Control your aquarium's temperature safely and precisely with the THEO aquarium heater. The THEO is suitable for marine and tropical aquariums. The THEO heater can be positioned in any way: vertically, horizontally, or submerged. High quality components are used, including a shatter proof glass tube and a patented PTC heating system that guarantees safety and shock resistance.
Directions: INSTALLATION Caution: before placing your hands inside the tank, disconnect all electrical appliances from the mains.
Check the voltage to verify that the one reported on the heater label corresponds to your electrical supply mains.
Fix the suction cups supplied to the heater.
Place THEO in the tank in an area which enjoys good water circulation, as this will assure even heat distribution and most effective heater operation.
Place the suction cups on the previously cleaned glass and press firmly.
In order to ensure that heater works properly, you should be careful not to let the level of the water, in case of vertical positioning, drop below the "WATER LEVEL - TAUCHTIEFE - NIVEAU D'EAU - LIVELLO DELL'ACQUA" line.
In order to set the heater, turn the knob until the temperature indicator corresponds to the required temperature value.
Connect the heater to the supply mains and wait a few minutes, allowing it to adapt to the temperature of the water.
Should the water temperature turn out to be lower than the value set on the graduated scale, THEO starts working automatically, and the light comes on and remains lit while the heater is in operation.
Once the set temperature is reached, THEO will maintain it automatically
