MAINTENANCE
Impeller Care
The impeller well has an effective self-cleaning feature. However, it is a recommended that you
remove the impeller cover and inspect the impeller as part of your routine maintenance. Keeping
the impeller clean lengthens its life and the life of the motor.
IMPORTANT: The impeller fan has a ceramic shaft, which is resistant to wear and tear in use, but is
still fragile. Handle carefully during maintenance.
1. Remove the impeller cover: squeeze the two tabs, and lift off.
2. If the impeller needs cleaning, grasp the fan and draw it gently from the well. Rinse it under
clean water.
3. If the well needs cleaning, wipe gently with a Fluval Cleaning Brush.
4. Replace the impeller in the well:
a. Align the shaft so it is seated in the ring on the cover, and press the cover into place.
b. Slide the tabs outward until they "click" to indicate the cover is locked in position.
Models 105 and 205 only:
WARNING: The yellow ceramic impeller shaft is permanently
attached to plastic holder and is brittle to lateral pressure. Take
extreme care when handling the impeller.
Do not remove the ceramic shaft assembly unless it breaks. If
you should need to remove it: Insert the ceramic shaft tool until
you feel it engage at the base of the shaft, then pull up gently.
To replace, position a new magnetic impeller on the assembly,
and insert into impeller well; push on impeller fan until the
assembly locks into place.
Models 305 and 405 only:
The ceramic impeller shaft is held on the bottom of the impeller
well by a rubber support. The shaft can be easily extracted and
reinserted by hand; however, pay close attention to be certain
the rubber support does not become unseated. (Always replace
the impeller cover to ensure proper alignment).
The Impeller will wear out over time. A replacement may be ordered
from your local Fluval dealer or by contacting Customer Service at
Rolf C. Hagen Corp.
