ZINC ANODE: A Sacrificial Zinc Anode is supplied on the shaft of all De-Icers for protection of the
equipment from corrosion and electrolysis. It is extremely important that the zinc anode be updated
(replaced) if reduced to half the original size or if white in color. Corrosion from electrolysis is more commonly
associated with saltwater or brackish water, but as a matter of precaution, it is important to periodically
check the zinc anode in all installations (at least every two to three months; monthly in saltwater).
