Checking The Magnesium Anode; Re-Commissioning After Performing Maintenance - Buderus S 32/5 Notice D'installation Et D'entretien

9.1.3 Checking the magnesium anode

If the magnesium anode is not serviced properly, the
warranty is void.
Annual service records must be kept in a safe location
and submitted together with the original purchase
receipt in the event of a warranty claim.
The purpose of the anode rod is to protect the tank against corrosion. It
is critical that the anode rod be inspection once a year to determine
whether it requires replacing.
Upon inspection, the anode rod surface should appear smooth. If the rod
surface appears pitted, bumpy, rusty, scale has built up on the surface,
or if the rod is less than 5/8" (15 mm) in diameter, then it must be
replaced.
Certain installations may require more frequent replacement of the
anode rod:
• Recirculation applications,
• Poor water quality,
• Galvanic/electrolytic corrosion,
• High flow applications.
In the event of poor water quality it is recommended that a water
treatment professional be consulted for water treatment options.
Damage resulting from failure to replace the anode rod is not covered
under tank warranty.
Never bring the magnesium anode surface in contact
with oil or grease.
▶ Keep everything clean.
▶ Shut off the cold water inlet and DHW outlet.
▶ Depressurize the tank.
▶ Remove and inspect the magnesium anode.
