The Ozone Line Tubing has two check valves fitted, which prevent water from flowing back into the system.

Your Mineral Swim Control Unit should also have a Drain Valve fitted to protect it from any backflow.

• Every 12 months, or
• Immediately, if you can see any water dripping from the drain valve.

1. Turn off the system
2. Locate the Ozone Line Tubing
3. Remove the Tubing (push the sliding sleeve/ring of the quick connectors) at both ends.

Dry End - From the nozzle at the bottom right of the flood valve.

Wet End - Nozzle on the cone in the injector inlet.

4. Insert the new Ozone Line Tubing in the same direction.

5. Ensure the Ozone Line Tubing is connected on its designated side to maintain the correct ozone flow direction. A small label identifies the control unit end and the wet end (check the flow arrow on the Check Valve is pointing towards the pool/spa line).

6. Reconnect the tubing to both ends securely.

7. The Ozone Line Lubing (and Check Valves) are now replaced and protected from water backflow.

1. Locate the check valve on the ozone line.

2. Remove the tubing from both ends (a gentle twist may help).

3. Insert the new Teflon check valve in the same direction (check the flow arrow is pointing towards the pool/spa line).

4. Reconnect the tubing to both ends securely.

5. Your check valves are now replaced and the system is protected from water backflow.

Yes. Although the system has automatic reverse polarity cleaning, you should periodically inspect the cell and clean it if calcium or other deposits are visibly built up on the plates.

Test your pool water regularly; your local Elite Dealer can assist. For properly balanced water, the chemicals should be within the following recommended ranges:

• Chlorine: 1–3 ppm
• pH: 7.2–7.4
• Hardness: 150–350 ppm
• Cyanuric Acid (CA): 30–50 ppm
• Total Alkalinity (TA): 80–120 ppm
• Phosphates: 0–300 ppb
