FLUVAL “E” SERIES with “
” Technology
Immediate and clear feedback for the well-being of your aquarium inhabitants!
The “E” series employs an advanced digital microprocessor monitoring system with dual
temperature sensors which continuously monitor and display the aquarium water
temperature. As well, it references the set temperature in relation to the actual water
temperature. During normal operation, when water temperature is within -1/+1 °C or
-2/+2 °F of the set temperature, the backlight of the LCD screen is green. If water
temperature exceeds the set temperature by 1 °C or 2 °F, the LCD’s backlight will turn red.
If water temperature is lower than the set temperature by more than 1 °C or 2 °F, the LCD’s
backlight will turn blue. If ever the temperature goes outside -/+3 °C or -/+5,5 °F of the set
temperature, the display will provide an alert by flashing.

*The heater is factory calibrated. Variables such as lower room temperature, wide
fluctuations, lack of an aquarium cover, presence of submersible pumps and filters,
aquarium placement in proximity to cooling sources, may require a higher wattage for
proper control. The volumes indicated are approximate values corresponding to water
temperatures up to 26°C/78°F with a room temperature of 20°C/68°F. If the ambient
temperature is higher than the set temperature of at least 1°C/2°F, or external sources of
heat elevate the aquarium temperature more than 1°C/2°F, the LCD display will remain red
untill conditions change.

THERMAL SENSOR
The temperature sensing technology as precise as an external probe!
The internal Thermal Sensor samples the actual water temperature directly through the
glass of the heater tube rather than the air temperature within the tube, as is the case with
standard bi-metallic strip thermostats. Since the Thermal Sensor actually reads the true
water temperature, it is more accurate and reliable than conventional bi-metallic heaters.

RELIABLE AND PRECISE ELECTRONIC COMPONENTS
Advanced Electronic Circuitry, no moving parts to wear out!
Since the FLUVAL E heater has no bi-metallic points, there are no moving parts to arc,
corrode or wear. The thermostatic control of the heater is separated from the water
thermal sensor, different from conventional bi-metallic heaters, where the sensor is directly
built into the thermostat. It is therefore less affected by extraneous factors.

INSTALLATION
It’s recommended to fill the aquarium with water that is close to the desired
temperature you are trying to achieve.

To ensure even and thorough distribution of warmed water and to provide an accurate
temperature readings, the heater must be placed in close proximity to a source of water
movement. Specifically, it should be placed at the rear of the aquarium, close to a filter or

1. Position the heater in the aquarium and press suction cups firmly against glass, to
adhere to the aquarium wall. If rear glass mounting is not possible, use the side glass
mounting adapter (ill. A). To fit the side mounting bracket, first remove the suction cups
from heater bracket, and place them in the slots of the side mounting bracket. (ill. B and
