Installation Note
●The heater has a built-in temperature switch. If the heater is exposed to open air during the
heating process, the heater will temporarily stop heating.
●The heater is for submersed use only. Place the heater completely in the water. Never expose
the temperature-sensing probe to open air during heater operation.
●Do not place the heater under the gravel. This will restrain the distribution of heat. Place the
heater horizontally at the bottom of the aquarium (above the gravel) where water circulates
freely. Using a water pump to create water circulation is recommended.
