Note: If the first valve on the air control assembly is fully opened, air volume to the remaining outlets will
be reduced.
To alleviate excess air pressure or overproduction of air, it is recommended to open the last valve every 2
weeks or when required. In doing this, you will increase the life of the pump and diaphragms by preventing
premature wear.
BACK PRESSURE
Back pressure is the build-up of pressure on the diaphragm due to restricted air flow. This occurs when
excess air is produced by the air pump, or when the air channels are inadvertently blocked. Back pressure
over time resulting from clogged air stones or other air system blockages and restrictions will cause the
diaphragm to expand or rupture. An expanded diaphragm leads to a loss of air volume while a rupture
results in the total loss of air.
MAINTENANCE (EXTERNAL APPEARANCE)
Remove dust and grime with a soft, damp cloth. Do not immerse pump in water. Do not use detergents.
AIR STONE, AIRLINE, AND ORNAMENT MAINTENANCE
This pump requires no regular internal maintenance during its life.
The rest of the air system should be periodically checked and cleaned.
• Airlines should be carefully inspected whenever standard aquarium maintenance is performed. Adjust,
or if required, replace all sections which are pinched, kinked, or otherwise damaged.
• All attached air-driven aquarium ornaments should be regularly maintained. Algae growths should be
removed from moving parts and kept as clean as possible. Internal air tubes should be cleaned.
• Air stones should be kept clean and free of debris or algae build-up. The ideal situation is to replace them
every month, alternating with an extra set which has been dried over that period and cleaned before
being placed in the aquarium.
Two complete sets of air stones alternately changed each month will extend the life of the air stones and
help keep back pressure to a minimum. Clogged air stones and air-driven aquarium ornaments will lead to
low air pressure output and also reduce the life of the diaphragms.
TROUBLE SHOOTING TIPS
If the air pump fails to produce air, check the following:
1. Ensure that the air pump is plugged in.
2. Ensure that there are no blockages in the air hose assembly and that all valves allow air passage. If no
air is produced by the accessories in the aquarium, remove the air line from the pump and ensure that
air is being produced.
3. If the air pump produces no output, the most common problem encountered with any air pump is a ripped
or weakened diaphragm. Remove airline. Unplug appliance. Inspect the diaphragm for tears or rips. Any
opening in the diaphragm will make it impossible for the pump to produce air for aeration purposes.
Always inspect the diaphragm first before replacing other parts in the pump.
REMOVING THE PUMP
Important: Whenever the air pump must be shut off and removed from the aeration system, always take
off the airline before the pump is unplugged. This will prevent water from siphoning back into the pump. If
the airline cannot be removed before unplugging the power cord, raise the pump above the water level.
REPLACEMENT PARTS
Repair kits for all wearable parts are available for all Fluval Air Pumps. These can be easily obtained at
your local aquarium and pet supply store. Failure of the electric coil or any other electrical part requires
proper service, and should be returned to the manufacturer for repairs or replacement (see warranty for
full details).
