Maintenance - Fluval E-Serie Gebrauchsinformation

ill. C) The three protruding arms of the side mounting bracket are then clipped into the
revealed slots of flat heater bracket (ill.D). Important: Place the heater where the unit
is unobstructed, and where there is a free flow of water to ensure even heat dispersion.
Ensure that the heater is positioned so that the aquarium water level is never below the
MIN indicator found on the guard of the heater. If necessary, you can simply adjust the
heater height by sliding it along the bracket, by squeezing the two release arms on the
side of the heater guard. Be sure there are no rocks, decorations or gravel obstructions
touching the heater to create uneven heat.
2. Allow heater to acclimatize in the aquarium water temperature for 20 minutes before
plugging it into the electrical outlet. Be sure to arrange a drip loop for the heater cord
and any other electrical item that is placed in or on the aquarium.
3. After 20 minutes, plug in the heater and set the degree scale if necessary (refer to the
paragraph "HOW TO SET °C OR °F DEGREE SCALE" below) and the aquarium
temperature (refer to the paragraph "HOW TO SET THE AQUARIUM
TEMPERATURE" below). Once set, there is no need for readjustment.
4. At each Power-on, the E Heater goes through an initial self test procedure during which
it carries out a self-diagnosis to check internal circuitry and sensors operation, followed
by a period to verify the surrounding conditions. The self-diagnostic check requires
several minutes to complete, during which time the E heating element is switched on
for a few seconds only to verify the heater operation and application conditions. After
the self-diagnosis is completed, the E Heater starts its standard operation. During the
self-diagnostic test, the LCD screen will display the water temperature.
WARNING: The heater must never be operated outside of the aquarium. If the water level
falls below the minimum water level MIN, the thermostat can no longer "read" the water
temperature and therefore can no longer control the heating correctly. If it has to be taken
out of the water or when transferring or changing the water, disconnect the heater from the
power source and wait for at least 30 minutes to allow it to cool down.
HOW TO SET °C OR °F DEGREE SCALE
The heater is factory set on the °C degree scale for 50 Hz markets and °F degree scale for
60 Hz markets. In case you need to change the degree scale, hold the set lever in the full
left (-) position for at least 5 seconds (ill. E). When the new degree scale is displayed, you
may release the lever. After a few seconds, the display will automatically return to display
the water temperature (ill. F).

HOW TO SET THE AQUARIUM TEMPERATURE
The heater is factory set at 25 °C / 77 °F. If a different water temperature is desired, use the
easy set lever on the top of the heater. Push the lever to the right or left and release; the
LCD screen will start to flash showing the set temperature (ill. G and H). Each subsequent
(C)
(F)
(G)
push of the lever to the right or to the left will increase or decrease the set temperature by
(D)
0.5 degree intervals (°C or °F). Once the adjustment has been made, release the lever. After
a few seconds, the display will stop flashing and will return to the normal working condition
displaying the aquarium water temperature.
INTELLIGENT ERROR MESSAGES
The advanced E Heater microprocessor detects and displays some abnormal or non-
optimal usage conditions, which require verification and proper action by the owner. The
possible error codes are the following:
Displayed Error Code Heater Status
E1, DISPLAY IS FLASHING, The "E" Heater has gone into error
ALL COLORS ARE status and has removed power from the
ALTERNATELY DISPLAYED heating element. This error status can
only be reset by unplugging the unit.
LF (LOW FLOW) IS The "E" Heater will keep on operating,
DISPLAYED EVERY FEW although its proper operation is
SECONDS inhibited due to poor water circulation
around the heater.
The error status will be automatically
reset once adequate water circulation
around the heater has been provided
and the heater has had time to re-
calibrate itself..
WARNING: This aquarium heater must never operate outside of water. If the heater is accidentally
removed from water while operating, DO NOT re-submerse it in water. Unplug it and let it cool
down for at least 1 hour before reusing.

MAINTENANCE

CAUTION: Unplug all appliances in the aquarium
before carrying out maintenance. Unplug the
heater and allow it to cool for at the least 30
minutes before taking it out of the water.
Clean the heater guard and the glass tube regularly to
remove encrustation and deposits that could impair the
heating performance and the sensitivity of the
thermostat.
1. Remove the heater from the suction cups bracket by
squeezing the two release arms on the side of the
heater guard and separating it from the bracket (ill. I).
2. In order to reach the internal glass tube, remove the
heater guard as explained in the paragraph "REMOVE
THE HEATER GUARD FROM THE UNIT" below.
3. Clean the heater glass tube regularly to remove deposits that could impair the heater
performance. Deposits on heater can be removed by soaking the heater tube in
vinegar, then rinsing with fresh water before repositioning in aquarium.
4. Clean the heater guard under a stream of water, assuring that all openings are free
from dirt and debris. If required use a soft cleaning brush.
HOW TO REMOVE THE HEATER GUARD FROM THE UNIT
Once the heater has been removed from the aquarium and suction cup bracket, you
can remove the heater guard and have access to the internal glass tube. Using a
(H)
flathead screwdriver, slightly lift the secure lock tab at the back of the heater cap to
free and remove the heater guard, as shown in the pictures below.
Possible cause and solution
The "E" Heater has detected an abnormal
usage condition.
Unplug the heater.
Check that all application conditions are
correct according to the instructions,
including the respect of the MIN water level.
Start up the heater again following the
"Installation" instructions above.
The "E" Heater has detected poor water
circulation around the heater. The even and
thorough distribution of warmed water inside
the tank could be limited by the inadequate
circulation. Ensure adequate water circulation
around the heater and inside the aquarium.
Verify installation conditions outlined in the
"INSTALLATION" instructions
