2. Montáž: Mount the Dosatron vertically in a bypass or inline configuration, ensuring it is easily accessible for adjustments and maintenance.
3. Vodovodní přípojky: Connect the water inlet (marked) to your main water supply and the outlet to your distribution system. The unit features 1 1/2 inch male thread water connections. Use appropriate fittings and sealants to prevent leaks.
4. Suction Tube Connection: Connect the suction tube to the dosage adjustment mechanism at the bottom of the unit. Ensure the other end of the suction tube is placed into the liquid concentrate container.
5. Základní nátěr: Before operation, ensure the unit is properly primed by allowing water to flow through it until all air is purged from the system and the suction tube.

Note: It is recommended to install a filter upstream of the Dosatron to protect it from particulate matter in the water supply.

4. Návod k obsluze

The Dosatron D8RE3000VF is designed for straightforward operation. Follow these steps to adjust and maintain your desired dosage.

1. Setting Dosage Rate: The desired dosing rate (0.03% - 0.125%) can be easily set by rotating the adjustment ring located at the bottom of the unit. Align the indicator with the desired percentage on the scale.
2. Spuštění provozu: Once the dosage rate is set and the concentrate container is in place, slowly open the water supply valve to allow water to flow through the Dosatron. The unit will begin to draw and mix the concentrate proportionally.
3. Sledování: Periodically check the concentrate level in your container and the output mixture to ensure consistent operation.
4. Zastavení provozu: To stop dosing, close the water supply valve to the Dosatron.

Important: Do not operate the unit dry. Always ensure water is flowing through the unit when it is in operation.

5. Údržba

Regular maintenance ensures the longevity and optimal performance of your Dosatron D8RE3000VF.

• Máchání: After each use or when changing concentrates, it is recommended to rinse the Dosatron by running clean water through it for several minutes with the dosage set to 0% (or minimum setting) to flush out any residual chemicals.
• Inspekce: Periodically inspect the suction tube, seals, and connections for wear, cracks, or leaks. Replace any damaged components immediately.
• Čištění: If the unit's performance degrades, it may require internal cleaning. Consult a qualified technician or the manufacturer's service guidelines for detailed cleaning procedures.
• Zima: If the unit is to be stored in freezing temperatures, ensure it is completely drained of water to prevent damage from ice expansion.
