MAINTENANCE PUMP CARE
Pump Care: Impeller Maintenance
WARNING: ALWAYS DISCONNECT ALL APPLIANCES IN THE AQUARIUM FROM ELECTRICITY 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.
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 FX6 Filter must be completely emptied of
water, media baskets, and media.
1. Empty the filter canister by following the steps outlined in the Media Care Section. Move
unit to appropriate work space.
2. Remove all media baskets with media from the filter canister. Empty the canister completely
in a sink or basin.
3. 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 4 fixing screws using a Phillips screw-driver
(cross headed). Screws are located around the motor housing.
c. Remove the impeller assembly by grasping its flange (black
disc).
4. Clean the impeller and the impeller well thoroughly by rinsing
with clear running water.
5. Reassemble all pump components with care:
a. Align the two arrows on the impeller assembly. Before
inserting the impeller, gently press the magnet against the flange
to be sure that the flange bushing is fully in its seat.
b. Replace seal ring.
6. Re-attach the pump unit to the canister using the 4 fixing
screws with a Phillips screw-driver (cross headed). While re-
assembling the pump, the 4 fixing screws should be gently screwed
until pump motor cover and canister are securely attached. Note: Do
not over tighten housing to canister.

Though the bushing is made of very resistant material, it is
prone to wearing in certain conditions. For this reason, it
