Magnesium Anode
Magnesium Anodes serves to neutralize corrosive substances in the water and will
run out in a certain time depending on the corrosive properties of the water. If the
water has good enough quality (PAM), Magnesium Anodes should be replaced
within 2 (two) years. If the water quality is not good, Magnesium Anodes should be
replaced in maximum 1 (one) year period of time. To replace Magnesium Anodes,
contact MODENA Call Center.

If the water contains limestone (Mud), the heating element cannot function properly
(slow heat) because it was covered by a crust of limestone (mud). Therefore, heating
element must be cleaned off from the sediment each year. To do this cleaning
procedure, contact MODENA Call Center.
