periodic maintenance.
e. The water temperatures in the storage vessel do not exceed the maximum setting of
the thermostats, which form a part of the storage vessel.

Particular attention should be paid to the ends of each anode to ensure excessive
localized depletion has not occurred. Where anodes are covered with particles they
should be cleaned; for reference, when new, the anode has a diameter of 21 mm.
When power anodes are used, it is important to ensure that they continue to work
properly.
