4. Setup
- Prepare the Battery: Ensure your Einhell Power X-Change 18V battery is fully charged. Open the lid of the flexible battery box and insert the charged battery, ensuring it clicks securely into place. Close the lid.
- Connect the Hose: Attach a suitable discharge hose to the hose connection on the top of the pump unit. Ensure the connection is tight to prevent leaks.
- Position the Pump: Place the pump unit into the water to be drained. The pump must be fully submerged for proper operation and cooling. The 5-meter connection cable allows for immersion depths of up to 4 meters.
- Position the Battery Box: Place the battery box in a dry, secure location, away from the water. The integrated cable holder can be used to manage excess cable, and the fastening hooks allow for suspension if desired.
- Check Operating Space: Ensure the pump has sufficient operating space, a minimum of 20 x 20 cm, as indicated in Figure 4.1.

Figure 4.1: This diagram illustrates the recommended minimum operating space for the pump, which is 20 x 20 cm, with a diameter of 131 mm for the pump itself. This ensures proper water intake and stable operation.
5. Operating Instructions
- Start the Pump: Once the pump is submerged and the hose is connected, locate the 3-stage switch on the battery box.
- Position 'I' for standard operation.
- Position 'II' for continuous operation (flat suction mode).
- Position 'O' to turn the pump off.
- Flat Suction: For draining water down to a residual level of 1 mm, select the 'II' position on the 3-stage switch. This activates the continuous operation function, allowing the pump to remove almost all water from the surface.
- Monitoring: Ensure the pump remains submerged during operation. Do not allow the pump to run dry, as this can cause damage.
- Stopping the Pump: To stop the pump, switch the 3-stage switch to the 'O' position.
- After Use: Remove the pump from the water and disconnect the battery from the battery box.
