For detailed diagrams and specific installation scenarios, refer to the Quick Start Guide.

5. Operating Instructions

The Dosatron D25F1 operates automatically once installed and water flow begins. It is a water-powered unit, meaning it uses the flow of water to draw and mix the concentrate.

• Fixed Ratio: The D25F1 is preset to a fixed dilution ratio of 1:100. This means for every 100 parts of water, 1 part of concentrate will be injected.
• Concentrate Preparation: Prepare your concentrate solution according to the manufacturer's recommendations, considering the 1:100 dilution ratio of the D25F1.
• Activation: Simply turn on your water supply. The Dosatron will automatically begin injecting the concentrate at the specified ratio as water flows through it.
• Monitoring: Periodically check the concentrate level in your supply tank and ensure the suction hose and strainer remain submerged.

6. Maintenance

Regular maintenance ensures the longevity and accurate operation of your Dosatron D25F1.

• Flushing: After each use, or periodically if used continuously, flush the unit with clear water to prevent residue buildup from concentrates.
• Strainer Cleaning: Inspect and clean the weighted strainer regularly to ensure it is free from debris that could impede suction.
• Seal Inspection: Periodically check all connections and seals for wear or damage. Replace worn components as necessary.
• Storage: If storing the unit for an extended period, ensure it is thoroughly flushed and drained. Store in a clean, dry place away from extreme temperatures.
