4. Setup and Installation
4.1 Unpacking
Carefully remove the pump and all accessories from the packaging. Inspect for any signs of damage during transit. Retain packaging for future transport or storage.
4.2 Mounting
Mount the pump securely on a stable, vertical surface using appropriate fasteners. Ensure the mounting location allows for easy access to connections and controls, and is protected from direct sunlight or extreme temperatures.
4.3 Electrical Connection
Connect the pump to a standard power supply (230 V or 120 V, as per model specification). Ensure the power source matches the pump's requirements. Use a dedicated circuit if possible to avoid interference.
4.4 Fluid Connections
- Connect the suction line (inlet) from the chemical reservoir to the pump's inlet port. Ensure the suction line is submerged and free of air bubbles.
- Connect the discharge line (outlet) from the pump's outlet port to the injection point in your system.
- Secure all connections with appropriate fittings to prevent leaks.
4.5 Priming the Pump
Before initial operation, the pump head must be primed to remove any air. Follow the specific priming procedure outlined in the pump's on-screen menu or dedicated priming button, if available. This typically involves running the pump at a high stroke rate until a steady flow is observed.
5. Operating Instructions
5.1 Power On/Off
To power on, connect the pump to the electrical supply. The display will illuminate. To power off, disconnect from the electrical supply.
5.2 Control Panel Navigation
The control panel features a digital display and several buttons:
- ESC: Used to exit menus or cancel an operation.
- OK: Used to confirm selections or enter menus.
- +: Used to increase values or scroll up.
- -: Used to decrease values or scroll down.
5.3 Setting Flow Rate
Navigate through the menu using the ESC, OK, +, and - buttons to access the flow rate setting. Adjust the desired flow rate (e.g., in liters/hour) according to your application requirements. Confirm the setting with the OK button.
5.4 pH/Rx/CL Control (If Applicable)
For models with pH, Rx, or CL control capabilities, connect the respective probes to the designated ports. Access the control menu to set desired setpoints, hysteresis, and alarm limits. The pump will automatically adjust dosing based on real-time sensor readings.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dosing pump.
6.1 Cleaning
Periodically clean the exterior of the pump with a damp cloth. Ensure the control panel and display remain free of chemical residue. Do not use abrasive cleaners.
6.2 Diaphragm Replacement
The diaphragm is a wear part and may need replacement over time, especially with aggressive chemicals or continuous operation. Refer to the pump's specific service manual for detailed instructions on diaphragm replacement. Always use genuine Etatron replacement parts.
6.3 Valve Maintenance
Check the suction and discharge valves regularly for blockages or wear. Clean or replace valves as necessary to ensure proper flow and prevent backflow.
6.4 Storage
If storing the pump for an extended period, drain all chemicals, flush the pump head with clean water, and store in a dry, cool place away from direct sunlight.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not dosing / No flow | Air in pump head; Suction line blocked; Valves clogged/worn; Chemical reservoir empty. | Re-prime the pump; Check and clear suction line; Clean/replace valves; Refill chemical reservoir. |
| Inaccurate dosing | Incorrect calibration; Air in system; Worn diaphragm. | Perform calibration; Check for air leaks; Inspect and replace diaphragm if necessary. |
| Leakage from pump head | Loose connections; Damaged diaphragm; Cracked pump head. | Tighten connections; Replace diaphragm; Contact service for pump head replacement. |
| Pump not powering on | No power supply; Blown fuse; Internal electrical fault. | Check power connection/outlet; Replace fuse (if accessible); Contact qualified technician. |
