How It Works

The Dosatron D25RE2VFII operates on a simple, water-powered principle, ensuring precise and consistent dosing without the need for electricity. As water flows through the unit, it activates a piston, which in turn draws a precise amount of concentrate from a separate container and injects it into the water line. This creates a homogeneous solution that is then discharged downstream.

1. Water Flow: Water enters the Dosatron unit.
2. Water Enters Body: The incoming water flows through the main body of the Dosatron.
3. Concentrate Pulled Up: A piston, driven by the water flow, pulls the concentrate from the solution container into the Dosatron.
4. Concentrate Mixes: The concentrate is precisely mixed with the incoming water inside the unit.
5. Blended Solution Discharged: The accurately blended solution is then discharged into the water line for distribution.

Installation and Setup

The Dosatron D25RE2VFII is designed for seamless integration into existing water systems. Its 3/4" NPT fittings allow for direct connection, minimizing installation complexity.

Pre-Installation Checklist:

• Ensure the water supply is turned off before beginning installation.
• Verify that the installation location provides adequate space for the unit and access for maintenance.
• Confirm that the water pressure and flow rate are within the specified operating ranges (4.3 to 85 PSI, 0.05 to 11 GPM).
• Have appropriate plumbing tools and sealing materials (e.g., thread sealant) ready.

Installation Steps:

1. Select Location: Choose a suitable location in your water line where the Dosatron can be easily accessed and is protected from extreme conditions.
2. Prepare Plumbing: Cut into the main water line where the injector will be installed. Ensure clean cuts and deburr any edges.
3. Apply Sealant: Apply appropriate thread sealant to the 3/4" NPT fittings of the Dosatron.
4. Connect Unit: Connect the Dosatron D25RE2VFII into the water line, ensuring the flow direction arrow on the unit matches the water flow. Tighten connections securely but do not overtighten.
5. Install Suction Tube: Place the suction tube into the concentrate solution container. Ensure the tube reaches the bottom of the container to maximize concentrate usage.
6. Check for Leaks: Slowly turn on the water supply and carefully inspect all connections for any leaks. Tighten as necessary.
7. Prime the Unit: Allow water to flow through the unit until it is fully primed and the concentrate begins to be drawn.

Operating Instructions

Adjusting Dosage:

The Dosatron D25RE2VFII features an adjustable dosage rate, allowing you to set the desired percentage of concentrate to be injected. This is typically done by rotating a collar or dial on the unit, which corresponds to the percentage or ratio markings.

• Identify the adjustment mechanism on your Dosatron unit.
• Rotate the adjustment collar/dial to align with the desired injection percentage (0.2% to 2%) or ratio (1:500 to 1:50).
• Ensure the setting is locked or secured if applicable, to prevent accidental changes.

Preparing Solutions:

Always prepare your chemical solutions according to the manufacturer's instructions for the concentrate. Ensure the solution is well-mixed and free of large particulates that could clog the injector.

Continuous Operation:

Once installed and primed, the Dosatron will continuously inject the set percentage of concentrate as long as water flows through it. Monitor the concentrate level in your solution container and refill as needed to ensure uninterrupted dosing.

Maintenance

Regular maintenance is essential to ensure the longevity and accurate performance of your Dosatron D25RE2VFII. The unit is designed to be durable and easy to service.

Routine Checks:

• Visual Inspection: Periodically inspect the unit for any signs of leaks, cracks, or damage.
• Suction Tube: Ensure the suction tube is clean and free of blockages. Clean or replace if necessary.
• Solution Container: Keep the concentrate solution container clean to prevent contamination and buildup.

Cleaning and Servicing:

For optimal performance, it is recommended to periodically clean the internal components and replace wear parts. Dosatron offers specific seal kits, rebuild kits, and maintenance tools for this purpose.

• Disassembly: Refer to the detailed service manual (not included here, but typically provided by Dosatron) for specific disassembly instructions.
