4. Setup
4.1 Unpacking
Carefully remove the pump and all accessories from the packaging. Inspect for any damage that may have occurred during transit. Retain packaging for future storage or transport.
4.2 Connecting the Discharge Hose
The pump comes with a multi-size adapter for versatile hose connections. Choose the appropriate adapter size for your discharge hose (33mm, G1", G1-1/4", or 26mm). Securely attach the hose to the pump's outlet. Ensure all connections are tight to prevent leaks.

4.3 Positioning the Pump
Place the pump on a stable, flat surface in the water. Ensure the pump is fully submerged and not resting on any debris that could block the intake. The maximum immersion depth is 7 meters.
4.4 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 minimum and maximum water levels for operation. A shorter cable length will result in a smaller operating range (e.g., 3 cm to 17.5 cm water level difference for activation/deactivation).
5. Operation
5.1 Automatic Mode (Float Switch)
In automatic mode, the pump will start and stop based on the water level, as determined by the float switch position. When the water level rises and lifts the float switch, the pump will activate. When the water level drops and the float switch lowers, the pump will deactivate. This ensures autonomous operation without constant supervision.
Image 4: Visual representation of the pump's automatic and manual operation modes. It shows the pump working ('Arbeitend' - Working) when the float switch is raised by water and stopping ('Stopp' - Stop) when the float switch is lowered. It also indicates that if the float switch is blocked, the pump will continue to operate without automatic shut-off. The operating range for automatic start/stop is shown as 3 cm to 17.5 cm water level difference.
5.2 Manual Mode
To operate the pump continuously, you can secure the float switch in an upright position. In this mode, the pump will run constantly, allowing for drainage down to a minimum water level of approximately 7mm. Be sure to monitor the pump in manual mode to prevent dry running, which can damage the motor.
5.3 Powering On/Off
Once the pump is correctly positioned and the hose is connected, plug the power cord into a suitable electrical outlet. The pump will begin operation according to the float switch setting (automatic mode) or immediately if the float switch is secured (manual mode). To turn off, simply unplug the pump from the power source.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your FOTING submersible pump.
- Cleaning: Periodically clean the pump's intake screen to remove any debris, leaves, or small particles that may accumulate and restrict water flow. Disconnect power before cleaning.
- Inspection: Regularly inspect the power cord and plug for any signs of damage. Check hose connections for wear or leaks.
- Winter Storage: If storing the pump for an extended period or during freezing temperatures, drain all water from the pump and hose. Clean the pump thoroughly and store it in a dry, frost-free location.
- Float Switch: Ensure the float switch moves freely and is not obstructed by debris.
7. Troubleshooting
Before contacting customer support, please refer to the following troubleshooting guide for common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply Float switch not activated Thermal overload activated | Check power connection and outlet Adjust float switch position or secure for manual mode Allow pump to cool down; check for blockages |
| Low flow rate or no water discharge | Clogged intake screen or hose Air lock in pump Hose kinked or too long/small diameter | Clean intake screen and check hose for blockages Tilt pump to release trapped air Ensure hose is clear, unkinked, and appropriate size |
| Pump runs continuously in automatic mode | Float switch stuck in 'on' position Water level not dropping sufficiently | Check float switch for obstructions and ensure free movement Verify water source is not continuously replenishing |
| Pump makes unusual noise | Debris in impeller Dry running | Disconnect power and inspect impeller for foreign objects Ensure pump is fully submerged; avoid dry running |
