Installation
Caution: Before placing your hands in the tank, disconnect all electrical appliances. Be sure that the voltage of the mains corresponds to the voltage shown on the heater label.

The heater must be installed outside of your tank by cutting the outlet tube of the external filter, and by connecting the two parts of the tube onto both sides of the heater.

If the external filter is already installed, it is important to shut off the valve taps, to empty out all the water that it contains, before cutting the outlet tube. The presence of air bubbles inside the heating unit can cause irreversible damages. Make sure that HEATER is installed in a vertical position and follow the flow direction of the water that is indicated on the heaters body with an arrow.

Reactivate the aquariums water circulation and connect the new heating system to the mains. After the first 24 hours of operation it is advisable to check all connections are tight.
