Product Features
Intelligent LED Controller
The pump is equipped with an LED intelligent controller offering various modes and settings:
- Pumping Mode: 20 adjustable gears (L-01 to L-20) for varying flow rates.
- Wave-making Mode: 20 adjustable gears (F-01 to F-20) for wave frequency.
- Feeding Mode: Press the feeding button to pause the pump for 10 minutes, allowing fish to feed undisturbed.
- Lock Screen Function: Long press for 3 seconds to lock or unlock the screen, preventing accidental changes.

Setup Instructions
The hygger water pump can be used in both submersible and inline configurations. Ensure all connections are secure before operation.
Installation Steps
- Connect the water outlet connector(s) to the pump's outlet. Three different sizes (16/19/25mm) are provided to match your tubing.
- Connect the pump to the intelligent controller. Ensure the arrow connections are aligned and secured.
- Connect the charger/power adapter to the controller.
- Important: Before plugging the power adapter into an electrical outlet, ensure the pump is fully submerged in water. This prevents air from entering the lines, which can cause operational issues.

Usage Modes
The pump supports two primary water intake modes:
- Bottom Suction Mode: Ideal for pumping water at low levels, effectively removing food residues, feces, and other impurities from the bottom of the tank.
- Side Mode: Provides a larger pumping area, suitable for sucking away floating pollutants in the fish tank.

Operating Instructions
Use the intelligent controller to manage the pump's functions:
- Power On/Off: Short press the power button to switch the pump on or off.
- Adjust Flow/Wave: Use the '+' and '-' buttons to increase or decrease the gear level for either pumping (L-mode) or wave-making (F-mode).
- Switch Modes: Press the wave icon button to toggle between pumping mode and wave-making mode.
- Feeding Mode: Press the fish icon button to activate feeding mode, pausing the pump for 10 minutes.
- Lock/Unlock Screen: Long press the power button for 3 seconds to lock or unlock the controller screen.

Maintenance
Regular maintenance ensures optimal performance and longevity of your pump.
- Cleaning: The pump's detachable design allows for easy disassembly and cleaning. Regularly clean the impeller and pump housing to prevent blockages and maintain efficient water flow.
- Shaft Inspection: Periodically inspect the ceramic shaft for wear and tear. The wear-resistant ceramic shaft is designed for durability, but replacement may be necessary over time.
Troubleshooting
The intelligent control system includes protection features that display error codes on the controller if an issue occurs:
- E1: Overvoltage Protection - Input voltage of the pump is ≥ 28V. Check power supply.
- E2: Undervoltage Protection - Input voltage of the pump is < 18V. Check power supply.
- E3: Overcurrent Protection - The current is higher than normal. Check for blockages or motor issues.
- E4: Dry Running Protection - The pump is not submerged in water. Ensure the pump is fully immersed.
- E5: Motor Blockade Protection - The pump motor is stuck. Clean the impeller and check for obstructions.
