PRODUCT OVERVIEW
Complete salt chlorination for pool water
LASWIM EC Plus uses electrolysis to generate sanitizing chlorine from salt dissolved in pool water. Its controller and cell are integrated into one unit, reducing the installation footprint and the number of connection points. It suits small to medium pools, while regular testing and balancing of pool water remain necessary.

*Maximum pool volumes are manufacturer catalog reference figures for model selection. Allow approximately 20–30% extra output capacity and consider actual use, sun exposure, pump run time, and water quality. Check the model label and supplied adapter before installation.
Controls and protective functions
Choose 20%, 40%, 60%, 80%, or 100% to match the pool's chlorine demand.
Reverses cell polarity to help reduce scale on the cell plates. Continue to inspect the cell periodically.
Displays alert codes when abnormal conditions are detected. Consult the manual for the specific model to interpret each code.
INSTALLATION GUIDANCE
Installation points to check
Install in the pool return line downstream of the pump and filter, following the manufacturer's flow direction. If a bypass is used, provide suitable flow-control and isolation valves for the actual piping layout.
02 · Connection sizeCheck the 1.5 in / 50 mm unions against the piping before making permanent connections, and leave room to remove the cell for maintenance.
Use the power supply specified for the model and install residual-current protection in accordance with local requirements. Have a qualified person install it and check its interlock with the pump.
04 · Installation locationChoose a ventilated location and avoid rain, intense sunlight, and splashing as specified in the product manual.
Water and cell care
Measure free chlorine, pH, and actual salinity before adjusting output. The chlorinator does not automatically measure and control every water-quality parameter. If salt must be added, use pool-grade salt as specified in the manual and allow it to dissolve throughout the pool before generating chlorine.
Salt to add (kg) = Pool volume (m³) × [target salinity − measured salinity] (ppm) ÷ 1,000
Example: For a 50 m³ pool measuring 2,500 ppm with a target of 3,500 ppm, add approximately 50 kg. Measure again after the salt has dissolved and circulated.
Inspect the cell for scale on the maintenance schedule. Disconnect power, stop the pump, and release pipe pressure before removing any components. If cell-cleaning solution is required, follow the dilution and procedure in the supplied model's manual, wear protective equipment, and avoid scraping titanium plates with metal tools.
