Key components include the maintenance-free capacitor motor, pressure vessel for quiet water supply, pressure switch for automatic activation of the domestic water station, tool-free water drain plug for frost protection, separate water filling opening for easy commissioning, high-quality mechanical seal system for long service life, and overload protection for the motor. The unit is designed for single-phase alternating current and suitable for garden irrigation with 1 or 2 sprinklers.

• Pressure Vessel: For energy-saving and quiet water supply.
• Pressure Switch: Automatically activates the pump based on water demand.
• Capacitor Motor: Maintenance-free operation.
• Overload Protection: Safeguards the motor from overheating.
• Water Filling Opening: Separate opening for easy initial filling.
• Drain Plug: Tool-free plug for draining water to prevent frost damage.
• High-Quality Sealing System: Ensures long product life.

4. Setup

Follow these steps for proper installation and initial setup:

1. Placement: Position the water station on a stable, level surface, protected from direct weather exposure and frost. Ensure adequate ventilation.
2. Connections:
   • Connect the suction hose to the pump's suction inlet. Ensure the hose is airtight to prevent air intake.
   • Connect the discharge hose to the pump's discharge outlet.
   • Install the included non-return valve on the suction side to prevent water backflow.
   • Use the provided thread sealing tape on all threaded connections to ensure a watertight seal.
3. Priming the Pump:
   • Open the separate water filling opening.
   • Fill the pump housing completely with clear water until it overflows.
   • Close the filling opening securely.
4. Electrical Connection: Connect the power cable to a suitable single-phase alternating current outlet (240 Volts). Ensure the circuit is protected by a residual current device (RCD).

5. Operating Instructions

Once set up, the Metabo HWW 3300/25 G operates largely automatically.

1. Starting the Pump:
   • Ensure the pump is primed (Section 4).
   • Plug in the power cable. The pump will start automatically when water is drawn (e.g., by opening a tap or activating a sprinkler).
   • The pressure switch will detect a drop in pressure and activate the pump to maintain water supply.
2. Applications:
   • Garden Irrigation: Connect 1 or 2 sprinklers to the discharge outlet. The pump will maintain pressure for efficient watering.
   • Groundwater Extraction: Use for drawing water from wells or cisterns for various uses.
   • Domestic Water Supply: Can be integrated into a household water system for non-potable uses, reducing reliance on municipal water.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your water station.

• Cleaning: Periodically clean the exterior of the pump with a damp cloth. Do not use harsh detergents or solvents.
• Frost Protection: Before the first frost, completely drain all water from the pump and hoses using the tool-free drain plug. Store the unit in a frost-free environment if possible.
• Check Connections: Regularly inspect all hose connections and fittings for leaks. Tighten as necessary.
• Motor: The capacitor motor is maintenance-free. No lubrication is required.
