Fluval Media Selection - Fluval MSF 104 Mode D'emploi

Alternate new media introduction
Filter media should be changed at the regular recommended intervals. However, not all media should be replaced at one
time. Stagger filter media changes so there is always old filter media in the filter. This enhances replacement of important
bacterial colonies lost with discarded media. It promotes rapid seeding for continued bacterial action within the filter.
To further heighten the bacterial filter, use Nutrafin Cycle Biological Aquarium Supplement once a week to institute,
supplement and promote the correct beneficial bacteria and to encourage them to become the dominant strains within
the bacterial filter.
WARNING
The power supply cord of this appliance cannot be replaced; if the cord is damaged, the appliance
should be discarded. Disconnect the plug from all appliances inside the aquarium before putting hands
in the water. The pump must never be allowed to run dry.
Impeller Maintenance
Important: these motor units contain an Impeller Fan with Ceramic Shaft. This kind of
shaft is more resistant to wear and tear but it is fragile. Special care is recommended
during maintenance.
The impeller well has an effective self-cleaning feature. Regular monitoring for dirt
build-up can help lengthen the life of the impeller and motor unit.
To access the impeller, remove the impeller cover by squeezing the two tabs.
The Magnetic Impeller should be cleaned when necessary. To remove it, gently grasp the
impeller fan and withdraw it from the well and rinse off under clean water. Check that the Impeller Well is clean.
If necessary, use a Fluval Cleaning Brush to clean it out. Then reinsert Impeller.
When maintenance is complete, place the Impeller Cover (X) into its seat again and lock it in place by pushing down all
around the edges and then pushing the tabs outward until a slight "click" is heard (make sure that the Impeller Shaft is
properly reinserted into the shaft support ring of the Impeller Cover).

Specific notes concerning Fluval 104 and 204
The Fluval 104 and 204 models come with a ceramic shaft, which is attached to its yellow plastic support (Ceramic Shaft
Assembly). It is not recommended to remove the Ceramic Shaft Assembly unless it breaks. To remove the yellow Ceramic
Shaft Assembly from the Impeller Well use the provided Ceramic Shaft tool (Z)
To reinsert the Ceramic Shaft Assembly: place the Magnetic Impeller (W) on the Ceramic Shaft Assembly and reinsert
them into the Impeller Well by pushing gently on the Impeller Fan to lock them in place.
Specific notes concerning Fluval 304 and 404
The Fluval 304 and 404 models come with a Ceramic Shaft fixed on the bottom of the Impeller Well by a Rubber
Support. The Ceramic Shaft can be easily extracted and reinserted by hand, paying close attention to the Rubber
Support to ensure that it has not come out of its seat
proper alignment.
The Impeller will wear over a longer period of time. Replacement parts may be ordered from your local pet dealer
(see "Fluval Spare Parts" list).
