Setup Instructions
Before initial use, please read the full user guide PDF for detailed instructions. Below are general steps for setting up your EHEIM Jager Heater:
- Unpack: Carefully remove the heater from its packaging. Inspect for any visible damage.
- Placement: Position the heater vertically and fully submerged in your aquarium. Ensure it is placed in an area with good water circulation for even heat distribution. Use the included suction cups to secure it to the aquarium glass.
- Temperature Setting: Use the TruTemp dial at the top of the heater to set your desired water temperature. It is recommended to use an external thermometer to verify the actual water temperature and fine-tune the heater setting if necessary.
- Acclimation: Allow the heater to acclimate to the aquarium water temperature for at least 20-30 minutes before plugging it in.
- Power Connection: Plug the heater into a grounded electrical outlet. The indicator light will illuminate when the heater is actively heating.

- Temperature Adjustment: To change the temperature, gently turn the blue TruTemp dial at the top of the heater. Rotate clockwise to increase temperature and counter-clockwise to decrease it. Make small adjustments and allow time for the water temperature to stabilize before making further changes.
- Monitoring: Regularly monitor your aquarium's temperature with a reliable external thermometer to ensure the heater is functioning correctly and maintaining the desired temperature.
Maintenance
Proper maintenance ensures the longevity and efficiency of your heater. Always unplug the heater and allow it to cool completely before handling or performing any maintenance.
- Regular Cleaning: Periodically remove the heater from the aquarium and gently wipe down the glass tube to remove algae or mineral deposits. Use a soft cloth or sponge; avoid abrasive materials.
- Inspect for Damage: Before re-installing, carefully inspect the glass tube and power cord for any cracks, chips, or fraying. Do not use the heater if any damage is observed.
- Suction Cups: Check the suction cups for wear and tear. Replace them if they lose their grip to ensure the heater remains securely in place.
