IMPORTANT: Do not plug in heater until instructed.

Attach the suction cups included with the heater to the Mounting Bracket. Slide the bracket over the heater and position bracket so it is snug to the top of the heater thermostat.

Place your heater into your aquarium, ensure that the heater is fully submerged underwater. All Cobalt Aquatics Heaters are fully submersible and should be so to ensure that they are able to correctly read the temperature of your aquarium. Choose an algae-free location and ensure the heating element is not touching any gravel, decoration, or other surfaces and firmly press the suction cups against the aquarium or sump.

Wait at least 15 minutes before pluggin in your heater. When first plugged in the LED's will circle and then display the set temperature and current tank temperature. NOTE: Before plugging in heater, create a "drip loop" to prevent water from reaching any electrical source.

Select the desired temperature by pressing the appropriate button or by turning the appropriate dial. For all Neo heaters, temperature will increase by 2 degrees for each button press. Once the temperature reaches maximum, the next press of the button will cycle the temperature to the lowest temp again. Keep pushing the button until you reach the desired temperature.

Maintenance: To ensure accurate temperature control, regular cleaning of the heater exterior by removing any algae or mineral deposits is recommended.

Special Note for use with Aquarium Controllers: Please set controller temperatures higher than that of your heater.

APEX users: Please be sure to plug your Neo Heaters into Plug 4 or 8.

Digital Auqatics users: Neo Heaters can be plugged into any port without issue.
