How It Works

Using the process of saltwater electrolysis, the SMT120 converts a small amount of dissolved salt into chlorine. As pool water flows through the electrolytic cell, a low-voltage current activates the high-efficiency plates, releasing chlorine that immediately dissolves into the water for continuous sanitization. This automated process helps maintain steady chlorine levels while reducing the need for manual chemical adjustments.

Installation

Pre-Installation Preparation:
Read the user manual and gather essential tools. Ensure your pool water meets the minimum salt level (4000–5000 ppm) and that your pump and filtration system are operating correctly.

Power Pack Setup:

• Location: Choose a well-ventilated, sheltered spot near your pool equipment.

• Mounting: Secure the power pack using the provided bracket at least 1–1.5 meters above ground level to protect it from splashes.

• Electrical Connection: Plug the power pack into a nearby 240V outlet with a 3A circuit breaker to ensure safe power delivery.

Electrolytic Cell Installation:

• Positioning: Install the cell as the last component in your pool’s plumbing—after the filter and before the return line—to maximize chlorine distribution.

• Orientation: Ensure the cell is installed horizontally so that the gas trap functions properly, keeping the cell fully submerged during operation.

• Plumbing: Connect the cell using standard 40mm or 50mm pressure pipes. Use adapters if necessary and verify that all connections are secure and leak-free.

Connecting the Power Leads:

• Connect the cell’s lead cable to the junction box on the underside of the power pack, ensuring proper color matching as specified.

• Replace the junction box cover to protect the electrical connections.

Commissioning:

• With all components securely installed, power up the system. Check that the built-in timer functions correctly.

• Set the timer to your preferred schedule and verify that both the pump and chlorinator operate in sync.

• After initial startup, monitor your pool’s water chemistry to ensure the system is performing as expected.

Maintenance and Operation Tips

Regular Water Testing and Chemical Balance

• Weekly Pool Chemistry Checks:

• Salt Level: Ensure your pool’s salt concentration remains within the ideal range of 4000–6000 ppm (with 5000 ppm being optimal). Although the RP20 is over-salt protected, consistently low salt levels (<4000 ppm) can reduce chlorine production.

• pH & Alkalinity: Maintain a pH between 7.2 and 7.6 and total alkalinity around 80–120 ppm. Proper pH ensures that chlorine is more effective and helps prevent scale formation on the cell.

• Free Chlorine: Aim for a free chlorine level of 1.5–3.0 ppm. Adjust the chlorine output or running hours if levels are too low; if necessary, perform a manual super-chlorination to raise the level quickly.

• Stabilizer (Cyanuric Acid):

• Keep stabilizer levels between 40–80 ppm. Adequate stabilizer helps protect chlorine from being broken down by sunlight, thereby reducing the overall run time of the chlorinator.

Inspection and Cleaning of the Electrolytic Cell

• Self-Cleaning Feature:

• The RP20 is designed with an automatic self-cleaning cell that periodically reverses its polarity to shed calcium and other deposits. This reverse polarity function minimizes the need for manual cleaning under normal water conditions.

• Periodic Inspection:

• Even with the self-cleaning mechanism, it is important to visually inspect the clear cell housing every few months. Look for any noticeable calcium build-up or “dirty” electrodes that might indicate that the self-clean cycle isn’t sufficient.

• If your pool water has high calcium hardness or if you notice a gradual decline in chlorine output, consider increasing the frequency of manual inspections.

• Manual Cleaning Procedure (if required):

• Safety First: Always disconnect the power to both the chlorinator and the pool pump before inspecting or cleaning the cell.

• Removal: Carefully unscrew and remove the cell from its housing. Check the electrode plates for white scale deposits.

• Cleaning: If deposits are present, soak the electrode in a recommended cell cleaner solution (available at pool supply stores) for 5–10 minutes. Agitate gently to help dislodge stubborn scale.

• Rinse and Reassemble: Rinse thoroughly with fresh water and apply a small amount of silicone-based lubricant to the cell o-ring before reassembling. This will ensure a proper seal and prevent leaks.

Operational Settings and Routine Use

• Timer Settings:

• The “set and forget” timer ensures your pool is sanitized automatically—just check periodically to confirm settings remain as desired.

• Chlorine Output Adjustment:

• Use the adjustable chlorine control to set the output according to your pool’s needs. Factors such as weather, pool usage, and water temperature might necessitate adjustments.

• Monitor the chlorine output indicator on the control panel to confirm that the system is operating within the desired range.

Safety and Operational Checks

• Flow Sensor Verification:

• The RP20 includes a flow-sensitive switch that stops chlorine production if there’s insufficient water movement. Regularly ensure that the pump is running properly and that there are no blockages in your filtration system.

• Overload and Oversalt Protection:

• The built-in safety features automatically protect the unit from electrical overload or excessive salt levels. However, periodic checks of these features (via the system’s indicators) can prevent future issues.

• Regular Maintenance of External Components:

• Ensure that the power pack and all connections are free from corrosion or loose wiring. Keep the power pack in a well-ventilated, dry area away from corrosive pool chemicals.

Seasonal Considerations

• Summer and High-Usage Periods:

• During periods of heavy pool use or extreme heat, the chlorinator may need to run for longer durations to maintain chlorine levels. Monitor your pool’s free chlorine and adjust the timer settings accordingly.

• Off-Season/Winter:

• When pool usage is reduced, you can scale back the operating time. However, it is advisable to occasionally run the system to prevent stagnation and algae growth. Ensure that water chemistry is still maintained to avoid any premature cell scaling.

Documentation and Follow-Up

• User Manual and Technical Support:

• Always refer to the Saltmate RP20 user manual for the latest maintenance guidelines and troubleshooting tips.

• If you encounter persistent issues or significant scaling, consult with a pool maintenance professional or contact Saltmate customer support.

By following these comprehensive maintenance and operation tips, you’ll ensure that your Saltmate RP20 Self Clean Chlorinator remains efficient, extends its service life, and continues to provide your pool with crystal clear, sanitized water throughout the swimming season.
