Checking the magnesium anode

The DHW warranty is void if the magnesium anode is not
correctly maintained.
The magnesium anode is a sacrificial anode that is consumed when the
DHW cylinder is in use. Two types of magnesium anode can be used.
Fitted as standard: A non-insulated magnesium anode ( Version A,
Fig. 25, page 65).
Available as an accessory: An insulated magnesium anode ( Version
B, Fig. 25, page 65).
We recommend that insulated magnesium anodes are additionally
checked regarding the protective current using an anode tester on an
annual basis ( Fig. 23, page 65). The anode tester is available as an
accessory.
Never bring the magnesium anode surface into contact
with oil or grease.
▶ Keep everything clean.
▶ Shut off the cold water inlet.
▶ Depressurize the DHW cylinder ( Fig. 15, page 63).
▶ Install and test the magnesium anode ( Fig. 24 to Fig. 27,
page 65).
▶ Replace the magnesium anode if its diameter has been reduced to
below 15 mm.
▶ Check the transition resistance across the earth connection and the
magnesium anode.
