MAINTENANCE

CAUTION: Always unplug any appliances from an outlet when not in use, before putting on or taking off
parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
FILTER MAINTENANCE
Prior to periodic maintenance the canister must be drained.
Drain the filter
1.
1. Turn the IN and OUT valves in sequence to the closed (horizontal) position.
2. Unplug the pump from the electrical power supply.
3. Remove the utility hose from the clips on the lid and position its end in an appropriate basin or
discharge drain.
4. Turn the utility valve to the open (horizontal) position by turning it counterclockwise. Then disconnect
the OUT valve.
5. Water will immediately begin to drain from the canister. Since this is a gravity fed method, water will
stop draining once the water level in the canister and drain bucket equalize. Once this happens simply
close the valve and empty the bucket. Repeat the draining process until enough water is removed to
make the canister light enough to carry to your work area.
Disassemble the unit
2.
1. Move the filter to an appropriate area convenient for maintenance.
2. Loosen and remove the eight lid fasteners; remove the filter lid and set aside. Be careful not to damage
the inlet stem connected to the lid.
3. Using the red T-handles, lift the media baskets from the filter canister; let the T-handles fall out of their
slots, and separate the baskets.
Cleaning or replacing media
3.
1. Remove all foam inserts from the media baskets and trays, rinse using aquarium or de-chlorinated tap
water, or replace with new foam, as required.
2. Rinse biological media with aquarium water, or replace, as
required.
3. Replace chemical media, as needed. Chemical media cannot be
cleaned.
4. Empty and rinse the filter canister. NEVER use soap or
detergents when cleaning the canister or rinsing the baskets
and trays, as remaining traces of cleaning products may damage
sensitive fish tissue.
5. NEVER overfill baskets. Leave at least 0.5 in. (1cm) of free space from the top of the baskets to the media, so
the baskets will fit together properly. If the red tray is present, the media at the bottom of the basket must not
exceed the height of the tray supports in the basket.

4. Pump care
FX4 IMPELLER MAINTENANCE
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. Prior to performing pump care the FX4 Filter must be completely emptied of water, media baskets, and media.
1. To remove the pump unit:
A. Place the filter unit upside down on a secure work area so that the pump screws and screw seats are
visible. Remember that the output tube protrudes slightly from the top rim of the canister. Be sure not to bend
or damage the tube while it is upside down.
B. Unscrew the 3 fixing screws using a Phillips screwdriver (cross headed).
Screws are located around the motor housing.
C. Remove the impeller assembly by grasping the fan and drawing it gently
from the well.
NOTE: There are 4 parts to the impeller:
D. Impeller shaft. The impeller shaft is held on both sides of the impeller well by
two rubber bushings. The shaft can be easily extracted by hand with care.
IMPORTANT: The shaft is made from ceramic, which is resistant to wear and
tear in use, but is fragile. Handle carefully during maintenance.
E. Front rubber bushing. If it remains in the red part of the canister, it's necessary
to remove it keeping attention to not damage it.
F. Rear rubber bushing. If the rubber bushing remains in its place, it's not neces-
sary to remove it.
G. Impeller assembly (Magnet + impeller fan)
2. Clean the impeller and the impeller well thoroughly by rinsing with clear
running water.
3. Re-assemble all pump components with care:
H. Replace seal ring if necessary: Remove it from the loophole. Please refer to the
"maintenance frequency chart". For this operation do not use any tools because
there is a risk of damage to the O-ring.
I. Re-assemble all parts in the following order: Rear rubber bushing at the bottom
of the well (if removed), ceramic shaft (pushing it until it stops); subsequently
the impeller assembly and at the end the front rubber bushing at the top of the
ceramic shaft. The shaft can be easily reinserted by hand; however, pay close
attention and be certain the rubber bushing does not become unseated.
4. Replace the pump unit with care into the canister and affix it using
the 3 fixing screws with a Phillips screwdriver (cross headed). While
re-assembling the pump, the 3 fixing screws should be gently screwed in
until pump motor cover and canister are securely attached.
NOTE: Do not over tighten housing to canister.
IMPORTANT: Be sure that the seal ring does not slip out of its seat.
