Please note

A short circuit between the mag-
nesium anode and internal indi-
rect coil increases the protective
effect of the magnesium anode
and leads to corrosion damage
on the DHW cylinder.
Before inserting the electrical
cables, measure the resistance
between terminals

A

and

B

. If

the resistance is significantly less
than infinity, check whether the
magnesium anode is touching
the internal indirect coil.
