Introduction
The HydroMaster™ Model 208 is a versatile drum or wall-mounted proportioner designed to automatically mix liquid concentrates with water. This non-electric, water-powered system dispenses the diluted solution into any container, ensuring consistent and accurate dilution ratios. It eliminates the variability of manual mixing, enhancing the performance of your concentrated cleaning products, coolants, or fertilizers.
This mixer utilizes the Venturi principle, where water passing over an orifice creates suction to draw concentrate from its container, mixing it with the water. Concentration is adjusted by changing the metering tip size. The HydroMaster™ Model 208 is ideal for various applications including all-purpose cleaners, strippers, degreasers, soluble oil, synthetic coolants, and fertilizers.
Important Safety Note: These units cannot operate with any back pressure. They are designed to fill a pail or nearby container and cannot be used with any type of sprayer or shut-off valve on the discharge side. The outlet hose must NOT be connected to any device that can restrict the flow.
Setup
Before setup, ensure you have all components: the proportioner unit, 4 ft. suction tube with foot valve, 4 ft. discharge tube, and the set of 14 metering tips.
Mounting Options
- Drum Mount: The unit can be directly mounted onto a standard drum. Ensure the mounting is secure and stable.
- Wall Mount: Alternatively, the unit can be securely mounted to a wall using appropriate fasteners (not included). Choose a location near a water source and the concentrate container.

Connecting Water Supply
Connect a standard water hose to the inlet of the proportioner. Ensure a backflow preventer is installed in accordance with local regulations, as this is required in some areas.
Connecting Suction and Discharge Tubes
- Insert the 4 ft. suction tube with the foot valve into your concentrate container. The foot valve should rest at the bottom of the container to ensure continuous draw.
- Attach the 4 ft. discharge tube to the outlet of the proportioner. This tube will direct the diluted solution into your desired container (e.g., a pail).

Selecting Metering Tip
The HydroMaster™ Model 208 comes with 14 metering tips, allowing for mix ratios from 0.9% to 50%. Select the appropriate metering tip based on the desired dilution ratio for your concentrate. Insert the chosen tip into the designated slot on the proportioner. Refer to your concentrate's instructions for recommended dilution ratios.

Operating Instructions
- Ensure the concentrate container has sufficient product and the suction tube is fully submerged.
- Position the discharge tube into the container you wish to fill with the diluted solution. Remember, this container must not create any back pressure.
- Slowly turn on the water supply to the HydroMaster™ unit. Water flow will activate the Venturi mechanism, drawing the concentrate and mixing it.
- Monitor the filling process. Once the desired volume is reached, turn off the water supply.
- Always ensure the discharge hose is free and clear, allowing for unrestricted flow. Never kink, block, or attach a sprayer/valve to the discharge hose.
Caution: Accuracy of dilution can be affected by water pressure and the level of concentrate in the container. Maintain consistent water pressure for optimal performance.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your HydroMaster™ Model 208.
- Rinsing: After each use, especially when changing concentrates, run clean water through the unit for a few minutes to flush out any residual chemicals.
- Check Hoses and Connections: Periodically inspect the suction and discharge tubes for kinks, cracks, or blockages. Ensure all connections are secure and free from leaks.
- Foot Valve Inspection: Check the foot valve at the end of the suction tube for debris that might impede concentrate flow. Clean if necessary.
- Storage: When not in use for extended periods, disconnect the unit from the water supply and store it in a clean, dry place, away from extreme temperatures.
Troubleshooting
If you encounter issues with your HydroMaster™ Model 208, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No concentrate drawn / Weak dilution |
|
|
| Excessive dilution / Too strong solution |
|
|
| Water leaks from unit |
|
|
If problems persist after attempting these solutions, please contact Hydro Systems customer support for further assistance.
