5. Nastavení a instalace
Proper installation is critical for the pump's performance and longevity. Follow these steps carefully.
5.1 Kontroly před instalací
- Verify that the well casing má průměr alespoň 4 palce.
- Ensure the power supply matches the pump's requirements (230V/60HZ).
- Inspect the pump for any visible damage before installation.
5.2 drátové připojení
The pump comes with a 10-foot power cord. If an extension cord is needed, ensure it is rated for outdoor submersible use and properly sized for the pump's power requirements. Follow these steps for a waterproof electrical connection:
- Identify the Live, Neutral, and Ground wires from both the pump cable and the extension cord (if used).
- Securely cross-wind the copper wires of corresponding colors together.
- Apply electrical tape (included) tightly around each individual wire connection to insulate it.
- Wrap waterproof tape (included) over the electrical tape on each connection, ensuring a complete seal.
- Group the wrapped wires together and apply another layer of waterproof tape over the entire group.
- For final protection, wrap electrical tape over the waterproof-wrapped wire group.

Figure 5.2: Detailed Wire Connection Steps
5.3 Pipe Connection and Lowering the Pump
- Apply thread seal tape (Teflon tape) to the threads of the pump's outlet.
- Connect the discharge pipe to the pump's 1-1/4 inch FNPT outlet. Ensure a tight, leak-free connection.
- Install an external check valve in the discharge pipe, above the pump, to prevent water backflow.
- Attach a wire rope or nylon rope to the designated rope holes on the pump head. This rope will be used to lower and retrieve the pump. Do not use the power cable to lower or lift the pump.
- Carefully lower the pump into the well using the rope. Ensure the power cable is secured alongside the discharge pipe to prevent it from snagging or getting damaged.
- Observe the following depth requirements:
- The water outlet must be at least 16.4 feet below the dynamic water level.
- The maximum diving depth for the pump is 230 feet.
- Maintain a minimum distance of 9.8 feet between the bottom of the pump and the bottom of the well.

6. Návod k obsluze
Once installed, operating the WASSERMANN submersible pump is straightforward due to its built-in control box.
- Počáteční spuštění: After installation, ensure all connections are secure and the pump is fully submerged. Restore power to the pump. The pump should begin operating.
- Nepřetržitý provoz: The pump is designed for continuous operation as long as it remains submerged in clear, non-corrosive water.
- Sledování: Periodically check the water flow and pressure to ensure optimal performance. Any significant drop may indicate an issue.
- Vypnout: To stop the pump, disconnect its power supply.
Important Operating Considerations:
- Ensure the pump body is always under the water level when it is running.
- Do not run the pump dry, as this will cause severe damage.
- This pump is not designed for pumping water containing sand, silt, or other abrasive particles. Such materials will cause premature wear and failure.
