After these steps, the process of putting the water heater into operation is the same as if a new
water heater was put into operation.
Active anode
As a supplementary accessory, the hot water tank is equipped with an active anode to protect it against
corrosion. The life expectancy of the active anode depends on the conditions of water and operation. The
state of the anode has to be checked during periodic maintenance measures targeting scale removal or at
least in every second year.
The date of repeated check is defined by the repair technician. If the diameter of the anode shrinks to 10 mm
at any points, it has to be replaced. The replacement of the active anode can only be performed by a
contracted service shop (see the commercial warranty!).
After the replacement of the active anode, its earthing has to be set according to its original state. It is
extremely important to ensure a good metal contact between the active anode and the earthing screw
.

3. The water heater should be drained with the help of
the safety blow-off button (turning the operation button).
