4. Setup Instructions
4.1. Choosing Installation Method
The hygger HG268 pump can be used in two primary configurations: submersible or inline (external).
Submersible Use:
For submersible use, the pump is placed directly into the water. You can choose between side suction or bottom suction inlet covers depending on your water level requirements.
- Side Suction: Attach the side suction cover to the pump. This is suitable for standard water levels.
- Bottom Suction: Attach the bottom suction cover for operation in lower water levels.
Inline (External) Use:
For inline use, the pump is placed outside the water, and water is fed to it via an inlet pipe. Ensure the pump is filled with water before starting operation to prevent dry running.
- Remove the protective inlet cover.
- Connect rigid or soft pipes to both the inlet and outlet ports.
- Ensure the pump is primed (filled with water) before connecting power.

4.2. Attaching Nozzles
The pump comes with three different sized nozzles (0.75", 0.98", 1.25") to accommodate various hose diameters and flow requirements.
- Select the appropriate nozzle size for your hose.
- Screw the chosen nozzle onto the pump's outlet port until secure.

4.3. Securing the Pump
The pump is equipped with four strong suction cups on its base for secure placement. Ensure the surface is clean and smooth before pressing the pump firmly into place.
5. Operating Instructions
5.1. Connecting the Controller
Connect the pump unit to the external controller, and then connect the controller to a standard AC 110-120V / 60Hz power outlet. The LCD display on the controller will illuminate.

5.2. Power On/Off
Press the "Switch" button on the controller to turn the pump on or off.
5.3. Adjusting Flow Rate
The pump offers 10 adjustable flow rate levels. Use the "+" and "-" buttons on the controller to increase or decrease the water flow speed. The current level will be displayed on the LCD screen.

5.4. Operation Modes
The controller features three distinct operation modes: Constant Flow, Wave Mode, and Feeding Mode.
- Press the "M" (Mode Switching) button to cycle through the available modes.
- Constant Flow Mode: Provides a continuous, steady water flow at the set speed.
- Wave Mode: Creates a pulsating flow to simulate natural wave action. Use the "+" and "-" buttons to adjust the wave bands.
- Feeding Mode: Pauses pump operation for 10 minutes to allow for feeding without disturbing food or fish. The pump will automatically restart after 10 minutes.

6.1. Cleaning the Pump
The pump features a detachable design for easy cleaning without tools.
- Disconnect the pump from the power source before any cleaning or maintenance.
- Remove the front cover and impeller cover.
- Carefully remove the impeller/rotor assembly.
- Clean all components, including the impeller, impeller housing, and inlet covers, with a soft brush and clean water to remove any debris, algae, or mineral buildup.
- Inspect the ceramic shaft for wear or damage.
- Reassemble all parts securely.

| Anti-dry protection activated | Ensure pump is fully submerged or primed for inline use. Check for blockages. | |
| Low flow rate | Inlet/outlet clogged | Clean inlet covers, impeller, and hoses. |
| Flow rate set too low | Increase flow rate using the "+" button on the controller. | |
| Air in pump (inline use) | Ensure pump is fully primed with water before starting. | |
| Excessive noise/vibration | Debris in impeller | Clean impeller and housing. |
| Pump not securely placed | Ensure suction cups are firmly attached to a clean, smooth surface. | |
