Setup and Installation
The Fengind Salt Chlorine Generator features an all-in-one design for simplified installation. It connects directly into your pool's filtration system.
Pipe Connection
The unit is compatible with standard 1.5" (50mm) internal diameter pipes or 1.25"-1.5" (32mm-38mm) external diameter pipes using the provided universal adapters. Ensure a watertight connection.

Image: This image illustrates the two pipe interface sizes supported by the chlorinator: 1.5 inch (50mm) for internal water pipes and 1.25-1.5 inch (32mm-38mm) for external water pipes, highlighting the versatility of the universal adapters.
Installation Diagram
Refer to the diagram below for typical installation configurations. For internal pipe connections, if cutting an existing D50mm PVC pipe, the cut length must be 230mm. For external pipe connections, an additional 50cm pipe (not supplied) may be needed at the filter outlet, and installing a valve after the chlorinator is recommended for easier maintenance.

Maintenance
Regular maintenance ensures the longevity and efficiency of your salt chlorine generator.
Self-Cleaning Titanium Electrodes
The unit features self-cleaning titanium plates with automatic polarity reversal settings (4h/8h/12h) to prevent scale buildup. This significantly extends the cell's service life and reduces manual cleaning frequency.

General Cleaning
Periodically inspect the cell for any debris or excessive scale that may not be removed by the automatic cleaning cycle. If manual cleaning is required, refer to the detailed instructions in the full user manual. Always disconnect power before cleaning.
Troubleshooting
The chlorinator is equipped with advanced protection features and error codes to help diagnose issues. Below are common error codes and their solutions.
Error Codes and Solutions

Image: This image displays the chlorinator's screen indicating various error codes: F6 for High Salt (>5000ppm) with instructions to add water or hold the salt button; F2 for Low Flow (<2m³/h) with instructions to check circulation; and F5 for Low Salt (<2500ppm) with instructions to add salt or hold the salt button.
- F6 (High Salt): If the display shows F6 and salinity is above 5000ppm, add fresh water to the pool to dilute the salt concentration. Hold the Salinity button for 3 seconds to clear the alarm.
- F5 (Low Salt): If the display shows F5 and salinity is below 2500ppm, add pool salt according to your pool volume. Hold the Salinity button for 3 seconds to clear the alarm.
- F2 (Low Flow): If the display shows F2, it indicates insufficient water flow (<2m³/h). Check your pool pump and filtration system to ensure proper circulation.
