises a control unit, an electrolytic cell, and associated cabling. The control unit manages the chlorine production rate, monitors salt levels, and can automate pool pump operation. It offers both manual and automatic timer modes for flexible operation. A shock function is also available for rapid chlorine level recovery. The device incorporates a self-cleaning polarity change system to prevent calcium build-up on the electrodes, reducing the need for manual cleaning under normal conditions.

Usage Features:
The chlorinator is controlled via a four-key keypad and an LCD screen.
- ON/OFF Function: The chlorinator can be turned ON or OFF by holding the MENU key for 2 seconds. A safety delay of approximately 3 seconds is incorporated for the pump to stop, allowing the cell to be rinsed.
- Production Rate Adjustment: Chlorine production can be increased or decreased using the Ʌ or V arrows, controlled by varying the cell operating time in 10-minute periods (0% to 100%).
- Timer Mode (MAN/AUTO): Pressing the OK button for 2 seconds switches between manual (MAN) and automatic (AUTO) timer modes.
- In MAN mode, the pump runs constantly unless the chlorinator is switched OFF or production is set to 0%.
- In AUTO mode, the cell and pump operate according to a daily schedule programmed in the TIMER MENU, allowing for inactive periods.
- Shock Function: Activated by pressing Ʌ SHOCK for a few seconds from the production screen, this feature applies 100% chlorination for a selectable duration to quickly recover chlorine levels.
- Timer Menu: Allows programming daily working periods in 1-hour intervals for AUTO mode. Solid rectangles indicate ON hours, and empty rectangles indicate OFF hours.
- Language Menu: Provides options to select the display language.
- Polarity Period Adjustment: The factory-set polarity reversal period is 8 hours, recommended for preventing calcium build-up. This period can be adjusted (e.g., to less than 4 hours for increased cleaning frequency, or longer if less frequent cleaning is needed) to optimize cell life and performance based on pool conditions.
- TVI Readings: Displays temperature (T), voltage (V), and current (I) readings, useful for diagnosing potential issues.
- Date and Time Menu: Allows setting the current date and time.
- LCD Contrast Adjustment: Enables users to adjust the display contrast.
- Motor Protection Menu: A highly recommended safety feature that, when activated, stops the pool pump after a programmable delay (WI seconds) if no water flow is detected by the probe. If water is detected again, the pump restarts after a programmable delay (NO seconds).
Maintenance Features:
- Self-Cleaning Polarity Change System: Under normal conditions, this system automatically reverses polarity to eliminate calcium build-up on the electrodes, minimizing manual maintenance.
- Manual Cell Cleaning: If calcium build-up persists (e.g., in very hard water or old concrete pools), visual inspection and manual cleaning are required.
- Turn off the pump and chlorinator.
- Disconnect the power cable, unscrew the thread lock, and extract the cell.
- Immerse the electrodes (avoiding rods and cap) in a hydrochloric acid solution (1 part acid to 9 parts water) for no more than 5 minutes.
- Rinse the cell with freshwater, dry the terminal area, and reinstall.
- Important: Never scratch electrodes with metal objects, as their coating is fragile. Always add acid to water, not vice-versa, for safety.
- Water Preparation: Balancing pool water before starting the chlorinator is recommended. Maintain TDS between 3000-4000 ppm, pH between 7.2-7.6 (concrete) or 7.0-7.2 (fiberglass/vinyl), TA between 80-150 ppm, and Stabilizer between 30-50 ppm.
- Adding Salt/Minerals: The chlorinator must be OFF and the additive completely dissolved before operation to prevent irreversible damage to the cell and power supply. For new pool builds, wait four weeks before adding salt to cement-coated pools.
- Fault Messages:
- LOW WATER LEVEL IN CELL: Indicates insufficient water contact with the probe. Possible causes include a dirty filter, obstructed skimmer/pump basket, or an underpowered pump. Production stops until the water level is restored.
- SALT TOO LOW: Indicates mineral/salt concentration below optimal levels. Users should test water and add the required amount. This message can also appear due to low water temperature, bad electrical connection, or calcium build-up on electrodes.
- Warranty: The electrolytic cell and control unit are guaranteed for 3 years against manufacturing defects. The warranty is void if instructions are not followed, due to faulty electrical connections, accidental damage, water damage to the control board, pump operation without a bypass (for pumps >1.5V), acid poured into skimmers/cell without disconnecting the rectifier, acid tank near the chlorinator with insufficient ventilation, or operation with calcium build-up on electrodes.
