Instructions
Remove the submersible aquarium heater and the suction cups from the package.
Remove the twist ties from the cord.
Examine the aquarium heater for breaks in the glass or plastic housing.
Clip the suction cups approximately one to two inches from each end of the submersible heater.
Set the temperature switch. There should be an arrow or band of color denoting the ideal temperature for an aquarium. Set the gauge to within this mark.
Place the aquarium heater in a pot of water deep enough for it to be submerged and plug it in.
Check the aquarium heater in three to four hours to ensure it is heating properly. Insert a thermometer and check the water's temperature. It should be between 69 and 80 degrees Fahrenheit.
Install the heater in the center of the back of the aquarium, at least three inches from vegetation, fake plants and other aquarium devices. Press the suction cups firmly to the wall of the aquarium.
Plug the heater into a surge protector or wall outlet; establish a "drip line" with the aquarium heater cord.
