4. Technical Specifications

5. Setup

5.1 Unpacking:

• Carefully remove the pump and all accessories from the packaging.
• Check for any damage during transit. Do not operate a damaged pump.
• Ensure all included components (wastewater pump, universal connection) are present.

5.2 Hose Connection:

• Connect a suitable discharge hose to the pump's universal connection. The pump features a 47.8 mm (1½ male thread) connection.
• Ensure the connection is secure and watertight to prevent leaks.

5.3 Placement and Immersion:

• Place the pump on a firm, level surface in the water to be pumped.
• Ensure the pump is fully immersed in the water. The maximum immersion depth is 7 meters.
• Use the carrying handle and hanging eyelet to safely lower the pump into deeper areas.

5.4 Power Connection:

• Connect the power plug to a properly grounded electrical outlet.
• Ensure the power cable is not kinked, stretched, or submerged in water during operation.

6. Operation

The Einhell GE-DP 7935 N-A ECO pump offers two operating modes: Aqua-Sensor mode and Continuous mode.

6.1 Aqua-Sensor Mode:

• The Aqua-Sensor technology automatically switches the pump on and off based on the water level.
• The sensor detects the water level and activates the pump when the water reaches a preset level, and deactivates it when the water drops below a certain level.
• Refer to the specific settings on your pump for adjusting the Aqua-Sensor activation and deactivation levels.

6.2 Continuous Mode:

• For continuous operation, the pump can be set to bypass the Aqua-Sensor.
• In this mode, the pump will run continuously as long as it is connected to power and immersed in water.
• Monitor the water level manually in continuous mode to prevent dry running, which can damage the pump.

6.3 Pumping Considerations:

• The pump can handle dirt particles up to 35 mm in diameter. Larger particles may cause blockages or damage.
• Ensure the discharge hose is clear and unobstructed to maintain optimal flow rate.
• Avoid pumping water with temperatures exceeding 35° Celsius.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump.

7.1 Cleaning the Pump:

• After each use, especially when pumping dirty water, rinse the pump thoroughly with clean water.
• Remove any debris or foreign objects that may have accumulated around the intake screen or impeller area.
• Always disconnect from power before cleaning.

7.2 Inspecting Components:

• Periodically check the power cable and plug for any signs of damage or wear.
• Inspect the hose connection for leaks or damage.
• Ensure the non-return valve is functioning correctly and not obstructed.
• The mechanical seal is designed for durability, but if you notice water leakage from the motor housing, contact customer support.

7.3 Winter Storage:

• If storing the pump for an extended period, especially in freezing temperatures, ensure all water is drained from the pump and hose.
• Store the pump in a dry, frost-free location.
