Maintenance Procedures

Media Maintenance
Filter materials must be periodically replaced or cleaned. The various
Fluval media have instructions for use on the individual packaging.
Actual lifespan of any type of media varies according to usage and
the individual characteristics of an aquarium.
Unplug filter. Gently lift large blue center handle to release the Aqua-
f.1 f.2
Stop. To prevent drips or splashing when the Aqua-Stop
handle is lifted, place a cloth around it prior to disengaging. Internal
pressure often causes an unavoidable spurt of water when the Aqua-
Stop is released. The filter should be transported in an upright position to eliminate the possibility
of water splash.
***NOTE: Grip the filter canister body
from installation to maintenance area. The Lift-Lock Handles are designed to release the motor
housing from the filter case only. They should not be used as grasping points to transport an
intact filter. If used as carrying handles, there is the possibility of the unit separating and
water spilling.
It is not necessary to remove the hose system from the
aquarium unless the hoses or the Aqua-Stop require
cleaning. A clogged Aqua-Stop can result in a reduced
flow rate. Periodic cleaning is recommended to ensure
an optimal flow rate. In order to clean the Aqua-Stop or
hosing, rinse under water and, if necessary, use an
appropriate Fluval Cleaning Brush or tool.
Once the filter is in a waterproof place such as
a sink, raise the Lift-Lock Clamps to free the
motor housing from the filter case
See the section "Preparing the Filter" for
detailed instruction on Media Baskets.
IMPORTANT: Empty water from filter case before
proceeding. Tilt the unit over a sink while
holding the media baskets in place in order to
empty water from the filter.
Rinse or replace media as required. The filter case should be rinsed whenever the media is cleaned or changed.
NEVER use soap or detergents when cleaning. Any remaining traces may result in damage to sensitive fish tissues.
Replace Media Baskets in the filter case and slide in the Foam Screen Frame. To perform any required Impeller
care, see "Impeller Maintenance"section. Set the Motor Housing back in place. There is only one way in which the
unit can be properly assembled. Make sure the power cord is properly aligned with the indentation on the filter
f.6
case. Press motor housing down before locking it by closing the two Lift-Lock
f.7
Clamps . Return the filter to its original position. Guide the Aqua-Stop in place and
lock by pressing down the handle to a horizontal position. Water should start flowing
immediately, otherwise, pump the Self-Primer to restart.
Allow the filter case to completely fill before plugging the unit into power.
The Fluval unit should never be allowed to run dry. Plugging the unit in
before the filter case is full may prevent the self-priming feature from
working properly.
