Height-adjustable float switch for automatic on/off control, 3. Universal hose connection for 25/32 mm hoses and G1 external thread, and 4. High-quality ceramic/rubber mechanical seal for durability.
3. Setup and Installation
- Unpacking: Carefully remove the pump from its packaging. Check for any signs of damage during transit. Retain the packaging for future storage or transport.
- Hose Connection: Attach a suitable hose (25mm or 32mm diameter) to the universal hose connection port. Secure the hose with a hose clamp (not included) to prevent leaks. The pump also supports a G1 (33.3 mm) external thread connection. For specific applications, a 90° angle G1½ (47.8 mm) adapter is included.
- Float Switch Adjustment: The float switch controls the automatic on/off function of the pump. Adjust the cable length of the float switch to set the desired water level for activation and deactivation. A shorter cable length results in a smaller operating range, while a longer cable length provides a wider range. Ensure the float switch can move freely.
- Placement: Place the pump on a stable, level surface in the water. Ensure the pump is fully submerged and positioned vertically. The maximum immersion depth is approximately 7 meters.
- Electrical Connection: Connect the pump to a properly grounded 230 Volt power outlet. The power cable is 10 meters long (H05RN-F type). Ensure the power supply matches the pump's specifications and that the outlet is protected by a residual current device (RCD).
4. Operating Instructions
The Einhell BG-SWP 7835 pump can operate in two modes: automatic mode via the float switch or continuous manual operation.
- Automatic Operation (Float Switch): When the float switch is set to allow free movement, the pump will automatically switch on when the water level rises to a certain point and switch off when the water level drops below a set minimum. Ensure the float switch is not obstructed.
- Continuous Operation: For continuous pumping, secure the float switch in an upward position (e.g., by attaching it to the pump's handle). The pump will then run continuously as long as it is connected to power and submerged. Monitor the water level to prevent dry running, which can damage the pump.
Important Operating Parameters:
- Maximum Delivery Height: Approximately 8 meters.
- Maximum Immersion Depth: Approximately 7 meters.
- Maximum Water Temperature: 35 °C. Do not pump liquids exceeding this temperature.
- Maximum Foreign Body Size: The pump can handle dirty water with suspended solids up to approximately 35 mm in diameter. Larger particles may cause blockages or damage.
5. Maintenance and Cleaning
Regular maintenance ensures the long life and reliable operation of your pump.
- Disconnect Power: Always disconnect the pump from the power supply before any cleaning or maintenance work.
- Cleaning the Pump: After use, especially when pumping very dirty water, rinse the pump thoroughly with clean water. This helps prevent sediment buildup in the pump housing and impeller.
- Checking the Impeller: Periodically check the impeller area for blockages from debris. If necessary, remove the base plate (refer to the technical diagram if available) and clean the impeller.
- Checking Seals: The pump features a high-quality ceramic/rubber mechanical seal. Inspect it periodically for wear or damage. If damage is observed, contact customer support for replacement.
- Storage: If the pump will not be used for an extended period, clean it thoroughly, drain all water, and store it in a dry, frost-free location.
6. Troubleshooting
Below are common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply Float switch not activated Motor overheating | Check power connection and fuse Adjust float switch position or operate manually Allow pump to cool down; check for blockages |
| Reduced pumping capacity | Hose kinked or blocked Impeller blocked Air in pump | Check and clear hose Clean impeller area Ensure pump is fully submerged and vent if necessary |
| Pump runs but no water is delivered | Water level too low Air lock Hose disconnected | Ensure pump is fully submerged Tilt pump slightly to release air Check hose connection |
