4. Setup
Follow these steps to set up your air pump:
- Prepare Air Stones: Soak the air stones in water for at least 30 minutes before use to ensure optimal bubble diffusion.
- Connect Main Hose: Attach one end of the main hose to the air outlet on the pump.
- Install Check Valve: If the air pump will be placed below the water level of your tank or pond, install the check valve in the main hose to prevent water backflow into the pump. Ensure the check valve is oriented correctly (air flows towards the tank).
- Connect Diverter Valve (18W model): Attach the diverter valve to the main hose (after the check valve, if used). This allows you to distribute air to multiple thin hoses.
- Connect Thin Hoses and Air Stones: Connect the thin hoses to the outlets of the diverter valve. Attach an air stone to the end of each thin hose.
- Position in Water: Place the air stones in your aquarium or pond. Ensure the pump unit is placed in a stable location.

5. Operating Instructions
Operating your hygger air pump is straightforward:
- Power On: Press the 'Power On/Off' button to turn on the pump. The display will illuminate, showing the current battery status and airflow level.
