Fusion Air Pumps

Quiet power ensures reliable aquarium aeration. Fusion air pumps feature a patented baffle system that fuse opposing forces. Enjoy quiet operation and the air output strength necessary to run airstones and air-driven ornaments and filters. Flexible, rubber feet absorb vibrations to further reduce noise. Use Fusion air pumps to promote proper gas exchange. Expel harmful gasses and introduce fresh, oxygen-rich air into your aquarium. Model 400 and up feature an integrated, adjustable dial for controlled air output.

Your new Fusion Air Pump should be installed in a dry and relatively dust-free location using the following recommended method.

Place the Fusion Air Pump on a surface at least 12 inches higher than the water level (i.e. a shelf). The shelf or surface should have a raised edge to prevent the air pump from sliding off. Never position the pump directly above the aquarium. Use a Check Valve, sold separately (#33949), in the air line between the aquarium and pump to prevent back siphoning.

Connecting fission air pumps to accessories:

• Attach one end one end of the air line tubing, sold separately (#33956), to the outlet(s) on the air pump.
• Attach the other end of the air line tubing to the filter(s), airstone(s), ornament(s), or any other air-driven aquarium accessories. Be sure that the air line tubing has no restrictions or kinks.
• Plug the Fusion Air Pump into outlet, making certain to allow for a "drip loop."

Using air control gang valves to distribute the air-flow to multiple aquariums or accessories:

• Install one more air control gang valves than required for your setup. This will be used to bleed off excess air from your system to prevent back pressure buildup on your air pump.
• To adjust airflow to different airstones, filters, or ornaments, start by fully opening all valves, including the bleed-off valve. Then plug in your pump and slowly close the bleed-off valve until all air accessories are working. For fine-tuning, slowly close any valve that controls an accessory that is bubbling excessively. Depending on the output of your particular air pump, the bleed-off valve may have to be closed completely. It does not matter which air control valve in your setup is used as a bleed-off valve.

Back Pressure
Back pressure is the buildup of pressure on the air pump's diaphragm caused by clogged airstones, kinked airlines, or valve settings that are too restrictive. If your pump produces more air than needed to run your accessories, always use the bleed-off valve to relieve the pressure. Periodically inspect the air lines and clean or replace clogged airstones. Constant excessive back pressure on the pump may cause premature diaphragm failure and require early replacement of the diaphragm.

Removing the Pump
When you want to shut off and remove the air pump from the aquarium, always take off the air line before unplugging the pump and tape the end to the frame of the aquarium.

Troubleshooting Tips
If you notice a significant decrease or a total interruption in output:

• Make sure the air pump is plugged in and all parts are properly connected.
• Make sure the air hoses are free from blockages and restrictions, and check the pressure and air on all air valves.
• If the air-driven accessories in the aquarium are not outputting air, remove the air line from the pump to ensure that air is being produced.
• If the air pump is not outputting air, the likely cause is a torn or other wise weakened diaphragm. Inspect the diaphragm for rips, holes, or tears. Replace diaphragm if necessary. Note: Always check and or replace diaphragm first before replacing any other parts. The diaphragm is the most common cause of reduced or interrupted air output.

Maintenance

External Maintenance
To keep the outside of your pump clean and dust-free, wipe with a soft, damp cloth and a mild cleanser. Never spray or immerse your pump. You will never need to oil or clean any internal components of your pump.

Airstone, Ornament, and Airline Maintenance
Periodically check and clean your aquarium's air system for optimal performance as follows:

• Carefully inspect all air lines. Adjust air line so that it is not pinched or kinked. Replace any items that are damaged.
• All filters, airstones, and other air driven accessories should be cleaned according to the manufacture's instructions. Regular removal of algae and other buildup from air lines and moving parts will help maintain optimal performance of your overall aquarium system.
• To optimize airstone performance, clean off algae and other buildup, at least once a month.
