ANTI-CORROSION PROTECTION – MAGNESIUM ANODE (FOR WATER HEATERS 

WITH WATER TANKS COVERED BY GLASS-CERAMIC OR ENAMEL COATING)

The magnesium anode provides additional protection to the water tank’s inner surface 

from corrosion. It is an element undergoing wear and tear and is subject to periodic 

replacement, which is at the expense of the user. In view of the long-term and accident-

free use of your water heater, the manufacturer recommends periodic inspections of 

the magnesium anode's condition by a qualified technician and replacement whenever 

required, and this could be performed during the appliance's technical preventive 

maintenance.

For replacements, please contact the authorized service centres or a qualified technician!
