FLUVAL FILTER INSTALLATION
1. Unpack and identify all parts. This filter is only for installation with Fluval Aquarium sets with
undertank connections.
2. Prepare intake/output connections.
Remove the Aquastop valve (3) from canister cover (5) by first lifting the black lever all the way up and then fully
lifting the silver lever.
The black lever closes and opens the Aquastop valves. When the black lever is fully up, the valves are fully closed
and do not allow water to flow between the filter and aquarium tank. When the black lever is fully down, the valves are
fully open and allow maximum water flow between filter and aquarium tank
The silver lever locks the Aquastop valve to the canister cover (5). When the silver lever is fully up, the Aquastop
valve is disengaged from the canister cover (5). Important: to avoid water spill, the silver lever
cannot be operated if the black lever is not fully up.
Connect the ribbed hoses (2) to the Aquastop valve (3).
Attach the first hose to the IN and the second hose to the OUT connector of the
Aquastop valve in the following way:
a. Push one end of the hosing onto the valve; push it all the way, as far as it will go.
b. Turn the lock nut counter clockwise until it is as tight as you can make it without forcing.
Connect the ribbed hoses to the Aquarium's intake/output stems that you installed in
Section #1.
Open the cabinet. Connect the loose end of the ribbed hose (2) that is attached to the IN connector of the Aquastop
valve (3) to the connector stem that is attached to the aquarium intake and then connect the loose end of the ribbed
hose (2) that is attached to the OUT connector of the Aquastop valve (3) to the connector stem that is attached to the
aquarium output, in the following way:
a. Loosen the metal clamp (1) and slide it onto the loose end of the hosing (2).
b. Push the end of the hosing onto the aquarium connector stem; push it all the way, as far as it will go.
c. Position the metal clamp over the rubber connector and tighten with a screwdriver.
WARNING! – Avoid forcing the ribbed hoses sideways near the Aquastop and Connector Stem connections at
all times to prevent the ribbed hosing from slipping out of these connections and consequently emptying the
aquarium.
3. Prepare the Filter
IMPORTANT: The Carbon and BIOMAX media supplied with your Fluval filter have been deliberately placed in the
Upper, Mid, and Lower level baskets to indicate their recommended placement for optimal basic filtration. Be sure
to note this positioning and place the media in baskets at the same levels as you prepare the filter
for use.

1. Remove the foam screen frame, media cover, and media baskets from the filter canister.
As you remove Carbon and BIOMAX from the baskets, note which levels they were packed in. Then
remove their outer wrappers; do not remove carbon from porous bag(s).
2. Rinse baskets and media materials under running tap water to remove any dust and place
media in baskets. Or, if you prefer, select other media of your own choosing. Please refer to
instruction manual included within the filter box for more information.
3. Place the rinsed and filled media baskets back in the canister and put the media cover back
on the top basket. IMPORTANT: Make sure that each media is positioned at the same level it was
packaged in, unless you are deliberately choosing a different filtration plan than the recommended
basic setup. Never overfill baskets. If the cover or baskets are out of position, the cover (5)
may not close properly.
4. Rinse both sides of the foam screen frame under tap water before initial use to remove any possible contaminants
and slide it back into position in the canister, with the flat end down. If the screen does not seem to fit properly, be
sure it is not upside down.
