INSTALLATION AND USE
EN-7
9. Insert the AquaStop valve into the intake and output connectors on the cover, and
push down on the locking lever to lock it in place.
10. Open the AquaStop valve by pushing the valve lever all the way down. (The valve
must be fully open before the unit is turned on or primed.)
6. Start the filter
1. Check your installation.
Be sure lift-lock clamps are securely closed.
Make certain that the AquaStop valve is
fully open and pushed all the way down.
Check that the intake assembly is fully submerged in water.
2. Pump the instant-prime handle by pulling it
up and pushing it down 3 to 4 times until you
hear water being drawn into the unit. Return
the instant-prime handle to the down position.
As water flows through the intake hosing, it
will fill the canister, pushing air out of its way.
Air will be expelled through the output nozzle,
which should be located slightly above the
water surface. To expel all the air in the system
as quickly as possible, the AquaStop valve must
be fully open. Be sure the lever is all the way down.
3. Once the bubbling in the tank stops, you’ll know the air is out of the system, and the
canister is full; plug the power cord into an electrical outlet.
THE PUMP WILL START IMMEDIATELY. Water should flow from the output nozzle continuously. If it does not, check your
installation to be sure of the following:
IMPORTANT: To prevent damage, never plug the filter in unless the canister is completely full of water.
Adjusting Water Flow
Once the filter is operating continuously, you can use the top lever on the AquaStop to regulate the water flow.
To reduce the water flow, lift the lever up to halfway, but no higher. This can be done once the unit is fully operational,
and will not harm the motor. However, never run the filter with the lever up (closed) more than half way.
Air in the Filter
Some air will become trapped in the canister as it fills; air may also be released by new media.
Eventually, the filter will expel all air pockets. If you notice excessive bursts of bubbling over an extended period of time, check all hosing
and connections for air leaks. Also, make sure there is no air source (such as an airstone or aeration device) near the intake strainer.

• No kinks or loops in the hosing.
• The base of the canister is not more than 4.5 ft. (1.4 m) below the water level.
• The water is not more than 7 in. (17.5 cm) below the aquarium rim.
• The intake assembly is securely attached to the aquarium wall.
• No air is bubbling into the water at points where the intake assembly and the output nozzle connect to the hosing.
• No water is escaping from the hosing at the AquaStop valve connection points.
• The canister cover is securely closed.
• The AquaStop valve must be fully open before the unit is turned on or primed.
