1. Introduction
The AL-KO HW 6000 FMS Premium Domestic Water Pump is a high-performance system designed for reliable water supply and pressure boosting. It is ideal for drawing rainwater from wells, cisterns, and rainwater tanks, and for enhancing water pressure in domestic, yard, and garden applications. This manual provides essential information for safe installation, operation, and maintenance of your pump.
2. Safety Information
Always observe the following safety precautions to prevent personal injury and damage to the equipment:
- Electrical Safety: Ensure the power supply matches the pump's specifications (230V). Always disconnect power before performing any maintenance or installation. Use a ground fault circuit interrupter (GFCI) for outdoor use.
- Water Safety: Do not pump flammable or corrosive liquids. Ensure all connections are watertight to prevent leaks and electrical hazards.
- Installation: The pump must be installed in a location protected from rain and splashes. Ensure stable placement on a level surface.
- Operation: Never operate the pump dry. The integrated dry-run protection helps, but manual checks are crucial during initial setup.
- Children and Pets: Keep children and pets away from the operating pump.
- Maintenance: Only perform maintenance tasks described in this manual. For complex repairs, contact qualified service personnel.
3. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your AL-KO HW 6000 FMS Premium pump.
3.1 Unpacking and Inspection
Carefully remove the pump from its packaging. Inspect for any signs of damage during transit. Ensure all components listed in the packing contents are present, including the instruction manual, corner connection, and filter wrench.
3.2 Placement
Place the pump on a firm, level surface. It must be protected from direct weather exposure (rain, splashes). Ensure adequate ventilation around the unit.

3.3 Connecting Water Lines
- Suction Line: Connect a robust, non-kinking suction hose to the pump's suction inlet. Ensure the suction line is completely airtight to prevent air ingress, which can impair pump performance. For optimal self-priming, the suction height should not exceed 8 meters.
- Pressure Line: Connect the pressure line to the pump's outlet. The included corner connection and check valve should be used to prevent backflow and maintain pressure.
- Priming the Pump: Before initial operation, fill the pump housing completely with water through the designated filling opening until no more air bubbles emerge. This is essential for self-priming.
3.4 Electrical Connection
Connect the pump to a properly grounded 230V power outlet. Ensure the electrical circuit is protected by a residual current device (RCD/GFCI) for safety, especially in damp environments or outdoor installations.
4. Operation
The AL-KO HW 6000 FMS Premium pump features intelligent electronic control for efficient and safe operation.
4.1 Starting the Pump
- Ensure the pump is properly primed (see Section 3.3).
- Connect the pump to the power supply. The pump will perform a self-check.
- The Flow-Measurement System (FMS) display will show the current operating status.
- Open a water tap in your system. The pump will automatically start to deliver water.

4.2 Eco Mode
To save energy, switch the pump to Eco mode. This mode can reduce energy consumption by approximately 15% compared to normal operation. Refer to the pump's display and controls for activating Eco mode.
4.3 Dry-Run Protection
The integrated dry-run protection system automatically shuts off the pump if no water is detected in the suction line, preventing damage. If the pump stops due to dry-run protection, check your water source and suction line for issues before restarting.
5. Maintenance
Regular maintenance ensures the long-term performance and reliability of your pump.
5.1 Cleaning the Pre-Filter
The pump is equipped with a large, easy-to-clean pre-filter that protects the pump's interior from dirt and debris. Regularly check and clean the filter, especially if you notice a decrease in pump performance.
- Disconnect the pump from the power supply.
- Close any valves on the suction and pressure lines.
- Use the provided filter wrench to carefully open the filter housing.
- Remove the filter element and rinse it thoroughly under clean running water.
- Inspect the filter element for damage and replace if necessary.
- Reinsert the clean filter element and securely close the filter housing using the wrench.
- Reconnect power and prime the pump if necessary before restarting.

5.2 Winterization
If the pump is exposed to freezing temperatures, it must be drained completely to prevent frost damage. Disconnect all water lines and open the drain plug to allow all water to escape. Store the pump in a frost-free location.
6. Troubleshooting
This section provides solutions to common issues you might encounter with your AL-KO HW 6000 FMS Premium pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start or deliver water. | No power supply; pump not primed; air in suction line; dry-run protection activated; clogged filter. | Check power connection; prime the pump; check suction line for leaks; check water source; clean pre-filter. |
| Reduced water flow or pressure. | Clogged pre-filter; air in suction line; low water level in source; partially closed valves. | Clean pre-filter; check suction line for leaks; ensure adequate water supply; open all valves fully. |
| Pump runs continuously or cycles frequently. | Leak in pressure system; check valve faulty; insufficient air in pressure tank. | Inspect all connections for leaks; check/replace check valve; ensure proper air charge in the pressure tank (refer to specific instructions for pressure tank maintenance). |
| Unusual noise during operation. | Air in pump/lines; foreign object in pump; motor bearing issue. | Bleed air from the system; disconnect power and inspect pump impeller for obstructions (if safe to do so); if noise persists, contact service. |
If you are unable to resolve the issue using the troubleshooting guide, please contact AL-KO customer support or a qualified service technician.
