With the EHEIM JÄGER precision heater your fish receive exactly the right temperature – in any aquarium.
Obvious ideas often are the best ones. For example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it. It is true that the principle is still the same as decades ago. But a lot has changed in the meantime. And today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available technology. A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission. And no matter if you want to heat a 20 or a 1000 litre aquarium – you have 7 sizes to choose from.
Benefits of the EHEIM JÄGER thermostatic heaters
Precise temperature adjustment from 18 up to 34 °C
Simple and safe recalibration (±2 °C)
Temperature control accuracy ± 0,5 °C
Heat kept at a constant level
Heating function is indicated by a control lamp
Completely submersible (watertight)
With automatic dry run shut-off (Thermo Safety Control)
A glass jacket increases the heating surface and ensures optimum even heat emission
Handy cable length ca. 170 cm
Including double suction cup holder
9 sizes for aquariums from 20 up to 1000 litres
Suitable for fresh and salt water
Installation Instructions:
Check device for damage.
Remove transit protection.
Fix suction cups to double suction cup holder and clip onto heater (not near the heating spiral).
Mount thermostatic heater with double suction cup holder vertically in the aquarium, fixing it in a place where water flow is brisk (filter outlets/vents).
Set temperature.
Plug into electrical outlet.
Setting temperature
Turn the temperature selector ring to the desired temperature.
Monitor the aquarium water temperature using an accurate thermometer for at least 24 hours and make any necessary adjustments to compensate for calibration errors.
You should periodically monitor your aquarium water temperature with an accurate thermometer (Red light = heater in operation).
Note: The temperature selector ring should only be used as a guide. Always use an accurate thermometer for water temperature measurement.
Recalibration
If, after a day or two in operation the setting scale does not correspond to the water temperature, refer to the following procedure to recalibrate the heater:
Switch off the heater and unplug it from the electrical outlet.
Measure the water temperature with an accurate thermometer.
Turn indicator arrow (red) point to the measured temperature.
Set the desired tank temperature with the temperature selector ring (blue).
