2. Important Safety Warnings
Please read and follow all safety instructions carefully to prevent injury or damage to the product and your aquarium setup.
- Electrical Safety: Always ensure your hands are dry before handling the power cord or plug. Do not operate the pump if the cord is damaged.
- Water Contact: Never place the air pump directly into water. The pump must always be positioned above the water level of your aquarium.
- Drip Loop: To prevent water from traveling down the power cord and into the electrical outlet, always create a "drip loop" with the power cord.
- Check Valve: For added safety, install a check valve (sold separately) in the airline tubing. This prevents water from siphoning back into the air pump during a power outage.
- Ventilation: Ensure the air pump is placed in a well-ventilated area to prevent overheating. Do not cover the pump.
- Children and Pets: Keep the air pump and its components out of reach of children and pets.
- Proposition 65 Warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

5. Setup Instructions
Follow these steps to properly set up your Penn-Plax Air-Pod Aquarium Air Pump:
- Placement: Position the air pump on a flat, stable surface. It is crucial that the air pump is placed above the water level of your aquarium. If this is not possible, install a check valve (sold separately) in the airline tubing to prevent water backflow.
- Connect Airline Tubing: Cut a suitable length of standard airline tubing (3/16 inch, not included) for each air outlet. Connect one end of the tubing to an air outlet on the pump and the other end to an air stone or other air-driven aquarium accessory (not included) placed inside your aquarium.
- Install Check Valve (Recommended): If the pump is placed below the water level, cut the airline tubing and insert a check valve (sold separately) between the pump and the aquarium. Ensure the check valve is oriented correctly to allow air flow towards the aquarium.
- Create Drip Loop: Arrange the power cord so that it hangs below the electrical outlet, forming a "drip loop." This prevents water from running down the cord and into the outlet.
- Power Connection: Plug the air pump into a grounded electrical outlet.
6. Operating Instructions
Once the pump is set up, operating it is straightforward:
- Power On: After plugging in the pump, it will begin to operate immediately, producing air flow through the connected tubing and accessories.
- Adjust Air Flow: Use the adjustable air power control knobs located on the pump to increase or decrease the air flow from each outlet. Turn the knob clockwise to increase flow and counter-clockwise to decrease flow.
- Monitoring: Observe the air bubbles in your aquarium to ensure adequate aeration. Adjust the flow as needed for your specific aquarium requirements.
- Power Off: To turn off the pump, simply unplug it from the electrical outlet.
7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your air pump:
- Exterior Cleaning: Periodically wipe the exterior of the pump with a dry or slightly damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no water enters the pump.
- Airline Tubing and Air Stones: Regularly check airline tubing for kinks, blockages, or deterioration. Clean or replace air stones if they become clogged, as this can reduce air flow and strain the pump.
- Internal Components: The internal diaphragm and motor are designed for long-term use. If air output significantly decreases over time, it may indicate wear on the diaphragm. Replacement parts may be available from Penn-Plax customer service.
- Ventilation: Ensure the pump's ventilation openings remain clear of dust and debris.
