Scale deposit can affect the heating
capacity of the heating element. Scale
can even cause the element to burn out.
The element can be descaled either
chemically or manually.
1. Remove the heating element. (See
above).
2. To de-scale chemically, soak the
heating element in white vinegar or
other descaling solution then rinse
well.
3. To de-scale manually, use a non-
metallic (soft) tool; brush the crust
off the element. Make sure you do
not damage the surface of the
heating element.
4. Reinstall the heating element

gasket. Make sure that both the
gasket and heating element are
positioned correctly.
5. Remount all the line wires from the
heating element to their original
location.
10. CHANGING THE ANODE ROD
A magnesium anode is used to extend the
life of the tank. Permanent removal of this
anode for any reason will void the
warranty.
Depending on conditions, the magnesium
anode rod may need to be changed every
year or so. Galvanic and electrolytic
corrosion can destroy a tank with a spent
anode rod. Rusty water is usually an
indicator of a spent anode rod.
