The thermometer indicating the temperature of water in the tank, and the "anode tester" for the
control the active anode status are installed in the plastic cover of the appliance.
The thermometer sensor is placed in the pocket tube located on the closing cover of the upper
service opening of the appliance. This pocket tube hosts sensor of the control unit, and the said cover
hosts the active anode providing the secondary corrosion protection of the tank.
The inner surface of the water heater tank is protected against corrosion by a special enamel coating,
which is also added the active anode as secondary protection. This ensures long service life for the
tank with the most aggressive waters even.
The height of the legs of the appliance can be adjusted at 20 mm intervals.
The main dimensions and connection specifications are illustrated in Figure 1.
