Directions: 1. Attach the suction cups (included) to the double suction mounting bracket. Slide bracket over heater to position indicated. 2. Place heater in aquarium by firmly pressing suction ends against wall surface. The three-position viewing window allows you to view the temperature setting from three possible angles, simply turn the heater until it locks into the best viewing position. Note: Choose an algae free location with adequate circulation. This ensures even heat distribution and optimum operation. No part of the heater housing should contact aquarium gravel, rocks or decorations. 3. Wait at least 15 minutes before plugging in your heater. The on off indicator light will confirm that the power is on. Note: Before plugging in heater, create a drip loop: to prevent water from reaching receptacle. 4. Select the desired temperature. Turn the "Click Set" temp select dial until the point of the red light on the thermometer scale reaches the correct setting. Most tropical fish like 78*F - 81*F water. Note: It is recommended to use a tank cover to prevent water temperature variances to heat loss. Both can impair heater performance, create a hazardous environment for the fish.
