ADJUSTING THE WATER FLOW
The water output can be custom selected based on the desired flow. By simply rotating the
adjustable 3-way flow control knob you can select one of 3 output settings as well as
adjust the flow rate.
(A) Top output, for maximum circulation and oxygenation.
(B) The integrated spray bar, to provide even gentle flow for planted aquariums.
(C) Bottom output for deep water agitation and maximum circulation.
MAINTAINING THE U2, U3 and U4 FILTERS
WARNING: ALWAYS DISCONNECT APPLIANCES IN THE AQUARIUM FROM THE ELECTRICAL
SUPPLY BEFORE PLACING HANDS IN THE WATER, BEFORE PUTTING ON OR TAKING OFF PARTS,
AND WHENEVER THE FILTER EQUIPMENT IS BEING INSTALLED, MAINTAINED OR HANDLED.
Following a routine maintenance schedule will result in a healthier aquarium and extend
the life of the filter. Fluval filters have been designed to facilitate these tasks as they can
be done within a matter of minutes. For best results please follow our maintenance
schedule recommendations.
FILTER CARTRIDGE REPLACEMENT
Replace 1 Poly/Carbon cartridge every 2 weeks. Replace Alternate Foam Pads every
3-6 months. Replace ½ quantity of BIOMAX nodes every 5-6 months
FILTER MAINTENANCE
Clean Impeller and Impeller well every 4 months. Replace impeller yearly for optimal
performance and to prevent wearing. Clean filter body 1 time per year.
HOW TO REPLACE THE FILTER CARTRIDGES
IMPORTANT: Do not replace all filtration cartridges at the same time. Alternate filter
cartridge changes so that some older cartridges remain in use. This ensures the re-seeding of
beneficial bacteria, so that colonies discarded with older cartridges will be replaced by
vigorous new ones. To enhance bacterial action, pour a dose of Nutrafin Cycle Biological
Aquarium Supplement onto your filter cartridges each time you change the media.
1. Unplug the power cord.
2. Open the filter cover (To make the operation easier
and in case the filter is positioned under an aquarium
frame, tilt the filter forward until it stops but make en
sure there is enough electrical cord to allow the filter
to pull forward). (ill. R-S).
3. Slide the Foam cartridge frames out of the filter body
keeping them vertical to avoid releasing the debris
collected inside the debris receptacle. Place them in an
empty bucket. (ill. T).
4. Remove the Poly/carbon cartridge from the cartridge
frame. (ill. U).
5. Remove the foam. Rinse the debris receptacle and the
foam pads using water taken from the aquarium or
replace one of the foams following the recommended
replacement schedule. Do not use tap water as this
will kill the beneficial bacteria in your foam.
NEVER use soap or detergents as these products could be
harmful to the inhabitants of your aquarium.
6. Replace the foam pad. Make sure the foam is positioned
behind the tabs on the sides of the frame.
7. With the carbon side facing out re-insert the Poly/
Carbon cartridge by inserting the lower end of the
cartridge into the lower end of the cartridge frame then
snapping the top side of the cartridge under the two
tabs on the top side of the frame. Do not press too hard
as the cartridge must sit on the top of the tabs on the
sides of the frame.
Hint: For best results replace 1 poly/Carbon cartridge
every 2 weeks.
8. Slide the BIOMAX cartridge out and place it in the sink
or bucket.
9. Pull open the tab on the side of the cartridge, opening
the cover. Rinse the BIOMAX with aquarium water, never tap water, or replace ½ the
quantity every 5-6 months. Never replace all the
BIOMAX nodes at one time, as valuable
colonies of beneficial bacteria would be lost.
(ill. V).
10. After rinsing, put the BIOMAX back in cartridge
and close the cover. For best results completely fill
the cartridge with BIOMAX nodes but allow the
cover to close easily.
11. Re-insert foam cartridge frames into the filter with
the poly/carbon pad facing inwards. Re-insert the BIOMAX cartridge into the filter
making sure to properly align the hole at the bottom of the cartridge directly on the
top of the impeller opening. Close the filter cover and if required snap the filter body
back into position on the filter bracket.
HOW TO CARE FOR THE IMPELLER AND MOTOR
The impeller well has an effective self-cleaning feature. However, it is recommended that
you remove the motor and inspect the impeller as part of your routine maintenance.
Keeping the impeller clean lengthens its life and the life of the motor.
(W)
1. Unplug the power cord.
2. Release the filter by tilting it forward then pulling up and out of the filter bracket.
(ill. W).
3. Slip the electrical wire out of its slot.
4. Release the motor from the filter body by squeezing the two release arms on the side
of the motor housing. (ill. X).
5. If the impeller needs cleaning, grasp the fan and draw it gently from the impeller well.
Rinse it under clean water. NEVER use soap or detergents, as traces of cleaning
(R)
products will harm fish. (ill. Y).
6. If the impeller well needs cleaning, scrub it gently with a Fluval Cleaning Brush.
In case of major cl eaning you need to remove the Impeller Shaft Assembly by
inserting the shaft tool (not Included) until you feel it engage at the base of the shaft,
then pull it up and out gently.
7. To replace, position the magnetic impeller on the shaft assembly and insert into
impeller well; push on impeller fan until the assembly locks into place.
(S)
The impeller will wear out over time. A replacement may be ordered from your local
Fluval dealer or by contacting our customer service at Rolf C. Hagen Corp.
