off with a clout. After that, the appliance must be rinsed thoroughly and the heating process
is checked the same as during the initial putting in operation. Do not use any abrasive
cleaning agents (such as liquid sand, chemicals - acid, alkaline) or dye thinners (such as
cellulose thinner, trichlor, and the like) to clean the outer shell of the heater. For cleaning
use a wet clout and add a few drops of liquid cleaning agent for household applications.
