Amazon.com Directions for installing and using your Aqueon ProHeater Caution: Before working with or installing heater, be sure to read and understand all safety instructions and warnings. Step 1 Attach suction cups: Remove sticker around power monitor light. Attach suction cups to heater. Attaching both suction cups will ensure proper positioning in your aquarium and will allow adequate water circulation around the heater for even heat distribution. Suction cups should be placed in the middle to upper portion of the heater. Step 2 Set heater temperature: Turn the adjustment knob until it corresponds to the desired aquarium temperature. As all aquariums vary, further adjustment may be required to maintain desired temperature. Step 3 Heater installation: Install heater in water filled aquarium. The heater works best when installed in the aquarium in the vertical position. The installation of the heater in this position requires that the aquarium must maintain a water level above the minimum water level on the heater. The heater can be installed in the aquarium in the horizontal position. The installation of the heater in this position requires that the heater be positioned fully submerged in water at all times. Step 4 Plug into electrical outlet: Allow for heater to be submerged in water for a minimum of 30 minutes prior to powering the appliance. Once heater has been mounted and submerged for the 30 minutes, plug the appliance into an electrical outlet. Once plugged in, the heater will automatically start working and the power monitor light will illuminate. A red light indicates the unit is heating and a green light indicates the unit has reached the set temperature. Step 5 Adjust temperature: Allow the heater to run for 24 hours at the original setting prior to adjusting. Check the aquarium water with a reliable thermometer. Should the heater need to be adjusted from the original setting, slightly turn the adjustment knob + or - the number of degrees, as needed. Once adjusted, wait 24 hours and repeat if necessary. Note: Do not over adjust the heater, this may cause harm to your aquarium inhabitants and environment. Make sure of the required temperature for your specific setup.
