Setup

Follow these steps to set up your hygger 18W Rechargeable Aquarium Air Pump:

1. Connect Main Hose: Attach one end of the main hose to the copper metal outlet on the air pump.
2. Insert Check Valve: Cut the main hose and insert the check valve. Ensure the arrow on the check valve points towards the diverter/aquarium to prevent water backflow into the pump.
3. Connect Diverter: Attach the other end of the main hose (with the check valve) to the inlet of the 4-hole diverter.
4. Connect Air Hoses: Connect each of the four 6.5ft air hoses to the outlets of the diverter.
5. Connect Air Stones: Attach an air stone to the end of each air hose. Place the air stones in your aquarium or pond.
6. Power Connection: Plug the power adapter into the pump and then into a wall outlet for daily use and charging.

Important Note on Check Valve Placement:

• If the air pump is placed below the water level of the aquarium, a check valve is essential to prevent water from siphoning back into the pump during a power outage, which can cause damage.
• If the air pump is placed above the water level, a check valve is not strictly necessary but is still recommended for added safety.

• ON/OFF Button: Press and hold for 3 seconds to turn the pump on or off.
• +/- Buttons: Adjust the overall airflow volume from level 1 to 9.
• Battery Display: Shows the current battery charge level.
• DC/AC Indicator: Indicates whether the pump is running on DC (battery) or AC (plugged in) power.

Adjusting Airflow

There are two ways to adjust the airflow:

1. Overall Airflow: Use the "+/-" buttons on the control panel to adjust the total air output from level 1 (minimum) to level 9 (maximum).
2. Individual Output Airflow: The 4-hole diverter allows you to fine-tune or completely close the airflow to each individual air stone. Rotate the valves on the diverter to adjust the flow from OFF to 100%.

Dual-Power Mode (AC/DC)

The hygger air pump operates in a dual-power mode for continuous aeration:

• AC Power (Plugged In): When connected to the power adapter and a wall outlet, the pump runs on AC power and simultaneously recharges its internal lithium battery.
• DC Power (Battery Backup): In the event of a power failure, the pump automatically switches to DC power, utilizing its built-in large-capacity lithium battery to ensure uninterrupted operation.

The built-in battery charges fully in approximately 3 hours. It can provide up to 8 hours of operation at maximum airflow or up to 100 hours at minimum airflow, making it a reliable backup for emergencies.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your air pump:

• Battery Health: To maintain battery health, regularly (every 2 months is recommended) unplug the pump and allow it to run on battery power until it fully discharges. Then, recharge it completely. This helps to calibrate the battery and prolong its lifespan.
• Air Stone Cleaning: Over time, air stones can become clogged, reducing airflow. Clean or replace air stones as needed to ensure efficient bubble production.
• Hose Inspection: Periodically check air hoses for kinks, cracks, or blockages. Replace any damaged hoses to maintain proper airflow.
• Pump Exterior: Wipe the exterior of the pump with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the pump is dry before reconnecting power.
